[Solved] CPU overheating

[Ashton Drake]

I have an Asus rog zephyrus g14 laptop with ryzen 9 5000 series and rtx 3060 6gb with 16 gb ram, I can play most modern games fine on high settings and temps being around 70-80 degree celsius and on idle it stays on 40-60 degree celsius but playing helldivers 2 my cpu temps go above 90 or 95 degree celsius and it becomes physically uncomfortable as the metal chassis of my laptop heats up. my fans work normal and they ramp up on high temps, Ive cleaned my laptop of all dust as well, and my cpu has liquid metal instead of thermal paste, Ive tried to cap frame rate from within the game and from nvidia control panel to as low as 30fps but it still heats up the same, changing graphics settings seems to not do anything about this as its cpu which is heating up and not gpu and all my settings are on medium or low, Please help

Edit: problem solved, in “known issues” arrowhead mentioned a problem with “screen space global illumination” on amd gpus and asked disabling it, but I had nvidia gpu and my problem was cpu temps so I didn’t bother at first but ultimately tried it out of frustration and it worked, disabling ssgi reduced my cpu temps by almost 20 degree celsius and played an entire operation without temps ever reaching 90 degree celsius.

Was the liquid metal applied 100% properly? How long ago (has it degraded and dried out causing a bad connection between the lid and the chip?

Really though, you mentioned it's a laptop and quite frankly laptops are a form factor that cares about heat build up last. Laptops really don't have proper cooling to do much. Them heating up and being uncomfortable is honestly the sad truth about gaming on them, although 90-95 is a bit rough.

Ironically limiting your frame rate might have the downside of giving the CPU more to process by taking a load off of your GPU, so keep that in mind and look in detail.

the laptop came with liquid metal stock, I haven't touched it. In most cases limiting the frames causes cpu temps to go down, I cap frames to 60 on all games, if left uncapped I get frame fluctuations and stuttering as is normal if not using vsync, regardless I dont need all the 120fps that my monitor can do, im fine with gaming in 60 if it reduces the load on my laptop which it does in most games from what Ive seen.

Same problem, sadly that fix did not work for me.

Mine was around 86C until I tinkered with Nvidia control panel settings. Put Helldivers 2 in performance. Then set every setting that can be set for performance, to performance. That lowered the tempt down to 70-76 now consistently.

Also I noticed that for some reason locking framerate in game makes my system heat up more. Weird but I just again did the FPS lock in Nvidia performance settings and did not do it in game settings.

That's quite high for idle load on a CPU. If you are getting above 50c on an idle CPU load that is bad. Really just with the OS running your CPU temp should hover around 35 maybe 40c. Idle mine is below 35c (on a desktop) and it's 5 years old (cpu radiator needs a proper clean though the temperature wouldn't tell you) I would make sure your air vents are clear of dust and/or invest in additional cooling.


If you have hardware overclocked (boost) enabled on your mobo this may also cause very high temperatures during this game. I turned mine off and now it's lucky if it hits 50c (as opposed to ~60c underclocked with low settings and 70-80c without underclock low settings)

Yeah its a known issue that in game frame rate limiter does not work and increases cpu usage and temps, use nvidia control panel to cap frame rate.

I have around 45 idle, but it never goes higher tan 70-75 when gaming either. And I have a corsair iCUE h100i elite capellix XT...
