Re: Laptop Fan
The other thing to note is that the CPU fan doesn't always spin on laptops. It will throttle up or down (even off) depending on CPU load. I have an M1530 with a fairly fast 2.5 GHz CPU and even that system keeps the fan off most of the time. It's not a flaw, but the intended design of the fan. If the leads on the motherboard aren't working and the fan NEVER spins up (which you didn't specify) then yes, moving it to USB was a good choice.
