    I would never mean to imply that people shouldn't test, and share their results.

    But others (like me) *have* observed significant (~10C) reductions with the XS-2 fan. So the fact that your new fan didn't help with temperatures doesn't mean that they can't. In the same way that my results don't guarantee 10C-lower for anyone else.

    Admittedly, I changed my HD at the same time, but the replacement supposedly draws more power than the stock drive, so it should actually make things worse, not better.

    A new fan is not a guarantee of lower temps, it seems, but at the same time, it *may* help.

    FWIW, my stock fan is very quiet (and yes, it was spinning), but my unit ran rather warm with it. Some people have reported noisy stock fans, but cooler temps, I think. Perhaps the noisy fans aren't just out of balance, or similar. Maybe they are spinning faster, or are otherwise more effective?

    You're confusing ODT with ambient temperature. The ambient temperature can be 70 C. The ODT temperature can be hotter, and is usually ~20 C hotter than ambient. This varies a lot from part to part. For example, Tjunction for an Intel i5 is around 105C. But I haven't seen an FPGA or CPU that had a Tjunction lower than 85C in 10 years.

    "ODT" I guess could also mean what Intel calls Tcase. I think that's the temperature on top of the chip just underneath the heat sink. Although that is lower than Tjunction, that too is a lot hotter than ambient.

    Without the datasheet, we don't know what the range is or even which temperature the range is using.

    Just another data point (as I had posted elsewhere):

    With the original fan in place in a new Bolt with original 500GB hard drive (April 2017 manf. date), box temps have ranged from 58 to a rare high of 64 (the latter with continuous show transfers taking place), with an average of 58-59 during "quiet" periods (no show transfers occurring) and 62 or 63 during "busy" periods (continuous show transfers); room temperature generally has been around 72-74°F., but getting as warm as 81°F. Small supports (water bottle bottle caps) at each corner raising the box may be lowering the temp by a degree.

    Sound-wise, I can just hear the box (seemingly, the fan) from 9' away in a smallish, totally quiet room (I think I'm fairly sensitive to sound); the sound is no more or a bit less than that from a Roamio (hard to compare, as the Bolt has a higher-pitched sound than the Roamio) and does not have the more mechanical sounds I hear from my Series 2. If the Bolt was in a media center enclosure open in back but with a glass door front, I would not hear it at all.

    Originally, given forum posts, I was thinking that perhaps I should consider a replacement--but then, when I actually compared the Bolt to a Roamio, I'm thinking that I'm doing well.

    I just put the XS-2 fan in my summer house Bolt with a 1TB drive and the ODT dropped from 69 to 59C. Curiously my main home Bolt with 3TB is reporting only 61C with the original fan.

    Interesting info, thanks for sharing.

    Are the two units in similar environments/temperatures? If the 3TB/61C unit is in a cooler room, with more airflow around it, perhaps that could contribute to the lower temperature.

    And I do have to wonder if some stock fans are more effective than others, as some people report lower temps, albeit sometimes along with nosier fans.

    The 3TB unit being 8 deg C cooler -- that's 14F, and yet the room temps were certainly within 5F the same, and the 3TB is taller, blocking more airflow. That's why it was a surprise. It does suggest that there are different original fans. . .

    New Bolt 500GB currently (and seemingly consistently) at 59 degrees, in a 70°F. room, with original fan; placed on a solid surface, but with small lifting supports at each corner, and open around the sides/top.

    When I bought a Bolt (direct from TiVo) in November 2016, they shipped me a unit with the loudest fan I'd ever heard in any A/V or computer equipment. It was manufactured in January 2016 - sitting on a shelf somewhere for 9 or 10 months.

    In March 2017 I exchanged for a refurb unit which was manufactured in January 2017, just a couple of weeks before I made the exchange. (A unit that had evidently been built, purchased and returned really quickly.) This one is nearly silent, certainly inaudible from where I sit unless perhaps I turn off TV sound completely and listen carefully. I really only hear the fan for a few moments while the system is booting. I'm totally satisfied.

    I haven't looked into the operating temperature.

    I bought a bolt+ in Feb. I had to exchange it in April. The replacement was a refurb with a date of Feb 2017. Recently the picture has been horrible, major digital pixelation and no audio. I reset the cable card and it was almost too hot to handle. The entire box seems very hot. I have checked all cable connections, replaced the cables and it ran fine for awhile. The digital noise is back and worse than ever. Could the heat have fried the cable card? What is the fan people have been replacing the stock fan with? What does it do to your warranty?

