So late 2011 i bought a 13 inch macbook pro. Yes i know it's not what geeks do but i like the outside but now to my problem. late 2012 i wanted to upgrade my macbook because i was running out of storage space. I went to a computershop and asked for an upgrade i couldn't do it myself cuz i don't have the tools. I got a 750 gb hard drive and the whole deal costed me 100 dollars. Now since i have this hard drive my computer is getting really hot like 90 degrees celsius when i have chrome and mail open. Now i thought the problem was the hard drive but when i feel where the drive sits it feeld quite cool and the cpu i so hot that i really can't hold my hand on it. Well it's hot. So is it the drive or could it be that the holes where the fan exhaust are blocked? I live in a dusty area and i have to clean out my gaming pc's dustfilters every 2 weeks. Now i must say i have used this pc a lot i played league on it for 5 months 3 hours a day. The laptop is on 7 hours a day so is this macbook just dead and should i look for an upgrade or can i save my beloved mac? Thanks for reading this :D
or could it be that the holes where the fan exhaust are blocked
Sounds like your problem. Macbook Pros are renowned for having overheating issues. Try taking your computer to the Apple Store to see if they can clean the exhaust out for you.
If you're still having issues beyond that, perhaps you need to look and see what is eating up your CPU. If you have some software that is using 100% of your CPU all the time, that could be causing your temperature issues.
(Also, please try proof reading your post before you save it. Uncapitalized "I's" kill my eyes. [/pun])
something common that happens when you install a new drive in a mac is that spotlight will index the entire drive, depending on how much drive you have to index this can take a while and use significant processing power causing your notebook to warm up.
to re index your drive
If you are having problems with your Spotlight index, you might want to start over and re-index your hard drive. In the Terminal, type sudo mdutil -E / and hit return. You may have to enter your password. The existing Spotlight index will be deleted, and Spotlight will start creating a new index in the background. You can re-index other hard drives by changing the command to include their name, like sudo mdutil -E /Volumes/OtherHardDrive.
it is also possible that during the replacement of your drive whoever did it forgot to plug in the fan again, so if you don't hear it going you might want to check on that. quite honestly apple has been horable at applying thermal paste for a very long time they always use too much, you should go get yourself a micro screwdriver set and some artic mx-4 (non conductive right so don't worry :) )
after you reindex you should let the comptuer just stay on overnight just to let it clean itself up, the full article i quoted from above can be found here http://www.macosxtips.co.uk/index_files/terminal-commands-for-improving-spotlight.php
if that fails you should also reset your smc http://support.apple.com/kb/ht3964
if your not sure if you can hear your fan get https://www.macupdate.com/app/mac/23049/smcfancontrol and bump it to the highest setting you'll hear it believe me. that is also a useful tool for adjusting your fan speed if your finding heat is a continuing problem.
