Heatsink Removed, the original TIM is spread evenly, i was surprised!
Cleaned it up, such a shiny beauty!
Zip tie'd 2 Cooler Master R4 120mm case fans I had laying around, not the quietest option but are fairly good at moving air (would have rather used Cougar V12BB fans, they are nice and quiet and push great air.
Installed the original heatsink back on, using IC Diamond TIM and removed the original fan and shroud.
Installed on the DWood tech bench on an ASRock Extreme4.
Being powered by 2 convenient 3-pin adapters.
Sorry for the crap pics at times, Cell phones aren't the best under low lighting.
Anyways, here's the temps:
Wish i measured the stock heatsink, but oh well. This solution is much quieter and can be even quieter depending on the fan used and the use of a fan controller.
