Just an FYI in case someone else runs into this. I ended up finding out this was a combination of a design flaw with the stock Intel cooler and ASUS poor Linux support. In the end I found a 3rd party heatsink and fan which actually followed the PWM specifications i.e. with all the bios fan controls ...

I'm an engineer with 20+ years of Linux experience. I tried the Linux fan support first. It was a dead end with this board. I've tried several drivers and even decompiled the DSDT to see if triggering some of the Windows specific things would make it work. It didn't. The autodetected driver exposes ...

I've replaced the thermal paste so cooling is quite good when the fans are working properly. In Linux with an idle CPU I get CPU temperatures between 33C and 40C. The bios HW monitor shows similar temperatures. In Windows in CPUID HWMonitor I get around 40C for CPUTIN. The difference is under load. ...

When connected to PWN_FAN the CPU fan rpms were in same i.e. not full speed. They ran at ~900 rpms.... How PWM works is that a full 12V is supplied and the fourth cable carries a control signal that instructs the integrated circuit built into the fan to pulse this voltage to the motor. In the absen...

Are you saying that either disabling CPU Q-Fan Control, or setting it to "Turbo", doesn't change at all the stock cooler fan speed? BTW, somehow it sounds rather odd that you ask here how to make your rig as loud as possible. I am saying on this board changing to Turbo does nothing unless you are r...

From what I remember of these boards there was a header marked PWR_FAN. This was a 3 pin header designed as its name suggests to monitor the speed of a power supply fan (there were PSUs around at the time which had an external lead which you could plug into this header). However in addition the PWR...

Hi, if you simply remove the 4th, PWM control wire from the fan plug the fan will run at full speed. It's usually green or blue coloured... I was really hopeful this was this simple but it doesn't seem to be. I took my 4 pin CPU fan and put on my three pin chassis 2 fan header being careful to ensu...

I have an Asus P6T Deluxe V2 with an Intel i7 920 CPU. Unfortunately this motherboard is quite braindead if you aren't running Windows. In theory it controls the CPU fan using PWM. Instead of running the fan on auto or at full speed before Windows loads the board runs it at a low idle speed. Great f...
