    What gauge wire do they say the T-tap is for, and what gauge wire do they say the spade connector is for?

    Well that particular one is 14 - 16 guage, but they have several different sizes listed on there you can get. I have to make my way out to the garage tomorrow and find my guage measurement tool and figure out what size to get. I just havent made it out that way yet. Too many shows to catch up on :D

    The power supply wires are probably 16 or 18, and the fan wires are probably about 22.

    If you have a drive fan with bare wire leads (or clip off any connectors--leave a little wire to splice to something else in the future), you might be able to remove the plastic on the spade connectors, slide them down the fan wires to thermal safety, strip enough insulation from the fan wires to give you enough bare wire to fold over a time or three, insert that in the barrel of the spade connector, and flow some solder in there, although if the wire takes up enough space, crimp first, then flow solder, and after it cools slide the plastic back down to cover the spade connectors.

    I was actually thinking about putting one of these on there. I have a lot of them from over the years when I have bought fans. I could clip off that one molex end (in red), then attach the bare wires and it'll have 2 different hook ups, and then at some point if I decide to change things around I can just unplug whats there and then plug in the new fan. This way you can put different stuff on there if needed. You got some GREAT ideas! :up:

    I didn't realize your junk box was that well stocked.

    I started to also suggest as an alternate to putting the spade terminals on the fan leads that you could attach a 4 pin Molex to the power supply leads (might as well find the +5 lead as well and do all 4 wires) and leave the fan's lead stock.

    This has the advantage that a set of T-tap and spade connector will be the right gauge size for both the power supply wires and the leads from the thing in your picture.

    Be sure not to have that 2 wire thing in the photo floating around inside the TiVo with those bare pins energized and exposed.

    Scotch locks and other such splices are never a good idea. Best to do what it takes to make a proper crimped splice termination.

    My TiVo is behind glass doors so fan noise is not a problem for me.
    But when building PCs. I use zip ties (not looped) to secure the fan to the chassis, and small chassis grommets in compression to act as insulators/washers between the fan & the chassis.

    Why not?

    You do understand we're talking about adding a hard drive fan (that probably comes with a 4 pin Molex connector or passthrough) to a TiVo that only has a SATA power lead?

    There's more than one way to use a zip tie?

    Even "properly sized" they can cut individual strands of wire which is not good.

    If I had to splice wire and only had scotch lock or wire nut as options. I'd use a wire nut, over any kind of self stripping connector.

    But that's just me... your mileage will vary.

    We aren't talking about splicing wires, we're talking about tapping into them.

    And what I'd do on DC circuits 50V and under at no more than a couple or four amps is not necessarily what I'd do on 120 or 240V AC circuits.

    Back to the TiVo case fan, my JMC arrived yesterday and I just put it in. This thing is straight out of the Milford Academy--I'd never know it was there. Sys Info says it's running at 35°C (Normal). I've had it plugged in for about 15 minutes. The fan is currently pointed towards me and is about 3 feet from my ear and I can't hear it.

    For future reference, the seller is mitek-products. Though it was delayed several days by USPS, the seller shipped quick and did everything else you can expect for in a seller. Plus it's less than half what WeaKnees wants for the same thing.

    If you're going to pay $24 for a fan you might as well buy an actual Tivo replacement fan and get 3 of them while you're at it for that price.

    Stumbled upon this thread looking for a part number for the fans in my Tivo HD and Premiere XL.

    After seeing the comment regarding oiling the fan, I did just that. After peeling off the label, there was actually a little rubber plug there. I put in a drop of 3 in 1 oil, replaced the plug and label and reinstalled.

    I've only done the Premiere XL so far, but now the fan is dead silent!

    Thanks for the suggestion.

    edit: Just did the JMC OEM fan in the Tivo HD and it is now silent as well.

    I'm not sure how long just the oil will be good for, which is why I recommend the light grease for body and the light oil to keep it slippery.
