Well.. colour me impressed! After my first 920 was DOA I was toying with the idea of a 620 with x2 Scythe gentle typhoons. In the end I decided just to go for the 920.
Since I had installed one previously and found it to be a complete PITA when still mounted in the case I took my motherboard out and installed it that way. Far easier and I got a much better install without the TIM getting messed up. First off I tried plugging the fans into my fan controller (30w per channel) unfortunately even though the controller can control fans down to 0rpm it couldn’t keep them at a low enough RPM for them to be silent. At first I though this must just be how they sounded. Anyway I then tried them with the software and they really are silent!
I tried a quick blast of intel burn and 4.5ghz and it didn’t pass 55C!! Very happy with that.
I then bumped the voltage and set it to 4.8ghz (first try at that speed as well). It passed 10 runs on low setting of intel burn with the temps being fairly similar. Highest being 60C I think, (my room is cold and the case has great airflow). I then did a 3D Mark 06 run and got 30400 points which I was happy with! Finally I set Intel burn test to max and set it to run.. it BSOD 101. So guessing slightly more vcore is needed. Also im running 1.65 ram at 1.55 on stock speeds and timing so may bump that up to rule it out. But all in all very very impressed. Max setting is nuts but its not really needed for everyday use. I set custom profile and had played a few games and it never got that audible but really kept temps in check.
So next up try to get 4.8ghz stable and then go for the big 5ghz
