I have been doing a lot of thermal testing since I got my 5900X.
Ill go ahead and get my specs out of the way.
CPU: 5900X at stock settings. (PBO disabled)
CPU Cooler: NH-U14S (With the Noctua thermal compound that was supplied with the cooler.)
RAM: 32 GB (2x16GB) TridentZ Neo 3600 MHz
Motherboard: ROG Crosshair VIII Hero
Room temp: 70F/21C
Temps were recorded using Ryzen maser for the overall average temperature, and HWiNFO64 to get the readings from each CCX.
I have noticed that while playing some games, the temp for CCD 1 will spike up into the mid to upper 80s.
personally, I have only had MW2019/ CPD Warzone do this, but That's because I don't have any of the other games I have heard people reporting these temp spikes in. The other games were BFV and Red dead 2. I don't have these temp spikes in Halo MCC. From what I can figure out, The games that seem to be having these high temp spikes all have one thing in common. AVX workloads.
Im not 100% certain that this is the actual cause, and I'm also not certain that these temp spikes are entirely normal.
I have had a couple people tell me that the highest temp they get for CCD 1 in COD warzone is in the mid to low 70s.
What is everyone else seeing, and can I get an official answer from AMD?
Well it looks fine, you had 73C max temp. But I think there is more data needed for a proper evaluation.
You can try to answer the following questions:
- How long have you been gaming for? a good interval would be an hour or 2
- did you test it at 100% load? in your tests you had 55% max load. A good test would be a sustained 100% load for at least 10-20 mins.
I have run some test with Cinebench to test 100% load, this is my result with a room a little more cooler:
- Multi thread:
Is it okay ? Is it normal that the 5900x is always aroud 64° ?
Another problem is that my Kraken Z63 is always at 100% even when IDLE. Do you think replacing it by a Be quiet dark rock pro 4 will be good for a better ratio temp/noise ? Without harming to the CPU ?
@ItsAlex The forum seems to have mixed up my replies a little.
At 66C your cooling is performing great.
The CPU has a max temperature of 90C.
I'm not sure of the exact target temperature of that CPU but most of the Ryzen chips tend to run with a targeted temperature of around 70-75C
With regards to your earlier post of the Kraken running at 100% even when idle are you referring to the fan speed or the pump?
The pump should always run 100%.
You should be able to adjust the fan curve depending on temperatures.
