To the people with freezing issues, just do one of two things (or hell you might aswell do both).
1. Make sure your PS3 has plenty of room to breath, I put my PS3 where my PS2 use to be (basically a box) and even though I had no problems with the PS2 the PS3 froze a lot, so I moved it out of the box to a place where it can breath better and it helped A LOT, I never worry about freezing now.
2. Get a shop vac and clean the inside of the PS3 around all the vents, it definitely helped for me.
My PS3 use to freeze all the time, now it never froze in the last 6 months maybe longer.
@NicholasCage, thanks!
