Next-gen Intel Desktop Processors Might Run Hotter Than Previous Generation
Intel allegedly increases maximum temperature for Arrow Lake CPUs.
Recent reports state Intel has increased the TJMax (Maximum Thermal Junction) temperature for the company’s codename Arrow Lake and Panther Lake processors to 105 °C. Bear in mind this information is according to a leak and should be taken with a grain of salt.
Intel processors typically feature a TJMax of 100 °C, which hold true for Alder and Raptor Lake CPUs and will reportedly be the case with the next-gen Lunar Lake processors. However, the new Core Ultra (codename Meteor Lake) have their TJMax set to 105 or 110 °C, depending on the version. The companies upcoming Arrow Lake and Panther Lake CPUs seemly have the same TJMax temperature.
TJMax is the highest temperate a processor can experience before activating internal thermal controls to reduce power going to the processor to try limit temperature, which often leads to performance loss. The TJMax thermal limit varies by product. For example, laptop CPUs usually have a TJMax of 100 °C and the TJMax of desktop CPUs can be set up to 110 °C.
If the TJMax is going to stay at 110 °C, that is no cause for concern but, may lead to uncomfortable situations for laptop users. Should TJMax be increased on Intel’s laptop CPUs, running at the increased temperatures may lead to an uncomfortably hot device. Conversely, the increase in TJMax is likely means Intel expects their silicon to handle the head, which is good.
