So how hot can a CPU get? Generally, your processor shouldn’t run at anything greater than 75°C/167°F.

I assume your talking about something like a d15?

I just run CPUZ stress test. It heats it up quickly.
NOCTUA NH-D15 chromax.Black, 140mm Dual-Tower CPU Cooler
Threads leaning toward 80C being ok(I hope).
Seems like my low 80s C may be normal for a 3950x. I'm just not use to any thing running this hot.
Still reading up on it.
Thanks

Because of how dense the processor die's are, they are going to run hot. I'll be honest it does seem a bit warm for stock. I run about 72 on cpu-z on my 3900x. D15 single fan setup.
Fan curves can account for some of it though.

If it is a fixable seating problem then it should be very obvious if I finally get it right.

My i7-3770 was going higher than 80 degrees celsius in stress testing the first time I booted it up. After reseating the heatsink, the difference was like night and day. I don't remember exactly but I think the temperature dropped like 20-25 degrees.

EDIT... Just realized I don't know your ambient temp. Mine is 28C.
Thank you, your results really bring my temps into question as in "my setup has a problem."
Because from what I've seen online, due to the extreme binning of the 3950x chips it uses LESS power then your 3900x.
So with a CPUZ Stress Test an "on average" higher power 3900x chip hits 72C with a single fan
while both of us are on D15s and my 3950x with 2000 to 3000 RPM fans hits 82C.
Yep, I clearly have a problem here...Thanks again!
I really don't want to get into lapping. Saw a Gamer Nexus video where his very expensive really high core cpu "just" had a bad heat spreader.
He took it to a famous overclocker (Vince?) and had it lapped flat on a spinning metal device...big improvement in temps!
Think I'm going play with reseating the heatsink a few more times.

I'm not sure what this is..."Stock of avx2 beta?" ?

At your ambient it seems in line. My ambient is about 22c.
Also I covered the entire heat spreader, since I didn't know where the dies were.

Furthermore, Ryzen 3000 CPUs are using the rated temperature headroom (up to 95°C) quite aggressively in order to reach higher boost clocks. As a result, it is absolutely no problem and not alarming if the processor runs into this temperature limit. The clock speed and supply voltage will be adjusted automatically by the processor itself in order to remain within AMD’s specifications and to prevent overheating.
Due to the higher heat density, higher thermal limits and more aggressive boost clock usage, it is perfectly normal that Ryzen 3000 CPUs are reaching higher temperatures than previous generation Ryzen CPUs with the same TDP rating. Higher CPU temperatures are normal for Ryzen 3000 processors and not a sign of that there is anything wrong with the CPU cooler.

I'm not talking about failure due to overheating. I'm talking about the gradual deterioration of silicon circuits due to consistently high operating temperatures. Noctua can link to an AMD FAQ about the high temperatures and put the onus on AMD but saying these things without backing them up from an official source is just inviting legal trouble.
just brew it! wrote:I disagree. If the CPU is getting hot enough that it is deteriorating to the point where it is not meeting specs, that IS on AMD and their thermal throttling implementation. The whole point of Precision Boost is that the CPU is supposed to ramp up clocks (and power budget) based on available cooling performance.
OTOH, if the CPU is still meeting specs then there's no grounds for "legal trouble".

As per that review, AMD recommends a liquid cooler. And even then they got 74C at 24C ambient. So AMD is gonna simply bow out by saying, "Hey, we didn't tell you to cool this beast THAT way!". And I hate to sound anal, but Noctua is misleading its customers just to sell them their product.

He got his temps down to 60C at 100%.

You don't really need to since your temps are already within reasonable range but it doesn't hurt to try, does it?

There's nothing to gain. You're making him worry about a complete non-issue.
