Help PLEASE! :(

i just bought 2 af 120 fans and i connect it and one goes full speed and doesn't show rpm while the other one works fine and i can control i am on a msi 970 gaming sys 3 fan no work and it 3 pins while sys 2 fan has 4 and there both 3 pins.

Make sure in the BIOS of your motherboard that the sys 2 header is setup as DC voltage control since you are using 3 pin fans, it sounds like it defaults on PWM and if that is the case it would explain why it only runs at full speed.

how can i find out and is there a adapter that i could use

If you have a 4 Pin PWM fan and are able to change the speed on that header then for sure it's PWM enabled but most that have that capability allow for switching between that and DC voltage control, this should be either in the BIOS or done with MSI Command Center.

 

If it's fixed and can't be changed you can always get a fan splitter to use on the other header for both fans.

ok but photos please idk where to find it

It should be usually under fans, monitor, or something like hardware monitor in the BIOS. 

 

Command center is a software download from drivers and utilities:

not on command center should i try in bios in that case where is it

Try looking around to see if you find something called hardware monitor, from what I can tell that is what MSI named it.

so i can't find it but could i get a dual 4 pin to one 3pin on the sys 1 and control both of them so they have the same speed?

Yes you can use a splitter on that single header to control both fans at once, and they will have the same speed.

 

Anyone else has a board that may be more familiar with the BIOS layout for the fan control. It should let you change and vary it there.

Yes that would work, I'm just wondering though what are you using to control your fans if your not using the BIOS or MSI Commander, Speedfan?

[WebPlayz]

bios and msi command center

Hmm odd they don't have a way to select what control type you want or if it does it automatically.

[WebPlayz]

no you can select the fans in bios its clickable

But that only lets you change the RPM not the control type to PWM or 3 pin which is odd, unless it's only capable of that in Commander center, which is inconvenient.
