 You can cool a computer with hot air and heat from a computer in a small confined space equals, well, a whole lot of swath. Fortunately, I have a solution. By encasing my computer in this here grow tent, I wanna be cool as a cucumber. Cool just like a sponsor. Zoho Desk!

To start, I'd like to thank the mining community for the glut of cheap GPUs that they just flooded the market with, and also the idea to encase your computer in a land-row tent. Now, with gaming computers just drawing so many watts these days, it might make sense to do this with a single gaming computer instead of a whole mining rack. Before we get to it though, I wanna just describe why this idea actually isn't all that dumb. There are a number of ways to try and cool down in the summer. You could just point a fan at your face, but that doesn't fix the fact that your room is still super hot. Cracking a window can also work when it's cool outside, but on the days when you need it the most, the air from the outside is probably hotter than the air inside your house. Another option would be to install an air conditioner, but that comes with its own whole set of problems. If you only have a single circuit in your room, there's a good chance that running an air conditioner and a gaming PC at the same time will result in tripping a breaker. Second, cost. Our grow tent costs us only $65, while an okay-ish air conditioner starts at 10 times that. Also, I'm sure your friends on Discord won't be super stoked when you're running a compressor right next to your mic, and it doesn't get to the root problem that we have. You're creating a bunch of heat in a small little room. I have air conditioning that's in my apartment, but that does not help me when I'm sealed in this room just poaching in my own sweat. Which brings us to the final option. Just open the door, maybe? Well, if you live alone, then sure, but yelling at your useless teammate in Rocket League can be rather disturbing for the others in your house, and unfortunately the doors here have to stay closed. So, all right then. Grow tent it is, let's go and build it. All right, let's see what we're working with here. I got this grow tent from Amazon for $65. The reviews for it were fine, but at the same time no one was using it to cool a PC, so... I also saw this one's two feet by two feet, but some reviews of grow tents, not this one specifically, they were like, oh, it says it was two feet by two feet, but it was actually more like one and a half. If that's the case, we're screwed. Oh my god, that's a... that's green right there. I can already tell this is not going to be a girlfriend approved setup, but... There it is. Look at these instructions. Step one, frame. Step two, put the thing on. They're not wrong, but that's not the most helpful. In fairness to Viosun, this seems pretty self-explanatory. I don't think we're going to have any trouble putting this together. One slightly unfortunate thing about doing it this way is that this is a lot bigger than my computer. In one direction, two feet is about perfect to fit a normal desktop. Problem is, my desktop is definitely not two feet wide and it's definitely, definitely not 36 inches tall. This is going to be way bigger than it needs to be, but at the same time, it's the smallest one I could get. Wait, David, what do you think these are for? Horizontal reinforcement? It did not improve the structural rigidity at all. We can worry about those later. Yeah, why is this what's holding it together? Okay, feels not too bad now. I can dig this. I am slightly confused about all the other stuff we have. I wonder if we'd get better performance with or without the intakes covered. We'll find that out later. Oh dear. It's one of those things where they said that it was adjustable, but never mentioned how adjustable it was or like what the sizes were or anything like that. I don't know if our tubing is going to fit in there. Okay, well, this is pretty unfortunate. I asked for insulated tubing specifically because it was black on the outside. We did not get the right one. This is so weird. Okay, is it going to work though? Can we just chuck it in like that? Duct tape it up and call it a day. It'll need some work, but that's going to be just fine. Here's the basic plan. I have terrible awful casement windows. Need to make a big old adapter for it. That's what this is going to be. So we have this right here, hose adapter, also a big acrylic pane. So hopefully I don't block too much light. My favorite thing about this design though, that I had Sarah go ahead and draw me an elephant. This right here, when the hose comes out, it should look like the elephant's trunk. I'm very stoked. Okay, let's do it. Before we try cutting the big elephant, which is going to take about half an hour, I want to just try etching a couple of small ones, get the settings dialed in, and then we can do the full thing and know that it's going to turn out great. I'm