2700x 95 degrees while encoding with handbrake

Yesterday i was encoding a video and out of curiosity checked cpu's temperatures while doing so. I'm running this cpu without overclock and with stock wraith prism cooler xfr&pbo enabled.

Encoding in handbrake utilizes all cores and threads at 100% which is normal and expected but one thing i didn't expect is when i launched hwinfo and took a look at cpu's tctl i saw 95 degrees. That was the first time i saw such high temperature on this cpu. I think it is related to 100% utilization on all cores and threads as for example while gaming it doesn't reach more than 70 degrees.

Anyone else having similar observations?
 
Some motherboards are known to pump too many volts into the CPU, like Asus Prime Pro.

Download this https://www.cpuid.com/downloads/hwmonitor/hwmonitor_1.39.exe

and keep your eye on the CPU volts, it should not go above 1.45v, even that's a bit high.

Tdie is the correct temperature, which is 10C lower (at least in hwinfo).

Prism is actually a fairly good cooler (if you don't mind the noise), but if the airflow in the case can't supply it with cool air, it'll warm up (just as any other cooler would).

Do you have any temp sensors inside your case? Just for air temps inside? Which case, which fans, how are they setup etc?
 
Well, cpu cooler is waaay more quiet than my gpu, imo it is very silent as even under heavy load i do not hear it.
No, i do not think i have any extra sensors in case. Case is some basic crap, i keep it with a side opened.
 
I have never used AMD's Ryzen Box coolers, as far as box coolers go they are apparently very good, but they are still just a box cooler, not as good as even a £30 aftermarket cooler.

If its quiet even under heavy load i would question if the fan is actually spinning up properly, if the BIOS doesn't have it stuck in some "Quiet Mode" a 100+ watt CPU should be putting that cooler to the test so its fan should be running at high speed under high load, 3000 RPM, that should make a noise even if its not overly loud it should still sound like a fan wring away at high speed.
 
Well, at 100% fan speed i would probably hear it. I keep it on stock and never heard it at all, even at full load of cpu wraith prism's fan is really silent. The only fan i hear in my pc is on gpu while gaming. On cpu fan definitely never goes to 100% of its speed.

It probably will never actually go to 100% but 80% yes.

I would use HWMonitor to keep an eye on the Fan RPM, if its not going at least 3000 RPM at 80+c its probably not right and you may need to fiddle with the BIOS, also keep an eye on the volts as i explained earlier.

How far away are you from the case if you can hear it? Or is it not spinning up too fast. Maybe let it go to 100% when temps hit that sort of high?

I don't think a £30 cooler would do much better to be honest, I swapped mine out due to the noise, but it was pretty good temp wise. £40+ certainly (not much point in going over £55ish).

It became a bit louder on that load but i would call it slightly audible, definitely nothing even close to loud or annoying.

That's 85c, the 95c reading is wrong, its a bug or something, can't remember exactly what that's all about....

Your Fan RMPs at 2300 do look low, play about with the BIOS, maybe turn Cool And Quiet off? to get those RPMs up a bit.

I don't know what the long term temperature safe limit is, exactly, but i think its around 75c, i would not run it long term above that, or maybe if you can get the "Package Node" in HWMonitor under 80c, closer to 75 you should be alright long term.
The volts look 'ok' peaked at 1.44v, if you know how to adjust volts try setting them so they peak at 1.39v, that will shave a couple degrees off the temps.

@Unseul yeah probably true.
 
My head is in range 0,5-1m from case.

I'm not worried in long term as such load i'm getting only while video encoding and this is not something i do few times per day but more like once per few days or even more rare and with power of this cpu encoding doesn't take long.
 
Try setting a negative vcore offset. My 2700X was able to happily run at stock settings with a -0.1V offset, which seems pretty common based on what I've read and had a positive impact on my temperatures. You can always start at -0.05V or so and work your way upwards to find the stability point.

AMD regularly pump too much voltage into their products, which is why people have so much success undervolting their GPUs too.

Asrock x470 taichi ultimate here and this mobo by default has offset set to -100mV.

That seems very unlikely. I've never encountered a motherboard that undervolts by default on any platform, ever. It'd make absolutely no sense, because some chips just won't be able to do it.
 
Also i took a look now into fan settings in bios and there are 4 or 5 profiles. I'm running default one which is named "standard", for a moment i enabled "performance mode" and this one even while in bios already was noticeably audible to say the least. I will keep it on standard.
