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.

Lockpicking Lawyer was about 0.2 seconds away from lockpicking your studio before that apology.
🔓
Most likely through the backdoor 👌
Lol
“This is the lock picking lawyer, and as you can see here LTT’s $100m studio uses $50 Schilage home locks with no security pins. Binding on one…..”
We have a click on 3. Oh he apologized? Never mind then.
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!
Hearing him call it brazing hurts though
@@Doubie. it did, and then I saw the propane torch and thought "Not with that you're not."
well, you've seen worse caps that people who knew what they were doing, I doubt he got full penetration on that solder, I'd be very surprised to see that joint cut or even a picture of the inside the adapter. ( yes I know you dont need full pen for it to not leak, but cmon, full pen or bust. )
@sorcierx2604 Edit: it did leak so he didn't have full-pen.
considering the system was originally designed to run coolant and not water, I'd still like to see full-pen... and actual brazing to be honest. I doubt that system had an inhibitor run through it too.
What i like about ltt. Is that they promote doing things yourself as long you have the tool or desires for it. They could easily have a pro do it. But its fun seeing that anyone with effort patience and discipline can do pretty much all.
And to me that i was raised with "never pay for something you can do yourself unless paying for it leads to more earnings" and "always try before paying and do your research so you dont get scammed" these videos are a treat.
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…
That's when they change every lock in the LTT building for much more robust, harder to crack locks.
Got a click on 3
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.
That unit could probably cool that PC more than fine even with the fans off totally!
@@electroshed Oh for sure! But in the video they were talking about connecting more PCs to the loop.
@@kili7658 I mean surely if you set it up right, you could just cool a LAN party, and thats a half unit, I mean if anyones doing something like that, its Linus..
APC Guys it's the leader in and even on the front fan there's APC SCHNEIDER ELECTRICS CAN EMPLOYS ME OR LINUS CAN PAY ME TO COME TO CANADA AND MAINTAIN THIS SUPERBE ENGINEERING FROM MGE AND SCHNEIDER...JOKE SO
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!
wasn't that very dangerous what they were doing holding the pipe with their hand? I thought linus was going to lose a hand
@@kerolokerokerolo *lose a hand
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... And use shorter blades whenever possible.
Also... They are dealing with COPPER... You can cut that with a manual hand saw without a problem. I'm a fabricator and now an engineer... I hate it when people don't understand the power of basic tools... or dangers of power tools.
@@ianhoyt2638 thank you for the correction! edited :)
@@4Gehe2 thanks for the advise, as an absolute ignorat of the topic, it looked kinda dangerous and I'd have been good if the explained the proper way of doing it
So nice to see Jake and his husband working together again.
Also, Dennis’ ads are always funny.

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!
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.
I had a friend who got a little bit of steel swarf in his eye. This was in a country town so his Dad drove him to the nearest hospital (~1 hour drive) to get it surgically removed. In that time it had started to rust and they had to cut up his eye a bit too, went from a few days recovery to wearing an eyepatch and having to put all sorts of medicines in his eye and down his throat for almost a month.
Up
Judging by how nice the screwdriver came out, (i got one and it's pretty great) those glasses would survive warzones if they started making some.
You should hear these when the server room A/C fails and it's 45C ambient.
The max RPM noise is CRAZY.
But they are great for when that happens... or they thermal throttle and everything shuts down.
honestly I'm surprised they weren't wearing ear protection
Instant perma-tinnitus
The New Delta fans...
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 😂😂
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.
AI comment, bot account
7:26 - the foot on the sawzall is the to help stabilize everything. Push it directly against what your cutting. It makes things easier.
Also I wouldn't even cut it with this tool, I would cut it with an angle grinder. Makes the cut much easier.
@@DG_427 I'd just use a pipe cutter. I would not have to worry about any metal shavings entering the system.
This is what happens when "smart people" don't understand basic tools. 😂
@@cdsmock4512 Define "Basic".
@@Adroit1911 I'd say more people have a sawzall available than a pipe cutter.
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.
Skill issue
Theyre working for us nicely
@@BichaelStevensyou got lucky then, from what I can tell. Even their techs hated the sight of them, lol.
I'm not surprised. A $6,000 price tag for what should be an extraordinarily simple device tells me they are over-engineered. Unless you mean the entire system to include the cooling device outside.
You'd think that a water-air heat exchanger is not THAT hard to build, especially for a company like APC.
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. ;-)
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.
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
sounds like a McDonalds ice cream machine lmao
Thanks for stating the obvious.
