Okay hi guys here goes , I have had no problems with fan noise from my PS3 but from day one it has made an annoying little high pitched squeaking noise intermittently . It's really hard to described and totally random , at first i though it was the blu-ray drive as it does sound mechanical as though the PS3 is trying to read a disc or something but it still occurs with no disc in the console. Best way i can describe it is as a High Pitched , mechanical beeping sound which lasts about a second then stops and occurs totally randomly, the ps3 is otherwise working fine and i have no other problems with it , i'm just wondering if this is normal or not as it does get quite annoying . Has anyone else experienced this ? When i first got the console i just though it must be the way the machine works ,as i say it's not causing any problems with the console and it is well ventilated in a totally open cabinet . Any comments / help appreciated , i can't be the only one noticing this surely ?
