Best CPU fan control software?

Whats the best software to control CPU fan speed? Speedfan does not work for CPU fans, I think it has to be plugged into the mobo case fan plug to mess with it.

I was just wondering what everyone else uses.

speedfan is a pain in the ass to set up, but i'd be surprised if it didn't control the cpu fan header. i just use the bios setting now.

Yeah speedfan doesnt work, I already use that but it wont let me change anything with cpu fan speed.

And ya, I forgot you can change it in bios settings which I just did so...thats fine.

Asus AI Suite Fan Xpert is crap and doesnt hold the settings I changed so that program is useless.

gah...ive been trying to get speedfan to control my CPU fan for days...finally coming to the realization that it wont alter CPU fans

I'd be interested in what else there is as well. I used to use MBM and havent tried it but will give it a look


EDIT: nvm...seems the creator has abandoned the project =(

SpeedFan is the best, you just have to set it up properly. Make sure you configure your PWM modes to software controlled, it's the most common error I see when people first set up SpeedFan:

ASUS Fan Xpert is useless and the BIOS holds the settings but does not apply them. Fan Xpert also decides to ignore my settings half the time and turn my fan up and down in a rhythmic pattern.

Doesn't give me the option on my ASUS P8Z68-V LE. (Manual, Thermal Cruise, Fan Speed Cruise, Smartfan IV) running the latest SF Beta.

THANK YOU!!!

I have a P8Z68V LX as well, set the PWM modes to manual, set up advanced fan control, works like a charm!!

Only weird thing is, my video card fan was detected before the last boot, now nothing, weird.

Is this in SpeedFan or ASUS Fan Xpert?

Awesome :). Can't say much on the video card fan though, that's odd. Were you using SpeedFan to control it?

no i wasnt, but speedfan randomly detects it. This current boot cycle the gpu fan is recognized, however if i restart theres no telling if itll be recognized. Not a big deal though

Well thanks for the info one the setting the PWM stuff to manual. It looks like this may have been the reason I havnt been able to use speedfan with cpu fan for a long time, even on my E6400.

So yeah, it looks like to control cpu fan, you just have to change those settings to manual.

How do you set up the advanced fan control part?

Sorry, as I was quoting your SpeedFan info I meant SpeedFan. There is no Manual option where you have indicated in your screenshot.

I do not have the Software Controlled option available to me.

Managed to get SpeedFan fan speed control working on my Gigabyte GA-Z68X-UD3P-B3 board for the 2 x 4-pin fan headers I have. They are happy controlling my fans.

However I have had zero success in this regard with the 3-pin headers. I know I'm probably out of luck here but has anyone had any experience with this board and/or SpeedFan that can help me jiggle and poke the settings to see if it's possible?

I wonder if it's named something differently. Try selecting different options and seeing if it allows the control to work.

Glad you got it working :thumbsup:.

It's been that way on all Gigabyte boards I've used for several years. The 3-pin headers seem to be read-only. I've fooled with them for awhile in SpeedFan and can't get any kind of control to work through it (even on/off).

Ah, most unfortunate but not unexpected. I was rather hoping that the 3-pin headers could offer control for the 230mm fan I have on the way.

Looks like another manual control job.

Clearly, the answer to the OP's question is uGuru! It could control every fan header on the MB and it was awesome. Good luck finding a modern board that can use it though. :(

Somebody should have bought that IP and continued with it.

I haven't had any problems at all with ASUS' Fan Xpert. I think it reverts any user customized configuration back to the default settings whenever you do a BIOS update, but it doesn't lose the settings. You just need to go back into the software and select 'User' for each of the fans.

You, good person, have won the Internet today. Why this selection to Manual isn't part of Speedfan's standard setup is beyond me. I've used Speedfan for years just as a monitor but never as a controller, until now. If I could only figure out how to prevent it from always creeping back up to the maximum set speed...

I also agree that speedfan is the best. Just make sure you set it up properly and it works like a charm. I like having my CPU temp displayed in the taskbar.

Now that I know how to properly use SpeedFan, I've played around with the temps a bit and I figured out why the fans would always creep back up to 100% even under practically no load - I had set the Desired temps too low. I have an i7 2600 in a Silverstone GD05B with a Galaxy 560 Ti, etc. This case is small, so there's not a whole lot of air flow. What I figured out is that I really can't get my CPU temps below 38*C, even with all of the fans at 100%, but my Desired temps set in SpeedFan were set to 32*C so the fans were working up to 100% without ever actually getting to that Desired temp. Now I have my Desired temp set to 45*C and not only are the fans running at super low speeds but my temps are still 38-43*C. It would be nice to have a lower ambient temp but I won't complain since it's not overheating and I can't even hear my PC anymore.
