HELP! What Are Your CPU Temps in Bootcamp Under Max Load?
I have a 2019 MacBook Pro 13", i5-8279u (2.4GHz up to 4.1GHz), 16GB RAM, 512GB SSD.
I'm just trying to diagnose an issue I'm having. My CPU reaches 100 C instantly when play CPU-demanding games, throttles down to about 80 C, and the cycle repeats. I have tried disabling Turbo Boost, which fixes the issue but limits performance in CPU-demanding games. Is 100 C normal for this MacBook? Can it safely run at a consistently throttled 100 C at max load? It may be worth noting that it never goes over 100 C. Does anybody have a solution, since it would seem undervolting is no longer an option?
I would appreciate your input, since I've been boggling my brain for a good 24 hours.
Having the CPU sitting at 100°C for longer periods of time really isn't good for the hardware. Luckily you can limit the CPU performance in windows power management. Set your max processor state from 100% to 99%, this way turboboosting will be disabled. That should keep your CPU temperature in check. You should also download Macs Fan Control and set a custom fan curve.
@charlieboymusic, that's the same temperature I get at 99%. For most games I go down to 70-80% and this keeps the temps below 70°. For some games like Trackmania 2020, I have to leave it at 99% for optimal performance.
@charlieboymusic, I use Throttle Stop, and set different clock speeds for different tasks in order to keep the CPU under 100 Celsius. It's a very useful tool, allows you to change clock speed, therefore effectively controlling heat output. This way you can keep high clock speeds for normal tasks without permanently setting your CPU to base frequency, although @viktor_g solution works great if you just need lower temps.