@@intellex551 I, for one, learned something new.
when the cost of going down far exceeds the cost of PMIs (preventative maintenance inspections, military term), you service that stuff all the time.
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.
I'm genuinely curious as a relatively enthusastic DIYer: I have both a corded and a cordless recip saw from a relatively cheap big box brand. I find myself mostly using the cordless from a convienence factor, but when I have a bunch of stuff to cut, especially if it is metal, I find the effort of running an extension cord to be worth it as I find the corded rips compared to the cordless. Sounds like a hard disagree from you though?
Seeing that solder job hurts my HVACR tech heart
I always go corded when I can. Battery is just one more thing to have to replace on it whereas my corded ones are literal generations old and still going strong.
@@ParanoidMarvinMk2 I have both battery and corded skill and circular saws if I’m honest the corded one is the tool of choice on site, the battery one is awesome but only used in emergencies.
I also have both versions of the reciprocating saw but I tend to work with hard woods(oak mostly) as I do restorations on old barns and buildings in the Uk.
@@johnriff85 if I’m honest every time they need to do a trade job it hurts lol.
Considering ive done HVAC, splash, sparks, chippy etc etc I cringe the moment they pick up a tool.
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!!!
We use these on ships in the entertainment spaces, super useful for mixed racks of gear in enclosed spaces.
Really hope none of them ever leak coolant in a big way.
FYI, zip ties work great to temp hold pipes for cutting.
why zip ties when we have LTT cable ties?
My bad ; )@@El_Makong
@@El_Makong Why use cable ties why you can spend 75 dollars on some 4 dollar ltt branded magnets 😆
@@ancientweeb5984 i dont think the arch are wide enough for those pipes
This is going to end up cooling linus' pool
You mean heat? You don't really cool pools lol.
@@NWinnVR Ice/coldpools. They keep them at 4-8C or so. though this wouldn't really work for cooling the pool now would it.
I think y’all missed the joke 😂
Yep, just another write-off
We used something like these but running off essentially a much larger version of them sitting outside. Most of the year, the entire datacenter was cooled by just a few fans and pumps.
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.
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.
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.
@@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.
plumber here, just my thought too!
7:20 casually throwing metal shards everywhere with powered machinery.. Yup that's linus!
Old tech that we used in our DC's where we had issues with CFM. These things eat power. We moved all our DC's to pull in ambient air and evac hot air out of the building. It was cheaper to cool ambient air then try to cool recycled hot air. This required sealed racks and control of hot and cool zones. But this same design can be added to small areas (Home wiring closets and small shop DC's)
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)
3:44 Linus making sure August 2023 doesn't repeats 👀
What happened then?
@@ianw1387I’m guessing he’s referring to Steve getting butthurt and making a defamatory hit piece video.
@@samlevi4744it really wasn’t a hit piece, it was more like fair criticism imo
@@elongatedmusketgun9185 Although Linus was definitely in the wrong in a lot of cases (if not all), Steve definitely blew it out of proportion for views. We got better videos because of it, and the employees probably have better working conditions now, but it's hard to not see it as a hit piece.
@@elongatedmusketgun9185 Then why did Steve go out of his way to avoid getting LTT's side of the story despite doing that for situations like the faulty GPU racks that SET HOUSES ON FIRE
jesus the sawzall cutting scene had me gritting my teeth
It made me really appreciate my one-handed cordless saw.
@@brucecouch9191 what happened to the other hand ? /s /jk
i mean, they did say "im a noob" but it was still painful haha
I definitely could not have stood there and watched, someone needed to educate Linus more.
It's a useful too, but it's very dangerous.
My dad works at a company that makes these at the scale to go on top of buildings, and when I got to tour the production facility, it was super cool! You should look into somethijg similar near you, I suspect Alex would love it!
Always love Dennis' ad spots.
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
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
I don't see sub floors as much these days, usually pods that are hot aisle containment like these APC units in most DC's I have been to recently. Though I have to say they suck when you have to spend hours in the hot aisle patching servers etc.
CRAC units
We have few of those collecting dust in the warehouse of the company I work for... basically the whole company relies on reselling things like that, aquired from closing data centers for next to nothing or sometimes free... some of it is new in boxes and they are replacing it with exactly same stuff 0_o
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.
Dennis' skits for the sponsor spots are always great
This is my favorite type of video at this point. Absolutely LOVE the sever/extreme enthusiast content
i am so hype for the office water cooling, linus's stare after unveiling all the ones he got you know he doing it
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
0:44 best ltt ad ever?
Lockpicking lawyer is gonna make a video titled "picking Linus's house lock"
There's got to be some way of combining these with Linus' swimming pool cooling solution. Worst case, free wave machine!
