Default iCUE prevents i9 9900K turbo boost

Hi,

I'm experiencing this wierd issue on my freshly installed PC:
When iCUE is running, none of my i9 9900K's 8 cores will ever boost above 4700Mhz, but immediately after closing iCUE the cores start reaching their full boost potential of 5000mhz. Starting iCUE again drops the max boost to 4700Mhz again.

Cinebench scores are affected both on single cores and full CPU scores.

My case fans (3xML140 RGB) are connected to Corsair commander. The AIO fans are connected to the H115i pump. (both RGB and fan headers)

Cinebench R15 without iCUE running
Single Core Score: 213
Full CPU Score: 2027

Cinebench R15 with iCUE running:
Single Core Score: 199
Full CPU Score: 1864

Any ideas?

Software:
Windows 10 v17763
iCUE v3.10.125
CPUID HWMonitor v1.38.0
