goldern Posted June 6, 2020 Share Posted June 6, 2020 I have a system with an overclocked I9 9900k at 5ghz all cores, 1.3v vCore and an overclocked GTX 1060, +200 MHz core clock and +600 MHZ memory clock. But even at 100% CPU and GPU utilization in synthetic benchmarks, the SF750 fan doesn't even move. Is there something wrong with my power supply? It remains most of the time the same temperature as the CPU (40ºC - 60ºC) and even when it's at 70ºC-80ºC the fan remains offline. Link to comment Share on other sites More sharing options...

Or are you using a FLIR or something? Link to comment Share on other sites More sharing options...
Net7 Posted June 7, 2020 Share Posted June 7, 2020 Same issue here, Ryzen 3950x and Radeon 5700XT. 48c idle outer temp 54-58c idle inner temp 55-60c load outer temp 65-75c load inner temp I will note that the fan makes an effort to spin on system power on, but i haven't seen it on past that point and it doesnt really fully spin up, just a few revolutions then done Temp checking done with IR thermometer, in addition to its probe attachment and been tested against other temperature tools for 3-5f range of accuracy at tested range.
