    I just installed a 40mm x 10mm fan in a Roamio OTA by cutting away the metal plate beneath the fan. It's a tight squeeze, but it does fit.

    Cut away the metal beneath the existing fan. Cut the original fan opening larger with tin snips by making a straight cut down from the outside edge of the existing screw holes. You will fasten the fan using only the two top screws - basically wedging the screws between the vertical plates, so measure and cut to make it work like it does in the photos.. I tried a couple different ways to cut the hole so mine looks messy.

    The fan sticks up about 1 to 1.5mm higher than the old fan. The case isn't all that tight and things go back together fine.

    I had several 40mm fans on hand. This one is 40x40x10.

    For anyone worried about the case halves not sealing because the fan sticks up too much, sealing the case appeared to make no difference in temperature on either side.

    Edit 07/12/2020: I tried two different 40mm fans before selecting a Noctua 40x10mm

    I've been using these AC Inifinity Fans more and more since Christmas, and just noticed the Tivo being "loud" recently. Where did you put these, exactly?

    I've considered "mounting" them more permanently to the lid of the Roamio, pulling air out directly over the HDD and another directly over the heatsink (by cutting holes in the lid and mounting them directly on top). But if you've achieved great success without such efforts, I'd be all ears-- er, eyes-- er, interested in learning more about your approach!

    My tivo sits in an AV rack in a closet; I do have ventilation in the closet, and an increasing amount of fans in the rack itself, but not yet on the Tivo.

    thanks in advance!

    My basic Roamio experience. First, in a 70F room I expect a new basic Roamio to show a MBT of 37C. I have replaced every fan with a 7-blade fan. If you are really worried, I do have a method to cool the MBT down to 32C or lower.

    You need two fans. I use these: https://www.amazon.com/gp/product/B00IJ2J2K0/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 which I tie together with lacing cord and use the USB from the Roamio to power them. They are set to "Low". I place them on the left side since that will be the way the internal fan moves air. I found the 120mm fans not as effective unless you pull the cover and have it blowing on the MB. The HDD generates very little heat.

    [Sorry, I didn't realize you were posting to me]

    lol- that’s ok. Fan performance can vary greatly depending on placement, so I have a few more specific questions..

    Do you by chance have a photo showing your fan setup to close?

    You said left side (while looking at the front of the unit, I’m guessing?), but blowing which way, towards the TiVo, or are you “pulling” air through the unit?

    Are you running your roamio lid-less, then?

    my thought was to cut a hole in the lid to mount the fan in order to maintain protection from things falling into the unit accidentally (I have kids!). But I’m very interested in your setup as an alternative!

    I will try to get a picture of my current fan setup. They blow room air into the TiVo, following the flow of the internal fan. For some reason the board is not letting me upload the picture of the lid "off", which was just raised on one side. Here is a picture without the lid raised:

    If you haven't removed the top yet, this is what it looks like:

    What is your MBT?

    OTA TE4 with the dual fans:

    Note: all my basic Roamio also have 1/2" feet added.

    I still have my original ROamio Basic. It's been running for almost seven years now. I've never had an issue with heat or the fan. But it does sit on a wire shelf.

    Thanks for your photos! They greatly help show what you're doing, and it looks very easy to replicate! You also I think said you put 1/2" riser pads under your unit to encourage better airflow also, is that correct?

    I'm not sure my MBT average right now, every time I go to check it, the Tivo's been in standby mode. We only generally have it on a few hours per weekday, but much longer on weekends. I'll go flip it on and set a reminder to check in an hour or two once it's warmed up. It sits on a shelf in a component rack in a media closet. Only started installing fans in the past several months. I haven't been too particularly concerned about heat until recently. But the fan is finally starting to make noise, so I wanted to at least replace it to quiet it down. I think the HDD might be nearing EOL since it's taking longer to start recorded programs than I recall in the past (although maybe that's just new tivo software?).

    I just turned it on after being off overnight and it's at 39C. I set an alarm to check it again in 2hrs and I'll report back.

    Standby is a different thread, but I never use it. 39C isn't bad if the ambient temperature is around 75F. In the winter I keep my room about 69F. I do put my Mini boxes into Standby, but like I said, different thread. You may find the temp will vary with height too.

    A slow start of programs is not a sign of a HDD going bad.

    2hr update: MBT 43C.

    We generally keep a warmer house, 78F-80F depending on time of day, and the cabinet is basically a hall closet with the shelving removed and a rolling rack installed. I installed an air vent above the door earlier this year with an AC Inifinity vent fan setup to come on around 90F (it's naturally hotter at the top of the 10' tall closet so I have it set a bit higher, otherwise it's always running, unnecessarily). That's helped the overall closet temperatures significantly! I am slowly adding individual fans as I feel are necessary..

    Hmm. I've never had any trouble with standby, but your comment suggests perhaps others have not had a similar experience. After some searching here, I'm coming up short on any threads with standby problems..

    EDIT -- hmm, seems like some folks do have problems with standby. I never have. Mine is a Roamio OTA (not Pro or Premier or whatever). Maybe that matters, maybe not. But I've never had any problems with crashes, missing recordings, or anything else (to my knowledge!).. I have it on "low" (4hr) standby settings. We only watch about 2-3hrs of TV per day (mostly evenings) with weekends in more heavy rotation.

    Both of my Roamios are on High power savings. It's been working fine here. I think there was a time when they had some issues and I had to turn it off. But at some point they fixed the power saving mode and I turned it back on.
