Build log: Project Sandy Obsidian

Somewhat of a continuation from my thread in the main Liquid Cooling forum (http://www.xtremesystems.org/forums/...d.php?t=264246), I'm building a Sandy Bridge system in a 700D case to replace my aging Opteron 165 that's served me faithfully for the last 4 years.

My goal for this system is to have a screamingly fast silent system to last me for another 3+ years. With that said, the hardware I'm going with is as follows:

i7-2600K
Gigabyte GA-P67A-UD7
4X2GB Corsair XMS3
Zotac GeForce 580GTX
OCZ 120GB Vertex 2 SSD
Samsung 2TB HDD
Lite-On Blueray burner
Corsair 850AX power supply

Based off of the advice received from forum members, I'm looking at the following watercooling hardware to make things nice and quiet:

CPU Block: Swiftech Apogee XT. I was trying to decide between this and the EK Supreme HF, but the mounting system won me over in the end.
GPU Block: EK 580GTX Full Cover block
Rad: Swiftech MCR320 or MCR420 for the top of the case, MCR220 or MCR320 (if I can fit it) for bottom of case.
Fans: Gentle Typhoon AP-15s if I can get them, AP-14s if I can't, not sure if I need to find a good 140mm fan to replace stock ones or not.
Pump: Swiftech MCP35X
Reservoir: DD Monsoon bay res.
Fittings: Compression Fittings (Bitspower or Fesser most likely, only difference AFAIK is price, right?) for blocks, pump, and reservoir, and a t-line leading to drain plug.
Tubing: Clear tubing 3/8"ID 5/8"OD (Primochill LRT or Fesser).
Fluid: Distilled water + PT Nuke and/or Kill Coil
Fan Control: ???

My first priority is to get the new hardware up and running in a temporary case to make sure everything works nicely, and then move it over into the 700D once I've got the watercooling setup. Before I can do that however, I still need to nail down a few missing tidbits of information:

Will 3/8" ID 5/8" OD compression fittings work on the Apogee XT, or do I need to use an angled fitting or barbs instead? (I would like to avoid flipping the intake plate if I can avoid it.)

This question can alternatively be phrased as what is the overall diameter of the various 3/8" ID 5/8" OD compression fittings? I believe I can figure out clearance by referring to the drawings Swiftech has posted.

What is my best option for fan control and system monitoring? I would ideally like a solution such as the t-balancer, a TMS-200, an aquareo, or similar since being able to monitor everything in software would be a definite plus. I could, however, use something like a Lamptron FC Touch instead, however my selection seems a bit limited as I am trying for a very minimalist look for the front panel and a controller with lots of knobs would spoil the effect.

In short, I need to do some more research on this point before making up my mind, in the meanwhile, I'll have to live with this for cooling :(

Unfortunately, the action is going to have stay fairly restrained for now as the Sonata III isn't exactly the best case in the world to use for overclocking. :(

Unfortunately, I didn't think to save ORB links. Also, the results page contains the caveat that the drivers aren't approved (I'm running the new beta drivers from the 4th), and on my new rig, that GPU physx is enabled (note, I just left all settings at default).

wow the new pc is killing your old one using 3dm11!

Yeah, I'm kind of impressed by the gains from going to the newer architecture. I can't wait to start overclocking it.

Also, I heard back from Gabe at swiftech about the spacing of the inlet/outlet on the Apogee XT, and unfortunately, it's 21.2mm. This means that the bitspower 5/8" OD fittings won't work as according to Penguins, they have an OD of 21.92mm.

I need to track down ODs for Feser and Enzotech fittings to see if they might fit.

I'm also starting to lean towards an Aquaero, but want to wait until the new one that Shoggy is posting about is released, I suppose I can live with loud fans in the interim if necessary.


Edit: Unfortunately, Enzotech fittings weigh in at 22mm, and while I can't find a solid number for their 5/8" OD fittings, Feser's 1/2" OD fittings have a diameter of 20mm, so I really doubt 5/8" fittings would fit.

