    So i recently replaced one of my Bolt's with a Bolt +.. The Regular Bolt ran around between 59-63 ODT.. The Bolt + runs between 69-73 even on some little legs and the CC cover off.... it is not having any issues and despite the temp the unit is warm but not hot to the touch... Did we ever find out a normal ODT range for these. I was looking at some laptop coolers.. but cant seem to find a normal looking one without any LED's

    I haven't seen TiVo officially posted normal operating ODT ranges. Many folks seem to get temperature variations you get without problems. Others choose innovative cooling methods. There are many laptop coolers available on Amazon and through other sellers which don't have LEDs. Just search this forum or Amazon. My Bolt + is in an audio cabinet. It was getting ODTs as high as 76-79 and its fan was running continuously apparently on high during first week of use.

    I tried a laptop cooler and it lowered temps a few degrees. I now use an AC Infinity MULTIFAN S4 (search Amazon) under my raised Bolt+ and my ODT readings are under 60, usually around 53-55. My Bolt+ fan is off or runs very low. The Infinity is a tried-and-true cooler for AV installations. It's also very quiet. It has three cooling speeds: L-M-H. I run mine on medium and can't hear it unless I'm within a foot of the cabinet. It plugs into any USB port or adapter for power.

    What's your physical configuration? How did you raise the fan and Bolt+?

    Simple and inexpensive. I used two small craft boxes purchased in Walmart which are about 3.5" high, 2"wide, 4"long. I wrapped them in black Gorilla tape so they would not be seen in my A/V cabinet. They slip under Bolt on left and right sides lifting it enough to place fan under it with about 1/2" clearance from bottom of the Bolt. I looked all over for rubber feet high enough to raise the Bolt while keeping it stable but couldn't find them. This works well, is stable, but doesn't look great if Bolt is out in the open. Fan is set to blow air up into the Bolt opening where internal fan is located.

    I've run the Infinity fan 24/7 at medium speed continuously for about a month. Virtually no noise unless I get close to the cabinet. ODT remains between 54-57, a 10-15 degree decrease versus not using the fan. Internal Bolt fan never operates as far as I can tell.

    Thanks! You didn't mention raising the fan. Do the fan's own feet raise it enough to draw air from underneath?
    Also, the Bolt fans blows out, yes? But you're blowing into the fan opening?

    The AC Infinity fans look great. I already have another use for one in mind and I may get one of their cabinet fans for the cabinet the Bolt is in.

    Right. The Infinity Fan has integral feet on all four sides which raise it enough above the surface it's sitting on to be useable. I believe the Bolt fan is an exhaust fan. The combination of raising the Bolt and increasing air flow along its bottom surface regardless of whether the Bolt fan is operational has resulted in a 10 degree or more temp drop.

    For what it's worth... I cut appropriate sized (1-1/2" to 2" diameter) white PVC to 1/2" to 2" length, depending on need, as spacers between stacked components. I wrap the white PVC in black electrical tape or black duct tape so they blend in. Never had a heat issue with good air flow under and around stacked "hot" components. Heat is a killer of electronics over time.

    And the simple DIY method: water bottle (or similar, such as juice or milk container) caps under the box's 4 corners. (And with the translucent/semi-clear caps, almost looking like a "standard" part.)

    Thanks for the AC Infinity MULTIFAN S4 recommendation. I have my Tivo in an enclosed cabinet and it gets pretty warm, so I followed your lead and ordered one of these fans from Amazon. It doesn't move a lot of air, but I think that when it comes to cooling, a little air movement can make a big difference over no air movement. I like the fact that I can power the fan from the Tivo USB port instead of giving up another 120VAC outlet.

    For my setup, I just stuck together a few felt furniture pads and used them to prop up the right side of the Tivo. Then I put the fan next to it so it's got air blowing above and below the Tivo. Maybe the interior isn't much cooler but the exterior feels cooler to the touch so there's probably some improvement inside as well.

    I picked up on of the Infinity fans with 2x120mm fans. The ODT dropped by 20. All I can say is WOW! Great find.

    I use prescription bottle tops. But 4 of anything the same size will work.

    Where and how did you position them?

    I put them under the Bolt. The feet on both sides of the fans allow for a small separation between the Bolt and the fan another separation between the fan and whatever it is sitting on. It works great.

    Thanks for the info! One more question fan blowing in or used as exhaust?

    They are very good fans. I have one on top of my Mini and a wireless bridge in top of that. It's a v2 Mini, mounted out of sight, so the stack isn't visible.

    Sorry to step in but I have my Infinity fan under my Bolt + with fan blowing upward into the Bolt +. This resulted in significant ODT drop. Tried reverse and saw little to no ODT change over 24 hours. Seems that air blowing into and over the bottom of the Bolt + reduces internal temps the most. Makes sense.

    I assume you mean am I using one or two Infinity fan units. Using one Infinity Fan because that is what fits under the Bolt + with the Bolt lifted at left and right corners with various things described above in this thread. Works great.
