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.

You don't need the big fan at all, check the link you can see the small fans will get the job done. http://www.overclockers.com/forums/showthread.php?t=733...

With a 4+1 POWER DESIGN you won't get much more from that board , it's not an overclocking board.

Thank you cin19 for the suggestion. I will do some measurements and see what I can fit.

SR-71 Blackbird, people told me I wouldn't get 4 ghz from this board and I have managed 4.5 ghz so far. Please be more constructive with your feedback. Thank you.

I wouldn't OC much more than what you can get without voltage boost and/ or very minor voltage boost. It's not that your board isn't an overclocker, it's that any board with a 4+1 or 4+2 power phase is good for casual overclocked. You should be able to at least get 4.2ghz across all six cores, but for longevity I'd really carefully gauge if you should go over that(heat wise). You're CPU is 3.5GHZ and when turbo kicks in, it basically disables 3 cores to attain the 4.1GHZ speed, which means voltage doesn't need to be boosted and heat is minimal. In forcing an OC, you are forcing it across all 6 cores(unless, you disable 3), and so voltage usage goes up and heat significantly raises. I'd say lock all 6 at 4.2 and call it a day. Maybe 4.3 if you don't see a temperature difference and/ or voltage is only marginally raised. Not CPu temp, but temp of your mosfets. Most of these(pre-FX) chipset boards tend to already be hot with FX processors in. At least, the 8-cores ones anyway.

This board has no VRM or northbridge sensors that register for software use.

TMPIN2 is CPU package plus 15c offest. It's only useful to estimate cpu idle temps. Use the cpu core package to verify cpu temps under load. It will be accurate above 40c and under load. Core package will not be accurate below 40c.

TMPIN1 is error related to CPU package or possibly socket temp.

TMPIN0 is motherboard temp, a small thermistor in the left bottom corner above the ITE chip.
