Hey, so I have a Ryzen 7 5800x with an 240mm AIO this one “ID-COOLING FROSTFLOW X 240 SNOW CPU”
Now I’ve returned a block cooler because I was worried about the temps being too high. So I got this AIO and again the temps were high so I convinced myself I hadn’t seated it correctly. Taken it off and reseated but still runs hotter than I want or would have thought. Disclaimer I over think and this may be one of those times.
So on boot it can get as high as 85 but mainly between 70-80.
Then sat at idle it’ll be 30-40 then random spikes up to 80.
Opening Visual Studio Professional and ramps up again but settles around 50 when coding.
Minecraft on 12 chunks render with optifine, hits 85 on load the. Hangs around 60 whilst playing.
Same for Factorio. But not tested any other games.
Happy to make some recordings if that would help.
Thanks
Maximum operating temperature (Tjmax) is 90° for that chip. 85° is the max spike you saw.
85° <= 90°, therefore you’re good. If it was constantly right up against Tjmax, that’d indicate that something’s wrong with the cooling but the likes of 70-80° are expected of a chip of this class.
Have a check on what your motherboardois doing in the BIOS. Asus like to by default apply extra boost to give extra performance. I managed to get my 5700G with stock cooler to 4.4ghz all core with less than stock voltages, not sure on temps at the mo as I’m not at home and england is having a bit of a heat wave at the mo (tho I might have won the silicon lotto with my chip)

- my core ratio is 44
- VDDCR cpu 1.288 (manual)
- VDDCR SOC 1.35 (manual)
If I get a change to reboot in to the bios I’ll try and note down my voltage’s
Of note, My 3700x will spike to 75~ but it’s quite literally a spike, the 3x120mm fans go jet engine and quickly stabilize it at 55, 60 max on cyberpunk. Ambient temperature when idle.
These Temps are well within the operating range over time. If it detects temperature, modern cpus will self throttle, and even shutdown. No shutdowns or throttling and you are fine.
I honestly wouldn’t worry about it, especially with the weather as it is at the moment- my PC is getting about the same with a 3900x, nice noctua cooler and loads of airflow It’s been going over 30 in my office and even the best coolers can’t break that physics
Check again when it cools down, might make it easier to see if/where there are issues

To make you less anxious:
A friend of mine had issues with his (much older) PC, stuttering in games and similar but it still worked
When I took a look I found it was pegged throttling at 100deg after running for a while. This had been going on for months
Eventually found the AIO pump had completely died, any cooling was due to passive conduction through the materials and water
We replaced the cooler and now it’s been running fine for another 3 years and going
TL:DR: modern CPUs can run hot, and safely boost. As it gets too hot it will start reducing clocks but it’s highly unlikely you damage anything unless you go out of your way to overclock, overvolt or ditch the cooler entirely
What happens if you take the side panel off and you play Minecraft + Optifine? Do your temps dramatically plummet? If you see an appreciable difference, your problem is airflow.
What kind of computer case do you have? Is it a proper case with good airflow and no tempered glass everywhere that restricts it? I also don’t mean those cases with thin vents on the side and a solid panel that forces air to make a 90 degree turn. Ideally, you want airflow to go in a straight direction rather than taking hard turns (which is more restrictive).
If your case is good, do you have your fans in the correct orientation and intaking air? Do you have enough fans to balance airflow so that you have either positive or neutral pressure (NOT negative pressure)? In my build, I have 3 intakes on the front and 2 exhaust fans. The 3 intakes are set to a slightly higher speed than the 2 exhaust fans so that I have optimal positive pressure in my case.
Finally, considering all the above, the last things to of course double-check are to: [1] Ensure you’ve got the correct fan curves and that your AIO pump is set to a correct profile for your workload, and [2] Ensure that your AIO is oriented with the fans to intake air, ideally.
It’s better to cool your CPU with intaked cool air, rather than exhausting hot air. If your case permits it, try to have the AIO radiator installed in an intake position with your two fans set to intake.

AMD’s current strat is to maximum the power of the cpu, pushing it to the thermal limit of 95c and attempting to use every last ounce of power it can.
I mitigate this, since I don’t think running that hot constantly is a good idea, by limiting the voltage to about 1.2v in Ryzen Master. Doesn’t impact performance, but keeps the temps down to around 60 when under strain.
According to AMD, it’s perfectly fine to run at up to 95c, though.
