Question about temperature for 5950X device.
It handles high performance well and stays cool, though it tends to heat up regardless of the effort applied.
You are referring to a specific setup. In HWInfo64, the CPU temperature (Tctl/Tdie) remains consistently 20°C higher than ambient during idle, while individual CCDs (Tdie) show only about 10°C above ambient. The average CPU die temperature is around 15°C over ambient. I adjusted my focus to check true idle temperatures for the CPU—essentially measuring nothing else running except Windows and HWInfo64, with all other programs closed. Previously, I was checking temperatures while Firefox was active, possibly keeping some cores running. After letting the system sit until temperatures stabilized, I pressed the reset button on HWInfo64 and waited three minutes. Then I recorded readings using pressed plant fibers in a dark liquid applied via a stylus, avoiding any disturbance to the machine (similar to how ancient Egyptians logged data). Here are the results: CPU (Tctl/Tdie) – Min: 33.4°C Max: 34.8°C Avg: 34.0°C CPU Die (Average) – Min: 29.1°C Max: 31.3°C Avg: 29.6°C CCD1 (Tdie) – Min: 26.0°C Max: 42.0°C Avg: 27.5°C CCD2 (Tdie) – Min: 28.5°C Max: 38.3°C Avg: 30.8°C Core temperatures – Min: 24.0°C Max: 30.2°C Avg: 26.2°C It was quite chilly last night—57°F (14°C)—so I opened the windows. Clearly, it wasn’t that cold inside, but it dropped to 65°F (18°C). That means the CCDs were about 11°C above ambient, while the die was around 16°C higher. The CCDs stayed steady, whereas Tdie and die dropped a few degrees when Firefox was running. With Intel, I usually saw average temps in the low 20°C range during such cold spells. However, I’m not convinced Ryzen is the hotter model; it seems AMD’s readings differ from Intel’s.
That's an interesting test. I might have to do the same - I definitely am concerned given that I'm seeing 80C at a 3% load, but then again, I don't know if 100% load won't move the temperature much past 80C... (This is the package temperature read off of iCue, i'll be more thorough with HWInfo64 in a few moments here). I typically have a few things running when I was talking about "idle" temps - GoXLR App, Discord, Synapse, iCUE are the main ones. On my 9700K, idle temps under a 360AIO were maybe 5-10 over ambient, certainly not 40... Any recommendations here? Should I run your true idle test, and also run a load test to see what happens? If so, what numbers would be acceptable or indicate bad contact with the waterblock? I'm going to update my BIOS first, too - saw somewhere that that can sometimes fix random problems, so probably just a good idea overall.
Yeah... that's a lot for low load. I kept HWInfo64 running while scrolling through these forums and watching a few YouTube videos for about an hour. My average temperature spiked to 41.8°C, which is a 7°C jump. The peak reached 60.4°C, likely during a video. So the CPU hit about 40°C above ambient, though only briefly. Overall, it's around 20°C higher than normal for web browsing on Intel, but not as extreme as what you're experiencing now. I suspect there might be a cooling problem.
This behavior is typical for AMD stock CPUs. The voltage tends to rise as the workload decreases, allowing higher frequencies. To achieve those higher speeds, more voltage is needed, but when all cores are running at once, the frequency drops and voltage stabilizes near 1.1V. The maximum voltage I see is 1.487V and the average is 1.443V—since I’ve recently checked online, most cores are only active a few at a time, which can push up to 4.95GHz and demand more power.
There appears to be some inconsistency. I also have chrome tabs, Discord, and several 3D apps running while idle, yet it still stays under 65°C with air cooling. What are your typical temperatures? When you refresh the loop, you might want to ensure the thermal paste is evenly spread over the IHS.
I believe the thermal paste application wasn’t up to par, or I might have tightened the block too much. This was my first time using it, so I didn’t want to go overboard; maybe I went too far the other way. Either way, it seems like today will be a drain and rebuild session... Alright.
Gotcha, that makes sense. Going to let the BIOS update finish and see if anything is different, but its unlikely. Are you on air or liquid? If you're on liquid do you know the delta between your CPU temps and your fluid temps? I know it can obviously fluctuate when the CPU is loaded, but seeing the liquid + gpu (loaded) at 56C and the CPU at 85C (no load) just seems like too big a difference for good contact, unless AMD reports really differently
