Glas, that Zalman will spin at a top speed of about 2600rpm and is pretty quite at top speed. To unleash it go into the BIOS and navigate to PC Health. Toward the bottom of the page you should see something like CPU Smart Fan Control. Disable it then hit F10 to save and exit. The extra 1200rpm should make a noticable difference. Let me know
@ Donald
I'll help anyway I can, just let me know what you need.
BTW, I'm sure you know this but I feel it should be stated anyway. Lapping a processor will void the warranty.
