Solved case fan for msi ms-7548 motherboard

Specs: Linux i686
I`m presently using a cpu fan for a case fan. If I install a larger 92mm fan, I get an error system fan failed,press f2 to continue. The cpu fan works fine, but I have to use wire ties to hold it in place. Is there a reason the larger fan gives me an error message? Is their a rpm problem?

✔ Best Answer
Try a different fan, that one could be bad, they are not expensive and if you just purchased it, swap it out where you purchased it for another one.

You have to be a little bit crazy to keep you from going insane.

I don`t know if you received my last post, but the fan I tried came from my older hp pc & it works perfectly. Full story. I had to replace my msi board in my newer hp. It did not come with a case fan. I replaced the board with an exact msi board from e-bay. It came with heat sink & fan but no processor. I installed my phenom x4 9150e. upon startup I get system fan failed. installed an old cpu fan with wire ties, the machine fired up perfect.Tried to install a 92mm fan, (for looks) and again get system fan failed. Like I said the 92mm fan does work. I wonder if it is in the chip set for this board. I can`t find nothing in the bios. Thanks for any input.

Since trying a different fan would probably not solve the issue, I was wondering if you resolved this? I have seen the error before when fans get replaced. I remember a post once which said something about adding a one time 5volt jump to the pins and that cleared the error but I am not seeing Power Up Diagnostic pins on the motherboard.
