I recently upgraded my RAM from 2GB to 4GB. Will this affect the running temperature of my MBP? And how will it affect my battery life? Just curious because it seems to be running hotter now. I don't know if this is true or all in my head. I'm currently using smcFanControl but wasn't able to take down previous temperatures to compare. Thanks!
it shouldn't be anything that would be worrisome, if ever, but I doubt it very much. Major temp rise usually occurs only when one overclocks memory modules (something that's not done with notebooks) but aluminum heat spreaders or better cooling usually negates it.
