So I just built my new comptuer and have noticed that my Case fans are running at full speed
and not throttling at all, they are running at full speed even when the computer is hibernating. I was
wondering what I should do to fix this I am not sure if it is something I have to change in the BIOS
or what.
my motherboard is MSI H81M-P33
CPU: Intel i5 4460
Graphics Card: R9 290
OS: Windows 10 64 bit

I would see if its a software or hardware issue that is causing this. Easiest test would be to download and install to USB Stick or burn to a DVD Linux Mint 17.2 or 17.3 and boot computer off of that and then tell Linux to shutdown. If Linux Mint shuts down after removing the disc when it tells you etc then you know that its not a hardware or BIOS setting and its some problem with Windows 10 completing its full shutdown process.

What kind of fans are they? What connector do they use?
-
They're 3 pin connectors and I read that only the 4 pin ones throttle, but that doesn't seem right because my case fans throttled with my old motherboard...
-
Speed control of 3pin fans is very much motherboard dependent, I imagine that your new board doesn't support this. For case fans I'd just get a basic fan controllers or quieter fans. You could also get fans with built in speed controls which could be quite a neat option.

Cameron could I use a program like speed fan to control them?
Or could I go into the bios and change something?
It's just strange to have them running full speed at all times lol.

Wefro_froyas,
Could you please give a link to the motherboard documentation?
It may be that mother has some options that have to be set, but each mother is different. Documentation needed.
-
Did you choose controllable fans that are compatible with the motherboard?
-
This photo from a manual for the motherboard.
It explains that you need a four pin fan for temperature control. If the motherboard sports it.