I'm thinking about using thin-walled tubing to and from the CPU block and thickwalled everywhere else for kink resistance.

45° adapter or rotate the inlet plate
don't worry you won't lose that much flow ^^

I might be able to get by with a single 45 degree rotary, and a normal compression fitting on the inlet port, the bitspower rotary fittings have a shaft diameter of 18mm.

22mm/2 + 18mm/2 = 20mm, leaving me with 1.2mm of space between the two fittings. Not a lot of space, but enough, in theory.

The other ideas that I'm toying with are hiding most of the tubing to/from the rads behind the motherboard tray, Dazmode did it for their 800D build, and I think it would look better than running a tube all the way along the top of the case right in plain sight.

I suspect I'll take some time and toy around with possible routings in Paint to figure things out. I can afford to take my time here as the system is up and running in the Sonata III for the moment (though limited on the OC for cooling reasons).

In terms of WC Parts, here's where I am right now:
Apogee XT
MCP35X
MCR420
MCR220
EK-FC580 Nickel Plated
10 ft Primochill Primoflex Pro LRT Clear 3/8" ID 5/8" OD
6 Scythe Gentle Typhoon AP-15 or AP-14
Either DD Monsoon bay res, or Swiftech MCRES tucked away somewhere (bay res is definitely sexier, MCRES is slightly more stealth)
1 T fitting for drain line
1 plug for drain line
12 fittings (2 each, 2x Rad, CPU WB, GPU WB, Res, Pump)
Min of 1 45 degree fitting (CPU WB)

To round out the list of stuff, I have a few more questions that I need to find answers to before I can go and pull the trigger on the loop.

While I really want to do compression fittings from a looks perspective, I'm not putting a window in the case, and I could cut fitting costs in half by going with barbs (pair of barbs for under $6 and $7ish vs single compressions for $6-8). Is there any reason why going barbs is a bad idea relative to compressions? (Note, I would very much be using hose clamps)
If I were to put a single temperature sensor in the loop, where would the best place to put it be? What about a second sensor, does it make sense to include a second sensor elsewhere?
For a flow sensor, I assume I could place it anywhere in the loop, right?
As a follow up to the last two questions, any recommendations for brands of temperature and flow sensors, or are they all roughly created equal? I'm tentatively planning on an aquaero.

I am this close to pulling the trigger on an order from NCIX, all the watercooling components less fittings will qualify for cheap express shipping (adding the fittings pushes me over the weight limit for express shipping, and regular shipping would cost about as much as the cheap express).

I'll sleep on it, but I think I'll order the rads, blocks, pump, fans, and tubing from them, and figure out what I'm going to do for fittings separately.

Well i go for compressions because of the bling they bring to the loop, for me barbs are old school and after using compressions i'd never go back kinda make the build look cheapish :D , If your not using a window you should of just gotten a Bench setup woud look quite slick mate!. As for the sensor i'd stick it after the rad as that would give you the best temp readings..

Thank you for the input Johnny, I'll ponder the actual total cost of barbs versus compressions, and see what I arrive at I suppose.

While I have seen some very nice looking bench setups, it wouldn't fit my space unfortunately, my computer desk is filled by a pair of monitors, and I don't have anywhere else that I could put it close by, out of the way, and easy to get at for when I need to put a disc in the drive. :(

Also, I prefer an entirely enclosed system as it's a bit harder to damage accidentally. WRT to a window, I'm not planning one ATM, but I might change my mind later, I think I've still got a sheet of plexi kicking around from a failed build years ago.

Also, while sticking the temperature after the rad would give me the lowest water temps, and letting me gauge the delta T between water and CPU block, wouldn't sticking one in the res best let me gauge the delta T between water and air?

