I recently bought a Phenom II x3 720BE proc and a Biostar TA790GX 128M mobo.
After the installation, I found out that the proc fan is getting noisy.
so I checked, and it is running at 5000RPM with Sys temp at 41C and CPU temp at 38C
My questions are :
1) is it supposed to be normal? i mean for a pII proc to run at 5000 RPM at those temp.
2) if this is normal, how am i going to solve it =)
do i need a new HST fan? any recommendation?

p/s: another new discovery, the fan turns quiet when aircond is switched on. the fan speed drops to around 3000 rpm.
Thanks for ur help !

My 7750BE fan is running at full speed also.
Your fan is running according to the pc temp

just feel a bit strange about it...since my old proc X2 3800+ only runs at 3000rpm with the same temp

ue cool n quiet

you can change your speed settings at the bios. by default, it will go to 100% above 40C, well, mine does before i changed it anyway. your bios has different settings based on your proc. phenom ii heats up faster than a x2.

my cm 12cm fans juz run on 1500++ rpm only..
possible to force it to run faster??

no way force a fan to run faster.
TS: use and enable Cool n Quiet. the fan will be slower because of the PWM. when temp is high, turn faster to cool it down, when temp is loww, turn slower. Note that if u overclock it will also run hotter. if the problem still occur, disable ACC in bios and enable cool n quiet. Install the amd cool n quiet driver if u r using xp or older.

i disable the Fan control in the bios d.. but the fan juz run about 1150+/-zz

ts wanna to unlocked it is it???
successful?

so now already can control the fan speed?
why not just grab 3rd party fan controller.
easy can set what ever speed you want

i own a phenom x3 8450, and guess wat last time it spin like 5k idle and when load it goes up to maybe 6k...and i chg into 3rd party cooler and nvr regret since then

may i know what kind of casing u are using?
cause some casing got bad airflow while some casing got superb airflow

im closing this thread.
TS, i think your question has already been answered

if there is anything, PM me
