Hi,

I just flashed from 1305 to 1407 (Asus P5W DH), and now my CPU fan is always at max 3350rpm and very noisy. Prioir to this upgrade my PC was practically silent, even with side panel removed to assist cooling with CPU Fan @ 1800rpm. CPU temps have dropped by 5 Deg now which is all well and good but I would prefer the extra heat and silence.

Has anyone else experienced this with 1407? And how did you resolve this? If in deed you did resolve.

I could revert to BIOS 1305 not a problem.

Or are there any decent fan control programs out there that actually know what they are doing and produce accurate readings. I'm not endeared to speedfan, I have used this in the past on several boards and it seems to me it just has wild guesses instead of actually reading the correct values from the monitoring chip(s)

I have tried as many possibilities in the power section of BIOS as I could, but they seem to have no effect at all. Except AI Quiet, which when enabled locks CPU volts at auto and enables EIST and C1E.

Any help would be greatly appreciated.

/EDIT: 100th post, I best oil my tommy gun and fix the quick release catch on my violin case :D

Have you tried asus probe? go into the config and tick, qfan and put the fan on optimal and apply.

In "Hardware Monitor" you haven't got the CPU Q-Fan setting on "Disabled" have you? The new BIOS may have changed the default setting...

Nice one Jimbo this worked :) just done it now. I will see how it behaves after a reboot a little later.

Durzel, When I next reboot I will check. I am sure I tried all options and permutations. Get back to u later

Thanks guys

If you've set it in PC Probe it may have changed it in the BIOS as well for you.
 
I ran Asus probe and made the changes Jimbo suggested. This worked and CPU Fan droppped to 2000RPM
I rebooted and I checked BIOS for CPU fan settings

CPU Fan Speed 3558rpm
CPU QFan control = Enabled
CPU QFan mode = PWM
CPU fan profile = Optimal.

When machine restarted CPU fan was at full 3500rpm, and in Asus probe preferences the CPU Qfan box had reverted to unticked. I ticked again selecting optimal and CPU fan has slowed again to 2000rpm. So my changes in Asus probe are not staying, and the BIOS settings in hardware monitor are having little or no effect.

I will reset the CMOS later and see if this resolves problem, it's a (expletive deleted) pain, I have to remove vid card to access BIOS battery.

I will try later, time for a coffee

PWM and DC.

I have a 4 pin cable and my cooler (Akasa 961) does allegedly follow Intel specs for PWM control.

In DC mode the fan still runs at 3500rpm

Changes to the profile, silent, optimal or performance in BIOS result in no change of CPU fan speed. :confused:
 
Glad it worked. :)

Anyway I have this problem too, in the bios i have qfan enabled and optimal set, yet it still runs at performance and thats noisy on a freezer 7 pro. I have to allways open up probe and select qfan or it runs at full rpm.

Im using bios a beta bios by the way, 1303 i think? anyway the bios is ignoring qfan, and the only way i found to solve this is the method i mentioned, but it has to be set at every boot.

And as you also found, probe wont keep the setting. :rolleyes:

Aye, I will try a BIOS reset and if this fails I may revert to 1305. I'm a lazy man and I don't really want to run Asus probe everytime I reboot. I could probably push the CPU further and get at least some payback for the extra noise. But to be honest, I watch TV and DVD on this machine, I also use it for music production and enjoy (require) the usually quiet operation.

I was gonna flash to 1407 but im not sure now, I might use 1305 instead.

1305 was fine for QFan operation. It's the BIOS I upgraded from. I go back there if my CMOS reset does not resolve this problem
 
Its a shame you don't like speedfan. I find it works very well. I can set any target temp and it'll slow the fan right down with a light load, even turns it off at times. With a heavy load it speeds up very quickly and soon goes down right after.

If you do want to try here is my settings

Thanks Fornowagain, I will give it a go. It's consistent failure to report correct temperatures and persistant wrong or missing SMART results on the last 3 or so boards, Abit and a Realtek. put me off.
 
I just downloaded Speedfan Version 4.30 Forn, you may want to upgrade.

Thanks again.

I let you know how it goes
 
I got all the PWM working weeks ago and I've not looked at it since, just does its thing. I uploaded a profile to the speefand site in case I needed it later, contact me if you want the ticket number.

Speedfan is much better than the last time I used it.

Your screenies were enough to enable me to set up speedfan for my system. it is working fine and reporting correct rpms and temps. I setup temp offsets using TAT as a trusted result. And I have control of all fans now.

Cheers :)