On a side note, assuming an aquaero can deal with two-wire temperature sensors (I know the BigNG with SensorHub can, but I'm a bit apprehensive about using a product that the manufacturer no longer supports), Bitspower sensor plugs seam reasonably cheap, so sticking 2 in the loop doesn't seem that bad either, and then I could actually figure out the heat output of the loop if I knew the flowrate...

The cost difference is quite a bit once you get up to a bunch of fittings. if you have only a few spots the cost difference is only so much.


The first WC build i had Koolance Barbs and Worm Clamps! i hated it!
Second had crappy Comps, I hated it!
Third build BP Compressions and i <3 them.
This new build i'm working on has barbs and compressions depending on what the components are.

My #1 pretty = barbs with no clamps ( course use at your own risk and even then... a quiet computer is paranoia enough let alone one that might have actually leaked lol )
#2 Compressions
#3 Barbs with simple nice looking clamps.

After recent examination of my BP Compression fitting to measure for you I was kind of scared of them.. there really isn't much keeping these compression fittings on the tube.

Can't you change the plate on the XT to accommodate the bigger compression fittings?

I could, but for asthetic reasons (kind of silly given that there won't be a window for now at least), I'd really rather not.

Pulled the trigger on the blocks, pump, rads, tubing, and fans. NCIX is showing stock of Gentle Typhoon AP-15s, which is what pushed me over the edge into ordering now.

Woot :D , now its just a matter of assembling the beast :)

Almost, I've still got a few things left to get, fittings, reservoir, rad grills, intake filter, kill coil, and possibly fan extensions. But you're right, once the stuff from NCIX arrives, I can get started on putting things together.

some pictures?

I'll get some pics up later today of the system up and running in its temporary home, real excitement gets to wait for the WC gear to arrive next week. :)

As mentioned, a few pics to tide you over, what it looks like in its temporary home, and some HyperPi action.

I'm actually pleasently surprised with how cool running the 2600K actually is, even in a case with such relatively poor airflow as a Sonata. I'm loving the AX850 power supply as well, the fan doesn't turn on until a certain thermal load is reached, which means that at idle it shuts off completely. If not for the Tricool and the HSF on the 580GTX, the computer would be near silent at idle, as it is, it's just very quiet, and ramps up under load as the CPU fan (a Scythe Kaze PWM fan), the GPU fan, and the PSU fan start to ramp up. This will all change soon enough. I'm expecting my order from NCIX to arrive in the next couple of days, then I can get started on the modding and figuring out what fittings I need and getting them ordered.

now pics with the loop all tied up :D

Unfortunately, I have both good news, bad news, and a question...

The good news, my order arrived from NCIX today, the EK FC waterblock and Swiftech Apogee XT look sweet, and I did, in fact, manage to get my hands on 6 AP-15s for my rads. :D

http://www.images.atragon.org/main.p...&g2_itemId=987 http://www.images.atragon.org/main.p...&g2_itemId=991http://www.images.atragon.org/main.p...&g2_itemId=995 http://www.images.atragon.org/main.p...g2_itemId=1019 http://www.images.atragon.org/main.p...g2_itemId=1023

The bad news, the baggie for the MCR220's screws comitted suicide and let the screws escape into the box, I'm not sure if that's the cause or not, but there is a big chip in the finish on one of the end tanks of the 220. :(

http://www.images.atragon.org/main.p...&g2_itemId=999http://www.images.atragon.org/main.p...g2_itemId=1003http://www.images.atragon.org/main.p...g2_itemId=1007

The questions is, is this normal? :confused:

http://www.images.atragon.org/main.p...g2_itemId=1011http://www.images.atragon.org/main.p...g2_itemId=1015

By this, I'm refering to the rust coloured areas visible on the fins of both the MCR220 and 420s, and on the end wall of the MCR420. I'm kind of concerned since I don't recall seeing any pics showing similar discolouration before, and I don't want to make a potentially expensive mistake by not taking action if I need to. (The flash makes it look slightly worse than it really is.)

