My macbook is suffering from a non working fan.
- After the firmware upgrade it worked fine, but stopped working. I never really noticed until recently.
- smcFanControl cannot get the fan working (showing always 000rpm and 55 to 80 deg C)
- I have 2gb memory and have no overheat issues...until I run my new EyeTV hybrid which will make it shutdown.

Any suggestions to test the fan and it this is a hardware or software problem

Thanks in advance, Marty

    Either way, I'll run the hardware test and then open it up to see if there is a loose connection or burned out fan...not sure how to test though

    take it to the apple store or send it in if you find out the fans aren't working. they'll fix it if your computer is less than a year old or if you got an applecare plan.

    Have you used the iStat pro widget, its free on the website, it monitors the fan well.

    Unfortunately, its past warranty.

    I'm going to pop off the top and inspect the fan. try to reseat connection. If all else fails, i'll take to guru and get a quote to fix

    I'd expect a dead fan on a Macbook to quickly lead to shutdowns from overheating.

    If I were you, I would get an second opinion and try iStat Pro. On my MacBook it shows my fan speed as I write this at 1800 rpm (it varies a few rpm on either side of 1800.) This utility also reports several temperature reading from 35-50 degrees.

    As someone else wrote here, I would think your computer would either not run or shut down very quickly without the fan. At least that's been my experience on other computers that I've owned.

    I took off the keyboard and checked the fan. Although only slightly dusty, something made it stick. A light push with the screwdriver and the fan was moving.

    I cleaned the fan as best I could(without removing it) and reassembled.

    smbFanControl now shows 1500+ RPM and cooler temps.

    As side note, the only reason I notice the fan was out was because of EyeTV hybrid would tax the processors enough to overheat and shutdown. For most useage, the processor stays about 150 deg F and is OK.
