My computer gets pretty hot and loud in games. For example Darksiders II on max. I think it's the processor stock cooler. I have an amd phenom x945 x4, overclocked to 3,6 ghz. I am considering getting a Scythe Mugen 3 cooler. Any thoughts? It my also be my 7870 XT, but my processor cooler seems the loudest. I have a MS-TECH Raptor case.
