Fan or Fan Header problem? (Asus M5A97 R2.0)

I am having fan problems. My case fans normally run at 1200 rpm but every other second, it'll read 675,000 rpm. Obviously the fan itself doesn't spin up to 675k rpm but it's quite annoying. I don't think its the fan because I tried changing around the location of the fan connection but using the same header. Please help. It's a brand new system and I updated all the drivers already. BTW, the headers doing this are for the case. CPU fan header is fine.

Not all that unusual. I have had fans read erratic too. Sometimes they will jump to crazy numbers. Same thing with voltage readouts. I'd just assume the fan's tach feedback is bad. Try a different fan on the same header.

i have this as well, i went in to ai suite and changed the fan speeds to silent and it fixed my problem (i think ) as i never see as much. however its not really a problem unless u use your BIOS everyday for some reason. or does it show up in the OS |?

It shows up on both. I might just ignore it since it's not affecting it physically, I don't think. BTW, since you brought up AI Suite, do you recommend I use this program? I feel like I can do a lot of those things in the BIOS.
Thanks for you response!

I think you might be right, but I want to leave it alone for now. It's not affecting anything physically, I hope. I might just switch the fan because the 2 fans with this problem are the ones that came with my Corsair 230T case.
Thanks for response!

i recommded ai suite for OCing ram only cpu you HAVE to do yourself as there is a possibilty that it will mess up your cpu core voltage etcc....
when you open ur bios you will see 3 mondes(balanced,power saving, and performance)
go on performance and it automatically adjust to a stable OC. but dont use unless you feel your cpu is lacking and is slow otherwise its fine.
ai suite is good however i think it adds more points of error as you dont TOTAL control over what u do to the system
