I was just using my wife's laptop... The one I recently replaced the screen in after it got run over. The dvd drive was the only thing besides the screen that appeared damaged... I believe it was only run over on that corner, and the fan is on the other side... I'm certain it didn't get run over. Just added info about the laptop, not necessarily relevant.

So, I was thinking it sounded loud like there might be a cd in it... then I remembered there's not dvd drive in there right now... ha. I think the hard drive is a little louder than I recall but I hardly ever use her computer so I could be wrong. It isn't making clicking sounds or anything odd and hasn't shown any symptoms of an issues... I only mention it as it's what prompted me to turn the thing over and look at it. It was a little warm but not overly so.
I noticed, the fan wasn't moving at all. I thought, that can't be good. While looking at it, the fan kicked on, blew out some hot air, the laptop felt cooler, and the fan shut off again.
Googling this issue brings up a LOT of related topics but not necessarily the info I'm looking for.
I am wondering if a fan should be on at ALL times only speeding up as needed... or, is it normal for it to be off when it's not needed? Oddly, I feel like I've asked someone(online or off) about this before but I forget.
Anyway... I just want to make sure something isn't busted. So far everything has been running well lately. I'm just used to my desktop where fans are always moving. :)

Usually when the CPU/GPU reaches a certain temperature, the fan starts to kick in. You should check the temperatures by using HW Monitor(Download links is on the right hand).

Yeah, check your temp, as for the fan, it just depends on your system. I recently wondered the same thing about my laptop. The fan wasn't on all the time, but it does come on and the temp is fine. If your fan is failing, it's not difficult to replace. If you can replace the screen you can replace the fan.
