My Ryzen 5 2600 at stock speeds reaches 78C under full Prime95 load. Is this normal? Seems a bit high. I am using the stock AMD Wraith Stealth Cooler.
 
It'll perhaps be XFR boosting to 4.1 or so?? more volts when it does that so higher temps. I may be wrong though.
 
Also Prime brutal on your CPU. It doesn't reflect day to day use. Did you use the stock thermal paste with the cooler or some of your own?

I think its normal AMD CPU runs hotter than intel. In this review they mention temps of 74C with the stock cooler in a blend stress test...

I am getting 78C in a Small FFT test.

That's perhaps down to you don't normally use the stock INTEL cooler with Intel like you can with AMD. Usually an aftermarket cooler with INTEL hence the better temps over AMD stock cooler. Stick a decent cooler on Ryzen and it'll match or beat Intel for temps.
 
The stock AMD cooler with the 2600 is good but not amazing - if you have any kind of frequency boosting over stock going on and/or I think just having fairly high MHz RAM/XMP loaded up increases it a little as well then getting to around 78C with torture tests isn't unusual I think. You shouldn't see anything like that at idle or in normal kind of loads.

EDIT: The safe "max" working temperature for Ryzen CPUs is around 80-85C without any significant impact on their lifespan - the absolute max is a little over 90C (usually around 95C) at which point you'd see some minor degradation of the lifespan of the CPU if it was constantly ran at that - above ~95C you could potentially see sudden CPU death or degredation at any random point if ran constantly. So 78C is within acceptable limits though I wouldn't recommend running one at that temperature constantly as there isn't a huge amount of overhead - but normally you'd need to use torture tests to get there it would be more concerning if that was what you were hitting under normal gaming, etc. loads.

Just used the TIM that's comes on the brand new cooler.

You need to scrape off the stock tim and replace it with something like MX-2 or 4. Also, the Stealth is smaller than the Spire cooler that came with the R5 1600. AMD cheap out on the R5 this time. Sad.

Im using a T4 cpu cooler with push/pull on my 2700 and it does the job.

my 2600 (4.1ghz @1.35v) is custom watercooled, playing shadow of the tomb reaches around 45-48C, but when using prime it jumps to around 62C
 
Not really concerned about the temps just wondered if it was normal with the stock cooler. I used to run temps of 79c with my old i5-2500k @ 4.3 and that was fine, that was with a decent Akasa Venom air cooler. If these kind of temps with the stock cooler were in any way dangerous then AMD would have supplied a better cooler.

It just seemed a bit higher then what I expected with the stock cooler.
 
If it can keep it at a safe temperature under the most extreme of circumstances, why would they need to supply anything better?

Compared to Wingz's temp . . . yes, it is normal.

I've had a look at the CPU fan speed in the BIOS, in smart fan mode the fan only ramps up to 100% at 85C so 78C under 100% load isn't extreme.

Is this adjustable?

If so I would put the 100% lower at 70C. This may be slightly noisier occasionally but possibly anticipate and lower the upper end of the temperatures reached.

Yes it is adjustable, I just set the CPU fan to always full on and under Prime95 the full load temps reached a max of 70C compared to 78C with the default fan settings, I think I will set it to come on 100% at 70C and above.
 
Set the CPU fan to come on 100% at 70C and now it reaches a max of 74C but hangs around 73C mostly. A little higher than when I had the CPU fan always at 100% but better than before where it reached 78C. The CPU fan isn't that loud anyway, my graphics card fan is louder.

Yeah, the fan is always playing catch up. The CPU frequency (and temp) reacts in nanoseconds and the fan can only respond in a much larger time interval due to the inertia of its rotational mass and air pressure. Its something else to play with anyway, a bit of a result.
 
Left it running Prime95 small fft for about 40 minutes, with HWinfo it reached a max temp of 74.8C still a bit better than the 78C I achieved after about 15 minutes which would have probably risen to 80C after the same amount of time.
