Question Really weird bug with motherboard and fan

[Harry_campbell]

I have just bought a gigabyte b250m ds3h.
Whenever I open a steam game the fans go to near max rpm and stay there even after closing the game. System information viewer doesn’t affect the fan speed, speedfan doesn’t support this motherboard. I don’t know what to do

Check your CPU temperature using MSi Afterburner, if your processor is getting hot your fans are going to spin at high RPM, even after you're finished gaming due to it continuing to cool off. If your PC didn't get so loud before it could be a sign of your computer clogging with dust.

My cpu is getting nowhere near hot enough to spin the fans this much, it’s around 30-35degrees, the fans are brand new and clear of dust. I can open the game for 10 seconds then close it and the fans will stay on for ever (I have never heard them stop even after leaving it over an hour)

30-35 degrees seems low for a gaming load, what program are you using to view the temperatures?

I’m not even talking about intensive games, I open something like factorio and just the menu freaks the fans out. Whatever is happening isn’t because of my cpu temperature

I have checked the cpu temps in speedfan and msi afterburner and both agree with each other

 

[Harry_campbell]

This only started happening after I replaced my motherboard with a cheaper one. I haven’t changed any settings and I’m 90% sure I have all the required drivers

A long shot would be to change your Windows power plan to balanced if it's on high performance, and change the advanced options under processor power management, system cooling policy to passive from active. Finally, if that doesn't work go into your BIOS menu before booting into windows, find any fan speed settings and change them to "quiet" or similar.

I have done all of that, no effect

Are you able to plug your CPU fan into another fan header on the motherboard? It will give you a warning on boot but maybe for whatever reason the PWM feature has failed on your board.

I have another fan plugged into the sysfan and they both behave the same way

If I buy a fan controller, is it safe to plug my cpu fan into the fan controller or is that only for case fans

Yes, it would be safe to use a fan controller, but remember that you will have to increase the fan speed when your temperatures get high, or else your system will thermal throttle itself.

Don’t most fan controllers have an auto setting?

You changed motherboard. Did you reinstall windows after this change?
If you can't reinstall windows, then first - reinstall chipset drivers.

BTW - what was the old motherboard model?

 

[Harry_campbell]

I went from MSI Z170A gaming m3 to the one I mentioned before, and no I didn’t reinstall windows

Unless the fan controller can read your CPU temperature, the only automatic feature would be to run it off of your case temperature. Try doing a BIOS update for your motherboard here if you haven't already.

It says I can’t install them on 64 bit windows

 

[SkyNetRising]

Install chipset drivers for your new motherboard.
If that doesn't help, then reinstall windows.

Motherboard change is major system change. Windows reinstall is highly recommended.

I’ll give it a go

Changing a MB is a Major change.
I would absolutely recommend a clean install of Windows.
Back up any important files/documents/favorites/etc.
Then re-format and install Windows then install all the necessary drivers (Chipset/GPU/etc./etc.).

I have re installed windows since and there is still no change. Nothing I do to change the fan speed actually has any effect

 

[DMAN999]

Try using Argus Monitor instead of Speedfan (which is very outdated):

Or you could try using APP Center and System Information Viewer / Smart Fan 5 from the Utilities Download page for your new MB.

Gigabyte System Information Viewer(SIV) and Smart Fan 5 Advanced Fan settings

Good day! I have a problem understanding this software menu, The Smart Fan 5 Advanced Tab. I mainly want to use this so I dont have to download additional software to manage my cooling. I want my computer to be so silent that I can barely hear it when idle, doing easy tasks as browsing, watching...

Problem solved, I’m just a massive idiot. My cpu fan wasn’t going mental it was my gpu fan. One of the fans was blocked by a cable so the other 2 were freaking out to compensate. Sorry for wasting everyone’s time but thank you for your help
