Hi Friends,
I've recently upgraded my computer to a i9-10850K and would really like your thoughts and opinions around some thermal issues I've been having...
For reference I've drawn up my current build and airflow:
Issue:
When I stress test this computer using CineBench or similar with an all core stress test, all the cores temp go to 100C straight away and stays there. What I've noticed:
I've used this cooling rig for mutliple CPUs now:
What I've tried:
If any of you have had similar experience or could shed some light that would be great. I just want to be certain about what the problem is before I either return it, or invest in some more heavy duty cooling...
Again really appreciate your help.
Cheers,
Morgan
I've recently upgraded my computer to a i9-10850K and would really like your thoughts and opinions around some thermal issues I've been having...
For reference I've drawn up my current build and airflow:
Component | Part |
---|---|
CPU | Intel Core i9-10850K |
CPU Cooler | Corsair Hydro H100i GTX (240mm Radiator) + 2 120mm Noctua F-12 Industrial 3000RPM fans in push configuration |
Case | Phanteks Enthoo Evolv ITX |
Front Intake Fan | 200mm Phanteks PH-F200SP Fan |
GPU | EVGA Hybrid RTX 2080Ti (120mm Radiator) + 12 120mm Noctua F-12 Industrial 3000RPM in pull configuration |
Exhaust Fan | Noctua NF-A14 140mm Fan |
Issue:
When I stress test this computer using CineBench or similar with an all core stress test, all the cores temp go to 100C straight away and stays there. What I've noticed:
State | Temp | Frequency | Voltage | Power | Questions |
---|---|---|---|---|---|
Idle (Windows 10) - 10% CPU utilisation max | 55C (+28C ambient) | 4.4GHz - 4.8GHz | 1.3V -1.4V | 29W - 50W | Weird considering base clock is supposed to be 3.6GHz so no idea why its always clocked so high? |
Intel XTU Bench | max 90C (+63C ambient) | 4.8GHz | 1.4V | 50W - 200W | Is 3818 Marks considerably low for this bench? |
Intel XTU Stress | max 100C (+73C ambient) | 4.8GHz (4.4 throttled) | ~1.36V | 125W - 200W | Starts off at 4.8GHz 200W then after around 20 secs it thermal throttles to bring the temp down. Then soon after it starts power throttling keeping the power usage at around 125W under TDP. When power throttled, temps generally floated around 84C. Is this normal? |
CineBench All Core Stress Test - 100% CPU utilisation | max 100C (+73C ambient) | 4.8GHz (4.4 throttled) | ~1.36V | 125W - 200W | Same as above. |
Gaming (Cyberpunk 2077) - 33% -66% | max 100C (+73C ambient) | 4.8GHz | ~1.36V | 160W | Seems to keep running at 100C which worries me. It doesnt power throttle either like the benchmarks |
I've used this cooling rig for mutliple CPUs now:
- i7-4960X (130W TDP)
- i7-6700K (91W TDP)
- i7-8700K (95W TDP)
What I've tried:
- Replacing thermal paste in case it didn't spread well... Using the Noctua NH-1 paste.
- Changing the CPU fans to pull config to pull in cold air instead
- Running the CPU Radiator outside of case in push configuration.
- Spinning the case fans to max rpm (not ideal)
- Undervolting the CPU by 0.05V (didn't help) too unstable when more undervolting occurred
- Turned off MCE (saw it on a post in some other forum)
- Disabling short term boost to keep TDP under 125W. (didn't seem to work, kept going over 125 W anyway)
If any of you have had similar experience or could shed some light that would be great. I just want to be certain about what the problem is before I either return it, or invest in some more heavy duty cooling...
Again really appreciate your help.

Morgan
