On my laptop, an odd problem has developed. Whenever I press my left shift key, I hear a funny high-pitched sound like something is spinning against it. No other key causes the effect. Is this likelier to be the fan, the hard disk (ulp!) or something else?
EDIT: Oh, sorry I didn't specify! My computer is an Asus U46E-BAL7.
As it happens, the problem somehow went away in the twelve-plus hours I've been away from the machine. I'm guessing ultrasawblade's guess was basically right; some detritus underneath the key could have been partly blocking the fan, causing the fan noise's pitch to change when the key was pressed. It's hard to imagine what else it was unless the CD/DVD drive was invovled.

Please specific the exact make and model. – Dan D. – 2014-02-27T03:29:27.810
Can you give us the laptop model so we can see what's under your left shift key? – miggy – 2014-02-27T03:53:44.450
The likelihood of having your "fan" directly under your keyboard is unlikely. In all honesty every keyboard has its own PCB so what you describe isn't even possible. – Ramhound – 2014-02-27T04:16:58.883
@ramhound not true. I've seen it on 2009 era macbooks - the glue holding the protective yellow tape degrades and corners of it can get pushed into the fan blades by heavy-handed typists (upper left and right in that case, not shift) – quadruplebucky – 2014-02-28T01:27:02.967
