Film the inside of your cable modems ! (Reveal if fans are inside or not)

Hello,

Some of todays or future cable modems seem to contain a processor with a heatsink and a fan on top of it.

Apperently gigabit ethernet speeds/wireless speeds might require either a processor with a fan on it, or multiple processors without fans.

I certainly do not want another device in my house with another fan in it.

I would like to own a cable modem in the future which is fanless, to prevent dust/heat related issues.

Therefore I ask all NERDS to open up their new cable modems and fill them on the inside and post videos of it on youtube !

So we can get a glimpse of what is TRUELY inside the new breed of cable modems.

Very important topic.

If cable modems start to fail in the future because of overheat, it's basically game over in a big way.

Don't let it happen, start filming !

Some questions:

Do the netgear 6300b cable modems contain a fan ?

Do the technicolor tc210 cable modems contain a fan ?

Bye, Skybuck.

Hello,

And ofcourse please post youtube videos of the internals of your cable modems on the internet:

Especially these two models:

Netgear 6300b

Technicolor tc210

Me interested to know if they contain pesky fans or not ;)

Bye, Skybuck.

I have a ZOOM cable modem that was over heating because I had it on top of my router. It gave me problems that even the Comcast service tech missed replacing my cable box instead. When I found it to be getting hot I placed it on some Styrofoam spacers and cooled it with a fan. The modem is sealed but just the fan blowing onto the outside case is all you need. Fans are your friends. I have one blowing onto my Vizio 42 inch HDTV I use as a monitor. It doubles as a space heater for those cool nights and early mornings.

You're an idiot.

That is how they are designed.

Stop guessing as you go, and then posting your retarded spew here. Go get a goddamned education.

My new Comcast box is "Touchstone Arris." It's silent and just a little warm. Has vents on the top and bottom.

Make and model of one such cable modem that has an internal fan. I deal with whatever Comcast is renting this week, and none of them have fans. Even the typical modern cable set top box does not have a fan. However, what does have a fan are the various DVR (digital video recorder) boxes, which generally do NOT include a cable modem. In general, if it has a hard disk inside, it will have a fan.

Nor does anyone else want a fan, which is why cable modems do not have fans inside.

I will happily sell you an unobtainable future cable modem. Just pay me now, and I'll ship it to you when the future arrives.

Video? A still image will not suffice or don't you believe that fans can rotate?

Welcome to Google images. Start here: Type in the maker and model number of your cable modem and skim through the photos which usually will show the PCB and insides.

$75 at Costco for a Motorola/Arris SB6141. You'll probably blow up whatever you install, so check the warranty before buying.

No. That's because the Netgear D6300b is a wireless router without a cable modem sold only in Germany. The US version is the R6300: Try again on the model number.

No. That's because Technicolor modem product numbers are in the form TCxxxx where xxxx is a 4 digit number. Try again on the model number.

One can only hope.

I had a Netgear 63XX ADSL modem (guessing it's highly similar with minor changes for ADSL vs Cable), no fans. Worked fine, got killed by an electrical storm though.

The set of chips for cable modem and ADSL would be different.

One reason, is ADSL modems are now highly integrated. A complete modem/router with four Ethernet ports can be contained in one Broadcom chip. That's how my ADSL2+ modem/router is built.

The cable modem will also have increasing levels of integration. At one time, there would be a tuner and some sort of decoder on the front end, then a general purpose embedded CPU for routing, plus something for a four port switch on the back end. And some of those chips could be squeezed together, leaving tuner and SOC (system on a chip) as a possible solution. It really depends on sales volume, as to whether the money is in the business for continuous improvement.

Take as an example, the STB for digital television. Everyone and his dog made gear at first. Once the initial surge was over, and TV sets came with built-in digital TV tuners, there was no market. Suddenly, you couldn't buy a decent STB, many chip companies stopped making the necessary chips, and there were only a handful of models left. That would be an example of where the market left the developers behind. There'd be no way to pay for innovation. I now have to pray that my digital TV STB never packs it in, or I'll have to buy a new TV set. My STB connects to the computer, and I watch TV on the computer screen. Any firmware bugs in that garbage, are there forever, with no one caring to fix them. Yet another generation of orphan electronics.

You wrong about that:

cisco epc 3928 apperently has a fan in it.

I saw one on youtube ?! which is pretty scary ! ;)

Yeah lol my ISP isn't too good with numbers, thanks for correcting that ?

Maybe the ment the TC 2100, fiber optic modem ?

Hmmmmmm.

This video? The fan is hung onto the heat sink by the video author. Notice the twisted wire "mounting".

The Cisco EPC3928 does not have a fan. Photo of the guts. No fan:

I didn't correct it. Please make a super-human heroic effort on my behalf to get the numbers right. If you have problems, search for your version of the model number and see if anything appears that looks like your mystery modem.

Nope.

Ummm....

Do try harder to go bye bye.

That's a pretty highly integrated design.

Tuner in the bottom left corner. Feeds SOC under the heatsink. Two Wifi modules on plug-in connectors. And a Broadcom GbE switch without a heatsink on it.

A flash chip up top, for the SOC processor. A DRAM of some sort, on the right hand side.

What more could you want ?

Just because you saw it on youtube, especially private videos from youtube, does not make it so.

Do you own or rent? I decided long ago to buy. So many choices.
