Zalman 9700NT and E6850 issues... please help

post #1 of 5
Thread Starter 
Hi all,

I've had my rig since just before christmas last year, yesterday was my first time OC-ing. A friend and I got it stable at 3.5Ghz at around 67C during Prime95. It's been dead quiet, almost to the point where you have to see the power LED to know it was on?

However! I noticed that my 9700 was still CRANKING when i stopped the test? I wasn't sure why but even on idle it sounds like it's running a LOT harder than it used to?? I've since clocked it back down to stock, but the fan STILL sounds noisy?? Also my idle temps are still from 38C to 45C even WITH the Zalman???

***?? Is this something I can fix??

Obviously the Zalman is trying to keep the CPU cool as the temp has risen a bit. The fan may stay spun up for longer due to the extra heat created by the OC. Do you have a target temperature setting in your bios for the CPU fan which may be set a little low now as you've OC'd the CPU? e.g The target temperature setting may be under the your actual CPU 38-45*C temp making the CPU fan spool up slightly earlier, and if the CPU temps aren't dropping below the target temp the fan may stay spooled up.

Hey..

Can you increase the airflow inside your case?
I'm just in the middle of encoding HD video and checked my temps. 50 for core 1 and 44 for core 2...

Well I forgot to crank up my case fans and by doing that the temps dropped to 45/41 respectively..


It can make some noise at times.. but very rarely here..

What soft of noise is it. If its a clicking noise check to see if any heatsink fins have been bent down and are touching the fan. Also check for dust buildups around the heatsink fins.

What were your temps before, did you check?
