Same motherboard, same problems. I already cleaned the TIM and applied the Noctua TIM I had and it decreased my temps by a good 15C. I went to every medical shop I found and none of them had Isopropyl Alcohol, I ended up buying it in Ritchie Street for 50 bucks.
Also you might need to use your nail to scrape some of that stuff off, it was stuck on to the chip like dried bubble gum in mine.
Also could you by any chance tell me what your idle and load temps on your i7 are? And its batch number?
Thanks.
