Much has been said about replacement hard drives (been there, done that). Many have had to replace the remote control. (been there, done that too). Some also have had to replace the power supply (bought it, but not had to do that yet). A few have also had major modem problems (thankfully, not me, yet) Little has been mentioned about the cooling fan though. Mine has been getting noticeably louder over the last few days. For many years now I've had a PC online 24 hours a day in my office to serve various servers and periodically the fan in the power supply gets louder and louder to the point of failing. However, this is the first time I've heard the TiVo fan start to get louder :-/ I have a ready replacement from my second US TiVo which only gets fired up a couple of times a year to record programmes that clash (due to the final death of my last VHS recorder) but I'd like to hear other pepople's thoughts about whether any of you guys have had to replace the fan and if there's a way to extend it's life a bit...?
