The cooling fan, that is. It had been making a noise for a few months. Today I suddenly noticed a big drop in speed even for basic tasks such as scrolling down browser window. I realised the fan was silent, so I checked with Istat, and the fan was at 0 rpm. I immediately switched off the machine. A very faint smell of burn plastic is perceptible if one sniffs my MacBook. My questions: - The MB was active without a working fan for 5-10 mins at the most. What are the odds that I cooked some crucial part? - If I did cook some crucial part, could a technician tell when s/he opens the MB to change the fan? - How much should I expect to pay (in the UK) for replacing the fan? I'm trying to figure out whether I should get a new MBP 13''. I was hoping to hold back until the next refresh, as the hardware on the current version isn't that different from what I have in my 2007 MB. Thanks in advance for your help.
