PC Fans Throttling

[gazum123]

Hello,

My pc has been perfect up till a few days ago where all the fans in the system including CPU & GPU fans have been throttling up and down constiantly. I have noticed the temps have gone from GPU 25-35 up to 30-45 even on idle and the CPU upto 40 without doing anything. PC is spotless inside however I noticed the CPU cooler is alittle warmer & the GPU is also.

My Specs are:

Gigabyte 970a-ud3
Bulldozer fx6100
16GB Kingstone 1600mhz ram
Nvidia 9600GT 1GB
ALPINE 700W PSU RED 120MM FAN
OCZ 120GB SSD
500GB Barracude HDD.

Any help would be great.

How's the airflow through the case? Are your case fans working properly?

My front Fan started making a grinding noise then soon as I removed it and reinstalled it seemed to be alittle quieter but now you mention it. The fan does not seem to be pushing as much air through as it did.

I did forget to mention when i checked HWMonitor my -12 Rail seemed to be changing alot from around -5 to -12.3 every couple of seconds it would jump around

Maybe you PSU is going bad then. Also is your computer really dusty it can be a big deal sometimes, try cleaning it out.
