Problem with software based fan control

[Ramzez]

I have recently bought a new rig. It has Asus Maximus VI Extreme motherboard. The rig also contains four SP120 quiet editions from Corsair, which are connected to the MB headers. However there is a problem. I use the AI Suite 3 for the fan control, but everytime I reboot the computer, the fans are barely turning (and whining because of it). Everything works fine during the initial boot, but when the OS and the AI Suite boots up, the fans slow down to a crawl. When I go to the AI Suite, it claims that my fans are spinning at tens of thousands of revolutions per minute. If I click any of the presets (Silent, Turbo, Full Speed, etc.), the fans go to the right speed and the software then recognizes the right RPM's. I've tried reinstalling the software and I have done custom fans speed setups, however the problem remains.

 

I understand that this question should probably be posted directly to the ASUS forums, but I don't have account there and I wonder, if anyone else has had this problem and knows how to fix it.

AI suite is buggy.................try something else.

Have you tried setting them at a bios level first (so they have a boot speed) then controlling as you wish with the software once you have booted? I can't think of much else you could do aside from ring Asus up and talk to them about it.

Dont use the presets. presets are for nubs. 

 

 

theres manual options once you get in there, turn the speed up to a silent woosh

 

 

 

 

Those quiet edition do make motor noise...

I have set the BIOS settings correctly and like I said, the problem occurs when the AI Suite boots up. Before that, the fans spin at correct speed but when the AI Suite takes over, the fans slow down considerably. It's annoying because everytime I boot up the PC, I have to go to the AI Suite and click one of the presets and then return the custom plan to get the fans to spin at the right speed.

 

I'm starting to wonder this being a software bug. I guess I have to contact ASUS about it.

I don't use the presets. I have a custom fan speeds enabled. However to get the custom fan speeds working, I have to click one of the presets and then return to the custom plan in order to get the fans working properly.

You could use speedfan to control your fans. It is pretty awesome! You could create curves for both your cpu and gpu temp so that the case fans ramp up when either component gets hot

I know, i went back and re read. my bad.

 

Still thinking it's the fans, Ive heard them before

Uninstalling the AI Suite seems to have fixed the problem for now. The fans whine only when they spin at really low speed. However I set fixed speeds for all of them directly from the BIOS and uninstalled the AI Suite and now everything seems to work fine. I would have liked a dynamic fans speeds, but for now I have to live without it. Hopefully ASUS fixes the issue, since it's clearly a software bug.

 

I have to look into the speedfan software. Thanks for the recommendation!

I have the same motherboard and i got the same problem as you. so i decided to get a proper fan controller. This goes the same as well with my NZXT 200mm case fan.
