IHS thickness, OC, temperature and heat transfer

When buying a new Intel processor, we have to take into account that they are chips that consume a lot. We see this reflected in really high temperatures, even using a high-end liquid cooling system. However, these are not so worrisome if we take into account that the Ryzen 7000 reach 95 degrees consuming much less. Knowing this, overclocker der8auer has had an interview with a intel engineerwhich solves doubts about their Core 13 CPUsabout how control high temperatures and much more.

An Intel engineer talks about the sweet spot of CPU thickness


The well-known YouTuber and overclocking expert der8auer has been in charge of organizing an interview with an Intel engineer. This is Mark Gallina, a senior thermal analyst, whose job at the company is to look at how to effectively dissipate heat from Intel processors, and will talk about many other topics. First of all, he and der8auer talk about how the thinner die contributes to better temperatures. As we well know, heat will be generated in the CPU and will transfer upwards, passing through the IHSthe thermal paste and ending in the sink.

He also mentions the huge thermal conductivity differences that exist between different materials. For example, the use of copper in the dissipator it carries about 390W/mKwhile the use of Liquid metal as TIM we would talk about 36W/mK. The objective that Gallina mentions is the fact that you have to find a balance between all the layers. By making the die thinner, what they do is improve heat transfer, but there is a limit that should not be exceeded, so you have to find the sweet spotwhich positions in 0.2 to 0.3mm.

The next question for Gallina has been about the manufacture of CPUs, where exact figures have not been given, but we are talking about thousands of die created every day. There has also been talk about the use of TIM welding, something we already saw with the i9-9900K. If we remember that time, der8auer already complained that the welding was botched and after making delid and add liquid metal, temperatures improved by almost 10 degrees. We’ve seen the switch between solder and thermal paste for several generations, and depending on the processor and other factors, the difference could be significant or minuscule.

Another hot topic is overclocking, where there are cases where you have a processor with higher voltage and high temperatures for many years and nothing happens. Mark Gallina assures that indeed high temperatures are safe as a general rule and have the Intel Core 13 CPU at 90 degrees It doesn’t mean that I’m going to die soon. In fact, it ensures that the 100 degrees of temperature that Intel puts in the specifications is where the CPU Low frequencies for security. Although he also warns that there is no global answer for this, since it will depend on the use we give to the processor, since it is not the same to have it at rest than in constant Cinebench load.
