A local datacenter reached out to offer us a bunch of APC datacenter cooling towers that they were just going to throw away. Naturally, we said yes, and the first thing we thought to do with them was cool a $10,000 Threadripper.

As a pipefitter that solders and brazes as a part of my job... I've seen worse solder work by people who knew what they were doing. Good job!

Whole room water cooling, a decade later. I remember those videos with Luke's dad teaching linus how to solder copper pipes, and moving from the old house to an office/warehouse building after founding LMG through crowdfunding donations. Brings me way back!

I work for APC's parent company here in the EU and service these units almost every week.
Thinking about how the unit controls the fan speed, you could actually make them react to the water temperature by switching some of the temperature probes.
So that if you have more PCs connected to it without much load, the fans could idle and ramp up as the temperature rises.

TECH TIP for the Sawzall! The rocker plate closest to the base of the blade is to rest against what you're cutting to stabilize the cut. Also contrary to instincts, blade speed is actually your friend so the teeth of the blade actually cut instead of gripping what you're cutting and shaking the ever living life out of you and the object! Cheers!

So nice to see Jake and his husband working together again.
Also, Dennis’ ads are always funny.

Hi, Lock Picking Lawyer Here. Today we are outside the dwelling of a certain individual who dared to execute a lock while mocking me on camera, so we are here to exact revenge for our fallen brother. We have already looped all the ubiquity cameras on the property with a tool me and Bosnian Bill made so we should have free reign to do as we like to these locks…

For a large IT manufacturer I became the expert for water cooled racks, ours had an enclosed rack totally sealed, and a half unit like this on the side, the hold air got sucked in by fans from the back of the rack, through radiators that ran cold water through which then fed back to the front of the servers so it was actually recycling the air, it was actually very efficient because rather than cooling the room or corridor etc you just cooled the rack... I installed some of these in a well known racing team as they had them under their wind tunnel and were worried racks under the wind tunnel would heat up the bottom and give them wrong results... Best feature was magnetic spring loaded doors so in the event of power loss or not enough water etc it would fling open the doors so as not to overheat the servers and give time to fix the issues, the thing is you could manually do this, you can imagine the fun of trying to get the doors to fling open on passing colleagues... I also remember those connectors, they were a beast and at least they used to cost a fortune for the hoses, you could get a rack of fully loaded with blade servers and it would keep them cool... In learning how they work I admit I did pee water all over a customers data centre on a couple of occasions..

Labs should design safety glasses so Linus wears a pair.
Sorry Linus, it might have been really safe, but just one time personally seeing what paint(not metal just paint) chips can do an individual's eyes, now makes me scrunch up anytime I see something similar.

You should hear these when the server room A/C fails and it's 45C ambient.
The max RPM noise is CRAZY.

3:40 Now we need The LPL to break into your office so he can upgrade your security! You could do the real life meme of The LPL picking your bedroom lock 😂

One of my former employers had an APC NetShelter for one of our two datacenter rooms... It was quite nice; we have an entire enclosed hot aisle for exhaust while the outside of the room was rather cool. It had two full-width A/C units with chillers on the roof for heat transfer of the coolant; we had the APC folks in regularly for maintenance, and the internals looked about like that did. Anytime you have water or condensation, you're going to have discoloration, scale, and other oddities on the exterior unless you're doing a daily inspection of your coolers, and that defeats the purpose of the network monitoring and redundancies built into these units. ;-)

7:26 - the foot on the sawzall is the to help stabilize everything. Push it directly against what your cutting. It makes things easier.

Data center equipment like that is serviced very regularly. Because all of their servers and business relies on that equipment being up so they do spend a lot of money in ensuring that everything is service properly and at all manufacturing intervals and they also do that because they have contracts with the manufacturer where if they don't do it the warranties will be voided or it's part of the contracts where they come out at every X hours and service the equipment

This is such an interesting build! It's amazing how you managed to render such temperature results with a previously discarded server cooler. Can only imagine the possibilities of hooking up multiple systems.

Hey Linus! I would leave the bypass open a little. You're going from a large (3/4"?) to a smaller (1/2" I would guess?) hose on the discharge... that's going to build some head pressure, and it might be just fine but it will strain your pump way less if you give it a small outlet by leaving the bypass cracked.
LOVE the cooling and HVAC stuff, very cool!!!

As a contractor, seeing how they used that sawz all made me die a little.
Also really surprised they have a plug in model and they dont have a battery powered one.

These PoS’ are the single worst designed and least reliable things I’ve ever had the misfortune to have to manage. Went through 3 full replacements for a single emplacement in about 6 months before we gave up and retired them.

Always love Dennis' ad spots.

I had 2 of these in a 3 rack setup for redundancy. (Rack, fan, rack,fan, rack) and they are great. Very noisy however to the point where you can hear them through a concrete wall.
Mine had compressors inside the units and the hot coolant would get pumped up to roof heat exchangers.
The water trays inside the units are because they can generate some SERIOUS water condensation. Probably over 1L every 10 minutes or so during rainy weeks, they were like those in door waterfall displays during the rainy season and the water pumps were making a lot of hours.
We also always joked the 2 units could make the racks move at 100% flow.
