Overheating?

Items in question: Asus M3A76-CM (BIOS fully updated) mobo, a Zalman CNPS9500A fan mounted on an AMD Phenom II X2 550 Black Edition proc.


My problem is high fan noise (possibly heating issues as well?). The machine is used mainly for gaming (Aion). It was previously using the stock processor fan, but was replaced because it sounds like a small lawnmower, but is now using the Zalman fan (described above) to hopefully provide better cooling and much lower fan noise. But instead the fan is going full speed (2600 rpm) all the time (idling or full load). I went to the Asus site and installed PC Probe II to see CPU temps and it's showing 42C idle (2650 rpm), while the chassis fan speed is showing 1950 rpm. I'm a little bit of a nub when it comes to voltages, so I don't know if it could be something regarding that. Thoughts?

Whats the temp while gaming? Current Bios?

BIOS is at the latest version (1001). The CPU temp which I've just checked (after about an hour of gaming) is around 49C, and of course the fan is still going full bore.
 
I trust you've eliminated the obvious?:

Checked the heatsink is properly seated and has enough thermal paste applied properly.
Check you've plugged the fan into the correct socket on the mobo.

Room temp is what?

Do you have cool 'n' quiet enabled?

Room temp is at 77F (25C). And yes, cool 'n' quite is enabled.

Everything looks installed properly. The fan is plugged into the correct socket, however the mobo has a 4-pin connecter and the fan has a 3-pin connecter. It fits in the socket fine, but still makes me wonder.

What 3 pins have you connected the fan to? It should be 1, 2 & 3.
I'm not a guru on this but I think that's why your fan is running full speed, since the mobo socket is PWM.

Happy to be corrected by any gurus that want to step forward :)
 
Here's an example of what I mean when I say it's only connecting to 3 pins. Note this is not my image, but it was asking the same question in this thread (offsite).

Use Core Temp or Real Temp and report results for idle temps and prime95 full load tests.