Regarding the paint chip on the 220, I could touch it up myself, but I doubt it would be a perfect touchup, and it would probably bug me, when combined with the discolouration, I'm wondering if I need to think about an RMA.

Can anyone offer some insight?

Thank you in advance.

Paint chip is nothing could just be packaging handling.. just touch it up like you mentioned, As for the rust doesnt seem all that bad tbh, my 360gtx came like that.. just give it a big flush and see what the outcome is..

that's not rust, that's the color of the fins, they just weren't painted that throughly.

Copper doesn't rust, so I'm going to have to agree with Aphex_Tom_9 on the lack of paint. That may actually work out better as far as performance goes since the copper is exposed (and therefore has no insulator holding heat in), though it may oxidize over time.

As far as the chip goes, dunno if it's normal, but it looks like the whole paint on the radiator was a bit too thin. If you're concerned with touching it up, I'd say just tape off the fins and repaint it all.

Also, is the rad going to be in a location where either of the issues will be visible? If not I'd say to 'set it and forget it' as Ronco would say.

Oxidising or darkening of exposed copper usually is on surface only, it won't progress very deeply, affecting only looks, not thermal efficiency. Though looks may be very important for somebody aswell :)

Oxidized copper I can live with. I'm still trying to figure out tube routing and thus fittings required since I want to get a bit fancy and try to hide some of the tubing runs behind the motherboard tray and drive cage stack, I know I have the clearance to pull it off, but I've yet to figure out how to get the tubes through the side wall of the 5 1/4" bays without really ripping it up.

I've been putting some thought into possible layouts to minimize the amount of visible tubing, and think I've narrowed it down to 3 options, though I'm not sure which option is the best to go with.

Option 1: Res -> Pump -> 420 -> CPU -> GPU -> 220 -> Res
Option 2: Res -> Pump -> 220 -> 420 -> CPU -> GPU -> Res
Option 3: Res -> Pump -> 220 -> CPU -> GPU -> 420 -> Res
Option 4: Res -> Pump -> 420 -> 220 -> CPU -> GPU -> Res

http://www.images.atragon.org/main.p...g2_itemId=1028 http://www.images.atragon.org/main.p...g2_itemId=1033 http://www.images.atragon.org/main.p...g2_itemId=1037 http://www.images.atragon.org/main.p...g2_itemId=1041

In terms of loop layout, I think option 4 is the best option, however I am a little bit worried about the relatively tight confines of fitting the pump behind the res and how I would be able to slid it out to fill it. Then again, if I'm careful, I may be able to put enough slack in the line from the pump to the 420, and the return line to allow me to slide the res out.

Also, for those who noticed that the res is sticking out the front of the case, that's because the DD Monsoon is much shorter than the XSPC res that I used as a placeholder in sketchup.

I'd go for #1, as shortest/simpliest tubing routing. I don't get much why you like 4th, with going extra up-and-down without much extra need for that.
And hmm, shouldn't rad in lower compartment be turned with inlets in middle of case, so that tubing can be passed through holes for wire managment?
Also be careful with selecting tubing width. Check if selected tubing size OD (and it's fittings, if some of them will be placed there too) fits well behind motherboard tray and other areas, where you plan to route tubing.

#1 appears to be the best option and #4, problematic. Just my 2 cents.

There's just over 21mm of space between the raised lip of the motherboard tray and the side panel, the 3/8" ID 5/8" OD tubing I'm using will leave me with about 5mm of space to spare.

The reason why I like #4 is that it puts both rads between the pump and the CPU block.

However, I suppose that having either rad in the loop between the pump and the CPU block is just about as good, arguably better since having one rad before the pump would help cool down the water before it hits the pump, and you're correct that #1 does eliminate 2 extra up/down tubing runs.

