My Happy Experience with Thermalright AX-7... I just wanted to let anyone interested in a good CPU cooler know about the Thermalright AX-7. I just installed that puppy a few hours ago (Thursday, 4/11) and it does a really good job.
My pc is a T-Bird 1.2gHz/200 mHz fsb OC'd to 1.4gHz/266mHz fsb, vcore at 1.80v, Asus A7V133, bios at 1008. Last year, I started with a PAL6035/YS Tech fan combo (little brother and precursor to the PAL8045), and found that anytime I ran at 100% cpu utilization I quickly (within about 10 minutes) got temps beyond 56°C, and then a BSOD (running WinXP Pro).
The next HS/Fan I tried was the Thermalright SK-6 with the Black Delta 60mm 6800rpm screamer, and Arctic Silver 2. Using this combo my temps improved to around 52°C at 100% cpu output (with the temp difference between mobo temp -- 26°C -- and cpu temp -- 52°C -- of about 26°C). Unfortunately, I couldn't put up with the "hair drier/jet engine" whine, so I replaced the Delta fan with an 80mm Sunon 2950rpm/39cfm and an 80mm-->60mm adapter. Again, Arctic Silver 2.
With this setup, I got a difference between mobo and cpu temps of around 29°C (for example, mobo at 25°C, CPU at 54°C) at 100% cpu output.
Still not good enough, so....
Thermalright AX-7 with 80mm Sunon 3900rpm/50cfm fan!
Running within a difference of 20°C between mobo and CPU (CPU at 100% utilization, mobo at 28°C and CPU at 48°C). Used Arctic Siver 3 this time, too. I expect the temps to drop a little more after a day or two of "run-in" of the Arctic Silver. At idle, the difference between mobo temp and CPU temp is 15°C (mobo at 26°C and CPU at 41°C).
Noise is very tolerable, really no louder than the 2900rpm Sunon with funnel... and a HECK of a lot more quiet than the Black Delta.
If anybody wants an SK-6/Black Delta screamer, let me know! PS: I lapped the SK-6, so you wouldn't need to do much more than touch it up to restore to better than "as new" surface.
This AX-7 is the best cooler I've personally seen... at a reasonable noise level... without going to water cooled.
Keep cool,