Linus may actually do that. Put one in his server room at the house and use the pool's cooling loop. That may actually work well.
@@Darkk6969He basicly has the same solution already in place.
As an HVAC service guy who was the North Eastern APC in-row cooling tech this made me weep a little... The connectors you cut off were flare connector unions.... Npt. IF they were factory fittings. And once you got into the setup of the system you can force all of the valves open their spring returns on power failure.
interesting, i used to work for a server cabinet maker here in the uk , 2014 to mid 2015, and they were developing something similar while i was there, i helped to assemble the test/prototypes, doing the electrical parts...
As an hvac tech, the rust on the side of the coil is a sign of leaks in those bends. Hope you like replacing coils.
Hmm why is that? I'm not doubting you. I would think the rust would be related to condensation on the coils over the years
@@itech301 That would be way way worse if that was the case.
As an HVAC tech, you're wrong. Tube sheets will rust from condensation. The tubes and fins are unaffected. This is normal. Tubesheets are only partially structural and aren't so important after assembly.
@@SuperS05 For the kind of money this thing cost I would expect those coolers to have been manufactured with copper or stainless steel tube sheets, though.
@@ChristopherHallett economies of scale. APC probably bought all of that off the shelf and assembled it. Stainless tubesheets double the cost of the coil.
All LTT sponsor ads should be with Liao.
100% agree
Liao Tech Tips
we do custom air conditioning units for big buildings and labratorys also for server rooms firls thing low humidity ,2nd thing full insulation 3rd proper heat went === good cooling
Bro doing those kinds of things is literally my dream, I used this type of machinery when I worked for renault in the engine development department, and I always wondered what would happen if you used this kind of cooling power on a computer. Thanks for the entertainment
The segways are getting crazier! That is a full commercial produced by LTT
Segues. Look the word up.
Oh no the man who runs a business and buys an inconceivable amount of tech has to run 15s ads 😱
You raise a good point - they SHOULD get sponsored by Segway. They could race them around the carpark.
@@ChristopherHallett Sadly they're out of business. Or at least they discontinued the product people actually know them for; I dunno what they're pivoting to, probably crypto shit or AI like all the other tech companies.
I mean where I live the regular tap water comes pretty close to those 7°C even during summer, wouldn't wanna use that probably cause of impurities building up over the years, but it's probably a workable solution with some filtering.
As someone who builds data centers, those units are intended to cool a data center where one "hall" can consume 5-15+ MEGAWATTS of power, with 48U racks packed to the gills...
you should worry about the metal shavings falling down the supply and return. they could clog up/cause damage to the radiator internally. Also, its copper, a soft metal, please use a copper cutter instead!
I watch for Dennis's sponsor breaks. Makes me laugh every time. Good Job.
I will never skip a Dennis ad
I've been waiting for a gem of a video like this
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.
nice!
gotta love an ac unit that big, want wait to stand infront of it on a hot summers day
We had the full rack in row units at my old work place, one hell of a beast
And they have another 4 to leverage, quite how, should be fun.
I wasn't even aware of these products, ever though have worked around APC ups's that are more than 'room sized'.
I have been away from Linus for about two years and I am back baby, I am back.
Linus is the goat
I used to fit these, we called em APC hotisles. Ours worked reverse, it would pull the air into the middle then out through the floor, removing it from the datacenter and reusing the heated air to warm the offices. We cooled it with regular tap water!
......best part of video...... Dennis with his mystery powder lol!!
13:45 *flashbacks to whole room watercooling*
I LOVE these kinds of videos! These are by far my favorite xD
It's overkill and equally cool in my eyes hahah
I never thought you'd show anything like this. I cool my house with a 3.5 ton Drake scroll chiller that circulates 50/50 ethylene glycol and water at 5 degrees C through six fan coil units totaling a 4.5 ton load. As a result I have a six zone A/C system. The load exceeds the chiller capacity because the chillers don't run all the time.
I don't liquid cool my computer, but if I ever did, it would be very cool (pun intended) to use some chilled water. I doubt the chiller would notice.
This is kind of my dream. There is a serious Irony in my home. I live in an ironic state where my old home doesn't cost much to heat per se, because my office is so toasty from my wife and I having gaming PCs here as our daily drivers. So in the middle of the winter, I am dressed for the beach, until I want to grab a glass of water, when freeze my ass going to the kitchen. If I turned the heat up for the rest of the house, then the office would be so hot that I would be sweating with the window open. It has occurred to me that the dream would really be to have two heat loops. A summer loop with an outside radiator, and a winter loop that can dump into the A/C system to distribute heat through the whole house.
