Temperature of Bolt

Are you guys are referring to the S4 that's 140 mm or the smaller 120 mm? I bought the larger 140 mm S4 and put it under my bolt. blowing up into the bolt under the cable card compartment, with compartment removed. my bolt sits on this, so the fan is actually functioning as my feet on my TiVo. I only set fan at medium and it's totally quiet and 55 temperature down from 70. Seems cool enough for me

 

I've been using them since the launch in 2015 with great results. And the the Hydra UI made things even better. This is easily the Best TiVo I've owned since 2001. My only real complaint would be the need to use a 2.5 inch drive. I would prefer a larger chasis, like the Roamio Basic, where I could use a 3.5 inch drive in a 5TB or 6TB capacity.

Otherwise with my Bolts, I still have a 4TB drive from October 2015 that is still working great in one. That surprisingly has not crapped out after almost three years of use in Bolts.

Just do an external 8TB drive upgrade (direct connected to the motherboard SATA). It’s painless, AND reduces the internal temps a few degrees.

 

I have my Bolt in a cabinet (Bolt runs @ ~ 60°c) and use the following fan:
SilenX EFX-12-15T Effizio 120x25mm <15dBA <74CFM Thermistor Computer Case Fan

 

I've always avoided having an external drive with my TiVos. I decided back in 2015 to just stick with internal drives with the Bolt.

This weekend I put my Bolts back on a wire shelf. The temps are running around 57 degrees with all tuners buffering. It was at 61 degrees when on a solid shelf, a few inches from the floor. The wire shelf is currently five feet off the ground. I plan to move it to another shelf later this week that is only 18 inches off of the ground. I need to make sure I get everything set before the new TV season starts. I typically don't want to mess with my TiVos again until the Holidays once the new season starts.

 

This worked great! Mine went down from 69 to 51 after installing this!

 

This should not be happening. You have a defective unit. Get it replaced while you can.

8TB external here... 120mm Noctua blowing into a case sans stock fan and OE HDD.
36 ODT; 33.05 HDD.
Would have to get committed to do much better.

 

Now that I lowered the wire shelf my Bolts are on, the temps are now down to 52 degrees. So that was a five degree drop just by lowering the shelf several feet. The wire shelf along with the Black SIlent fan installed works well for lowering the temps.

 

Do you power it with the USB port on the Bolt, or another power source?

 

Thank you for posting this - I find that this specific fan is probably the cheapest and easiest thing that anyone can do to drop the Bolt ODT. I have changed the internal fan on one Bolt, and it made virtually NO difference from the stock fan. My 2 Bolts, just sitting on bottle caps above a hard shelf, have regularly shown ODT temps around 68.

I long ago noticed that the area near the antenna cable, and the metal end of the coax itself seem to be the hottest external part of the box, so I suspected that part would act like a heat sink if it had good air-flow. I purchased this specific fan and set it on the self at the left rear corner of the Bolt, with the air flow angled to sweep the back of the box. Now my ODT is 57 with the fan on low (more than a 10 degree drop), and 54 with it set to medium. I am not even going to bother trying the high setting!

I tried a different muffin fan with less focused air flow on the other Bolt with much less benefit - get this fan if you want to lower your temps without screwing around.

 

I just use a regular 15" laptop cooler off amazon.. 4 fans blowing upwards..

 

I also bought the AC Infinity Multifan S2 and placed it upside-down under (and physically supporting) the back left corner of the TiVo Bolt so that the fan would suck air out of the TiVo vent and blow it away from the device. My ODT went from about 69C to 49C with the fan speed set to LO.

 

I did the exact same thing with the same results as yours. It dropped the temp by -20C. The TiVo fan is on the bottom side of where the hard drive is and sucks air in, and is exhausted out the other side on the bottom vents. I place the AC Infinity fan on the other side to suck the air out of TiVo and vent the exhaust out the back.

 

The back left corner is where the tivo fan is. Is that where you placed the AC Infinity fan ? Does that not cause a problem with the tivo fan trying to draw air in and the Infinity fan trying to draw air out ? Also are you powering the Infinity fan with a tivo usb port ?

 

The Tivo fan blows air out.

 

True be told I can't tell, but I took it that the air sucks in from this post.
Bolt fan and airflow

 

I am surprised at how good this worked for you guys, very cool!

What would happen if the stock fan was removed and that thing was placed under the fan ventilation area on the left making more space to increase airflow since it is surely more powerful than the stock fan? Has anyone tried that to see if its better?

(edited I misread and thought people were putting the fan on the right side)
