Well, I got all my new cooling gear thru courtesy of DangerDen last week and spent a good few days getting it all fitted... it's by no means finished, and at the moment I don't think it's performing too well due to a partially rushed installation but hey-ho!

So, for the cooling we have:

DangerDen 3-1 CPU Block with 226w TEC
DangerDen Z Chipset Block (northbridge)
DangerDen R9700 GPU Block (no TEC yet)
DangerDen Clear Reservoir
Eheim 1250 Pump
Thermochill 3x120mm Radiator
3x YSTech Slimline fans (lack of case-space)
Sunbeam Cheap n Cheerful Fanbus
MeanWell S320-12 TEC PSU

System Specs:

Athlon XP2400+
Corsair XMS3500 512Mb
Epox 8RDA+ rev1.1
Sapphire Radeon 9700 Pro rev3 (vmodded)
Enermax 431w (still working fine after all these years)
2x Seagate Barracuda IV 80Gb

Chip tops out at 2.5Ghz no matter what cooling I use :(
Just with this rig it does it around 30 degrees cooler!

Currently at 2419Mhz on 1.82 vcore and CPU Temp is 8 degrees.

Flow is fairly knackered at the mo as you'll see from the pics but I just don't have time to sort it!

Pump > R9700 Pro > NB > CPU > Rad > Res > Pump


The top of the case has been tidied up somewhat since this pic tho...

Got probes... left hand is GPU, right hand is air comin thru the rad...
http://www.over-clock.co.uk/marci/2003rig/fullfrontal.jpg

Air coming thru rad at moment is 30.9 degrees, Radeon GPU is at 33.3 degress, CPU is at 8 degrees....

Ambient temp is 32 degrees as read from onboard sensor.

So... cooling up to scratch or not? Suggestions for improvement of current setup without forking out for a 2nd loop for GPU & NB...

mmm, looking very nice marci!
Bit heavy tho! Can't wait to see ya lugging that beast to the next LAN :D

About the same weight as a prommi (I'm guessing), but either way, wheels & a geargrip make for easy moving... just need to arrange some reinforced tables for it!

From my little calculations (need to build a proper model) you should have around -21 unloaded cold plate temp then going up something like this

w c
0 -21
20 -15
40 -8
60 -2
80 5
100 12
120 18
200 44

Which my excel tells me y = 0.3267x - 21.196, assuming a 26degree water temp. (my model doesnt use the temp wattage degredation curve hence the linear fit)

So you temps look pretty good, although your system could be improved since my single 172w tec performs almost exactly the same :) But thats DD blocks for ya. Check my thread.

Basically the conclusions ive reached with tecs, even using waterchiller is they cant handle a tbred with 2v thus im moving over to phase change on the cpu. (unless you use quad 172's or dual 220's needing a powerplant to run them)

How much diff does the TIM make? I'm using AS3 on the core itself and on both sides of the TEC as I had nowt else to hand... know AS3 doesn't particularly like cold temps... just needin a few pointers as to whether splitting flow off would improve temps to VGA etc etc etc... lol, the rig was literally thrown together!!

Haven't reached 2v yet... still on 1.85/1.9 ish... don't think 2v will make much diff with this cpu tho tbh... need to get me an XP2600+

Well comparing my block to a dd tec block is like comparing (in ordinary watercooling) direct die watercooling to a dd block. What difference do you think it would make ;)

Using tecs however id go cpu -> gpu -> northbridge and not mess about with Y's. Since the increase in water temps is like 0.1-0.2 degrees from input to output, so you really need to keep the flow rate up. You best investment imo cooling wise would be a 1060 pump. Or a 1040 and dual loop the rad on the 1040 with some flow restriction too, to cool the water more effectively.

I dunno.

TIM being Thermal Interface Material, as in Thermal Compound, not yer block... but out of curio what block have u got?

]JR[

The block itself is a TIM between the Core->AS->Coldplate->AS->Tec->AS->Block base->Water

Whereas my block, a few threads down in this forum has Core->AS->Coldplate->AS->Tec->Water

Much more effective :) The big problem is coldplate elimination and clamping your tec else you could have core->as->tec->water, P4's and Hammers will/could support that kinda setup with theyre heat spreaders.

yeah I know the block itself is classed as a TIM, but what I'm after is is AS3 ok to be using or would I get better results with a clear silicon based thermal compound....

Well i always use white heatsink slob for tec tim's AS goes nasty at cold temps. And the silver content doesnt inspire with 300+watts of power although it does have a rather high resistance.

cool, so first thang when I strip and rebuild it next week is ditch AS3 then, sort out the block order (CPU to GPU to NB rather than GPU to NB to CPU), remove all the elbows and find a better way to sort that out...

and then find a 1040-1060 pump instead of the 1250...

A 1040 is smaller than a 1250 and a 1060 is lots bigger, all available from reefkeeper.co.uk or aquatics-online.co.uk

Although a 1060 will set you back £60ish... Its a monster.

EDIT: apparently a 1060 is now called a 1260 instead.

Just a quick piccy update... finished modding up the case now!

Ta d00d! While yer about, a quick Q.... I suffer from TEC-Poppage!! :(

Not too sure what happened.... here goes...

Stripped rig down before LAN (Thursday night last week to be precise) to do the windows etc, which took flippin ages.... (Window cutting itself courtesy of Souljacker, Stevie & Deathwalker as I can't do power tools nemore since I got stabbed thru muscle in my right arm last year... if I try it nowadays you get lines wobblier than a wobbly thing on wobble-pills)

At the same time I thought I'd be crafty and get some load off my PC PSU. Sunbeam Rheostat in the front got hooked up to TEC PSU instead of PC PSU, seeing all fans need is 12v. Here's where I possibly went wrong *blush*

I then hooked up to Ch1 3x120mm fans, Ch2 3x80mm Panaflos, Ch3, 2x 80mm Panaflos, Ch4 1x92mm Panaflo 2x 80mm Cathode Fans 2x CBKII58 60mm Fans (offf globalwin heatsinks).

Silly me forgot to add up the ampage and wattage of all this lot, but figured it'd keep on going thru the LAN (which it did).

Powered on rig last night when I got in, all was fine. Did what I had to do, shut it down. Came back to it later & powered up and CPU temp wasn't dropping. Examined TEC PSU, and where the + wire for the TEC meets PSU (screw-terminal - meanwell psu) the plastic that separates each terminal looks a bit cooked, and the + wire up where it connects looks as tho shielding has melted... Everything else is fine...

So, was this caused by too many fans on PSU? Or dodgy TEC? Or wire not being rated high enuff?? Help most appreciated as need to fit new TEC tonight, and if fans were cause then need to get em shifted (well, will probably shift em ANYways, but.... y'know, it'd be nice to get confirmation!)

Never mind... original TEC is fine... not too sure what happened to be honest, but to be safe all fans are now runnin off the PC PSU again....

Sounds like too thin wires really, or wiring up one fan backwards. Since that psu could power like a 100 or so fans :)

Tecs are fairly robust the usual failure mode is wires snapping off from where they connect to the tec.

The full modded case / lighting / PSUs and cooling system has just sold for £850.00 UK... with Matrix Orbital, Mobo and CPU left in to save new owner having to condensation proof own board etc!!

Guess it's time for phase change now... *shrugs*
