[RESOLVED] Noisey CPU fan

[MPTech]

So I finished installing a new mobo (asus p5qpl-am) for my brother-in-law. Works great and runs like a champ, no problems, but I noticed it was too loud for my taste (don't know what it sounded like before) and my brother-in-law asked me if the fan is supposed to run all of the time and why it's so loud now.

I didn't change any of the BIOS settings, in fact, didn't even go into the BIOS other than to set them as "default". Reviewing the manual I found this:

2.5.5 Hardware Monitor
CPU Temperature [xxxºC/xxxºF] or [Ignored]
MB Temperature [xxxºC/xxxºF] or [Ignored]
The onboard hardware monitor automatically detects and displays the motherboard and CPU temperatures. Select Ignored if you do not wish to display the detected temperatures.
CPU Fan Speed [xxxxRPM] or [Ignored]
The onboard hardware monitor automatically detects and displays the CPU fan speed in rotations per minute (RPM). If the fan is not connected to the motherboard, the field shows N/A. Select Ignored if you do not wish to display the detected speed.
CPU Q-Fan Control [Disabled]
Allows you to enable or disable the Q-Fan control. Configuration options: [Disabled] [Enabled]
VCORE Voltage, 3.3V Voltage, 5V Voltage, 12V Voltage [xxxV] or [Ignored]
The onboard hardware monitor automatically detects the voltage output through the onboard voltage regulators.

what is the CPU Q-Fan? (Quite?) I haven't looked yet, should this be enabled or disabled?
Is this the problem?

Q-fan is basically PWM where it will control the speed of the fan depending on the load. If you have it disabled, I'm guessing the fan is running at full speed.

Yes indeedy, if you enable Q-fan it should quieten things right down. Hopefully they have now sorted out the situation where it used to cause the fan failure alarm to go off, if they haven't fixed that, then you need to disable CPU fan monitoring.

Stopped by my brother-in-law's this evening, rebooted his PC into the BIOS, "enabled" the CPU Q-Fan Control and......................
quite as a church mouse!

THANKS guys

You can do it yourself. Go to Thread Tools - Mark Thread Resolved. The toolbar is right above your original post.
