I recently replaced my hard drive with the 1TB hybrid drive from iFixit. I also upgraded the RAM from 4GB to 8GB. I’m a novice at this so I thought things went pretty well. Now my mac seems to instantly heat up and start running hot when I open photos. Any ideas or help would be appreciated. Thanks! On another note, it also seemed to be running extremely slow a couple of times when photos wasn’t open but I had a couple of webpages open. Could that have been particular pages?
Sounds like you have a bad SATA cable. Follow this IFIXIT guide: MacBook Pro 15" Unibody Mid 2010 Hard Drive/IR Sensor Cable Replacement and you want to use this cable: MacBook Pro 15" Unibody (Mid 2012) Hard Drive Cable I would also check the systems firmware.

Actually it does not sound like something is wrong. If you have recently imported a huge number of photos, the app will need to index them and it can run hot for a while. Just let it run until it finishes.
Have you verified with Apple with regards to the Quality Program? Make a trip down to the Genius Bar and verify whether your unit is still eligible for the FOC replacement.
I have the same problem, and my MBP’s case has never been opened before. I think it is just that photos app is really process intensive sometimes.
