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

[Skybuck Flying]

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.

You're an idiot.

At full bore utilization in 104° C environment, they do NOT need a fan.

That is how they are designed.

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

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.

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.

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

You wrong about that:

cisco epc 3928 apperently has a fan in it.

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

Bye,
Skybuck.

Do the technicolor tc210 cable modems contain a fan ?

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.

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

Maybe the ment the TC 2100, fiber optic modem ?

Hmmmmmm.

Bye,
Skybuck.

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:


Want to join my fan club?

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.

The naive never stop sticking their heads out of the sand!
