    If I need to replace another fan I will keep you in mind. I had several old Sony DHG units that needed new fans. They were so hot that the internal wiring became brittle. The OEM mounts went to dust when I changed the fans (80mm) and it was not fun to find replacements.

    As for cooling, just using 1/2" feet can drop the MBT by 1C.

    I'm offering it now on Amazon as a kit, the fan and the silicon mounts. But I've been told not to post a link, so use your imagination. Trying to find a couple Pro,Premiere, Plus, and Bolt users to test and review a couple fans.

    I think it’s okay to put a link in your signature

    Has anyone tried one of the vacuum style laptop fans? It seems like this would pull air across the motherboard, rather than the laptop fans that sit underneath. But, the Tivo being thicker than a laptop and having the sloping sides, I wasn't sure whether any of the vacuum style fans would fit.

    My Roamio was running at 52° when sitting on top my amplifier. It is at 47° when sitting on the tuning adapter. And it is at 43° when "floating" with nothing but air underneath. These are measured during a normal 80ish degree Hawaiian Day.

    The connector you are replacing it with would have to be crimped to the wire,(the connectors are sold with no wire attached) so just cut the bad connector off, strip and crimp the proper one. Crimp tools can be expensive,
    but the result will be much more professional. You could even send the fans out to a place to have the new connectors crimped for you. Check for places that make electronic cables for different companies.

    Moot point since nobody is having issues with the connector.

    Hey FanMan - I'm interested in buying your OTA replacement fan, but I'm a bit nervous about the necessary disassembly. Do you provide step by step instructions? I'm at a skill level roughly equivalent to the guy who posted the YouTube video who got stuck on the step where he couldn't access the two lower screws of the fan. I can open the unit, but I'm not sure how to get under that board and i'd hate to break something and end up paying $300+ for a brand new Roamio. On the other hand, if I can fix this thing for $15 I'd be much happier than sending it back to Tivo and getting a $50 replacement (which will probably just start making the same horrible noises within months). Thanks.

    So, my fan is now making continuous loud noise regardless of the temp, so I am guessing I now have no choice but to replace the inside fan. I've been reading the discussion on replacements and a comment was made about PWM on the replacement fan. Please correct me if I am wrong, but I don't think the Roamio uses true PWM, and thus any of the mentioned fans would work. As I understand it, true PWM usually requires 4 wire leads, one carrying the PWM signal and one carrying the RPM signal. My guess would be that the Roamio just uses the old fashioned (and less efficient) voltage regulation to control speed. It simply sends the fan more or less voltage based on the temp reading of the motherboard.

    I don't have the model of Tivo, but I think there's a video on Youtube that shows you exactly how to take it apart and change the fan

    Excellent - I just found it on WeaKnees and it looks easy. Placing the order tonight - hoping that your replacement is an upgrade!

    Ok FanMan - I've got your kit but I'm not familiar with these rubber grommets. Before I ruin one of these things, can you confirm for me which direction they get pulled through? I arranged the fan with the label towards the motherboard (that's consistent with the original fan). I think I push the grommet in from the motherboard side and pull it towards the hard drive... correct? I'm pretty sure that must be right, but thought I'd ask first! THANKS!!!

    Ooops. The two top grommets pulled through fine. Since the bottom grommet bumps up against the hard drive I had to pull the tail of the grommet at an angle and it quickly snapped. Now I have a fan that is only attached at two points, but I'll keep my fingers crossed that it doesn't start vibrating against the metal. It's back together and working fine right now - quieter than ever!

    Before that fan was supplied with silicon feet, I replaced my fan and just used the top two screws. No vibration or noise problems.

    Can you just pull the hard drive so you aren't pulling at an angle?

    After an attempt to lube my roamio OTA with 3 in 1 oil failed, after 2-3 weeks, I ordered the kit from Amazon. My install experience was similar with twinpop with the bottom grommet. I think I would recommend pulling the hard drive as HerronScott suggests or just use the existing torx screws. The fan is quiet and the MBT is 42C w/ room temp at 74F.

    How old was the Roamio? My fan became loud after 6 weeks. I have two other basic Roamio boxes that are silent after years.

    Yeah, 6 weeks is about right. My original OTA was replaced for the bad fan on Dec 16th. I purchased it on the $199 w/all in deal around Thanksgiving. So my replacement OTA started screaming after 6-8 weeks. I tried the lube which failed in 3 weeks. I could have gotten another replacement I guess. Based on my own experience and what I have read on the net, I believe that Tivo got a batch of bad fans. So, I went with the fan replacement option.
    My first Tivo ever is a Roamio Basic refurb w/lifetime & 3 year warranty which I purchased in Sept. 2015. It is still running with a replacement power brick I ordered after sever spontaneous reboots. I now suspect the reboots may have been due to one of the software/firmware "upgrades" :)
    BTW prior to Tivo I was using Windows Media Center w/cable card tuner.

    Hey FanMan - thanks for the offer, but it's back together and running whisper quiet (and has been for several days), so I'm not worried about it. I'll take a rain check for now!
