Test System~
All temperatures are with a closed case. My case has not been optimized for airflow so a "cleaner" interior could produce better results. Idle temperatures were read 15 minutes after boot, with no backgrounds apps running. Load temperatures were read after running Folding At Home 2.0 for 30 minutes. Over clocking was done with by multiplier only, FSB was constant at 133. Arctic Silver II was used in all tests.
I substituted a lower RPM/CFM fan from an FOP-32 hetsink and got readings that were approximately 1-2 degrees higher at stock speeds and 5-6 degrees higher when overclocked. I am getting 44C at 1.33 MHZ as I write this(with FOH running). This is an excellent heastink. It is well manufactured, compact,and has a sensible fan retention system. Like many others I prefer the six point attachment system over this two point system because I feel it is more stable and you can still use the motherboard if you break off one of the middle tabs. This heatsink scaled very well with different fans, unlike others I have had which only worked well with a 6800 rpm fan. Keep in mind that these test were run on the older TBird cores - which approach their limits as they get to 1.4+ MHZ - and which run as much as 15-20% hotter than the XP cores according to published reports. The SK6 was able to handle these chips easily, with high performance and mid-performance fans. I would love to see what this heatsink would do on a CPU that had a heat spreader. If you're like me and want to get the most out of your CPU, you can't go wrong with the SK6!
Thanks again to our good friends at CrazyPC for making this fine product available to review. Direct Link to the $24.95 SK6 and there you can select from various fan options.
