No my friend isn't ydl, ps3 fan have 2 chips inside, one is for the speed that fan control and the other is for working, the second is off maybe it blow it from the high temp, to understand, when the ps3 is open on the first chip control the fan to go fast to freeze up the temp if the ps3 is hot and then the second control the fan in a normal speed.
Then when the ps3 is hotting the first chip make the fan go faster and the second response, without the second chip ur ps3 fan will not work, sony fix that with 50 euro here in greece AND BE CAREFULL!!! DO NOT OPEN ON YOUR PS3 YOU WILL BURN THE CPU AND THE GPU AND THEN YOU WILL HAVE YDL!!!
I hope that i helps you.
