    hi FanMan, et al.

    glad to find this thread. i have a OTA that is 2 years old. it's never been very quiet, and more recently, its gotten very noisy so that i can hear it in the kitchen even though the Roamio is in the family room next door.

    i followed the online video of using Deoxit, and it actually helped, but 3 weeks later, the noise is back to where it was previously.

    FanMan: what are the advantages of the silicon mounts? is it meant to damp vibrations? or is just a way to avoid using the original screws/bolts. i'm not opposed to spending a few extra bucks, but want i want is a quiet fan that lasts. is the kit going to give me and advantage on these two issues over the standard evercool fan?

    thanks!

    checking in a few months later. are you still happy with this fan? beyond needing to splice on the old connector, do the mount holes line up well enough? did you do the "two bolt" connection on top in the unfortunate event that you need to replace the fan again? thanks for any thoughts. trying to decide between this and the Evercool fan. i'm happy doing the quick splice job with the connector if this fan will last longer... (time is money!)

    ok. from my experience, the noise isn't really from vibrations but the fan itself. probably my best bet is to get the basic fan then or the Orion.

    does the Evercool have a MTBF waiting. people reporting that the Evercool fan dying 3-9 months later on some of the reviews is a bit disquieting.

    I replace my fan before the silicon mounts were included. It works great -> Where to get roamio basic or OTA cooling fan replacement
    I bought another since I have two other (older) Roamio boxes. I haven't needed it yet.

    thanks for your thoughts. i'm leaning towards giving the Orion a shot, and if that doesn't work, i may revert to the EverCool. i'm definitely desiring to not have to do this every 3-9 months, so the specified MTBF for the Orion is an attraction to the engineer in me.

    Well.... I understand. My new TiVo OTA lasted under two months. My 2014 and 2015 TiVo boxes are still silent. The new fan is seven blades also. I briefly used another 2013 Roamio which was silent.

    My experience with the new OTA box is not unique.

    yeah... i do think they probably made a poor choice in designing it with this small fan, and they probably had a bad batch. my Roamio was bought Oct 2015 and it has always been noisier than i would have liked. my friends 2014 (?) OTA is still silent after 4 or more years. i'm hoping the Orion pans out...being quieter than the hard drive, as suggested by the other member, really has me cautiously optimistic.

    I ended up getting the Sunon medium speed fan.
    http://www.newark.com/sunon/mc35101v2-0000-a99/axial-fan-maglevr-motor-medium/dp/58T4877
    Other than having to splice the old connector onto the leads, the installation was fairly easy. It was only possible to use 3 mounting screws, as the wires blocked the 4th hole. Now that the new fan is in, the temperatures are about 7-9 degrees cooler than with the old fan. It is much quieter, but definitely not whisper quiet. Without other noises, one can definitely hear it from across the room. I believe I have heard it running at different speeds (loudnesses), but I can't say for certain. I chose the Sunon, because it moved more air (6.5 vs 5.5 CFM), while while still quieter (22 vs 35 dBA) than the Evercool. I figured since it would be operating 24/7 in 80-90 degree ambient temps, the higher airflow would be advisable. Now my motherboard temps are around 38 degrees when sitting on top of the Tuning Adapter, and 33 degrees when "floating". That is only about 15-20 degrees F above ambient which seems pretty good to me. I think the higher speed Sunon fan would have been needlessly noisier, without making a significant difference in temperature. I'm not sure how long the Evercool is supposed to last, but at 70,000 HRs (about 8 years), the Sunon seems more than adequate.

    That's very good. My standard temperature is 37C. One box with a 3TB drive and limited empty space is usually 40C. I may change that fan this summer. All three basic Roamio boxes are below my hearing threshold.

    i ended up with the Orion fan mentioned earlier. just under $14 shipped from Digikey 1st class mail.

    i installed it last night: just like mlun, i found the install pretty painless. (Weaknees video was very clear so i knew what to expect) i spliced and electrical tape sealed on the old connector to the Orion (i am a horrible solderer). the Orion wires were too long and even after cutting then significantly (worrying about my own wire stripping abilities using my finger nails since this wire was too thin for my wire stripper), they were too long and i had to tuck a couple folds into the black retaining clip that holds the hard drive SATA and power cables. not pretty, but it works.

    in short, it's quieter but not silent. its louder than the hard drive, and i can hear it faintly across a silent room, but it's definitely an improvement over the factory one which was always noisier. i too bought it because of the rated 70,000 hr MTBF. i decided to be optimistic and put all four retaining torx screws into the new fan with the hope i won't have to replace it anytime soon.

    as k2ue suggested, even though it is rated at 3.0 CFM, it appears to move more air than the original. proof is in the temp: i'm running at 36 oC so it appears all good. (it was 37 oC for the original)

    @JoeKustra ,

    {New to the forum, not (yet) a TiVo owner/user.}

    o_O

    It was quiet for only two months, or substantially failed after two months?

