Ryzen 7000 series all have a TjMax of 95C. I was quite surprised to observe this getting one recently. The motherboard's fan controller seemed unconcerned until the chip hit 100 and even then didn't throttle the CPU, it just cranked the hell out of the fan.
I guess if they've determined it's not detrimental it's fine, but on a MacBook Air with no fan, I can't imagine you've left much performance on the table by heat-soaking those extra ~20 degrees. The way these chips heat up that's gotta be just a few more seconds at full speed.
- jorvi 3y agoNot sure if you’re aware of this (and if you’d be comfortable doing it, considering the risk), but delidding the 7000 Ryzen’s and applying Liquid Metal cooling paste drops average temperatures by ~20°C (!). Remember to apply to both the cooler and the CPU. This is because the Internal Heat Spreader for 7000 series was made primarily with cooler height compatibility in mind. It’s compatible with all previous (aftermarket) AMD coolers, but because the chips are lower height they had to make the IHS thicker which lowers the velocity of heat transfer.
- duffyjp 3y agoToo risky for my taste! What I ended up doing is lowering the TDP in the BIOS from it's default 105 to 85 watts and now temps are great. I have a 7700X. Before doing that I tried lowering the max temp instead but I think 100+ watts is just too much for the cooler I have and I couldn't tolerate the noise. I'm sure I've lost some performance but I can't tell the difference.
