I just got my GA-965P-S3 system up and running and noticed that my CPU fan would run for about 1 minute or so then stop and then start again. I also noticed that when running, it only runs about 800 RPM. My CPU temps are ok on boot up at around 32C but after about 15 minutes it's up to around 50 C at idle. I tried using the Easy Tune 5 to set the fans but that button is greyed out. I even tried setting the Bios but with no luck. I'm wondering though if the Fan itself may be bad.

I also have the same problem, except the heatsink fan stops right after startup for like 1 second instead of 1 minute, and starts again, and when I get to windows its at about 1000rpm. This doesnt happen when I restart though. Im also getting the low toned buzz at startup(do you get this?). When I run I-Cool, after some time, the heatsink fan stops, and doesnt come on until I turn I-Cool off. Is this a problem with my heatsink or a problem with I-Cool/ Easy Tune 5?

Ok, got my new Zalman 7900 and installed it and the fan just sat there and rocked back and forth while the CPU temps went up slowly. I finally went into the Bios and disabled the Fan Speed Control Method and now the fan turns at 2800 RPM all the time and the CPU stays at around 21C at idle. I have tried different settings both in Bios, I-Cool, and EasyTune 5 and no matter what setting I try, the fan slows down to 300 RPM and of course the CPU temps go up. Could it be that I need to update my Bios? Right now it is F5. BTW, if you forgot, I have the Gigabyte GA-965P-S3 MB.

Ah great, so apparantly its the the mobo's problem and not the heatsink I guess. The latest BIOS is F6, but even with that, my fan has the 10-15 second no activity problem at startup.

I also wonder why the 'Smart Fan' option in EasyTune 5 is greyed out. Seems like anything that has to do with fan control does not work.

That will be disabled if you disable the fan control in the bios. Also i have the Zalman 9500 on my E6400 and that came with a dial to control the RPM. I have it running at 2400 RPMS and it keeps my CPU (coretemp) ~45 idle with being overclocked to 2.65GHZ. Also make sure you are measuring your temperatures with CoreTemp or TAT.

Hmmm, I guess the 9700 does not have a dial. Yes, I am monitoring the core temp with TAT.

As far as disabling the fan control, that's the only way I can get the fan to turn. If I put it on auto, the fan will not run at all even if the core temp goes up to 50C.

Ok, I finally found the answer and the fan now works. In the Bios setup, you have to have the fan control enabled of course but you have to set the Fan Speed Control Method to PWM. Now the fan speeds up when needed.
