Thought I'd brighten someones day with this. I'm was at work and I'd just replaced a mobo on an old P4 machine. The fan was spinning at full speed and with the side off, was annoying me terribly. So to hush it up I put my finger in it to stop it (which if you do fast enough, tends not to hurt too much...). However later after much blood and a trip to the bios, I learnt that it spins at over 5000rpm. My finger is still bleeding 2 hours later............
LoL. 2 hours though, that sucks. Reminds my of my old cat. He used to get into everything... I was testing a water cooling loop and, so I could have it hooked up/in place, I used a a spare plug from another computer's power supply for the pump and left the one the loop was in turned off... I left the room and after a couple hours I hear the cat scream and look in time to see him run out of the room with eyes squinted and hissing. Not just one long hiss but lots of hisses about 1 second each. Caught him and he had a little cut on his nose... At least he never laid on that computer...
Ouch! I done the same thing when I installed led fans into my original xbox. I still have a little scar.
I got my finger too close to a high speed CPU fan when I first took the side off a computer, probably "checking" what the airflow was lol. It didn't actually cut me but one of the fan blades snapped off! Uber annoying as I had to phaff around buying a new fan
pssht 5000RPM?! the knuckle on my left pinky had an altercation with a 92mm Vantec Tornado which had its grill removed.....
Push on the center hub? I've done this (with finger or pencil eraser, mostly) without any injury to myself countless times. Helpful if you want keep all your
Mine did something stupid, apparently very similar to this as well. I'd just got a new, old case from my flat mate, built a system in there and powered up, just ten minutes later my cat stuffs SOMETHING in the front fan I hadn't noticed. It was a very slow turning 120 mm fan so no harm done. I don't think I've managed to get a wound from fans, I DID manage to touch the terminals of a 230 V fan once, good thing I didn't stuff my fingers in that thing as it was a 47 W steel-bladed one
finger into air intake side: much pain finger into air exhaust side: usually fine. but that's just my experience. centre pushing is probably the safest bet.
We have a Comair Rotron Patriot 230v AC fan at work. It's mounted on an open frame for troubleshooting hardware (ninja cooling.) Nobody’s lost a finger to it yet, but there is a thin smear of bug juice around the inside where they've flown into the blades and been vaporised. Edit, one of these:
