    Does one of your fans blow air so that it passes under the BOLT? I bet this would help and has been documented by others as having helped a lot.

    The aftermarket fans seem to help lower the temp for most folks by around 10 degrees C so this probably is helping you.

    It seems there are a lot of variations in temperature on stock BOLT's. Clay did a lot of work documenting this in his thread. His ODT was 73 degrees C on his stock TiVo.

    Documenting my Bolt Experiences...

    So - I upgraded to 4tb.. and while doing it I put in the new fan (blacksilent one mentioned). Temps went down to 56.

    Had some cablecard issues that Optimum (NJ) couldn't bind it. So that took a few days. In those days I had it upside down so I could remove it easily during the calls if needed.

    Checked the temp and it's now 47. Is there a problem leaving this thing upside down other than aesthetics?

    That’s actually a really good idea and I can’t believe I never thought of it.

    You may want to put something under it while upside down to keep the feet level. I know people say it doesn’t matter anymore, but leveling the original feet in the air will keep the hard drive horizontal. I personally would not want my hard drive operating at an angle indefinitely.

    Thinking about it more, some hard drives should not be mounted upside down. Check the specifications on your 4TB drive and make sure it’s ok.

    How's the sound factor from the fan?

    I only hear a slight whiring sound if my ear is within 12 inches. But I have lots of white noise all around the room - need to mask a 120Hz hum coming from a transformer in an electrical closet across the hall of the apt. (They are working on dampening it). Not sure if I woud hear it if room ws silent. ODT is now 54.

    Might as well order on Amazon, return if it bothers you. Blue light is an issue, but can be blocked with tape.

    Thanks. Always humorous/odd to me when fans of this sort include an "accent light"--at least, include a switch to be able to turn it off.

    Yes - I suppose they are trying to make their fan “cool” by adding lights.

    Most LED lights on equipment are too bright, I need to cover with special filtering transparent plastic. This can be blocked with black masking tape.

    Where do you put the tape to block the light?

    I just put some black masking tape on the front part of the fan, and it cannot be seen in the room. There is still a slight blue reflection on the bottom of the Tivo where it curves, but I kind of like it. I was thinking of putting black tape on the front of the white Bolt as well, but I’m getting used to it.

    In any case, my new (refurb) Bolt is going back for replacement - one of the tuners is bad. I thought they were supposed to test this friggin’ things!

    Glad that it worked for you. I went from about 70 to 62 so it sounds consistent with my experience. I'm in a closed enclosure so I may get less benefit from the extra circulation.

    Great solution - thanks again! Yes, mines on a shelf in the open, holding around 55.

    1-year-old Bolt on a solid shelf but space open around it, on water bottle cap supports at the 4 corners, 71F in the room: ODT = 61 right now.

    New Bolt is delivered - all 4 tuners working! Finally. Temp with fan in low 50s. I’m good to go.

    The one currently under my Bolt Plus is a ZALMAN - ZALMAN ZM-NC3. ODT is currently 49 C. This one doesn't have a user-controllable fan speed and is quiet.

    I have a loud one that I bought ages ago. I have another that is non-adjustable but not loud. And, I have one with a dial that lets me turn the fan speed up/down. That one can get be loud at higher speeds.

    Fry's has cheap laptop cooling pads w/fans very often for cheap w/promo code.

    Stock Bolt on a solid wood shelf was running with ODT at 70 C. Just elevating it on a wire rack reduced temp to 68 C. I got one of those $10 laptop coolers (Aicheson) with the blue lights linked earlier in this thread. That only cooled it a bit more to 66-67 C. Pretty disappointing. The fans seem quiet, but not very vigourous.

    What exactly does "ODT" stand for, anyway? A Romaio says "MBT: Internal temperature" instead of "ODT". So, what does MBT mean, exactly?

    I got the same laptop fan with blue lights - holding at 54C. Was 70 w/o fan. On wooden shelf as well. What is room temp? Mine is 72F.
