Question Ryzen 7 9800X3D has very high temps at idle ?

[marektmv]

Not cpu usage, the actual applications and executables running, and/or running in the background, are going to cause temperature spikes. No cooler can keep up with how fast they can happen. If you're sitting there monitoring thermals, or leaving the software running in the background, it's going to look like something's wrong, when there isn't.


Noctua fans have arrows on their frame depicting the direction the fan spins, as well as which side the air exits from. I can't see the arrows in the image, 'cause it's too dark. I also can't see the 4 arms of the frame which usually indicate the backside of the fan.
So, with those points in mind, you can confirm that those fans are aimed to move air from right to left?

How can i check that applications?

i had same feeling with temps like that but the new gen Processors are supposed to run that hot.
70-80 nothing wrong. After two years i do not worrie playing 4 hours games @80-90 degree.

What is the optimal temperature for Ryzen 7?

These processors are designed to work up to 105°C. You should start being worried if the temperature is consistently approaching this value (above 95°C or so) but around 85°C sustained is nothing to worry about.10 Sept 2022

Oh, that? Task Manager/processes.

Fans are facing the correct direction.

i havent seen anyone getting more than 60-65 in games, i have same in idle. At 85 i can hear fans from next room so thats not acceptable. I tried to set fan curve to smaller % to reduce noise but temps got even higher . So in conclusion it’s noisy heater right now.

I checked and searched online most of them but didn’t find anything flagged as not Normal.

Well, after all that, I don't think there's anything out of the ordinary, and you're reacting to the waking up from sleep core spikes that every cpu goes through.

here a my Temps running 12 hours now.
Since i undervolt the Cpu it peaks around 5-10 degree less.
Never had any problems and AMD statement are clear Ryzens are running on 80 with nothing to worry about.

I have a 9800X3D and 60c at idle is not normal. Mine barely reaches that temp while gaming (doesn't even reach 50c in CPU-light games like FF7 Rebirth). I read a thread a couple of years ago about a similar problem with an AM5 CPU and turned out that the wrong brackets were installed on the board, so the cooler could not make good contact with the CPU. The guy ordered the AM5 compatible set of brackets and the temp instantly went down to normal.

If you always get this high idle temp, even when the case is open, with two different coolers and without overclocking, then it could be that the contact between the CPU and the cooler isn't good enough.

By the way, the 9800X3D is designed to throttled down at 95c to prevent it to get hotter than that. If you stay well below that, like 80c, then you should be ok. But indeed, 80 while gaming is not normal for this CPU. It can reach pretty high temp (90-92) when all the cores are 100% loaded, for example during a Cinebench run, but in gaming it doesn't run hot at all.
