Question How hot does your AMD Ryzen 3700X/3900X run?

[jon96789]

I have read that many people with the latest Ryzen CPUs are finding that their CPUs are running a lot hotter than expected... Some people think that the AMD chips should not be running more than 75 degrees but is that what people are getting? I am polling to see how your system is doing to determine what people are getting... If you are using a non-stock air or AIO liquid cooler, please add that to your comments... Under load would be running Cinebench 20 or doing video encoding... Gaming does not normally stress the CPU as much as rendering, encoding or test apps...

FYI... I have a AMD Ryzen 3900X with a MSi MPG Game Pro Carbon Wi-Fi with 32GB RAM and a MSi RTX2070 Gaming Graphics card. My CPU is running under Windows Balanced mode (with the CPU capped at 99% or 3723MHz) and idles at 42 degrees and peaks at 75 degrees. If the CPU is set to 100% (or unrestricted mode), it idles at 52 degrees and peaks at 90 degrees under load. The highest CPU speed is 4423 MHz.

My 3700x idles at 32 to 34c and maxes out at 60-62c after hours of gaming.
I encoded a few movies yesterday and it never got over 60c.
I have an Arctic 33 eSports Edition dual fan cooler.
My ambient (room) temperature is 22-23c.
And I have very good case airflow.
See my signature for my full specs.
Those temperatures are with PBO enabled and the Ryzen Balanced Power Plan set to 100% max and 10% min.
It sounds like you either have a very high ambient temperature or your case cooling is horrible.

30-35c idle and I haven't reached over 75c under load with 3900x using cryorig r1 ultimate. I just think people expect the out of box cooler to be amazing and are surprised when they hit 90c with it

I just upgraded my Ryzen System. I have had all three generation on the same system board and case and fans.
Node 202 SFF
Gigabyte B350 Wifi
Noctua LP color with Stock Ryzen fan (it touches the top vent to the outside sucking in cool air)
Ryzen R7 1700
Ryzen R7 2700
Ryzen R7 3700x... all 65W parts.

Running H265 video encoding the 2700 on this set up stock settings averaged 127F all day with a quite fan.
Upgraded to the 3700x (after all updates) and as soon as I video encode it shoots up to 202F and stays there. NOT ACCEPTABLE. Reviews all say Ryzen 3000 needs better cooling, but if they are claiming both are 65W parts, they should cool similarly with same cooling set ups! This new chip idles hotter than the previous one does at 100% load. Not why I got the 65W part!
Just like to add: The exhaust air coming off of the 2700 was warmer than the exhaust coming off of the 3700x.

Fractal Define R5
Strix X570-E Gaming
Thermal Grizzly Kryonaut
NH-D15 (889 RPM)
5 x Venturi HF-14
My case fans are set to the maximum of 3 settings (i.e. 1 x 889 RPM, 2 x 1118 RPM, 2 x 1140 RPM).
AMD Ryzen Balanced power plan
Ambient room temperature is likely anywhere between 22-23*C.

1 x Aorus NVME
2 x 16GB of Ripjaws V Series 3600MHz


ABSOLUTE IDLE
36C, but sporadically jumps to mid 40s (45-46C).

UNDER LIGHT LOAD (i.e. browser windows open with many tabs, some light programs running, etc)
Jumps very erratically between low 40s to high 50s and much less frequently low to mid 60s.

The erratic nature of the temps has me wondering if this might be due to using too little thermal paste? Thermal Grizzly emphasized spreading the paste as thin as possible, but, after watching an LTT video, it seems it's better to have too much rather than too little paste. Will probably reapply it sometime in the future.

GAMING (i.e. CoD: MW at max settings with Ray Tracing disabled)
The highest peak so far has been 79*C.

Notably, 4541MHz seems to be the highest core speed I've been able to obtain from the latest BIOS (v. 1405 from 19/11/26). Obviously I haven't tried to overclock it.

I've had both an R5 3600 and (currently using) R9 3950x - neither ran / running hot.

 

[logainofhades]

I was getting 62c max, according to HW monitor, after an hour of gaming, with my 3700x, and a cryorig A40.

I've never gone above the mid 70s with my Ryzen 9 3900X and aftermarket cooler.
