Fans going crazy!

Hello, I just finished 2 games of Warface with Max settings (no lag) and then when I took my headphones off I could really REALLY hear the outtake fan spinning which I don't usually hear. I looked at SpeedFan and it was on the borderlines of 2000 rpm, my cpu cooler at 1500 (normal) and GPU fan at about 2000 rpm. Should I be worrying?
 
Sounds like your system was over heating somewhere, and the fans are ramping up to accommodate. Make sure your fans are clean of dust, check your CPU fan and cooler for dust as well.

It may be time for some early spring cleaning in your PC case.
 


Brand new pc mate. :/ It's doing it again, nearly 3000 rpm...

Here is a screencap. It seems to do it when Temp1 at the top reaches above 48 http://prntscr.com/6dxbry
 


Rear (Back) of the case :) Earlier I added 2 Intake fans on the side and it seemed to help a bit as the cool air goes directly onto the cpu cooler and the gpu but while gaming on like max settings (about 90% cpu usage and 97% gpu usage) the fan might go crazy for a while then slow back down. :)
