PNY GTX 580 Liquid Cooled GPU and CPU
Temperatures and Noise
We normally test graphics card temperatures by firing up FurMark and let it run for awhile until the temperatures level out. FurMark pushes GPU thermal loads extremely high, and can be considered a worst-case scenario. However, with the added CPU cooling capability here, it is critical to also test the processor’s temperatures as well. In order to do this, we will again examine a "worse case" situation by running both Prime95 and FurMark concurrently to maximize the heat output for the radiator. We then let the system run for 30 minutes, which is sufficient time to allow for the entire system to fully heat up and level off.
Below are the "worst case" GPU temperature results:
Hear that sound? That was my jaw hitting the floor. The GTX 580 XLR8 Liquid Cooled posts results that are 40°C cooler than the reference air cooler. That’s nothing short of outstanding. Keep in mind, this is WITH the CPU running at full tilt on Prime95 as well. And with a Delta of only 13°C, the load temps aren’t much higher than idle, certainly nothing like the 49°C difference on the reference card.
Now let’s take a look at the CPU temperatures:
Wow. The PNY GTX 580 Liquid Cooled manages to beat the vaunted Noctua NH-D14 and claim the top spot for CPU cooling. Remember, this is with FurMark running on the GPU full tilt as well, so the results would be even better with only the CPU loaded. This is quite a shockingly pleasant surprise, to say the least.
In terms of noise, the pump isn’t terribly loud but the fans are rather noisy when running full tilt. The graphics card fan hardly ramps up, so it stays quiet. But the fans produce a higher-pitched sound signature, and are more audible that we’re used to for an internal case setup. Of course, you could substitute the fan(s) with something quieter, but still has a high back pressure, and we’ve had great success with certain Scythe and Noctua fans that would do the trick for an additional cost on your own. If you’re not particularly concerned about noise, and are usually busy fragging with the volume up, then you won’t have an issue with the included fan/pump setup.
