need urgent help with fan speed on 965be - fixed

[Volkan^]

guys, recently ive been noticing my cpu temps are just not what they should be.
ive read elsewhere that the stock fan can run up to 5000rpm? but i can only get mine to work at 3500 max with speedfan setting at 100%
what gives? what the hell do i need to do to get it to run at 5k rpm? when playing battlefield 3 im hitting temps of 67c which is WAY HIGH for this cpu as far as im aware.

please help me solve this :X

*edit*
also, i notice speed fan only detects two fans? ive got like 5 including the cpu fan. is there a way to route more power to my case fans so they run faster? this is driving me nuts.

First is the heatsink dusty? if it is clean it, are all the exhaust fans clear?

heya mate
I did clean it like 3 maybe 4 months ago, ill give it another hoover as im sure its dusty in there. but any ideas on this fan issue?
enabled 1 fan and its been running at about 3700rpm now and i saw it go to 4k at 62c i really want it to just run at 5k until i can get a zalman or something similar. annoying thing is im in istanbul at the moment so I donno any good retailer s of this kind of stuff and you can never really be sure if somethings real or fake when you go to an independent shop ;/

What MB are you using?

i also noticed if i limit bf3 to using just 2 cores it decreases the temp from about 64-61 but thats onl with cores 1+2 or 1+4 if its 1+3 temp stays the same....
whats up with that?

I would give it a clean first, are you using pc probe to measure the temp? so how long you in Istanbul for?

fixed it reapplying thermal paste did the trick
im in Istanbul for a while I guess. no time on it. here to make music and absorb new sounds. if I stay here for a year or two thinking of going to Germany too
