is there a way to test a heatsink?

finished up building my PC and turned it on and discovered that my heat sink fan wasn't on at all. to tell the truth i was kinda expecting it to be turning (slowly), but still turning. it twitched a little every couple seconds but no full rotations.

i was a little worried especially since the box which the heatsink was in was a little roughed up (took pictures of it just in case) so i plugged in the heatsink that i received (much smaller one) and powered everything up and instead of twitching it would do like one rotation every few seconds which would make sense since its a smaller fan etc.

i called up the motherboard company and they confirmed what i thought, that newer motherboards control the cpu fan and its thermally controlled (makes sense) so it isn't really expected to be running once you turn it on.

currently i just installed windows and my cpu meter hasn't been much over 2% this whole time had it up to like 20-30% for a few minutes since my friend wanted to see the picture quality on a movie.

so how do you test a cpu fan? would like to try before i play any games or anything just to be sure i don't ruin my e8400 dual core. i'm sure its fine im just a little paranoid since this is my first build.

any advice/suggestions? thanks in advance

ps got like a bucha fans already directed towards the heatsink so it already probably dissipates quite a bit of heat.

If the HSF is working, the machine will immediately shut down. This is failsafe on all new mobo as far as I know. You can also check the CPU temps, your mobo should have software to do this.

You mean if the HSF is not working, the machine will immediately shut down. :)
