straight to the point, i have a H150i Pro liquid cooler and a i9-9900k and it struggles to get idle (1-5%) under 40 degrees C i'm not 100% sure but to me that's a bit high for idle, playing gta 5 it only gets to about 30% - 40% usage and about 60 degrees C all 3 fans are on 1500RPM and the pump is 2700ish RPM. the case is the fractal define R6 and the Rad is mounted on the top with the fans pushing air out the top and the thermal paste is stock. i have heard things about the CPU lids not being flat preventing bad contact, and in order to rectify i would have to sand it, that is my worst case scenario. any other thoughts? thanks
