Hello, I've had my Macbook for about 1.5 years now and it's been a real bitch lately because the fan doesn't seem to register the heat properly. I discovered the problem when the computer was burning to the touch but I could hear that the fan was on a low RPM. I installed SMC Fan Control and with it I could see that the temp was at 86. It still wouldn't fan so I manually changed the minimum RPM to 5000 to lower the temp. It works but so far I've had to constantly keep an eye on the temperature and the RPM. It's a hassle and if anyone out there has encountered a similar problem then feedback would be the greatest thing. Thank you.
