Question Ryzen 5 3600, 80C idle temps ?

[gimmeoliver]

I'm new to custom PCs and don't know too much about them so I got a shop to build one for me at a decent price for my region, I had to take the PC with me on a plane ride but after booting it up, it seems to be just fine with no damage anywhere.
I did a 3dmark benchmark just to check if my numbers were normal and my Ryzen 5 3600 got a 5000~ish Timespy CPU score with its max temperature being 96C during the CPU test part. I thought this was weird so I monitored the temperatures using CPU-Z during normal 20-30% CPU usage and the temps were still high 70s, low 80s.

The customer service for the shop I got the PC built at assures me that this isn't a problem as long as the PC isn't stuttering or crashing but I'm still concerned. I've attached the components I got along with the screenshot I took of the temperatures during low CPU usage.
If anyone is willing to help me out with this, I would greatly appreciate it.
I can attach anymore details if they're needed.

If you are experiencing elevated cpu temps that would point me to the cpu cooler for a start at troubleshooting. I am not judging but an $8.00 cooler for your expensive pc worries me. I would check to make sure the cooler is still in good contact with the cpu and that the cooling paste is in good order. A repasting may be in order after moving it from one place to another.

likely a cooler either not properly installed , the thermal paste was either too little or not covering the entire thing, or even possibly someone didn't peel the plastic off coldplate and theres plastic insulating the cpu instead of transferring heat.


also the 3600's stock cooler is fine for it at stock. (3600 is a low power chip)

also doing a benchmark is going to get a lot warmer than any gaming load. (they are meant to push em harder than usual)

Timespy

The stock cooler isn't intended for loads like this. I doubt few would be surprised at what you experienced.

CPU-Z

As far as I know, Cpu-Z wakes up more cores than necessary, making operation look warmer than it is.
Ryzen Master doesn't do that, but it's not as user friendly, or so I've read.
I think hwinfo is in the clear though, as it gets recommended often for Ryzen cpus.

This is what I'm guessing as well after doing some research, I've ordered some thermal paste and am hoping that a reapply/just checking how the fan is installed will fix the problem.

I installed HWMonitor and while the temps seem a little lower they still seem a bit higher than other peoples' idle temps.

Also according to HWMonitor parts of my motherboard are hitting 100C, is this normal or is airflow in the entire case bad?

Everyone should not expect to have the same low load thermals due to factors like, differences in environment, components, and software settings.
More important is the CCD's temperature under a typical load, not a benchmark/stress test, which that little cooler wasn't built for. Check the temperature during what it is you have the PC for, be it a game, Youtube, or MS Word, etc...

No way to tell, as it has never been specified which motherboard sensor the reading comes from.

Use HWinfo 64, much more accurate with Ryzen. As for Ryzen Master, it shows "Effective temperature" of Cores and that means some medium temperature as if it was single core CPU.
Too bad Ryzen 3000 series doesn't show temps for each core separately like 5000 series do because it could be that only one (Most loaded) core is high but looks like it's whole CPU.
In any case, one measure of coolers effectiveness is temps at true idle (1-2% usage) which shouldn't be more than about 10c higher than ambient.

Using HWinfo, it seems like my temps are around 17C above my room's ambient (23C), so I guess it just comes down to the store having selected a bad CPU cooler?

Seems to hover around high 80s, low 90s, with some peaks at 95C when I was playing Diablo 4 with a Youtube video open in the background.

Better - not as extreme as the previous report, at least - and acceptable, since it's not sitting on 95C.


There are 2 ambients, which, BTW, influence how well a cooler does/doesn't: your room and the case, the latter which is always warmer. How much more depends on case design, hardware selection and configuration.
-That Segotep Lux-S has a solid front panel. Subjectively looks good, but in most cases is a hit to airflow, and thus cooling capability.
-The case didn't come with any fans, according to the shopping list, so you added 3... and those don't look very good, according to the paper specs. They're showcase fans; got bark, but not much bite.
-The Frost Castle 120K was likely a sidegrade compared to the stock Wraith cooler. Downdraft coolers aren't as effective in cases where they face solid side panels, as the main - if not, only source of air, is the case ambient... and if that's already warm, low and high load thermals likely won't look that good.


TL;DR: I speculate that air movement is lacking, and the front panel is restricting air intake quite a bit - the combo leading to high case ambient. Money was wasted by getting a 2nd downdraft cooler(Wraith was the first).

You can normally transport a computer in a car on smooth roads without any I'll effects if the CPU cooler is small (low mass).

If I ever have to shift my workstations, I'll remove the NH-D14 and NH-D15 heatsinks. Failure to observe this simple precaution could result in these coolers destroying the mobos.

If I was transporting any desktop computer on a plane, the first thing I'd do on arrival is check the cooler hasn't fallen off. Vibration levels in planes are different and the bump on landing could be enough to detach an air cooler or move a radiator.

I somewhat suspected that the case isn't being properly cooled since all the fans are mounted at the front and then are also covered by a big plastic shield. I'll try removing it and see if it helps with airflow.

Nothing seems damaged in the case from what I can tell, no weird noises or anything. I'm guessing that if the cooler was detached or damaged during shipping my temps would be even higher on idle.
