Motherboard Fans. How to turn them off?

TheNaitsyrk · Sep 17, 2015

Hi, I have GA-Z87X OC Force motherboard and the fan that is built into the motherboard is causing lots of noise. I want to turn it off as I have no access to the cable to turn them off. Fan is located right next to CPU socket. I can see fan BIOS options like:
Reset Case Open Status
Case Open
CPU tenperature warning
System temperature warning
CPU OPT Fan fail warning
1st to 5th system fan fail warnings
CPU Fan speed control
CPU OPT Fan speed control
1st System fan speed control
2nd System fan speed control

Yet I can't find the option to stop the fans.

The fan speed control should allow you to set it to 0. That said which fan is making the noise? If its your CPU fan (plug located next to the CPU socket) turning that off is a BAD idea.

From the manual

HP_PWR_PCH
/HP_PWR (Chipset Heatsink Fan Header)
The power connector provides power to
the fan on the Chipset heatsink

you could try unplugging that, however you may then get overheating issues

You can remove the motherboard and on the back there are screws that hold the heatsink in place. After removing those you can detatch the heatsink from the VRM's and unplug the fan. Put the heatsink back and screw back in.

Also you could just jam the fan to prevent it from spinning but I do not know if there are any consequences to this.

Lastly, I assume you wen tin BIOS and check the settings to see if there is a way to change the fan speed all the way down to 0RPM or disable the fan entirely. I would even try out increasing the fan temperature speed control for that fan way high so that it only spins slowly even on high temps.

Green shows where to unplug it, but I can't do this in my current setup, that's why I need to know how to do it in BIOS.
Red shows the fan that is causing the noise.

I don't think that a fan that is cooling nothing, will affect my CPU temperatures. This fan is 4-5cm big....

TheNaitsyrk · Sep 17, 2015

WYNIR0 :

I get that, but I can't unplug it and a fan that has 4-5cm width will not cause overheating issues since it's meant to cool water loop which I don't use. I also have Noctua DH-14 CPU cooler so I'll be fine. I just want to get rid of the noise.

WYNIR0 · Sep 17, 2015

The fan won't be there for no reason, it seems to be cooling the chipset.

Have you tried cleaning the fan?

Illumynization · Sep 17, 2015

TheNaitsyrk :

The fan is simply providing extra cooling to the VRM's and MOSFET's that regulate power to the CPU and rest of the board. While they do get warm, a passive heatsink is plenty to keep them stable. Removing/unplugging the fan will not affect performance.

For the 3rd time, I can't unplug it with my current setup. I would like to disable it in BIOS or perhaps SpeedFAN is this possible? All I want to do is to get rid of the noise from that fan.

TheNaitsyrk · Sep 17, 2015

WYNIR0 :

It's meant to cool the water cooling loop I'm NOT using so for me it's useless. I just want to get rid of the noise by turning it off without pulling any cables from the motherboard. BIOS or SpeedFAN solution would be perfect, but I have no clue how to do so since I can't find it in BIOS or SpeedFan.

Again. Slow the fan as much as possible and see if the noise decreases enough to an inaudible level. Otherwise, jam or cutout the fan from the heatsink.

I wish I knew how to do so. Fan is blocked by the biggest CPU cooler you can imagine, and the cable to turn off the fans is blocked by quad sli. I'd have to almost take my entire PC apart and I would love to avoid it.

No offense but this is literally the worst advice you could ever give anyone to disable a fan in their computer. This will cause the motor to overheat and burn out. It can very well cause any number of other issues including an electrical fire.

To the OP or anyone reading this, NEVER EVER do this.

Rogue Leader :

I'd never JAM IT OUT, or PULL IT OUT. This motherboard was way too expensive to damage it just like that. I want to safely stop the fan from spinning by using a software or BIOS. I even can't do it even if I wanted to honestly.

Illumynization · Sep 17, 2015

I did not realize your CPU cooler was in the way. Other than a direct approach physically, accessing that fan through software would be the only way. If gigabyte has any software to go with that board I would check that as it may have a setting for the motherboard fans. If software and BIOS cannot help you then the only other option is to physically fix it.

WYNIR0 · Sep 17, 2015

I doubt that the BIOS or Speedfan will help you. From the manual the headers for the fan are 2 pin which I believes that they have 2 modes, on, or off. I know you say that you are unable to unplug them, but this may well be your only option.

Are you sure that these are causing the noise? Sure something isn't dangling into them?

TheNaitsyrk · Sep 17, 2015

Illumynization :

I tried Gigabyte EasyTune but it doesn't control the fan that is used for the water loop. I was hoping I could use BIOS or any other software to turn it off. If nothing works, I have to take my PC apart.

TheNaitsyrk · Sep 17, 2015

WYNIR0 :

I could put my hand barely in there in a rubber glove. I tried touching it and slightly pushing it to see if that helps, I think it kind of got quieter for a very short peroid of time but then it started to make this noise again.

It's not VERY loud... But for example, if I play Phantom Pain on 4K on max settings, you can hear it and when I exit the game the loud noise kind of stays for long? I say 4K because the fans start to rotate the most and maybe the heat does something to it.

Rogue Leader · Sep 17, 2015

OP now that I know which fan you mean, there is a plug behind the blue USB ports that needs to be unplugged to disable this fan. That is the only way to do it. I don't know if you can even reach it from the top (hard to dell) but a pair of needlenose pliers may do it. Otherwise you need to remove the motherboard and unscrew the fan from the back and you can unplug it.

BTW while this fan does provide cooling for watercooling it also provides cooling for the VRM's which is important. Just keep that in mind if you decide to overclock.

WYNIR0 · Sep 17, 2015

Can you describe the noise. In my experience of this size of fan they tend to make a high pitched whine.

tech-wreck · Sep 17, 2015

or, turn the music up.

I didn't think you would just wanted to make clear that this is really bad advice.

Rogue Leader · Sep 17, 2015

TheNaitsyrk :

It gets loud because thats a taxing game and the chipset is getting hot. That fan spins to cool the chipset. Theres a watercooling plug there as well to allow for you to add it to your water cooling loop. Because of that there is less of a heatsink but its replaced by the fan.

If you disable this fan you may well cause performance issues.

TheNaitsyrk · Sep 17, 2015

Rogue Leader :

This means that I'm unable to do it through software or BIOS. Does it mean that the only option is to unplug HP_PWR_PCH 2 pin socket that I can actually see but I can't get there unless I remove some hardware. If this is the only option, then I'll have to do it.

Rogue Leader · Sep 17, 2015

TheNaitsyrk :

Correct, its a passive fan and meant to run when the chipset needs it. Keep in mind the reason it gets loud is because you're running taxing games so the chipset and VRMs get hot. You may cause performance or stability issues by disabling it.
