I have a custom built PC. I recently installed a new CPU cooling sink/fan (2 months ago). Last week, I am getting a CPU Fan error from my BIOS when booting. I can then hear and see the CPU fan clicking, though not yet spinning. I can see it make little jerking movements as if it wants to start. I see no cables or casing blocking it from spinning. If I give it the slightest touch to help it rotate it takes off and eventually reaches appropriate RPMs.
Is this just a dud of a fan? A power issue? Motherboard issue? Not sure what to try to resolve this. 5 minutes being turn on my CPU is at 29C and the fan is running at ~750pms. I can post new heat/rpm after running my normal games, videos, etc for a bit.
