I've had my 60Gb PS3 for 18 months now. Approx. 6 months ago it started to overheat so i took it apart, put some new thermo paste (artic silver) on the heatsink which seemed to fix the problem.
4 months later it started to make the same noise so i took it apart again which, again seemed to work. Last week it started to play up, yet again, so i bought a new 19 bladed fan for it and put it in.
Now it just seems to permanently make this noise, which makes me think it's a problem with the software tripping the fan into action even when it's not hot. Could it be a problem with the software? Can anyone help please?
