Question Cinebench acting weird with i7-13700k temps ?


Dec 26, 2020

I built myself a PC a few days ago and after installing Windows and all the drivers I played some games to see the performance(WoW, 1440p and max settings). After that I decided to undervolt my CPU to get some lower temps.
I went in to the BIOS(ASUS ROG Strix Z790-F Gaming WIFI ) and did the following tweaks:

Current ASUS MultiCorre Enhancement - Disabled - Enforce All Limits
Maximum CPU Core Temp - set to 95c
Long Duration Package Power Limit - 125
Short Duration Package Limit - 253
Global Core SVID Voltages - Adaptive Mode
-Offset mode sign - Negative
-Offset Voltage - 0,1(I went for 0,05 and tried out some Wow for 3-4 hours without any problem).

My temps right now is Idling between 30-33c and on WoW it's around 55-60c

NOW for the weird part. I tried cinebench and after 40 sec my package temps went from 86c to 66c(none of the cores reached 95c) for the whole 9min left of the test. I tried several times and the CPU acted the same.
I don't understand what's happening, I'm not home right now but could it be the Power Plan setting in Windows? I know it's set to Balanced by default. Could that be the culprit?

My Parts:
ASUS ROG Strix Z790-F Gaming WIFI
Samsung 980 PRO M.2 NVMe SSD 2TB
Corsair 32GB (2x16GB) DDR5 5600MHz CL36 Vengean
Intel Core i7 13700K 3.4 GHz 54MB
Noctua NH-D15 chromax Black
Noctua NF-A12x25 PWM Chromax Black x3
Gigabyte GeForce RTX 4070 Ti 12GB AORUS MASTER
Corsair 4000D Airflow Black
Corsair HX1000i 1000W
OS: Windows 11 PRO

The CineBench all core is a very extreme test. It's a good tool to see how good your cooling is at absolute maximum load for an extended duration.

There is nothing wrong with your D-15. The 13700/13900 are extremely power hungry cpu's when loaded. If you want lower temps with CineBench water cooling is the better option for your cpu.

For general users and gamers, your pc will rarely see all cores loaded for an extended duration.

I agree, I got the air cooled solution because I prefer it and in most casses I won't use CPU heavy tasks. The PC is mostly for gaming.

I just happen to use Cinebench to check how stable the system(CPU) is with my new tweaks in BIOS and do not understand why my CPU reaches high temps for 40-45sec, goes down to 60c and stays there for the entire test (10min test).

I suspect Windows 11 Power plan settings or Windows 22H2 update(because I downloaded Cinebench from Microsoft store and in the update it says something about Smart app control -might be farfetched. I will look in to it when I get home).
