What are the symptoms that a Bolt is too hit?
Sometimes, show playback performance issues.
In touching the outside of the Bolt it doesn't feel noticeably hot. Maybe its because its a new Bolt. My eyesight is shot, are the only vent holes on the bottom?
Yes. The pics at e r e b o s . n e t » Blog Archive » TiVo Bolt Hard Disk Upgrade and Take Apart and TiVo Bolt Teardown help. I have Bolt+ which is black, so it's harder to see the holes vs. non-holes.
What is your ODT? Without any help of other fans, after a few hours, the top cover above the heat sink should be pretty warm.
Looks like my Bolt was made in November 2018, Model TCD849000VO
I'm talking about the ODT (On Die Temperature) which is the value of some sensor built into the (Broadcom?) chip.

That's pretty hot.
62 C = 143.6 F
I was at 40 C (~104 F) this morning w/my fan setup. I posted some temps in post 50. I don't think I got above 51 C (123.8 F) that day.
Right now, I'm seeing ODT of 45 C (113 F). Room temp is ~74 F.
In the past, when I was using laptop coolers, IIRC the ODT would rise a lot if I transferred content from my Bolt+ to my iOS devices via TiVo's iOS app. I tried one for a few minutes and saw my ODT go to 46 or 47 C. A few minutes after stopping the transfer, the temp went back to 45 C.
(Google makes for a good unit converter. Google for stuff like 48 C in F.)
So I'm thinking one of these https://www.amazon.com/gp/product/B00MWH4FL4/ref=ox_sc_act_title_1?smid=A2AW0W4FKP16S5&psc=1
and raising the Bolt up on a wire rack. Should the fan be vertical blowing across the Bolt? or under it blowing up? or on top of it blowing
up or down?
The bolts do feel warm to the touch especially around the cable card and cable connector. 62 is pretty hot, first thing I'd do is remove the cable card door and leave it off - this should drop the temp a bit (it dropped mine by 8 ). I added a small fan behind my as well and that lowered it a little bit more, but still felt it was running hot, so I purchased an AC infinity AIRCOM S7 fan (a little bit expense, but worth it) and placed the bolt on top of that
The combo of removing the cable card and using this fan has brought my temp down from the high 60's to high 30's / low 40's
ty, following your lead I removed the cable card door and the temp dropped from 62 to 56. Next will be the fan.
I'm doing Temperature of Bolt with my S4 fan and S2 blower.
The pad I put on (previous post) on low takes my bolt down to 42-44. When I turn it off, 55+
Thanks for all the good advice. I have 2 Bolts that were running in the mid to high 60's. I purchased the AC Multifan Mini on Amazon and the temps have dropped to low 50's in about an hour. I have them placed directly under the Bolt fan on the medium setting acting as an exhaust fan. Very impressed.
I put a small fan to the side blowing under the bolt and along the back. Temp 48
Excellent. I forget....did you also remove the CC slot cover? I'm about 7 warmer...same general location but CC slot cover still on. But it seems fine.
Yes I did remove the CC slot, made about 7 difference.
Been watching the temp, staying around 48. Wife gave me 4 one inch thread spools to use as legs so now Bolt has a one inch gap under it. Temp dropped 2 degrees. I don't feel confident drilling holes or cutting case so guess I'm done.
I just set my Bolt on its right side with the fan at the top, it draws in the fresh cooler air from the bottom (Card Cover removed) and since hot air rises its a natural flow helped by the fan. puts me in the upper 50's from the mid 60's
Do you have a photo or link to the shelf?