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.
@@Demoralized88 Ideally one wouldn't assume that something so simple as leaving the fan on hasn't already been tried and wasn't nearly enough.
Please keep Dennis on ad duty lmaooo
I love him
That was the shortest and most Non-obnoxious ad / segway I've seen since... Idk.. but a Long time, thats for sure! haha
Good job Dennis and keep doing what you're doing! =)
nice to see linus doing stuff i understand (plumbing) because I've been watching it for the last 8 years and understanding 10%😅😅
“This is not your normal water cooling system” Yeah no shit, it’s 8 feet tall and is meant for a server room.
Dennis does the best ads😂
I would LOVE to have one of those.
I have a lot of waste heat from my heating system in my heating room and with this I could use it to pump it back into the house
The server room at my work has a AC unit that works off refrigerant that is cooled by a condenser unit on the roof and a second AC unit that runs off the building's Chilled Water. Not sure what else the chilled water would be used for besides cooling the building in general but it seems to be great for server rooms. That unit has never had an issue but the unit with the condenser goes down at least once a month. I'd love for my work to adopt these types of units and just go full chilled water but I'm guessing someone likes having the "redundancy" on paper and their might be capacity issues with chilled water as that unit did struggle to keep the room cooled back when a quarter of the servers were render nodes running 6 GTX 1080 Ti each.
In an nerdy voice "That's not brazing, that's just soldering" lol
That's exactly what I was thinking too. My dad's a plumber and that is all we ever called it.
The nerdy cook inside of me wanted to know where the Creme Brule was.
I don't always watch ad plugs...
But when I do, it's because Dennis is presenting!
The chiller units to serve these units are even more impressive.
I love the way this sponsor spot was done. Infomercials are hilarious
As a viewer I actually prefer the content where Linus doesn't put himself directly in harms way(like fingers right in the path of a saw). I much prefer when content creators promote safe working conditions. A lot of people feel pressured to skimp on safety at work for various reasons and people end up maimed or dead because of it.

This was the FIRST AD by ltt that actually made me want to buy the product advertised, those few short seconds with Dennis were so funny I now actually am considering getting a roborock so that I don't suffer the same fate as the man in the ad...lol
Dennis Is finally back BABY!
Not gonna lie, Id be more inclined to watch these sponsor ads as long as they have Dennis in them..
I’ve specced and built server rooms using these coolers. The amount of airflow they can push is completely insane.
Nice sponsor bit at the end .. actuall something I enjoy watching (already got an older one)
3:39 This is, indeed, a LockPickingLawyer approved method for getting into a lock.
4 seconds ago is crazy
Something that's helped me a lot with these valves is that they're ALWAYS configured to be closed when perpendicular to the pipe and open when parallel
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
I so love Dennis' commercials!! So funny, even makes this, um, boring video funny 🤣
Denis you have outdone yourself
Man as a refrigeration tech i love these videos of Linus getting his hands on large commercial cooling equipment.
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)
Jesus thats a big cooler
My damn fridge cant even cool that much
Glad you got this box for only $12,500!!!
Mr linustech i love you brother 😊
See, this is the stuff that constantly inspires me to build my own server!
Classic LTT “hey, here’s a totally weird niche thing. Let’s use it in a completely different way it’s designed.” I absolutely love these types of videos!
18:16 "Mystery Powder" got me hard
Linus, you’re not allowed to call employees your friends. We’ve been over this before.
I love how these videos went from Linus and co building the jankiest imaginable cooling solutions with whatever junk from the auto parts store they could get their hands on, to Linus getting his hands on discarded purpose-built enterprise/industrial equipment, and still doing some of the jankiest things possible with it
I run a small datacenter. It has 24 server racks and 12 of these In-row coolers. They have been running since 2016 without a single minute of downtime. The side of the servers that exhaust hot air, is called the hot row. 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. The foam around the pipes is to prevent condensation and there is pump for the tray to remove any moisture from Datacenter. the fans are rated for 10,000 RPM sustained. These do not cool the fluid, they cool the air.
"Saw saw" is a brand. It's the best known brand to a point it's associated with said tool, like Q-tip and Band aid is so associated with its products. The actual name of the tool is, "reciprocating saw"
Now, if you only had gotten the brand right... It's "Sawzall".
There is no brand sawzall

@@jgush1337 Sawzall is a trademark and brand name. The actual name of the tool is a reciprocating saw. It's one of those terms that were coined and became popular and synonym with the tool itself. Like saying "google it" and so on.
