So after having an issue with my palmrest (you can check my previous posts) and getting a system replacement, I am beginning to notice some weird behavior from the processor fan. It seems to sit at 0 RPM and spin up to ~3.5k RPM seemingly at random. It basically has no correlation with CPU load at the time. It just spins up the fan whenever it wants to. When it does, it spins up for about 23-30 seconds. This obviously creates a distraction in a quiet room. Whats also weird is that sometimes when it starts to spin up, the system will abruptly power down the fan. So instead of spinning up to the speed described earlier in this post (and spinning for 23-30 seconds), the machine just quickly turns it off abruptly (like after 1-2 seconds). Any ideas?
I have run several rounds of the pre-boot diagnostics and everything returns green. Can a Dell representative comment on what the minimum fan speed is for this laptop (besides 0 RPM = off).
