Been reading that by removing or lapping the IHS of a cpu will lower temp. Some claims that it will lower as much as 3 to 4 C. While others say only 1 C. Will it lower temp that much and if it only lower for 1 C how do we know it lower at all since motherboard temp sensor are not very accurate. Anyway my question is by using a good after market cooler we know it will lower cpu temps and lapping the heatsink also helps and using better thermal paste helps. But will removing or lapping the IHS lower cpu temp if yes than how much? And if it is worth doing it?