As far as lower rad orientation goes, I can dry-fit it both ways and see which one looks like it will result in better tube management. Don't forget though, I need at least one of those wiring management holes free to pass the PSU wiring through. It also gives me ideas for drain/fill of the loop, I can throw a T on the low point of the run and get everything except the lower rad for draining.

I'm not sure if I have the space, but I might even be able to put the lower rad on standoffs, flip it upside down, and then be able to drain the whole loop at once from there.

For filling, if sliding the res out doesn't work out, I could put another T fitting on the top run and fill that way.

As an added bonus, if I use Q-blocks, the 4th port gives me a handy place to stick a temperature sensor to get water temperature data both before and after the rads.

TL;DR version: From your comments, #1 seems like the way to go. Also, fill/drain can be done /w T-lines at the top/bottom behind the back panel. And, if I go with Q-blocks instead of T-blocks, I have handy points to measure water temperature both before and after the rads.

Loop 1 or loop 2 seem like the best ones to choose, i'd go for loop 2 and add a sexy drain line :)

I'm not entirely sure that the drain fitting I'm looking at can really be called sexy. How about a sexy fillport instead? ;)

I'd appreciate it if you could look over my cart and let me know if there are any glaring omissions from what I'm planning on buying from Performance PCs.
http://www.images.atragon.org/main.p...g2_itemId=1045

The reasoning behind the fittings is as follows:
CPU block: 2 Bitspower compressions + 1 45 deg rotary
GPU: 2 Bitspower Compressions
MCR420: 2 Koolance Compressions
MCR220: 2 Koolance Compressions + 1 45 deg rotary
MCP35X: 2 Koolance Compressions
Res: 3 Koolance Compressions (1 inlet, 1 outlet, 1 fill line)
Drain fitting: 1 koolance compression, 1 temperature sensor, 1 male-male
Flow meter: other end of male-male, 1 koolance compression
Nozzle Body: 2 koolance compressions, 1 temperature sensor
Fillport: 1 Koolance Compression

Sensors will be connected (eventually?) to an Aquaero, I'm just waiting for the new one to drop.
Res will be a DD Monsson, once it releases.
Kill coil for obvious reasons

Filters are for case floor (the 140mm) to cover expanded hole for MCR220, and for case rear (the 120 as a 140 wouldn't fit) as I am strongly considering turning the exhaust fan around to maintain positive pressure.

Edit: Missed something... TIM. I'll be going with Shin-Etsu X23-7783D as while I'd like to go with Indigo Xtreme, I killed my tube of AS5 recently, so I need to buy more TIM to use on the GPU block anyways.

Just annoyingly busy with school. I've had almost no time to work on the project recently, which is annoying as I really want to get this up and running.

I've got my hands on the screws I'm going to be using for the radiators and fans

http://www.images.atragon.org/main.p...g2_itemId=1049

1 1/2" 6-32 flat-head socket cap screws for mounting radgrill -> case -> fans -> rad

1 1/4" 6-32 pan head socket cap screws for mounting fans -> bottom rad

3/8" 6-32 flat head socket cap screws for mounting radgrill -> case

I ordered them all from Fastenal, a Canadian equivalent to McMaster, though with higher prices (it being Canada and all), and slightly worse selection. 50 screws of each type cost me a total of $20, which I'm quite happy paying, so that worked out quite nicely.

The reason I went with flat head is because I want a very smooth look to the top and bottom of the case, and being able to countersink the heads will really help with achieving that.

Still to do: Nail down how much sleeving I need, finalize the order for fittings + connectors, get my hands on a reservoir, decide on which Aquaero 5 I want to order.

Oh yes, and assemble the whole thing. :)

And I also went and placed 2 of the 4 other orders I think I need to place...

Lots of assorted stuff (wires, connectors, fittings) from Performance PCs, and sleeving from MDPC.
http://www.images.atragon.org/main.p...g2_itemId=1053 http://www.images.atragon.org/main.p...g2_itemId=1057

Still left to order is the reservoir from DangerDen, and an Aquaero + temperature sensors + relay connection for hard shutoff from Aquacomputer.