    I replaced my stock fan with a Noiseblocker XS-2. It was about $10 on Amazon, though currently unavailable there:
    Amazon.com: Noiseblocker BlackSilentFan XS-2: Computers & Accessories

    Currently listed on Newegg:
    Noiseblocker BlackSilentFan XS-2 - Newegg.com

    Opening the Bolt technically voids your warranty, but there isn't a sticker sealing it shut.

    I'd check that your fan is actually spinning, mine was blowing the air down, out of the case.

    Some people have gotten theirs to run cooler by raising the Bolt up a little bit off the shelf, like by putting soda bottle caps under the corners of it. That helps the vents breathe more easily, apparently.

    Or you can put a fan blowing across it, some people have put a laptop cooler pad (with fans) under it.

    You can check the Bolt's internal temperature by going to Settings, then System Information. On the second page of System Information, look for the "ODT" value, which lists a temperature in C. Temperatures up to around 70-72C seem to be considered acceptable. Some run quite a bit cooler. In a 65F room, with the XS-2 fan, my Bolt has been running at more like 55-60C.

    Thanks for the response. I shut down the box and let it sit for an hour or so. Turning it back on the temp was 47. After about an hour the temp was 70. It is up to 73. I will try to put something underneath to raise it up so I get better airflow. I'll keep an eye on it.

    New Bolt 500GB manufactured May 8th. ODT is running 61 with room temperature around 74F. From about 7 feet away with nothing playing, I don't notice the fan. It is noticeable of course when the TiVo first starts and it's running at what is presumably full speed. You can hear it within a couple of feet without any background noise but not loud enough that I would feel like replacing it.

    Where is your bolt located - on a shelf, in an open cabinet, in an enclosed cabinet?

    You could try using Standby to see if that helps.

    WARNING !!!! Whatever you do -- DO NOT ever purchase a BOLT from TIVO or ever deal with TIVO!!! Been a customer since 1999 that's 18 years & we are on our THIRD Bolt -- It's being reported on their forum page & all over the Internet this until is defective. Maybe they shouldn't have had MEXICO build it for them.
    I’ve attached the Consumer Affairs link to the BOLT & you’ll see what I am saying is word for word what is happening to people all over the country.
    But here's the kicker -- I purchased my first Bolt for $299 from Amazon -- same price TIVO charges. Started having weird error messages within 90 days -- same error messages everyone was getting. They said SINCE I purchased it from AMAZON they would replace it but ONLY with a RESURBISHED/USED but this is cute -- they call it "Reused" unit! So that means these units have been sent back to them DEFECTIVE & supposedly they fixed the problem but that is not the case --- The first one USED unit proved to be defective & now I'm on my 3rd & it's also USED. Guess TIVO doesn't give a damn about customers anymore so just wanted everyone to know, clearly the company that

    I USED TO LOVE has gone downhill & right into the GUTTER -- don't make the mistake I did by purchasing TIVO's newest BOLT or doing business with TIVO – period --

    I've had zero problems with the Bolts I purchased directly from TiVo. They work just as well as the ones I had purchased from Best Buy.

    Nothing wrong with refurbished units. I've purchased several TiVo refurbs over the years. I currently have a refurb Roamio basic that has been in use for several years with zero issues. And I have a refurb Roamio OTA that I got last year. Although they did need to send me a new power supply. But that can happen with a new unit too.

    But there is absolutely nothing wrong with refurbs. And it is nothing new for TiVo to send those out as a replacement.

    Well lucky lucky you -- if you check out this forum you'll find you are in the minority -- TIVO's Bolt should be RECALLED b/c it will go down in history as their FORD PINTO !!!
    Since you didn't bother to read what I actually wrote -- they sent me a USED Bolt to make up for the one that was clearly defective & it also proved to be DEFECTIVE. My husband is setting up the THIRD one at this very moment -- we're not hopeful this will be any better than the last two units!

    TiVo's have been manufactured in Mexico for an extremly long time. My S3 OLEDs (over 10 years old) were all made in Mexico.

    My Bolt has been performing fine.

    Roamio OTA refurb has been performing fine.

    I don't know what problem you have (error messages), but if you have an HDMI problem that is TiVo software problem.

    The "Consumer Affairs" site has a total of 72 product complaints or reviews, spanning from present day back to Feb. 2006. Hardly a failure tsunami.
