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!

Also you can flip the blade. So if you cut something that bends you can pull it towards and have the springyness work for you. Oh... And use finer tooth blades for metals. Oh...

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..

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.

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. ;-)

[@MikeHarris1984]

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

Those fittings you cut off are called union couplings. Normally you would install those for quick and easy servicing of pumps or assembling of pipes. My assumption is they had a pump on those fittings and simply removed them before tossing out those machines.

[@killax7]

If anyone is wondering, even if they found the same brand and size union, small manufacturing differences can make them not fit. Before I take a union apart on a heating job I mark them all so I don't mix top/bottom on the unions.

[@cesarpalmos8235]

@@killax7 I was a tradesman plumber for 7 years and have never had a problem using a new half with an old half of a union coupling. The whole purpose of a union coupling is quick and easy access to components at a frequent service interval. They seal with a rubber gasket. If it leaks, simply install a new gasket. Compression fittings are fittings that seal using tight tolerances. They mate metal on metal and are usually one time use only. Often the male and female side will distort to make a perfect seal, thus every compression fitting is slightly different and not compatible with other fittings. Compression fittings are the fittings you may be thinking of.

[@userid5826]

plumber here, just my thought too!

[@Toesmasher]

The bypass is so you can manually adjust pressure through the system. so that if your pump solution moved more water that the radiator can handle, you can bypass some water and avoid blowing up fittings. (I’m a pool guy, we do this to waterfall and jet pumps to adjust how the water flows down the falls for example)

[@MikeHarris1984]

Data centers use water to air chillers. Because running air conditioning with the compressors and everything is extremely inefficient and very expensive at that level. So data centers usually have cold water non-potable piping running up and down the bays where if they ever need to install a chiller somewhere on the raised floor they can tap into a valve and install a new chiller and then the chillers usually face downward meaning it pumps the cold air into the floor and then in front of the servers there's four tiles with holes in it for the cold air to come out The hot air rises into the ceiling where the chillers suck from the top and usually the walls there's a handful of chillers around the walls of each bay. But that's why these don't have internal pumps or anything because those pipes that are run through data centers are already being pumped and under pressure

[@chadhowell1328]

The amount of air that comes out of raised floors is also insane. I was shocked the first time I raised a data center floor tile and got blasted in the face with massive amounts of cold air. Lifting that tile was also another story because I wasn’t aware of how heavy they were lol

The In-row coolers draw the hot air (as high as 75 degrees F) across 72 inch radiators that circulates 43 degree F coolant from our outside cooling towers.

I mean, this is why Central heating/cooling has return vents along with the supply registers. It's supposed to recirc the air when the Fan is running, to greatly reduce temp differances between rooms and floors. Biggest problem is a lot of Thermostats only have auto/on settings for the Fan, so usually only circulate air when the AC or Furnace is running. Ideally, you'd want to set the fan to run every so often to even out the house, but need to find a Thermostat that supports this.

U guys should do all urine liquid cooling and see how good it works. It's amazing!

[@bobingabout]

Yay, Dennis! More Dennis please.

3:39 This is, indeed, a LockPickingLawyer approved method for getting into a lock.

[@plagueless9829]

As a plumber your solder job looked pretty decent for someone who has never done that I was thinking oh shit here we go because I’ve seen some of your older videos with plumbing but I’m impressed there

18:16 "Mystery Powder" got me hard

[@beepbleepboop]

i love the sound of the fans in the background, they sound like an ambient synth pad

[@Zeus180]

4 seconds ago is crazy

[@EricBentleyW]

I think I know exactly which datacenter this was taken out of. Standing in front of these on your lunch break on a hot summer day was so refreshing

[@FreakyDudeEx]

after the sponsor ads, i now really believe that denis is now really the face of the fun loving guy of the company in the videos on youtube... even though he does actual work as well...

[@D4M14N1989]

I’ve specced and built server rooms using these coolers. The amount of airflow they can push is completely insane.

[@lucasrem]

We used this cooling in my Server Room too, it makes sense, only removing the hot air. You need a seperate room for it to work.

[@mrman991]

I used to work at a place that had these between each rack, they were plumbed straight into the mains water and we'd frequently get alarms that there wasn't enough water flow and complaints that other companies in the building were having trouble with their water supply.

[@rwjehs8101]

Lol that sawzall work was tough. That big metal piece at the base of the blade is for you to put against whatever you're cutting so it doesn't jerk back and forth.

[@AlexanderVRadev]

OMG I can't remember the last time I actually watched a sponsor add, but Dennis at the end is the best part of the video! I guess they learned how to make sponsor adds from Jay. XD

[@orangef1uxx]

Man as a refrigeration tech i love these videos of Linus getting his hands on large commercial cooling equipment.

[@Neeboopsh]

the foot in a reciprocating saw is there to steady the work. the teeth are only one way, and cut while the blade is moving toward the foot. the foot will anchor the work and make cutting very efficient, if its otherwise moving around from the blade's interaction

[@TuthHurts911411]

Tub of water likely uping temps as it can absorb room temp. Need to balanced the reservoir AKA your blue tub with the radiators to get a proper circulation rate of water.

6:53 "It's not called a Saws Most" 8:30 the solder flows where the heat goes.

[@kevincox]

When using a saws-all if you put the guard up against the thing that you are cutting it will move a ton less. This is because it cuts when the blade pulls in so when cutting it will be stabilized against the saw body which you are holding (hopefully stablishly)

[@alepouna]

Those fans on 9:30 sound so musical its so nice

[@dishmeup]

I did brazing (howeever you spell the soldering metal to metal how they did) in highschool a few times and you did better than i did on my first time so wouldnt worry to much about it being kinda half assed

[@ThatRandomDude914]

That ad was perfection
