I was mistaken about the VRM temp. It looks like the current version of GPU-Z reports it. It wasn't there with older versions. So there are 3 GPU die sensors and 1 VRM sensor. Anyway it looks like my lopped off baseplate keeps the VRMs quite cool even in Furmark. I saw upper 60s temps.doveman wrote:It's a shame your card doesn't show VRM temps, as that seems to be the most problematic part of the card to keep cool. The GPU temps seem OK, but without testing with the card overclocked and Powertuned, it's impossible to know whether the cooler is up to the task.
I'll certainly not try the S1 on my 6950 though!
There is no doubt that the TRad2 is much more capable than the S1. With the two included fans at only 7v (maybe 1000RPM) it blows away every S1 configuration I tried. An overclocked 6970 would almost certainly need the fans at 12v though because I think that may be a ~50W power increase. I do like how the TRad2 is slimmer than the S1 and yet outperforms it! But it does cost $20 more and is getting hard to find. BTW, not all of them come with the Thermalright fans.
