Benching:Radiator/Fans???

[wibujo]

I spend most of my time benching CPU and was wondering what would be the BEST upgrade I could make to my RIG. I currently have 3 Feser 480 radiators with GT 1850's. I want to run ONE radiator just for cooling CPU. (My core temps currently hit 80c while benching which I'm not comfortable with). Should I get a different radiator for this ??? I was also looking at the new GT's - Which fan would help the most - GT3000/GT4250/GT5400??? Noise willnot be a problem as long as core temps are lower. I,ve all but given up on the Admiral. I don't think it's ever going to happen. Anyways, I'm trying to get my core temps down and was wondering if someone has any suggestions? Thanks wibujo

Hwlabs Gtx 360 or Gtx 480 with those 3000 or 4500 rpm scythe fans should be pretty insane i think :)
IIRC from Skinee's charts , the Gtx 360 has 1100 watts of heat dissipation with a 10 Deg Delta with 3000 rpm fans.
2x HWlabs Gtx 480's is pretty much what i have in mind for my bench :)

Can you give us a bit more info on what you are cooling?

Do you know your water temps at full load ?

Any idea on flowrate?

If you dont care about noise 8 of the most powerful fans you can find on one of your existing radiators will probably work fine.

Even one Feser 480 rad should be more then adequate for cooling even heavily overclocked and overvolted modern cpus with rather silent fans. I'd say that even 360 should suffice. As for GTs - no need to get those high speed ones. Common AP-15(1850) have better minimum rpm range then those high speed models (many of which are bad at downvolting/lesser rpms) and should be more then enough for job. With such rad you can easily keep fans at 1000-1100 and have both adequate cooling and silence. Especially because those feser rads are well optimised for silent fans.

Thanks for the quick reply, I currently don't have flow meters. I have temp sensors but they are not installed as of yet. I need help buying the correct flow meters though. My RIG is set up for 3 loops. One is idle because (new) reservioir has leak. Going to order new reservoir tomorrow. PM'd IandH about it but never got response. He may not have recieved it. OK - I run "FIRST LOOP" to cool my CrossFired 5970's - Even while benching these temps never go above 40c. "SECOND LOOP" Goes to CPU then goes through UD9 Full board EK waterblocks. THIRD LOOP is idle - I was thinking of using it just for the CPU. Here's my parts list. Thanks wibujo (off to work)

I'm guessing that if you bought his reservoir not from him directly but from some LC shop you'd be better off to get RMA via it. He can be also contacted by mail (http://www.ihacc.com/index/contactus.html). He was at vacation for some time, and also has stated previously that email is his preferred form of communication.

tbh 3x 480 feser rads are quite sufficient.. I honeslty doubt exchanging rads would yield better temps.. Wats your ambient temps like? For better performance you could try push/pull on each fan seeming as you have a benchstation and should have sufficient space, Even adding some tops on the pumps will result in overall temps..

[antiacid]

you know, for the money you sunk into water cooling your bench, you could've invested in a top of the line chiller or a small phase change unit. I'm sitting on a similar setup (except I run 2 pumps, not 6 lol) and 15 fans on my 3x mcr320 and I'm also stuck at 80-90 when I bench 4.7ghz and above.

I'd recommend looking that way, selling your excess watercooling gear (keep only what's useful for cooling the video cards) and invest in a phase change unit.

if you have enough space, maybe you can try Hexa radiator for 6 fans: http://www.frozencpu.com/products/12486/ex-rad-207/MagiCool_XTREME_Hexa_720_Radiator_MC-HEXA720.html

might aswell get a mora 2 ;)

Actually, I'd recommend that rad over any of the Mo-Ra's. It's a plain 2 pass rad from the looks of it and it looks like a balanced 12 tubes per pass.

Thanks for the input, I already ordered the IandH reservoir to replace the other. I may have reached the limitations of my CPU ??? I'm going to see if I can get my core temps 3c to 5c cooler with the third loop - I may just be spinning my wheels - I'll post back with results when I get it up and going. What about Flow Meters??? Here's a couple pic's of RIG - If I did something wrong could you help me correct it??? Thanks wibujo

Holy bejebus!!! :shock:

....:druel:

[Alexandr0s]

Are those four or six D5's? :eek:

[Martinm210]

Wow...that's impressive. Push/pull/shrouded triple quads with GT15s should be looking at darn near ambient water temps.

Air conditioning to lowere the ambient if you don't already have it would be your best improvment..not much more in WC to do except maybe indigo xtreme TIM.

Phase would be next...

[OldChap]

If noise is not a problem then try running Just push and 38mm Deltas these revision C's (http://www.xtremesystems.org/forums/showpost.php?p=4639883&postcount=253) Note the "compared to others tested" graphic. Of course if you could squeeze in push pull then all the better.

I've yet to see results from Fast GT's but availability is getting better as a couple of US outlets hold them now (I'm in UK but someone here will know which ones)

Like Martin says I would not expect to get much lower temps though ...how about an air conditioned box to put your rig in for benching?

Edit....Martin, I'd like to see numbers for any push pull setup on your anemometer :stick:

[Elmy]

Looks like 3 ... one for each loop...

edit ... i count 4 .... hummmm

[Martinm210]

Edit....Martin, I'd like to see numbers for any push pull setup on your anemometer :stick:

I did push vs push/push vs push/pull with the yates here:

While it's a bit apples/oranges (pull fan is slightly hidden/baffled by the radiator) it's all I can do really and it shows push/pull being better in CFM per dbA than one fan.:up:

[OldChap]

Somehow I missed this even though I watched the thread.... Interesting result ..a little quieter and max 40% more flow rate which is perhaps pertinent info for op

RE: Availability of fast gt's.... Performance PC's list them as do Frozen CPU

Yeah, push pull fans is pretty impressive, a fair amount more power and quieter as well, hard to complain about that.

I'll do some more of this later with the GT15 vapor sent with shrouds, etc...after I do some playing with pumps..:D

[Johnny87au]

wow thats a crazy ass setup, hektic much ?? You could fit a mora in there quite easily..

[wibujo]

I have 3 EK Dual tops with 6x D5's. I viewed threads in this forum for 6 months before I decided to get serious about building my first WCing RIG. I'm working on custom fan grills for the top, front, and side panels. I will have 4x 80mm fans on each side panel so I can maintain positive air pressure in case.
Those yate loons get pretty loud (on front panel - So I run them @ 1200rpm when I'm not benching). Heres a pic where you can see the pumps. Thanks wibujo

[Johnny87au]

Are you running all those gt's on a fan controller? And which PSU u using??

[wibujo]

Yes, I'm running each loop on Lamptron FC-5 v2 fan controller (4 total) and one for system fans. I have SilverStone ST-1500 PSU. Thought about getting another 600watt PSU to run all the pumps and fans on. I researched doing it but still a little confused about it. One person says to do it this way another person says it will burn up PSU. To much conflicting info on web for me to jump into it. Does anyone have any suggestions on flow meters ??? What brand and where would be the best place to install them ???

[Johnny87au]

hey buddy im sure your 1500 would be enough as your only running SLI, but i know for fact 4 pumps and 4 fan controllers is overkill hehe.. I use the aquero flow metre but been looking into getting one of these koolance ones http://www.koolance.com/water-cooling/default.php?cPath=109_70 , only herd good things about it..

[BrokenArrow]

Stick with the AC flowmeter. I have both and the FM-17 is a cheap toy in comparison.
