    very cool Joe thanks
    It is last years OTA model. I think it was about this tme of the year when I made the switch to TiVo from the now unsupported windoz media center. so I got from the bad fan batch.

    I found the Weakknees youtube video too. it looks super easy to do for someone like me. One thing I do not like about their video is they did not service the device on an ESD safe mat and use ESD wrist strap. while that may not be a big deal to some ESD can kill electronics. With out that equipment I would use caution to touch a metal part of the case before touching the logic board to ground yourself and not work in an area with a carpeted floor, they did not mention any words of caution about ESD.

    so with the cheaper fan van one did you use the silicon rubber things to hold it in or were you able to use the original screws? seems on Amazon the rubber things were some source of complaints.

    I used two of the original screws only. (the top two). But with external fans, that little thing isn't doing much. With my basic Roamio units and 1TB drives, I usually have a 37C MBT in a 72F room. When I bought my fan the silicone mounts were not yet offered.

    I used to have a bunch of old Sony DHG units. They used rubber mounts that broke easily.

    I'd like to see a pic of how you added an external fan.

    On which Roamio? I have three external fans on Roamio units, one on a SB8200 and two on my R8000 router. Oh, one on two different A93 Mini units, but they are 12v wall wart powered.

    Maybe I wasn't clear. I added the fans externally, as in next to or on top of the units. No holes were drilled. After the first one, the rest were my OCD kicking in. :)

    oh interesting, I only have a the Roamio OTA and an A92 mini. I don't think i'd add fans to the router and modem though. the Mini does feel warn at times and has no fan.

    The Mini VOX (A95) is a solid block. The A92 and A93 can support a 120mm fan on top, and my wireless bridge sits on top of the fan.

    The Arris white modems get very warm. I have them where they are not in a living space, so adding a fan doesn't hurt.

    you just sit the fan on top of the A92 or A93, no grill cover or fasteners?

    My modem is an Arris too but an older black DOCIS 3.0 model that I bought before they merged with or bought Motorola and was not really a consumer model, mostly cable operators use it as a leased modem, it runs well. it and my WRT3200acm are in my office room on a shelf.

    All fans have large feet. Most have air filters to protect the blades too. They need cleaning monthly. The new white Arris is when they got warmer.

    Just checked. A93 is 29C, A95 is 51C.

    How did your fan work out? I saw this fan on amazon as well. Do you have any feedback?

    using an anti static mat is nice but really not many techs use them they always end up missing from the bench. The wrist strap well being in IT for 30 years never seen anyone use one of those. If you touch the case its grounded to the outlet that's good enough. I have not fried any motherboards from touching them now overclocking them that's another story. I can tell you that im probably more staticy when driving ask my wife then most.

    My TiVo Roamio OTA 1Tb started making noise off and about 2 1/2 years after I originally purchased it. After reading this and other threads and trying a little oil which didn't work I bought this Weaknees fan through Amazon.......

    https://www.amazon.com/gp/product/B07CYKLRTW/ref=ppx_yo_dt_b_asin_title_o08__o00_s00?ie=UTF8&psc=1

    I could have found a cheaper fan but figured that Weaknees knows a lot more about them than I do and I appreciated their excellent how-to video for fan replacement.

    The new fan mounted easily according to the video instructions, eliminated all of the noise and has been operating flawlessly for 3 months now. Hopefully this one will last longer than the original but if not replacing a fan every couple of years shouldn't be too painful. The day that something not so easily fixable goes wrong will be a sad one.

    One Year Update

    The fan remained quiet until last week, i.e., for one year, Feb. 2018 to Feb. 2019. I've tried unplugging it again, but to no avail. As was recommended I should do a year ago, I'm going to go ahead now and just buy the WeaKnees repair fan and kit. Since I've had both PCs and DVRs go for several years with totally silent fans, I'll definitely be looking at other DVR options in the future when it comes time to replace this DVR.

    New WeaKnees fan came yesterday (2/28/19), installed that evening easily in less than 1/2 hr using the WeaKnees instructional video. Roamio totally quiet now, hope it lasts.

    I know this is an old thread, but surely it's a problem almost everybody will run into at some point.
    I have a trick that works "most" of the time, but not all of the time.
    Here it is: Restart your Tivo (restart menu) Like 3-5 times in quick succession.
    Then wait a little while, and it will eventually quite down.
    Can't hurt...

    After reading this thread in March I opened the TiVo and applied two drops of silicone lubricant into the fan. It has stayed quiet for five months.

    Hi guys,
    I have a roamio ota that I bought in 2016, manufactured in 2015. The fan got noisy and I ordered a replacement per this thread. Then the fan got quiet, so I ignored it. Then, a couple of weeks ago, the whole unit died. So, I guess when the fan got quiet, it actually died. I replaced the fan, but it's still dead. Is there something else I can try or is this unit well and truly dead? If so and I buy another unit, can I keep what's on the original harddrive and use it externally on the new unit? Any suggestions on which tivo I should get?
    TIA

    Have you checked the power supply as it's a common point of failure?

    Sorry, I just noticed that it is not entirely dead. The green power and red when recording lights are working, it's just not sending any signal through the HDMI output.
    So, stop the presses. As I was writing this I thought to check that the HDMI cable was plugged in on both ends. Yes, it was. I 'jiggled' it in my most professional manner, but still no joy. I changed out the cable and, et voila, she is now fully functional. Bad cable, huh. I worked in IT for 30 years and we would only change out a cable (that hadn't been moved lately) as a last resort.
    Thanks for your attention.
