Test System & Test Results
TweakTown uses a different method for testing CPU heatsinks which allows for an even playing field across all product tests. We feel that by using the same ambient temperature and strict lab-like testing procedures we are able to accurately compare one product to another. More information on our testing procedure can be found in the T.E.C.C. article here.
At idle the 920 didn't take top honors on the overall listing, but they sure took the number one position on these all-in-one coolers.
Load testing with essentially extreme mode running in the TECC box, I was really surprised to see just how well this cooler ranked and how well it took the abuse. For the earlier screen shots of the software I was running a 65nm E6400 with 1.65V going through the processor. I wasn't able to break out of the nineties even giving that old hot tech a lot of volts.
Don't let this rating fool you on the quiet capabilities of the 920. In silent mode with the software, the unit is exactly that, silent! - To keep things fair, I gave these fans the same 7.5V I give all the other fans on this list for a more even playing field for the results.
In extreme mode, with 12V going through both fans, the 920 takes top honors in being the loudest pair of fans I have tested. Keep in mind that with the included software, this level will likely not be the normal level of operation, more like when you are benching or gaming for many hours, and even then you can still make the fans not run at 2400 RPM.
