Water Cooling a Network Switch!

[AlexTheGreatish]

One of our 10 gig network switches is kinda loud, so the obvious solution is to water cool it.

inb4 i see a intel stock cooled red camera

So are you going to water cool the whole network rack and then hang the radiator out through a window....?

[DrMacintosh]

Wow, a 25min video from LTT?

@AlexTheGreatish, Because you used only copper, you could have used silver sticks (copper with 15% silver alloy) to solder the heat pipes properly and have the best results (regarding the heat transfer).

Other than that, good job!

 

If you ever need help or recommendations regarding this kind of stuff (heat transfer problems) don't hesitate to PM me.

I am pretty sure most people put Noctua 40mm/20mm fans in netgear and dell switches and call it a day.

 

Interesting to see the amount of ASIC chips though in only a 12 port unit. 

 

Also Linus, on the black being positive, networking gear runs typically negative in enterprise. Most gear accepts -48v/24v and everything is wired as such. I dont know why but its the first thing to look out for when running power.

I love how unnecessary this is, but it makes sense as practice for the RED camera.

 

Out of curiosity, why not get a simple manual mill? Busybee tools sells basic ones in the lower mainland, and full-on shop mills come up on Craigslist and auction regularly. Manual mills aren't outrageously expensive, although a CNC is preferable. Even a simple manual mill with a DRO will provide some options.

I think that internal RJ45 port is RS232.

Would have been easier and better performing to simply have a single piece of copper covering all the chips rather than making individual squares and joining them with one heatpipe, but not a bad job at all.

Sooo cringe-worthy!! lol

In one hand I envy you guys having all those tools and toys to play with and little to no care at all. On the other hand the OCD in me is always sooo annoyed by how you do everything half-assed lol

And I always got amazed when something still works after all the carnage

Anyhow kudos! Loved the video - apart from the fart bit lol

Let the record show that they misspelled "-cisco" in a video about networking gear.

[dalekphalm]

Not bad, considering.

 

Though I find it highly amusing that they turned a 1U switch into a 4U (5U, possibly?) switch

I can't believe I've never noticed that until now.

[PeterBocan]

@AlexTheGreatish I have an idea: what about a big chunk of passive copper heatsink cooled by low-profile Noctua fans? That should fit into 1U wouldn't it?

So, how many DB's is it actually now, after water cooling it successfully?

Hey guys, I haven't been receiving notifications for the past 2 LTT videos. Can someone please help me? I have all notification turned on for LTT

One of the few things I remember front CNT/CNA class.

Are the videos in your subscriptions?

They're in my subscription feed, but not in my notifications inbox.

I didn't even think of that... but yeah... they never did test the "after" noise. I'm certain it's quieter, but that pump will still make noise.

I like the Red White and Blue tubing choice.

Moral of the story:

 

 

Enjoy!

[MisguidedChoices]

Excessive amounts of employee time, effort, and resources.

 

All to prove that it can be done. This is why I live for these videos.

Love seeing the Maker side of LTT mix with Linus' insanity! Great video, and appreciate all the additions to the CNC router. LTT should do a tour of their shop area so that people can complain about how it isn't up to industry standard /s. But being honest, it would be cool to have a tour and get a behind the scenes look at the MFG side of LTT.

Side note: If LMG gets a mill, I will be sorely disappointed if it isn't CNC. It would go against everything I have learned about Linus and his over-the-top-ness(see RED cameras, which coincidentally cost about as much as some CNC Mills). Alex's wish list is now a metal lathe, welder, and mill, for those keeping track(LINUS!). Slight tangent, but I wonder if LMG will eventually need to hire someone that only works on manufacturing all of LMG's hair brained schemes.

Side-Side note: I appreciate that LTT is keeping their child-like attitude with what they do. That's one of the reasons that I watch this channel, because videos like this show that they still have that child like wonder in everything* they do. They seem like big kids with big toys, and as long as they are being safe(which they seem to be if you see the response to my last rant), I will always watch and support these projects.
