Asus P5KPL-VM Q-Fan

andrewdodd13 · 10 Jun 2009 at 15:47

I got my Titan Fenrir this morning, got it installed (it just fits in the case), and went about setting up fan control for it.

Without Q-Fan on in the BIOS it runs at 2.2k rpm solidly, and is very loud. With Q-Fan on in the BIOS it runs at 1.0k rpm soliday, and is very quiet. It's supposed to speed the fan up when the CPU is under heavy load, but it doesn't.

I've set Q-Fan at both the Optimal and Performance levels, neither appear to do anything.

SpeedFan doesn't appear to work. It should be noted that under 100% load the CPU only rises to 51oC, however when I was trying it with the Intel stock HSF last night it was reaching 70oC and the fan still wouldn't spin up.

Any ideas?

Hmmm not sure, I've used that board but didn't have any issues like this? Have you connected the Titan Fenrir fan with a 3-pin or 4-pin connection and are you sure its the CPU fan-header?

Having said that you stated you used the Intel 4-Pin PWM fan with the same result? :confused:

The Q-Fan feature doesn't spin-up the fan until it deems the CPU is too hot, I'm not sure if the Motherboard/BIOS takes these temp readings from the CPU socket or the on-chip DTS?

I would imagine that if your using a 4-pin PWM controlled fan connected to the CPU fan header with Q-Fan enabled in the BIOS the fan would kick in somewhere around 55°C load . . .

It is the 4 pin cable I'm using - and there's only 1 4 pin socket on my board, so definitely the CPU one.

If it kicks in based on temperature then I can't actually test it, the highest I can get is 55 and that's with Linpack.

Do you have asus ai suite installed? I use this on my p5q dlx to fine tune my pwm fans, qfan enabled in bios on the turbo profile setting. Im not sure about the p5k series, but on more recent asus boards it isnt possible to speed control 3pin fans of the cpu header, 4 pin pwm only.

Heh nice one setter. I have Q-Fan set to Turbo also, it's the logical choice for an overclocker!

I must say I haven't installed Ai Suite and that other EPU stuff since last year, didn't find anything it offered me that can't be sorted in the BIOS.

Is there anything useful nowadays in Ai Suite then? :confused:

I only really use ai suite for my 3 pwm fans, i run 3 pwm sharkoon silent eagle se's (2 on a TRUE and 1 exhaust) have them configured to run at 400 rpm at idle, only rising to full speed if cpu temp rises above 60c. The rest of it is pretty much useless, same goes for epu6, as once you alter any bios setting it renders it unusable.

Sweet! sounds uBer stable to me!

What CPU is that then?

Sounds like the Titan Fenrir is not allowing the chip to get hot enough for Q-Fan to wake up heh!

I think your all good, if you need to know anything else just shout! :cool:

I don't have a turbo setting.

I also don't have the motherboard CD and the AI Suite isn't offered under my drivers on the support site.

It's a Q9550.

I'll just leave it as is then
