Question 7800x3d temp spike

[Hix9]

Hey people,

I recently bought a 7800x3d and cooling it with an ek nucleus cr360 dark and on some occasions like launching a game it will spike to 80/83c, installing a game or a program the cpu can spike to 82/89C very berifly. The max temp of 89 is very rare though. Maybe I am too obsessed watching every details in hwinfo but sometimes the max cpu/thead fluctuate a lot it get pretty high and overall cpu stays relatively low most of the time except maybe in baldurs gate 3.

When running some benchmarks or stress tests like cinebench multicore, prime or aida64 it will never go past 80c

I have repasted it a few times and I am convinced I applied the paste correctly. I also have the latest chipset drivers and bios

Also when gaming it range between 58 and 75c, sometimes when playing wow it will hover around 60c and jump to 76/77c for a sec. Is this a normal behavior ? Is this going to cause issues or stuttering if it does that ? It is my first time with an amd cpu and i found it behave really differently than my previous intel builds

Maybe it is your fan curves, depends on what temps are set for it to ramp up and how quickly they are set to ramp up and down.
The fans changing speed can make a huge difference in the temps which is why you want to set them to a fixed rate when you are doing testing.

The temp of cpu in general does not matter as long as you do not hit the point where the cpu drops its clocks to prevent overheating. As long as you are below this point it really doesn't matter what the exact number you have is.

I do not know the point a 7800x3d is set to thermal throttle. hwinfo seems to have a this information for most cpu and will tell you if the chip it hitting a thermal limit.

Well it is an AIO so i think the fact that the fans instantly ramp up won't make a big difference and the throttle is in fact 89c. The thermal throttle only happened very rarely while a program was installing and unpacking from a repack

Does the pump run at 100% all the time.

Generally cinebench will be much more brutal on any cooling than normal traffic. Most stuff is going to spike just a single core and that will not cause far less temperature increase.

Actually I did turn down the pump to 75%

I'm aware it's an oldish thread, but I feel I should chime in, seeing as I upgraded to a much angrier processor with the CR360. With the stock fan curve and stock CPU, my 14900K would thermal throttle after about 20 minutes of playing cyberpunk. At some point, you need to ask yourself if you're willing to sacrifice silence in favor of performance.

I have since set up an aggressive fan curve that ramps all fans to max rpm at 55C until I'm able to de-lid this monster. After doing so, I'm no longer reaching TJMAX in CP2077. I always run my pumps at a flat 100%.

This was after a 4hr CP2077 session:

My timespy temps dropped by 10C too. Overall, I'm pleased that I chose this over the Arctic Freezer 420.

For whatever reason, I can't edit my post, but I just wanted to note that after transferring my PC to another room, my temps haven't risen above 91c while playing CP2077. Overall, I'm quite pleased that I won't have to undervolt. Well done, EK. Well done!
