I have a 4790k insalled on maximus vii formula. The cooler is noctua nh-d15s, case is thermaltake urban t81 with stock coolers. Thermal compound is mx-4. After changing thermal compound (early used noctua stock compound) I ran aida 64 and got thermal throttling up to 20%. After removing front door and dust mesh from front and top themps droped to 92 degree. But I still think its to high. It s about 26-30 degree in room, can I have some advices, what should I do?
