[Thermaltake Floering 360 only operating at half speed, CPU overheating]

Hi

I have this AIO: https://www.thermaltake.com/products-model.aspx?id=C_00003122

My CPU is getting very hot at 90c

I can see in BIOS the pump is always running at 1800rpm. I also used HWInfo software in windows and even when stress testing the CPU at 100% load, the pump is always at 1800rpm

The product is advertised as 3600rpm

How do I make it work at 3600rpm so my CPU doesn't get to 90c??
