    Again, a dearth of detail. Or do you consider 72 complaints and reviews over a decade, so even fewer during the lifespan of the BOLT models, incontrovertible evidence supporting your case? And out of how many units shipped?

    TiVo's have been made in Mexico since 2000. Our Sony S1 manufactured in April 2000 was made in the USA but by October, they had moved production to Mexico as our Philips S1 manufactured in October 2000 was made in Mexico (as were our 2 S3 OLED's, 1 HD, our Roamio Pro which we've had since October 2015 and now the Bolt that we just bought for my son so you can see we've been a customer for 17 years). Please don't generalize about quality based on the country of manufacture.

    I'm sorry to hear you've had problems with the first Bolt and it's initial replacement but it would be better if you had posted here with what your problems were and tried to get assistance or advice rather than posting what really does seem to be a rant versus a constructive complaint. Unfortunately "same error messages everyone was getting" doesn't really tell people what your problem was.

    Well, I'm not getting any error messages on my bolt, so "same error messages everyone is getting" would imply he's having no problems :)

    You know if you see trolls in every room that you walk in to there's the possibility the other folks in the room might not be the actual trolls..

    Trolls: In Internet slang, a troll is a person who sows discord on the Internet by starting arguments or upsetting people, by posting inflammatory, extraneous, or off-topic messages in an online community with the intent of provoking readers into an emotional response or of otherwise disrupting normal, on-topic discussion, often for the troll's amusement.

    If you are looking for one I suggest trying the mirror.

    Yes I did read it. You said it was replaced with a refurbished unit. Which is the standard policy when replacing a defective TiVo. Again this is nothing new. They are under no obligation to give you a new TiVo. If you were within 30 days you could return it, get a refund and order another one. And even purchasing from Amazon you would be able to return it within 30 days for a full refund. After 30 days you have to go through the TiVo warranty. Which specifically states what they will replace it with. Again, this is nothing new.

    Of course it sucks to get a defective unit. Every electronic device ever made has defective units. And sometimes people get a defective replacement unit. This has happened with every electronic device. It sucks when it happens to you. But it doesn't mean the device is crap. The vast majority of people have no issues. With any electronic device, a small percentage will have issues. This has always been the case. It is nothing new.

    Side note: If you really want to get the ODT high, try transferring some shows from a PC over to a Bolt+. Even with ZALMAN - ZM-NC3 underneath my stock Bolt+ (have never opened the case), I saw ODT go to 70 C.

    It seems w/the above Zalman cooler, my typical ODTs stabilize at around 57 to 62 C.

    The Theraltake Massive 14 cooler I pointed to at Transfer of Lifetime from Series 2 or Series 3 TiVo for $99, with purchase of new Bolt seems more effective even at its lowest speed. The Zalman I bought has no fan speed adjustment. I picked it up as it was on sale for cheap. I have little confidence that either cheap cooler will actually last that long running 24/7 before the bearings go bad.

    You may want to check which model of the BlackSilent Fan you received. It comes in both 3,000 RPM and 4,000 RPM versions. The higher speed fan should give you lower temps than the stock fan.

    There has also been a lot of discussion over what the temperature difference between 60C and 70C really means. The processor at 70C is probably well within it's operating spec. It's common for CPU's to be rated for 100C operation. However, I didn't like the temperature of the case when the ODT was at 70C. It was very warm to the touch. And regardless of spec conditions, electronic devices wear out faster at higher temperatures. A difference of 10C can mean a 2X difference in lifetime. And since the case temperature also goes down with the better fan, everything inside the case benefits - including the hard drive, power components, cable card, etc.

    The stock fan is perfectly adequate, but if you want a quieter longer lasting BOLT, I would recommend replacing the fan - especially if you are already opening the case to replace the hard drive.

    This is partly my concern. I'd be interested in hearing what anyone is finding with a gauge inside the case, as the increased case temperature, long-term, may have an effect on other components.

    Granted my hand isn't very well calibrated, but it felt like the outside top of the case also reduced about 10C with the BlackSilent fan.

    What size is the Blacksilentfan X-2 ?

    The fans I'm looking at are 80mm (3.2"), which just seems too big !

    50mm x 10mm, for the XS-2.

    Thank you.

    That sounds right.

    XS-2 on order for $9.99 shipped thru Newegg.

    It's a Plug-N-Play, right ? No soldering ?

    (I can solder, but will avoid when possible)

    The hard drive needs to be kept below 55 C.

    Capacitors are the next concern. Ceramic ones change value while aluminum electrolytic ones have reliability issues. But that only starts to be a concern with temps. above 60 C.

    The other electrical components should be rated to at least 70 C.

    I think as long as the hard drive and chipset are OK then everything else will be good too.

    I still can't convince my wife to let me test her Tivo. Especially during the French Open.

    Correct, PnP, no soldering. Just match the wire colors of the stock fan, in terms of which color wire goes to which pin.

    The stock fan is 2 wires, the XS-2 is 3 wires, but the 3rd wire goes unused (it would provide RPM feedback to the device, if it was used). So make note of how the stock fan is connected, and connect the XS-2 the same way. If you have a multimeter, you can check which pin is ground, and which is ~12V, as a second way to confirm how the fan should plug in.

    Test it with the case still open, before closing it all back up again. Make sure the fan is spinning, and is blowing the air down, out of the case, the way the stock fan does.

    The Bolt has a little plastic frame that holds the fan down. Take that off the stock fan, and make sure of which way the XS-2 blows the air, before snapping it into the plastic frame. Then mount it to the Bolt.

    None of it is hard, just things to keep in mind. The new fan can probably mount in 2 directions, but you want to make sure the air is blowing in the proper direction, etc.

    I got my PWM-fan splitter cable, and last week was about to open my Bolt, to try running the XS-2 off a constant 12V source, rather than the normal 12V-PWM source.

    But I rebooted my Bolt first, to see how loud the XS-2 is during the first ~30 seconds of startup, and was surprised at how audible it was at full speed. When I had the fan out in the open, before installing it, 12V seemed much quieter. Maybe some of the noise is from the air rushing through the vents, the case amplifying the noise, etc. So I held off for the time being.

    If I really wanted to get fancy, I could use the splitter cable to wire-in a small potentiometer, to let me adjust the speed of the fan. In an ideal world, it would be external, so I could adjust the speed without opening the case (which, to be frank, is a bit of a PITA, and I worry about breaking the clips).

    For now, I've left the XS-2 as-is, and raised the Bolt off the shelf, by putting some plastic caps under the case, for better airflow.

    Wouldn't a Pot just heat up?
    I know, not much, but although it would help reduce the noise, it would simply increase the heat.

    Yes, it would heat up a bit. But the fan draws like 0.07A, as I recall. At 12V, the entire load of the fan is under 1W. So dropping the voltage by a little bit would put a fraction of a watt into the pot, not something that I'd really worry about.

    The advantage would be being able to run the fan faster than the Bolt does normally, on the normal speed-controlled fan plug. But still keeping it quieter than if supplying it the full 12V. I think it would be a net improvement in cooling.

    Other simple-but-effective methods of slowing the fan down could be used as well, if there were suggestions. The bigger "problem" may be that you can't easily keep the adjuster accessible while running. And running the Bolt with a cover not fully installed would change the airflow pattern, and might reduce the air passing over certain areas. The air is currently drawn through the little vents under the case, forcing it through the areas that TiVo intended.
