Definately for this, The old fat models had more than a few heat issues, its either that or wait for it to die and pay sony to repair it, I think sonys repair service is like $150 for the PS3 no matter the problem. Also some of the older games had issues that caused the system to lock up, (Madden 2007 im talking about you) and some PS2 games that arent compatbile with the software BC of the 80GB models. If cleaning the system dont fix it I would look for a new hard drive, pretty much any Sata 2.5 Laptop hard drives will fit, but its best to stick to 5400 rpm models if your worried about heat in the system
