I have overclocked my fx 6300 to 4.3ghz on the GA 78lmt-usb3 rev. 5.0 motherboard using the cooler master tx3. I know I can do 4.5ghz (tested it using prime95 for two hours) but it sits close to the 80 C mark for the North Bridge/VRM (I'm not sure which one HWmonitor is registering as TMPIN2). My case is a XION XON-560 mATX/ ITX Meshed Mini Tower. The question I have is if anyone has any suggestion for cooling the North Bridge/VRM using a 90mm or 120mm fan (or any size that can fit in the case). Please include position of the fan whether to have it as intake or exhaust. I can post pictures of the rig if necessary.
