the temps of my 3950x seem too high. Note that this is my first build. All temps are measured by Ryzen Master.
I get +/- 50C in idle.
While playing demanding games (Outer Worlds, PUBG, Rust), I get 60-70C if I lock my fps under 100. If my fps go higher than 100, I get 75C.
While rendering a simple model in Blender, I get 85C and my CPU is under full load.
ROG STRIX RTX 2080Ti 11G OC
AMD Ryzen 3950x + Noctua NT-H2
Corsair Vengeance Pro 2 x 16 DDR4 3200MHz
NZXT Kraken X72 360mm
The AIO 3 pins connector is plugged on CPU-Fan
I only use 8 pins connector for CPU-Power
Kraken's fans are at 100%
I'm not at home, I will post a screenshot of Ryzen Master if needed.
Solved! Go to Solution.
OKAY ! I fixed it. I get less than 60C at 100% PPT
I did reapply my thermal paste. Instead of making a big dot in the middle of my CPU, I made a cross + I connected my pump on AIO header instead of CPU_FAN + I updated the BIOS
Big thanks to the people who helped me on this thread
How is the boosting behavior of the CPU? Does it run full blast?
Have you checked if the water pump is running? and if so what does the bios says about the RPM of the pump?
The pump needs to be at 100% always.
Maybe you're mobo is pumping unnecessary high voltage in the chip, did you set any overclocking settings in the mobo or is it pretty default and standard?
Hello, I will give more details later by posting a screenshot of Ryzen Master.
The pump seems to be working properly. I set it at 100%.
I didn't try to overclock anything. I did just change the frequency of the DRAM and did some modifications to the fan speed before restoring defaults settings.
I don't have experience with this board or the specific sku but i have noticed that PBO on some boards pushes the cpu always to the max temp with more voltage and frequency.
Probably if you turn down the fans and ease in the cooling the temps would stay the same, just the cpu would boost a little, little bit less than before.
You can also check how you're score in a benchmark like cinebench and compare to others to check if you're performing above standard or below standard.
Also you could try disabling PBO in bios, if temps are low and well under control you know its the PBO algorithm that pushes the cpu as far as it can go under the cooling situation
icreeplacrepe, please post a screenshot of Ryzen Master (RM) - simply drag-n-drop the image into your reply. What does this mean: "I only use 8 pins connector for CPU-Power"? Please post your OS version and power supply.
The board has an 8 pin + 4 pin for cpu power.
In theory a 8 pin should be more than enough, as long as the board is not crammed full with immense amount of stuff and overclocking till the max.

Ryzen1988 has the correct answer to your question about the 8 pins connector
Today, I don't know how, my CPU fans are at 2700 RPM so temps are not as high as this last week. They normaly are at 2000 RPM. Can someone tell me how to configure RPM?
I checked temps while rendering a basic model on Blender and the max temp was 82C.
Thanks ryzen1988, as you like. I have always figured that the MB designer did not put them there just to increase the price and I populate all power connections. Enjoy,
icreeplacrepe, I do not mess with my fan speeds. How it works is very dependent on the MB BIOS, so I suggest you post on your MB forum. As for me, I have a big case (Full Tower), run big, slow fans and run all fans and my pump on 12 Volts straight from the power supply (Full Speed). The system is surprisingly quiet. Thanks for the RM shot. The fact that VTT MEM is zero (0) tells me that someone or something is messing around in your BIOS. I suspect the MB software. Enjoy, John.
