Removing the IHS from a processor is an operation that should not be carried out without experience, but Der8auer shows us the benefit that can be obtained from it.
The IHS, for integrated heat spreader, is a piece of metal put in place by Intel and/or AMD to protect their processors and ensure a larger dissipation surface so that cooling is more effective.
Except that said IHS can today be an obstacle, and whether it is Intel or AMD, its removal can greatly improve heat dissipation. As long as you don’t do anything, of course.
Remove IHS? A delicate maneuver
Well known to fans of overclocking and hacks of all kinds, the German Der8auer has launched into the delid of the Intel Core i9-14900K CPU. Delid is the action of removing the IHS that we have just talked about.

Removing this metal plate is not within the reach of just anyone, especially as long as the processor is new. Indeed, for the Core i9-13900K, and under the leadership of Der8auter in particular, tools have been distributed in order to make the operation (a little) simpler. For the moment, this is not the case with the Core i9-14900K, and we therefore invite you to exercise the greatest caution.
Der8auer, however, seems to indicate that the delid of the Raptor Lake Refresh is not very different from that of a Raptor Lake processor, while Intel has not changed much in terms of the IHS… like the rest of the processor , one would be tempted to say.
Up to 13°C cooler on high-performance cores
However, what has changed is the temperature that the Core i9-14900K can reach during slightly demanding tests. Consumption is significantly increasing, and to carry out our measures, we were forced to change the cooling system.
According to Der8auer, and this is not really a surprise given previous results on older generations of Intel processors, the removal of the IHS (and the use of Conductonaut Extreme) made it possible to reduce the temperature of about 10°C on the efficient cores, while the efficient cores saw a more modest drop, but still around 8°C.
More interesting, Der8auer then used a Contact Frame signed Thermal Grizzly for the 13 CPUse generation. Not only did the thing work, but the drop in temperature was even clearer: around 13°C less on the high-performance cores. Der8auer emphasizes, however, that these results should be verified on other Core i9-14900K before generalizing.