super glad we tested out the etching of the elephant first because we had a little bit of a problem. The laser, you know, it travels fast, but when it has to do a tight corner, it slows down and then accelerates back up. Normally what you do in that situation is lower the amount of power that it's putting out. The problem is we're already pretty much as low as our laser will go. It's too powerful for what we're doing today. Instead what I've done is defocused it. So, you know, you have a nice large beam, it disperses way more heat, and hopefully we won't just have an elephant fall out of our piece at the end. As a bonus with these settings, it's only going to take like 10 minutes. To attach our big sheet of acrylic to the window, I'm going to make a bunch of little clamps out of HDPE. The material is a little bit overkill, but it also is the absolute perfect piece of material for the job. And I had a big piece of it laying around. I actually made this right here, the little extractor thingy. What the f*** is it called, David? I don't know. Dust collector! There we go, got it! I love this. We have such high utilization of the shop right now. We're going to be doing this. At the same time, the laser is cutting our stuff out. And if you come over here, our 3D prints have just started. This is going to take us 14 hours. I really wish we had the Pantheon at this point in time, but we don't. So we're running two of them because if one of them fails, we are completely screwed when we arrive here tomorrow. To cut our HDPE, we're using this absolutely beautiful single flute. We can send it through this stuff at like 160 inches per minute. Fricking crazy. Actually, it's going to take half a while because I need to swap out the tools for every single one. I'm trying some new scalloping stuff. Should have just set it up on the Tormach, but whatever. It looks like our elephant's done. I'm excited. Let's see here. Oops. Look at that. We need to take the backing off, but heck yeah. All right. First clamp. Hope this goes well. We need to get a tool changer for this thing. Avid CNC. Make one. I would love it. Everyone would love it. Okay. I didn't need to slow it down a little bit. Got kind of wavy there on the side, but overall parts good. Just need to make seven more of them and I'll see you tomorrow when that's done. Instead of yesterday taking the time to make all of them, I took the time to optimize the G code for it. So no more tool change. Look at that, David. And it was all done with this flat end mill. One of these only takes one minute and 30 seconds now. It's wonderful. We'll have a bunch of them just in case something goes wrong. Anyway, let's go over here. I don't know why I was ever concerned that these might fail. Both of them turned out perfectly. Only problem is that it's blue. It's very blue. So while the router makes us a couple more of those parts, I'm going to paint this black. Unfortunately, Nicholas, who actually knows how to paint things is way too busy today. So I had to do it. Just don't look too closely at a David Pretty plays. A wonderful thing though. This shop jacket. We're finally releasing it. Holy Frig. Come on over here. So as you've probably seen in a bunch of our videos, I have absolutely tortured this poor prototype and it's held up very well. We took a lot of inspiration from Savage apron. If you're doing things like grinding, welding, that sort of crap, this will keep you nice and safe. Go and grab it. You can put a pens here. I was slightly concerned about the acrylic. It's just kind of a brittle material. So if we're getting halfway through the day and it explodes, we're just completely screwed. So I made this one right here out of wood as well. It's going to block light coming through the window. But at the same time, I know it's not going to explode. We do have a little bit of a problem. It got a little bit burned and I'm having trouble cleaning it off. Instead of screwing around, getting all the charcoal off for a while. I think I'm just going to give it a little bit of a burn and then it'll look consistent, hopefully. All right. I think it's about time to pack her up and take it all to my house and we can see if this actually works. What do you want to do first, David, in case the computer or figure out the window? Figure out the window. Figure out the window. Yeah, I was thinking that too. All right, let's do it. I think the easiest way to go about this is to just remove this whole desk. It's going to be a pain. Thank you. Nice. You could also just go kind of over. Now, I did do the math. It should take only about two and a half minutes to heat that room up by five degrees using my computer. IRL, there's so many more factors like how warm your walls are. They're going to suck in a bunch of heat. How much heat's coming in or leaving through your windows? Like where the sun is, is going to make a huge difference depending on if it's coming in through