HardwareLabs Black Ice GTX m92

post #1 of 4
Thread Starter 
I'm thinking of putting a Geforce Titan into my micro-ATX case. I'd like to provide decent cooling for it (not a stock cooler), but due to the limited space it may be hard to find room for a big heatsink + fan. I want proper cooling for vid-rams and VRMs too. With these considerations, water-cooling the Titan seems to be a plausible option.

But my case allows just one 92mm radiator, and I was able to find one such product, Hardware Labs Black Ice GTX m92:

According to an old posting,

http://hardforum.com/showthread.php?t=1510538

This radiator can handle up to 200W of heat, which is not enough for a Titan whose TDP is announced to be 250W. But then another old posting,

http://www.xtremesystems.org/forums/showthread.php?225268-Testing-the-HW-Labs-Micro-184-GTX-Rad

tells that GTX m184 radiator with 400W heat-dissipation can easily cool QX9650 CPU (130W) + N/B and S/B chipsets + GTX 295 GPU (289W) even under the full load.

So if m184 can handle more than 420W from a big CPU and an even bigger GPU, can m92 be enough to cool just one GPU of 250W TDP?

If it's not enough, is there a better 92mm radiator that can do the job? Or any better graphic card cooling solution for a small case?

Any comment/advice from a real experience with m92, or an educated guess from expertise would be appreciated.

Thanks in advance!

You might be better off investing in a new case, and getting into watercooling in the future.
That radiator CAN cool the titan, but not very well. There is a chance stock cooling could actually cool it more effectively.

A single 92mm radiator cooling 200 watts? I don't think so! At least not practically. A Triple 120mm radiator would barely pull that off On a side note, TDP != heat load (!= means does not equal)

The thing you need to consider here is delta temperature, which is the temperature of the liquid in your loop vs the ambient air, in this situation. The higher the delta temps, the more watts of heat your radiator can can cool. With a 10Celsius deltaT Martin had about 180 watts at 1400RPM fans, and 240watts at 1800RPM, and that was with a triple 120mm radiator...

So now imagine how hot the liquid in your loop would be for a single 92mm radiator to be able to cool 250watts? At the point air cooling will most likely outperform it. Were I you I'd invest in a nicer case, as ALMOSTunseen had said.

Thanks for sharing your expertise. As you pointed out, I didn't know what numbers to compare. In my 3rd link for the b@llz0r's system, 130W of QX9650 is TDP (thermal design power), which refers to, according to Wikipedia, the maximum amount of power the cooling system in a computer is required to dissipate. Also, 289W of GTX 295 is just the maximum power this GPU would need. So in b@llz0r's system, (130 + 289)W is not the amount of heat m184 dissipates. What is worse, b@llz0r's "full load" seems to push only CPU, rendering his test incomplete.

Martin's test is nice. By naively comparing the ares of GTX360 and m92 (as they have the same thickness), I would guess m92 has about 1/5 of the cooling power of GTX360. Then even in the best case case scenario, m92 can only dissipate less than 60W with Delta T = 10C. Since 250W of the Titan is again the maximum required power, not heat dissipation, there's no way of telling if 60W dissipation would be enough, though...