One item that I need to decide on is whether I should go with an Aquaero 5 LT or XT. In terms of system control, either one is perfectly acceptible, while the XT has the advantages of having a remote control (I'm strongly considering dual-purposing this rig as a HTPC too), and a display, again useful for HTPC work.

(I'm sufficiently not a fan of the Pro's faceplate that I'm not even considering it.)

I'm just trying to figure out if that's worth 80 euros to me or not. At least I've got some time to decide.

BTW, think also about where/how case is gonna be placed. For example for me it will be on the floow with case front in table direction. If i'm sitting near table, i can reach buttons with hand or configure by software. If i'm in places where remote control might be used, IR remote sensor will be facing other way. Without usable remote it's much harder to justify purchase of more expensive XT for just different/extra buttons, if one knows that passive heatsink included in XT will be replaced with waterblock anyway. Though if one goes for looks only, that pricing difference might not be high enough to set back.

Thank you for that perspective Churchy, I suppose it's going to boil down to whether the remote will be useful or not. I need to think about that.

Well, colour me surprised, I got home this evening to find this waiting for me:
http://www.images.atragon.org/main.p...g2_itemId=1062http://www.images.atragon.org/main.p...g2_itemId=1067

That was some quick shipping from MDPC. Inside is (hopefully) more than enough sleeving for this build. Nils threw in some short lengths of red and white sleeving, which I'll try to find a use for being Canadian and all. :)
http://www.images.atragon.org/main.p...g2_itemId=1071

Atragon: well, seems that i somehow didn't notice optional IR-Booster, which probably should solve any reception problems because of case front direction (i don't see it listed among items on aquacomputer's shop, but saw it's pic in first page of AA5 thread @XS).

I came home today to find another package waiting for me, my order from Performance PCs.
http://www.images.atragon.org/main.p...g2_itemId=1075

I've almost got everything for the build now, just waiting on the Moonsoon res and Aquaero 5 to drop, and then I'll have bought everything for this build. Also, reading week is next week, so I will likely have time to start getting stuff put together. (I won't be able to finish the build then though due to aforementioned parts).

So it's been a while since I've last updated, school has been keeping me annoyingly busy, and I haven't made any physical progress.

However, I have been chewing on what I want to do for a top radgrill, and I've settled on getting one custom cut to my design since I want to integrate the fillport into the grill. Unfortunately for me, while I've decided on hexagons, I've also decided that I don't want to just tile the same size of hex over and over, and would much rather tile two different sizes of hex. However, I can't quite decide on which way to join them together. I'm leaning towards either option 1 or 3 of the below options, and would like your input.

http://www.images.atragon.org/main.p...g2_itemId=1080http://www.images.atragon.org/main.p...g2_itemId=1085http://www.images.atragon.org/main.p...g2_itemId=1089

Not a terribly exciting update, but I've finished the 3d models for both top and bottom radgrills, now to get a quote for having them laser/hydrojet cut and powdercoated/anodized.

Progress will, unfortunately, continue to be slow until the end of exams in mid April. :(

Ok, so after about 5 months (gotta love school followed by real life and a summer course for their ability to suck your time dry), I've gotten back to this. I had the radgrills made, and they turned out beautifully (No pics atm, will wait until painted). I've also cut the holes for mounting both of the rads in the case.

Unfortunately for me, I've hit a significant snag...
http://www.images.atragon.org/main.p...g2_itemId=1296

That's right, the fan mounting holes on both my MCR420 and MCR220 are too widely spaced. I literally cannot mount a fan to the 420, and it would take a lot of force to do so with the 220 (it isn't as badly off, instead of ~110mm hole spacing, it only has ~106.5mm hole spacing). I've opened an RMA with the vendor I bought them from, now to wait and see what they say.

In the meanwhile, I'm prepping the case and radgrills for painting.

Joy.
