I just checked, my new Premiere has a noisy fan. The harddrive is quite as can be. If I open the Tivo up and unplug the fan the noise goes away. It is a rattling or ticking sound.. Somewhat like a bad bearing. I'm getting kinda' disappointed here. I have an issue with HDMI through my receiver not working and now I have a bad fan. I can put up with temporary glitchy software. I went through that 10 years ago with my Series 1 (still working) and they got the software issues sorted out within a month or so. But a fan going bad within a week? I don't want to send it back and loose all the programs and go through the hassle of new season passes and ANOTHER cable company 'truck-roll' charge, plus being without this Tivo on my main tv. I had an old series 1 or 2 fan from swapping out the stock fan for a higher cfm when I added a second hard drive, plug fits but it does not spin up. I'm guessing that the variable speed fan on the TivoP must spin up at a lower voltage than the older models?? Any chance that I could get through to some kind of higher level tech support and have them just send me a replacement fan? It's all of 5 screws and a plug to do it. I've had Tivos forever and replaced so many drives and fans for friends and family I can't even count.. Too bad they are all older SD boxes or I would already have spare fans around. Any others with this problem?
