@iamso78,

Regarding the NZXT Kraken, it's possible to monitor and control pump speed, fans, and RGB lighting effects with liquidctl from Github, located here.

To install, we need to:
  • Install Xcode from Mac App Store
  • Install Homebrew, the package installer for macOS by typing the following in Terminal:
    Code: Select all
    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
  • Lastly, we intall liquidctl as follows in Terminal:
    Code: Select all
    brew tap jonasmalacofilho/liquidctl
    brew install liquidctl
When newer versions are released, we can update liquidctl simply by typing:
Code: Select all
brew upgrade liquidctl
Docs can be found here:

Congrats!
What software did you use to measure CPU temperature?
Were the fan/pump speeds measured or have you manually set them?

By prolonged sustained full load do you mean an actual stress test of both CPU and GPU? e.g. like power tests using OCCT on windows?

I’m just building my new system and doing some research first, I’ll appreciate answers!

@dmcyk,

I could not get AMD CPU temp, to my knowledge there are no Kext that would allow you to monitor via HWMonitor App in MacOS, please prove me wrong.
I follow these guides to try and get it working but still no CPU,

https://www.reddit.com/r/hackintosh/com ... 00x_fully/

Fan/Pump speeds can be read off and set using liquidctl, read up on their Github page.

I stress test it under Windows using same fan/pump profiles for MacOS/Linux in RealBench which stress test CPU & both my GPUs via OpenCL and in Blender full test.
Once stable I boot into MacOS load up the programs I use daily to try very hard and make it crash eg. constant 100% CPU usage by running muiltiple CPU intensively programs in the background whilst watching AppleTV+, likewise for Ubuntu.

Here are some 3950x Binning data

Please note my current [email protected] is not stable if stress test with Prime64 Small, but I can do [email protected] no problem, so your result may vary depending on the lottery and cooling solution.

I see, I'm still in process of gathering information, but I'll test those guide too.
Unfortunately liquidctl doesn't support my AIO from Fractal Design.

Thanks for the details. I was mostly intrigued by the temperature of your CPU during tests. When stress testing on Windows with 100% (on all cores) CPU and 100% GPU usage my 3900x with default setup, no overclocking/voltage tweaking reaches up to 85 degree Celsius.

I have run Prime95 Small thermal stress test the highest temp I seen from my [email protected] 1.2v all core stable for 1hr is 83 degree, 21 degree ambient, 36 degree water with 1800rpm fan and 2800rpm pump speed on Kraken x62.
