Testing

     Testing was done by allowing the computer to boot and idle for 30 minutes.  During the 30 minutes the computer was not allowed to go into sleep mode or screensaver mode.  For the load temp, two instances of SP2004 was ran, maxing out each core of the CPU.  The test system is as follows.

Hardware	Model
Motherboard:	abit AW9D-Max
CPU	Intel C2D E6600 (L629F)
Video Card	eVGA 8800GTS 320
Storage	Seagate 400GB SATA
Optical	Lite-On 16X DVD+/-RW with Lightscribe
Memory	Patriot PC2-9600ELK
Cooling	CM Sphere AeroCool Dominator Intel Retail

AeroCool Dominator	37C	51C
Intel Retail Heatsink	40C	61C
Overclocked (3.2GHz, 1.325v)
CM Sphere	WNR	WNR
AeroCool Dominator	38C	55C
Intel Retail Heatsink	WNR	WNR

*WNR=Would Not Run 

Conclusion

     The results of the tests speak for themselves.  The CM Sphere just couldn't hang with the Dominator and was only marginally better than the retail heatsink.  I just don't think the fan is moving fast enough to move the massive amounts of heat that my CPU is producing.  If you are looking for something that looks nice and is silent, this is the heatsink for you.  If you plan on overclocking, then you would be better off spending your money on something else.  Not Recommended for overclocking.
