    Wondering if anybody has modified the case to allow an 3.5" drive to fit (mostly) inside the case.

    There is absolutely no way to fit a 3.5” drive in the BOLT case.

    Kinda makes me want to get a 3d printer and “print” a new top cover to snap in place of the standard side cover that would enclose a 3.5 hdd and a fan.

    A 3.5hdd fits inside the cover by itself so seems possible.

    There already is one. I don't recall the thread, but I've seen the link in here where someone had that idea and already did it. It looked like someone took the small fan cover piece and redesigned it the size of a small shoebox to sit on top. Didn't seem like it would be as effective as this mod would be. There are other options too, such as just buying a small computer case if aesthetics are that important. This thread is great in itself, and I won't continue hijacking it though. You should try making a new thread about what options there are. I just haven't researched it enough yet to go in half … way with a new thread.

    I like this idea, but think it would be better even to just replace the entire top cover. It could even be flat instead of curved.

    I hope this is appropriate to add this in this thread. It not, I will delete and start a new one. I was really hoping for advice, and trying to add on a little.

    I am going to do this to my new bolt+ and have been searching for days to find a fan. My biggest problem is I want it as quiet as possible (less than 15db). I'm also kind of a nut and wanted it all black so it would blend in with everything else that is black, (that would get on my nerves if one thing a different color were to unintentionally draw my eye). I want to hook the fan up so its constant but don't want to hear it when the tv is off. My plan was to try to connect if off the USB port, and I started searching for a 5V fan. I swear I looked at 30 different companies websites to read all the specs. The options are very limited for a 5v fan, its like searching for a larger TB HD in 2.5". The closest I could find for a 5V fan was about 40cfm and 18 or 19db. After several hours of searching, I realized I need to find a way to get a 12V fan to work to get the low decibel I am after.

    I really don't feel comfortable soldering like you did, and found this so I can use the USB port. (max 1 amp)
    DC-DC USB 5V to 12V Fixed Output Step Up Boost Power Supply Module US | eBay

    I have a usb to 3 pin/4 pin adapter, but I think its 5V, and guessing I need to get a 12V cable.

    Of course there is always a plug in 12V connector

    Then my fan either the

    SilenX Corporation - Effizio Quiet Fans

    I will also put a dust filter pre-fan.
    From how I understand the mods that people have done to the case, I think if I get rid of the channels, drill the holes, and even that 33CFM fan for this size case should be plenty with the ventilation to help air flow, but If there's a way to actually figure that out, I don't know what it is. Would this setup work for what I want it to do? Thanks

    Searching for this exact thing .. a NEW modified BOLT cover with room for 3.5inch drive and top fan
    Would be way cool if someone started selling on EBAY .. I'd buy one !

    I purchased an Thermaltake Ring 12 LED 120 MM Fan from Best Buy. It is a 12V fan and I wired it to the 12V lead that goes to the Hard Drive. I cut the wire to the LED on the fan and I cannot hear it at all, and even better My wife cannot hear it either.

    I think it would be even easier, if someone just designed a new case and transferred the motherboard over. That curve is rather limiting, and because of the two pieced design, you would have to go up 2-3 inches. It would just look silly. I would rather have a fresh design that was only a couple inches wider, and could be even thinner if you really wanted to. I wouldn't though. I would get rid of the channels like CIR engineering did. I would create your standard size fan slots: 120mm fan over the main heatsink, and tabs/sides that could pop off if you wanted to add additional fans on the sides and rear most likely 60 or 80mm.
    If you were as high tech as CIR engineering you could probably create a way to make add on connections for those fans, very simple for the rest of us, with easy to do instructions. It would also have to be in black.

    I wish I had a 3D printer to make a new case. It’s a great idea.

    if somebody does make a case, remember the 120mm fan should also blow on the tuner chips. Those get smoking hot and have failed on many people.

    Best,

    I've got a spare BOLT laying around .. would love to swap out the mobo with a NEW airflow case :)
    Square makes more sense .. ditch the curvy design and go black

    Mikeguy, I'm sure you have posted your cooling pad model number somewhere, but I haven't been able to find it. Could you share, please? I just bought a Bolt OTA, and it is running high 60's-low 70's.

    I used to use a generic laptop fan cooling pad that I had around, but then "upgraded" to an AC Infinity AIRCOM S7 model--candidly, I never would have paid that much, but received a substantial $-off coupon from PayPal and so treated myself. https://www.amazon.com/AC-Infinity-...keywords=ac+infinity+s7&qid=1578326247&sr=8-4 The S7 is inaudible in the room (and even when right next to it) when run at its low speed. Other people have listed in threads here other laptop fan cooling pads they have gone with.

    Separately, placed at the side (or under) the Bolt box, blowing air onto it, the AC Infinity Multifans (various models at different sizes, and a few (the S5 and S7 models) with 2 fans wired together); people seem to gravitate to the S3 and S4 models/sizes. All of which are relatively inexpensive--I would have gone with one of these (I was thinking of the S7 dual-fan model, and putting them under the Bolt box like pedestals). A good chart to various of the models can be found in this (and other) AC Infinity listings: https://www.amazon.com/dp/B00MWH4FL4/ref=emc_b_5_t.

    Also, do consider the passive measures of just removing the Bolt box's cablecard compartment cover and using risers (e.g. water bottle caps) at the 4 corners of the Bolt box--for me, these measures alone had a real effect.

    Thank you very much! My Roamio's temp is always around 44°, so the Bolt temps are concerning. I think I will try your passive measures first. If those don't do enough, I might even remove the cover and mount the Bolt on the wall behind the TV in the over-the-fireplace box. Thanks again!

    One thing to keep in mind: the Roamio and Bolt boxes measure temp. differently and so can't be compared--and so don't worry about the difference between your 2 boxes' temps. Before I started with some cooling methods, I think that my Bolt box's ODT was in the mid or high 60s and so, like you, I was thinking of ways to get it down a bit. (I also was subbing in a 3TB hard drive for my 500GB drive, which I assumed would generate extra heat, and I wanted to counter that, if I could easily enough.)

    Thanks for the suggestion and parts for a fan. My Bolt was too loud for my tastes. I first tested just a capacitor across the built-in fan and that was enough to quiet it to the point of not even noticing as my Tivo sits a bit recessed, so the sound was slightly muffled to begin with. A simple capacitor, that's it. Wonder why they don't ship them out like this.