the window. So calculating is a bit difficult. We did run a test, though, in 45 minutes, that room increased in temperature by three degrees, which is a lot when you think about it. The difference between 25 and 28 degrees is the difference between me personally being comfortable and not. Not to mention that typically we'll have a gaming session that lasts for longer than 45 minutes. And you can see what ends up pretty unpleasant after a little while. Ended up getting great. Yes. The best parts, Trey. In hindsight, this is a bit overkill. Eight quarter 20 bolts like these, especially high strength ones, probably good for most deep sea pressure vessels. Definitely going to hold this together, though. I don't know if this is going to work. The curve of the laser was a little bit too much, and it means that some of our holes aren't quite large enough. Now, I did try drilling it out, but it's it's just going to blow it right up like. Also, try the deburring tool. It's not working. I think we need to swap out the wood. We're going to want to protect it a little bit. Just got some simple mineral oil here. It's not perfect for this situation, but it's way better than nothing. OK, this is working. I do think I will swap to the acrylic later because this side plus a grow tent neighbors might not be too happy. Oh, pretty please. Oh, we did it. Ha ha. Where did my hammer go? You got this, bro. It's taking me out of one of five for just a little bit, and suddenly William Osmond vibes all over the place. I have an I fix it kit and multiple sets of hex keys. Guess which size I don't have. All right. This is really solid. I'll put the CAD files down below. So if you guys want to, you know, do something like this with your casement windows, you can to move the air from our grow tent out the window. We are going to be using this rock six inch fan. That's showing off at all, David. OK, perfect. The good news is also it has a low setting. If you don't want to have it be quite that loud. I think we want this fan, David. Maybe just down here on the floor. It seems like a not too bad spot. OK, cool. Fiberglass dust. Don't breathe this. One thing that's very unfortunate about this is that the tent is pretty fricking big. So this monitor, I feel like it's just going to have to go. Funny story, by the way, I got this as an upgrade for my main monitor. It is in every single way a better monitor, except the OSD is so bad that I don't use it. What's the best way to do this? If we go like that, all the cords can come up and over there. And this goes this way. Oh, I really wish they had a smaller one. Yeah, I guess it's going to have to be how it goes. Yeah, there's all the cords. I was excited for like a little bit there when I was like, oh, this is probably actually going to work. What do you think? Out the side or out the top? It goes at the top, right? Yeah, at the top. It's one of those rare times that duct tape is actually getting used for its intended purpose. I watched a bunch of red green last night. Can you tell? Should we dry run it? See how she goes? Yeah. That was kind of underwhelming, if I'm honest. Like it is working really well. Sucking lots of air. This isn't the best zipper in the world. Might have to crack this. Seems to work, though. Way quieter than I expected. There's so much air flow coming in under this door. All right, let's put a PC in there. Plugging in peripherals is not the easiest. I have to remember to turn on the PC before we close her up. There we go. All of our air is going to be intaked right beside where our computer is bringing in air. And then hopefully all of it just gets yeeted out. Oh, this isn't great. It's a bit intrusive. It's maybe up on the desk. That's good. I'm sure the Mrs. will really like that this is her office space now. In fairness, the Mrs. does way more work here than I ever do at mine. So this will probably get way more use now. I think we've done it. Let's turn it on. Barely can hear it. Barely. OK, I can hear it. The temperature of this room has started dropping. It's just pulling in air from the rest of the apartment that is a little bit cooler right now. Moment of truth. Prime 95. Furmark. It's currently 26.6 degrees in here. So if it's what? 30.6 when we come back, we failed. In the last 45 minutes, we have dropped 0.4 degrees in this room. 0.3 right now, actually. So it does look like our CPU got three degrees hotter than original run. But that said, if we just simply played games for another 45 minutes with it before, the ambient air would be hotter, the CPU would be hotter, you know. The speeds are exactly the same. It got a tiny bit hotter in here, but this room is absolute night and day. And what's extra impressive, by this time normally, even without a computer on, this room is getting pretty hot. And now it's so cold. This was a huge win, David. I love it. Grotem, stick your PC in one in the summer. Works great, just like the sponsor. Moonside.