    I'm trying to decide whether the purchase a Roamio or build my own system using guidelines from Tukka. Low noise and reliability are two important criteria in my case.

    Thanks for your time,

    First, I have two basic Roamio boxes running (2014/2015), one Premiere box running and two TiVo boxes off-line. None make any noise. One was built in 2013.

    I bought the OTA on BF. I ran it for a month. Then I pulled power for a week. When I applied power it was loud. Nothing else was loud. I thought it was running at 100% since my MBT was lower than normal. But eventually I opened the cover and pulled the fan power. It got quiet. I bought a new fan on Amazon and replaced the Chinese fan. This is not the same fan described in early posts, so I figure they changed suppliers and we got screwed. I have been using the Roamio for three months now and it's still silent. I usually only apply power to it on weekends. The hard drive is 60% full. The Fan Van is great.

    I figure it failed after six weeks. But who's counting? :)

    Only you can decide if a TiVo fits your needs. I never push one device over another, since each person has different needs. It's good we have choices.

    Mine started making a ton of noise after only 4 or 5 months. It was so bad that I had to leave the TiVo unplugged most of the time (it's more of a secondary box to our satellite system). Having read all the posts about how most fan replacements are expensive and/or only temporarily solve the issue, I decided to go a different route.

    I mounted a fan on top of the case. A Noctua 80mm ultra-silent fan. It's not the most elegant thing, but it works, and I made it look not too terrible (IMO, at least).

    My 2nd Tivo OTA, a newer one I purchased last fall or later summer I believe, was loud as heck this week.

    I took off the case and confirmed the fan is the culprit. Which was a bit of a relief, as the 3TB drive I put in has a bunch of shows I won't lose now.

    I have ordered the Evercool kit as discussed in this forum earlier, and will give it a go. Looks like it won't arrive til April 26-29 or so, but will report back after that as to how the repllacement goes.

    Following up with report on installing the 'Fan Van' mentioned earlier in this thread.

    Thanks to Weaknees for the video on replacing the fan, which I found after ordering this other fan. I do have another Tivo, which may need a fan replacment. If so, I will order the Weakness fan to compare to this one.

    One comment on the Weaknees video, which I missed. If one has the Roamio OTA, without a cable card, then the first part of the video does not apply. One does not need to remove the bottom cable card slot opening.

    Removing the motherboard to do the fan replacement seems like poor design on Tivo's part. But it is not too difficult. The trickiest part for me was finding the right angle and getting enough clearance to get the antenna socket to pass through the casing to free the motherboard. Mine did eventually, but it was not as easy as shown in the Weaknees video.

    On to the 'Fan Van'. There is really only room for three of the four screw holes to be used, as the wiring is strung through one of the holes. I suppose one could use a clip tie as well in there, but it would be a tight fit.

    It was not obvious to me how to use the silicone attachments which came with the fan in place of the original screws. I tried several ways, but they just stretched. I'm sure there is a trick I was missing. A printed sheet explaining how to do this would help with this fan. However, in the end, the plastic holes were pliant enough that I just used the original screws and they self-threaded the holes in the plastic. That is, I started the screws first, outside of the Tivo, and saw they they self-tapped the plastic, creating the necessary grooves. Once started, I put the fan in the Tivo and finished screwing them in. This is secure, even with just the three screws.

    Once installed and put back together, the fan runs quietly, and the Tivo is functioning normally. The system reports the MBT temperature as 32. My other Roamio OTA, with the original fan reports 35. I'm not sure how accurate this diagnostic is, nor what range is normal here. If other folks know, I would appreciate a note here.

    Overall, this was an inexpensive fix which most folks can do, if they are patient and careful. I will report back to this thread if the fan dies within the next year, or if there are issues with the motherboard temperature.

    I used a 'Fan Van' device before the silicon mounts were included. I only used two screws when remounting the new fan. I feel 7 blades beats 5 blades. My MBT on three different Roamio boxes is usually 37C to 40C and it's very dependent on room temperature. Two boxes have 1TB and one has 3TB (which usually runs close to 40C).

    The Orion fan is still working nicely, and I will be using it on another Roamio OTA I just purchased.
