Wow, a 125 Watt dualcore :lol: Looks like you took the right measures to silence it though :P Just wondering, are you using PWM or voltage for controlling the speed of the fan? If you use PWM, you should be able to get the fan down to 300 RPM. the X2-6400 was the best bang for the buck (80 euros) w...

I now use a mugen 2 to cool a X2-6400 (125 watt TDP) and control speed with speed fan. In a silent room at 25 °C : i get a around 31 °C idle temp with 450 rpm (NO noise... it is the minimal speed to get it spinning reliably...) it stay like this (bellow 45 °C) except during gaming and video encod...

I am happy with the mugen 2 ...

Hi, I would use a 92 mm PWM fan and use a software to control speed according to CPU temperature. speedfan is great and it work with this motherboard. In speedfan you can set 3 different rotation speeds according to temperatures : - bellow target temp = minimal speed set in speedfan - between target...
