Aha, so I just wonder if the PS3 fat syscon have different fan speed, but I guess not
You know what its the problem with Sony´s syscon fan on a 60Gb!? They prioritise noise over cooling, on a 45nm Slim Syscon is fine, but get this the 60Gb its running 90nm on both chips, and drawing an abismal 220W in game, while the 2500 Series and above only use 110W or 90W i belive (if i am not mistaken), and both chips use less Amps, the rest i dont need to explain
If you leave the 60Gb on stock Syscon fan, the best it will go its to Level2 Fan, and running the machine to 78/80º on both, only when reaches 90º the fail safe will trigger, untill then the console will appear to be running fine when its actually cooking itself to death.
Colectors say that if you mod a 60Gb they depreciate in value, but i totally dissagree on that, its the only way to preserve the console, even if its 100% clean its still not enough to keep it running long term, thats why the 60Gb die, and become rarer with each day, and more expensive amongs collectors due to PlayStation2 Backwards Compatibility.
Ill just leave this here too see for yourself
Note that its a Debug Test unit DECHA00A (90nm same board revision as the 60Gb)
