Hello, I would like to cool my single GTX480 GPU using a 240 rad since it is reaching 90C+ on stock speeds with the stock cooler. Id like to know which rad would be a good choice for a cheap price

I have 2000RPM/90CFM coolermaster fans

Swiftech MCR220. 2000rpm fans will be overkill.

Good radiators are the GTX series by HWLabs.
no

Yes.



Assuming that the 120 version of that rad can dissipate 1/3 of the heat the 360 can, at a 10C delta with 2.8k RPM, a 120 rad can dissipate roughly 370w of power. The GTX 480 is less than that, so the water-air delta of 6-7C will be achieved. You could improve temperatures even more if you used push-pull. Also, considering GPUs aren't as heat sensitive as CPUs, you could reduce the fan RPMs and still have decent performance.

i refuse to believe that.......an H50 can barely cool an i7 and they're saying that a single 120 can cool a gpu which puts out twice the amount of heat?

1. H50 radiator is smaller than a GTX radiator
2. H50 doesn't use 2800 RPM fans. Look at the piss poor performance with 1000rpm fans. If you'd actually like your GTX 480 to be quieter than stock, you need a 240 rad.

Yes, I'm cooling 3 gtx 480s and an i7 on a 240 and 360 rad with 1k rpm fans. Full load on both the CPU and all gpus is under 60c

Thanks, the MCR220 seems like a good value. Are there any good universal GPU blocks? because Im not sure how long I will keep my GTX480

Swiftech MCW80 + GTX 4 hold down kit + GTX 4 unisink (cools ram and vrm)

the weak link in 99.9% of liquid cooling systems is the waterblock.. well more accurately anything in between the actual chip and the water. (solder, heatspreader, TIM, waterblock, in that order)

furthermore, as has been stated, a GTX radiator is in a different league than the H50 rad. (double row VS single row, and numerous optimizations on the GTX. iirc the H50 rad is also aluminum instead of copper)
