Question Why can't the Arctic Liquid Freezer II 360mm cool my i5-13600k?

[eyaya]

Hello!

So a few days ago I ordered my new shiny Arctic Freezer II 360mm AIO and mounted it into my Corsair 4000x. The first thing I did after installation was obviously stress testing my cpu and monitoring the temps.
It sadly peaked to 100C° after 3-5 seconds. After some searches on Google I was convinced that I just put too little of the included MX5 thermal paste on the cpu. In the end I nearly put half the tube (~.4g) on the cpu. It still thermal throttled. To be sure that HW-Monitor was reading a right temp and frequency I usedHW-Info and XTU to confirm the temps. In Cinebench R2 I only got around 20k - 21k points instead of 23k. Important to notice is that I kept my case completely open during the test.

Things I tried: Remounting, putting more thermalpaste on
I did peel off the plastic on the coldplate.

My specs relating to this topic:
i5-13600k (PL1 and PL2 were automatically adjusted to 180W and 253W from the stock mainboard settings)
Asrock H670 Steel Legend (no changes to settings relating CPU and Fanspeed)
Corsair 4000x (Stresstest with opened front and side panel)
Thanks for your help!

Which header on the motherboard is the pump block/fan controller tethered to? Speaking of motherboard's, what BIOS version are you on for the motherboard?

One more thing about the PSU/PCIe cable, if they are what seems, to me, like you're running a daisychain, please work with a standalone connector for the PCIe. Which GPU are you working with?

It is connected to the cpu1 header. The fans are spinning with the advertised 1800rpm while running Cinebench. I just updated to the latest bios a few days ago, because I had problems with my ram.. Now it works fine.
I sadly made the mistake buying the cheap Corsair CX750M, because I was on a low budget for the psu after buying the gpu. I got an Aorus Master rtx 3080 10G in rev 1 (only 2 connectors for power on the gpu). Oh, and the powersupply is really loud too....
