I started up my PC this afternoon and got a warning message from the BIOS about a fan error. With SpeedFan it looks like the CPU fan is only running at 700 RPM, occasionally dropping to the 400's. Even under load the fan never goes any faster. ASUS Q-fan is disabled so I'm assuming it should always be running at max.
The fan looks and sounds like it's rattling around. Is that a sign it's time for a new one? It's about 2 years old.
i dont know how old this is but iv fix maybe 6 or 7 fans that are doing that over time the fan inside gets dry and it just slows it down till it wont move anymore if u take the fan off you will find a round peace inside it prob still in the bolt hole if you take that out and add a little motor oil and put it back in like it was it will fix this dont add too much dont want it everywhere and no even if a drop gets on your mother bored somehow it will not hurt it this is not for beginner
