Phenom II 955 BE Stock fan Spinning fast just before shutdown

post #1 of 6
Thread Starter 
hello guys!!

i am facing a unique problem with my stock cpu fan

many a time when i shutdown/standby my system the cpu fan suddenly throttles to full speed and then shutsdown
its just like when you blip the throttle of a bike

it happens even when the temps are normal

my temps
idle-38 load-54

it is totally random

the system was oced to 3.4 via asus cpu levelup, but it happens even after disabling it
-have flashed the bios to latest version
-cleared cmos


kindly help

Problem?
My 9800GT goes to 100% fan then to 35% after startup So does my 460.
Same thing with my V8 cooler.

No idea why it would do it on shut down, but I wouldn't be concerned anyway.

Dunno, the fan on my 955 starts off at 100% when I start up. Slows back to normal on the windows loading screen for me. Never really bothered me, but I could see how noise like that could annoy some, even though it only lasts a few seconds.

I think its just testing the CPU fan, because it also happens to me, sometimes on startup sometimes on shutdown. All i no is that its still working.
