I've replaced the stock graphics card cooler with the #n3rdware alternative. The idle temp with the stock cooler and with the system case open was about 55 C. It looks like the new setup with the case closed has an idle temp of 63 C. I can probably improve on that with a shroud, but let's see how it runs under load first.
Also, I probably should have run the new cooler with the case open to have less variables changing for benchmarks. I may still do that before messing with printing shrouds.
