The Noctua NH D14's CPUID HW Monitor indicates the fan is spinning at an excessively fast rate.
The Noctua NH D14's CPUID HW Monitor indicates the fan is spinning at an excessively fast rate.
The CPUID HWMonitor shows fan speeds for two fans at the motherboard. One is connected to the CPU fan and the other to the CPU fan OPT. Temperatures are normal—22°C idle and up to 50°C during Prime95 testing with an i5 6600K CPU that hasn't been overclocked yet. What could explain this?
The BIOS displays half of the values. One is 1300, which is accurate, but the other is 550, which is significantly lower. The Noctua site mentions the expected speeds are 1200 and 1300.
It seems there was a mix-up, though both devices were initially set to Normal in BIOS. The one linked to the CPU OPT was running at half speed. Changing to full speed raises it to 1200. I was mistaken about that. Thanks!
