    Wow! That's a *huge* difference! As mentioned, I'd like to reclaim the space above it, but I might just try pulling the cover to see how it responds. Also concerned about added dust, pet hair and what-have-you getting inside which can contribute to heat and other problems. Does that seem to be an issue?

    Apologies... I was unclear. I meant the possibility that the I/O bezel plate (the oval section encompassing the ports) remained as a unit that could be attache to a decorative front plate. ...but that is neither here nor there ... not important to functioning ... to which you addressed marvelously IMO ... DOUBLE THUMBS UP!

    Personally I've found dust to be a particular problem with free standing devices ... the problem being the potential for an ongoing high volume of air with its potential to convey dust, dander etc. Now with enclosures ... the potential exists for the creation of a smaller ... more controllable environment ... but YMMV here ... depends on how much and method of air circulation. Now in a fairly air tight enclosure ... your dust potential is reasonably low to begin with ... but heat retention ... the problem. I had such an enclosure .... nice looking ... but no air. I resorted to using 4 - 120 mm case fans placed vertically. The bottom fan had a form cover attachment so that it had decent filtration for dust ... the top was left open as a vent. (I 'ballparked that air flow would be cut in half at least with the foam) ... and as a meter ... I placed 2 thermometers top - bottom in the case so at a glance I could see global temps for the enclosure. Hahaha ... at the time I thought high tech BABY! ... but that's bears skins and obsidian by today's standards.

    What about putting the main board in a case designed for mineral oil cooling?

    ... was intrigued by the notion (heard it before years ago, but scoffed it away) As it turns it, the theory and controlled practice seems to be fine, with some thermal advantages ... but in a real world setting, the set up to do it well would be relatively expensive, somewhat fiddly, elaborate and potentially messy. Granted, it would be a neat conversation piece ... but as far as cooling, IMO, the advantages would have to be weighed against the disadvantages* for actual 'real world' in house installation.

    Just have to say....Im OTA now with an excellent Dig Antenna, pointed right at the dig transponding tower @ Mt Soledad in San Diego! Got rid of the cable card, signed up for Hulu Live TV (44.00 Mo.) and then we just have Tier 2 of Cox's Internet and a digital phone pkg connected to the service (ISP) just for discount purpose! From 229.00 a month...Down to 100.06 a month in addition to Hulu's live TV set up, everything is working perfect! And the cooling of the Bolt is Fine Now!!! Cable card really heated up! And were saving about 800.00, actually a bit more annually! A couple of two people even with a second tier plan, and were not gamers...our data usage out of 1024GB per month.... we only use about 7-8% of that a month! Ching!!!! Save, and Much Cooler!

    PS...Also have added SSD's to both PC's, and they both start up ready to go lightning fast, in 30 seconds or less...so much less time on the internet!

    Nice! We've thought about "cutting the cord" for years now but currently we're living too far away from any broadcast towers for OTA. Interesting that the cable card generates enough heat to be noticed though.

    I have a brand new Bolt OTA and I am wondering how you guys are reading ODT. I have looked at the number at TE4:TiVo->MENU->HELP->Account & System Info->System Information->ODT a few times over the four days I have had the unit and it has ALWAYS read 59. I will assume the units are degrees Celsius. Maybe it's that stable, but I don't think so. During that time I have raised the unit up from sitting on the component below it to up on three-quarter-inch blocks. Additionally, the temperature in this room changes about 3 to 5 degrees Celsius (maybe more) throughout the course of each day, so the TiVo's temperature should not be more stable than that.

    Do I need to do a reboot of my Bolt OTA in TE4 each time I want to see this number updated? Otherwise, where can I watch ODT change in real time? TIA.

    I just check my ODT there--it's different at different times. (Right now: 48 in a 69° F. room, with the TiVo box sitting on a fan cooling pad set on low.)

    Sure enough! I look at it this morning and it reads 57. Finally a different number! Thanks!

    I'm curious - folks who have improved their cooling via ideas from this thread, have your boxes stayed up or succumbed to the four flashing lights of fun? I had the cable card door off mine, but my Bolt died today (and it was a replacement for one that died 14 months ago). Thanks!

    I have been experimenting with TiVo Bolt cooling a little. Has anyone else tried standing the Bolt vertically on it's short straight side, with the angled side in the air? That puts the (small) exhaust fan at the top, and since heat rises, it seems to help. I have seen an 8-10 degree ODT drop by doing this. Mine was running 63-64 flat, even with some 1/4" spacers at each corner. But, when I turned it vertical with the fan up top the ODT dropped to 53-55. You will need to ensure the case has a little space to draw air at the vent holes, but that's pretty easy.
    No other mods at the moment, but I do have a XM-2 Blacksilentfan and an idea or two to try.

    I just use the Blacksilent fan in my two Bolts and then the Bolts are located on a wire shelf.
    That has worked well for the last few years.

    after my first Bolt died, I went with cooling. Bolt still died a year later. I moved to an external 3.5” drive.

    As suggested (somewhere), I removed the cover over the cable card, and put them on wire racks that lift them up a half-inch or so for better airflow.

    I had a Bolt+ sitting on top of a cooler with a couple of fans blowing at it, and temperature was around 50, noticeably down from before using fans. Still died before it was 2 years old. I had several TiVos, some fairly old, and this is the first one that died. TIVO shipped me a replacement, which I have decided not to cool. Perhaps the cooler blew to much dust into it?
