socialconflicts Posted July 8, 2012 Posted July 8, 2012 so my issue. i have a hyper 212 evo and when i boot the comp the fan is spinning. but after windows loads (i leave it plain just in windows mode without doing anything) the cpu fan stops spinning... any reason why this would happen?

Waco Posted July 8, 2012 Posted July 8, 2012 Are you using any software to quiet then fan down? Does it spin up if you load up your CPU? Share this post Link to post Share on other sites More sharing options...
socialconflicts Posted July 8, 2012 Posted July 8, 2012 i dont think i am.. maybe through bios it might be setting it to be quiet? if i load like lets say... firefox.. the fan moves a tiny bit, but then stops. if i reboot the pc. the fan stays on throughout the whole loading process.

Waco Posted July 8, 2012 Posted July 8, 2012 If it spins up when you fire up a game it's got to be some kind of software controlling it in Windows. Do you have all of your motherboard utilities installed? It could be one of them. Share this post Link to post Share on other sites More sharing options...
socialconflicts Posted July 8, 2012 Posted July 8, 2012 just got done with the build today and it loaded fine (at first the fan was spinning kinda fast) i installed the gigabyte software for my z77 and i guess after that it seems more quiet?

socialconflicts Posted July 8, 2012 Posted July 8, 2012 im running prime95 for a test and the cpu cooler fan is on.. so im assuming its on an idle base? Share this post Link to post Share on other sites More sharing options...
Waco Posted July 8, 2012 Posted July 8, 2012 Yeah sounds normal to me if temps are okay. I bet it's the mobo software doing it. Share this post Link to post Share on other sites More sharing options...
SpikeSoprano Posted July 8, 2012 Posted July 8, 2012 If I were you I would check to see if it is software that is making the fan stop,usually the software just slows down the rpm of the fan not stop it. You want to make sure it isn't a faulty fan or mb problem. Share this post Link to post Share on other sites More sharing options...
socialconflicts Posted July 8, 2012 Posted July 8, 2012 ^ even though its on when programs are running? that is also what i thought "i dont think it should stop.... maybe slow down yes.. but not stop..." Share this post Link to post Share on other sites More sharing options...
socialconflicts Posted July 8, 2012 Posted July 8, 2012 so i set to enable my MOBO to detect cpu fan fail through a noise. and well it seems it detected it cuz fan stopped and noise started to go offf... ugh.. so i assume it was a bad cpu cooler?

Waco Posted July 8, 2012 Posted July 8, 2012 No. The slow speed setting is just below where the fan will spin. I have my HTPC set up that way so it's only spinning when under load. If you raise up the minimum speed/duty cycle on the CPU fan it'll stay running instead of stopping. Share this post Link to post Share on other sites More sharing options...
socialconflicts Posted July 8, 2012 Posted July 8, 2012 (edited) so the fan only seems to 'fail' when it reaches windows i load it up, while in bios the fan is running as it should. when it reaches login screen, the fan is running as it should (the screen where i have my password to login) after that when windows loads 10 seconds after the full loading, the fan stops. and i have the noise telling me 'fan fail' (fan stopped) ima take out my cpu and put in my stock cpu and see how it handles then. if its fine after that i know it was a faulty cpu/cpu fan?
