Thermalright for your vid card
Coming from Thermalright, I fully expected a good performance from the V1. But I have to be honest, and the temperatures posted by the V1 made me shake my head in amazement. I expected a close race between it and the Arctic Cooling NV5, but in fact it was no contest.
From a noise perspective, it seems that Thermalright was very conservative with the noise figures stated for the 24cfm fan. Although rated at a not-exactly-whisper-quiet 31dBA, there was really no discernable difference in noise between the V1 and the NV5, which bodes well for those considering the V1 for a near-silent system
