Macbook Pro running hot, draining battery after upgrading to SSD?
Sunday, 12 January 2014
Mine did. That was an unpleasant surprise. Googling for a solution brought up untold amounts of speculation and wasted time.
What ended up working for me was resetting the System Management Controller (SMC), as documented here and especially here. You should see that Reddit comment thread, especially if you're also wondering whether you're supposed to enable TRIM.
Resetting the SMC brought down the CPU core temperatures from about 90°C to about 60°C, low enough for the fan to not kick in. My Mac is once again as quiet as it used to be.
