Case Fan Speed

[Zeorth]

Hi,

 

I have installed 3 LL120 RGB fans and 2 12V DC Brushless fans from Corsair. However, when running my computer they either go from extremely silent at times to speeding up and getting really loud. Is there a way to find a balance between this or will I have to live with them going from quiet to loud to quiet to loud all the time?

It depends where you have plugged them in and what that header is using as a reference for its speed.  Go into you BIOS and use the fan settings there to make changes.

The 3 LL120 fans are plugged into CHA_FAN1, 2 and 3. The DC fans are plugged into EXT_FAN and CPU_OPT.

OK, then in BIOS set them at a constant speed and they won't change, if that's what you want.  CHA_FAN EXT_FAN and CPU_OPT are probably referencing a temp sensor or something.

CPU header follows CPU temps. How rest are setup by default is said in mobo manual.
