We still have the $1,000,000 Computer, a cluster of over a petabyte of NVMe storage that can run at speeds in excess of 100GB/s! The problem is, it draws a RIDICULOUS amount of power, and subsequently generates a RIDICULOUS amount of heat… so much that its overwhelming the AC in our server room. Today we fix that… at least we hope.

    Hello, Facilities Manager on a Data Center here. Ideal temperatures, are 21 for intake and no more than 34 on the hot aisle. calculate your warehouse temperatures knowing the desired temperature for your hot aisle. Aim for a hot air temperature and calculate your temperatures from there. Also, Kingspan is way better than any other plywood/GIB/fiberglass solution money wise for temperature isolation, is fast and cheap to build with if you measure twice and cut once, and you can replace walls with it (not structurally, but aesthetically) For sound, they are a little bouncy, but you can always use what Generators use for baffling: sound proof walls (made of fiberglass foam with a frame) parallel to the walls and parallel to the noise source kind of like ------------------------------------- wall sound source ->> ==== buffers ------------------------------------- wall

    LTT is the embodiment of we never have time to do it right the first time but we always have time to re-do it.

    As a professional contractor, NEVER trust what you get from the "professionals" at the store, always check it, I get the wrong fittings every third order.
  • @BrandonRogers91
    As a former datacenter tech Linus is so right about how exhausting it is being behind the server output. The sensory inputs from the sound, air movement, and heat and it’s a dry heat at that. It dries you out and makes you feel terrible quickly.
  • "It's 32 degrees in here, it is HOT" - meanwhile Australians: oh, that's a lovely Spring day!
  • 'it's occured to me we've never actually performed a test of this equipment. What's to worry? Each of us is wearing an unlicensed nuclear accelerator strapped to our back". 😂
  • @DavidBezemer
    One major issue you'll still have is that the two hoses are not well insulated from each other, in a DC setup you'd run the inlet water on the cold isle and outlet on the hot isle side, because now you're reducing the outlet water temperature and increasing the inlet temperature by running the hoses together. For DC modeling that's nearly a 40% efficiency delta.

    Industrial A/C guy here, Referring to Jake in the beginning A closed loop chilled water system does not lose water over time, or evaporate out. That is why it is a closed loop, they add water and chemicals one time and that's it.Unless the system is drained for repair, or leaks water never needs to be added again. Normally you have a closed chilled water loop, and your Chillers will have an open condenser loop, that cools the Machines, and the heat you brought in from the building. This loop does lose water through evaporation in your cooling towers. The condenser side IS hooked up to city water with a check valve, The water is monitored and topped up with chemicals on a regular basis to prevent corrosion, inhibit bacteria etc. Also side note if LMG actually sees this comment, that is indeed a condensate overflow switch Linus was pointing at in the beginning. Those drain pans are pretty rusty, and may be leaking- which could be a reason these coolers were scrapped. If these are ever used for their intended purpose the pans can be easily repaired by pouring in a kit called PanSeal which self levels, coats and seals the pans. Edit, Im watching this video and cringing again. Between Linus' house and this, you guys are helpless when it comes to plumbing / electrical. Get Jake some plumbing classes, or Hire someone with some Trades knowledge to help with things like this, you spent WAAY to much money on fittings silicone etc. This is such a simple project that could have been done in a few hours. (Just constructive criticism not trying to be rude)
  • @zachmiller9175
    Working construction taught me that oscillating cutters are good for literally everything. They're not the best at anything but they work adequately if slowly at basically every cutting task, so if you're not sure what cutting tool to use, always grab the vibrator.
  • As someone who just got a job testing boiler chemistry, you should ABSOLUTLEY get a filter for water entering the reservoir from the main, at the bare minimum. You should also think about regually testing the water, and adding chemicals, to extend the life of the tubes within the systems.
  • @SFSBP
    This really made me understand the concept your mentioned in the last cooler video where you say they pump the hot air elsewhere and cool the whole room and deal with the hot air somewhere more ideal. This is definitely super cool (not a pun) and can’t wait to see what you do with the other 4 room coolers.
  • @Spiffyskillz
    A friendly local plumber/mechanic designer and long time fan here- you are kind of correct by saying that a closed loop hydronic (heating/cooling) system requires a check valve. However, more specifically, it requires a reduced pressure backflow assembly for cross connection control. Furthermore, a hydronic system likely will run at much lower pressure than city water pressure. A pressure reducing valve will need to be installed as well.

    Really dope video, I love seeing Linus & Jake do serverroom upgrading, especially with potentially janky DIY involved, super hyped for pt 2! Reminded me of the early mythbusters energy when they were trying to figure out how to get a project done, love seeing that
  • @lukassawyer2076
    Love the content! Please make sure y'all have some way to monitor humidity and pressure inside that server room. Temperature isn't the only thing to be concerned about. Improper humidity control can cause just as much damage as improper temps. Love everything you guys do keep up the great work!
