Question High temperatures on Ryzen 9800X3D CPU with a Cooler Master ML360L AIO ?

[ksh.sharma]

Hi All,
I am seeing higher than expected temperatures on the 9800X3D with an AIO.
1. Cinebench R23.2 Multicore test, CPU temps hit 93 C in just a few mins,
2. During Hogwarts Legacy, Shader Cache rebuild, CPU temperature spikes to 95C, fans revving like a jet engine
3. Idle Temperature hovers around 53 ~ 55C,
I just recently got the AIO and the CPU, but am wondering if the AIO is damaged, or is it a case airflow issue.
Can you please suggest a solution ?

This is my system config:
- CPU: Ryzen 7 9800X3D installed with a Thermalright AM5 CPU holder, and TF7 thermal paste
- AIO: Cooler Master ML360L Top mounted, fans set to exhaust,
- AIO Pump connected to sys_fan header, set to 100%
- AIO Fans connected to CPU PWM Header
- Motherboard: Asus Prime B650M-R
- Case: Asus Prime AP201, with tempered glass cover (Installed Mesh in the front, and tempered glass on the rear)
- Other Fans: Rear mounted 120mm as intake , no bottom fans for the GPU
- GPU: Sapphire Radeon 9070XT
- RAM: 32 GB
- PSU Corsair RM1000e

Do the higher temperatures occur only when playing "Hogwarts Legacy, Shader Cache rebuild."?

What exactly is "Hogwarts Shader Cache rebuild"? Source?

Also update your post to include some photographs of your case, fans, and airflow directions.

It's when Hogwarts Legacy, a game prepares shaders in case of gpu update etc. This seems to be CPU intensive I suppose, attaching a picture for reference

In general the temperatures are around 60-80 while gaming at 1440 Ultra depending on the load.

Here's the Picture of the case with airflow marked in Red:

It would probably be a good idea to install two fans in the bottom. Also, is the power supply exhausting inside the case? And did you test it with all of the case panels removed?

Check its correctly seated with enough downward pressure and you did take the peel off if there was some didn’t you?

I plan on adding two Slim 120mm Arctic fans at the bottom as there is very little space and I can't fit full size 120mm/140mm fans due to the GPU.

The Power supply is mounted vertically so that it draws fresh air from the outside from the front grill and exhausts it upwards through the AIO rad.
The only other way is to mount it so that it draws warm air from inside the case. and exhausts upwards again, would that be better ?

Cinebench multicore test with all the panels removed results in about 1 -2 C lower temperatures, at best.

Hi, yes. I peeled of the plastic. Infact I replaced the default motherboard retention mechanism as the cpu back plate was bending due to the tension earlier.
I switched to the Thermalright CPU holder and repasted as well in hopes of getting better results, but still the same.

I may be all turned around here but something does not look right....

"fans at the bottom" ?

What about the GPU fans?

= = = =

This GPU?

GPU: Sapphire Radeon 9070XT [Pulse ?]

Saphhire Radeon 9070XT

Allow me to clarify, I meant the bottom case intake fans underneath the GPU, separate from the GPU fans of course.
Currently I have no bottom intake fans in the case because the GPU is taking up a lot of space, I plan to install slim 120mm as intakes.
And yes that's correct. it's the Saphhire Radeon 9070XT.

Perhaps as a last resort you might plan for a larger better ventilated case as your next purchase. There's really no solution to the power supply problem; I don't know what the designers were thinking when the decided it would be acceptable to exhaust the power supply inside the case. There has to be a larger case where you could use your cooler and gpu, have the power supply exhaust out the back, and have at least 7 full size NF-A12x25 fans (3 in front or on side, 3 on bottom and 1 rear).

You have no intake make sure to put fans in the bottom blowing towards the gpu.

Also check that Asus bios isn't using Asus boost method by default it always overvolts the CPU has issues with a 5900x. You can disable that and drop the voltage on the CPU. Leave CPU clocks on auto
