DIY cardboard PC chiller (Road to sub-ambient cooling)

**Stabilizing Temperatures with a Graphics Card**

I recently experimented with stabilizing temperatures in my computer system using a graphics card as a cooling method. The results were impressive, with the internal temperature reaching a stable state within 12 minutes due to air cooling. This allowed me to fill the system with ice and aim for an even lower internal temperature than the external environment.

**Creating Ice Packs**

To achieve this, I created ice packs using freezing water in ziplock bags, which are reusable and prevent water from spilling everywhere. The ice packs were then placed inside a plastic container to protect the box from any potential moisture damage. The ice packs themselves were designed to be cold enough to hurt the touch, indicating their effectiveness.

**Implementing the Ice Box**

The ice box was constructed with space for air to pass through and interact with the ice, which was interleaved to maximize contact between the air and the cold surfaces. Additional ice packs were added to further enhance the cooling effect. I was pleased to see that the interior temperature plummeted compared to the outside environment.

**Initial Success**

Upon turning on the computer, the idle temperature of the CPU dropped by 10 degrees Celsius, reaching a level below ambient temperature. This was an exciting result, but unfortunately, it was short-lived as strange noises began emanating from the system.

**Checking for Water Damage**

I inspected the system and found no signs of water damage or leaks within the computer case. However, there was melting ice and some moisture in the box itself. I started the computer to verify its functionality, and it booted up without any issues.

**Reflecting on the Experiment**

While the initial success was promising, the strange noises and potential for water damage highlight areas for improvement. I plan to redesign the ice box with a larger, more efficient cooling system that funnels air down into ice and back up, minimizing moisture buildup. I welcome comments from viewers on this concept and any suggestions they may have.

**Conclusion**

This proof-of-concept experiment demonstrates the potential of using ice packs to cool a computer system. With further refinement and improvement, this method could be viable for maintaining lower temperatures than ambient conditions. Thank you for watching, and I look forward to sharing more videos like this one in the future!

WEBVTTKind: captionsLanguage: ennow as recently watching a video by an awesome channel called major hardware if you're watching major hello in the video he takes an air cooler and then builds like a perspex box around it and then via magic attaches a bunch of liquid cooling things to it and then turns the air cooler into a liquid cooler it's actually a really cool video series I'll have it linked in the description below if you haven't seen it yet and go check it out and I thought this was really awesome I also want to make air cooling better somehow but there were two things about his implementation that makes it difficult for me the first one I am NOT handy enough to make perspex into a watertight thing around an air cooler I can't do that so I'm gonna have to use a material that I'm more comfortable with which is well cardboard something that's featured quite a lot on this channel and then the second thing that I wanted to do was cool the entire PC not just the air cooler but that seems really difficult so they're on a completely unrelated day watching an unrelated video of people making DIY air conditioners out of cool boxes I realized that's the way I need to do it I need to cool the air before it goes into the PC this may be quite an inefficient way of doing it but it looks awesome so then I got a cardboard box and some ice and fans and well this is what happens now the idea is fairly simple I'm going to take this box and I'm gonna attach a fan to either end so that air gets pulled through and then I'm gonna fill it up with ice so that hopefully it cools that air and cools down the entire system although I do have a couple concerns with this the first is well the size of the box and the reason this is a concern is well it limits the amount of ice that I can actually fit in here and it also means that the distance from the one end of the box to the other end of the box isn't that big so there's not going to be that much time that the error is actually going to be exposed to the ice but this is a bit of a test run so I'm just kind of trying out the proof of concept to see if this drops the temperature of the entire system so let's attach these fans and they're RGB so that I guess makes it better we're going to attach these fans and then we're going to fill it with ice ice and see how it goes and there we go we actually have the fans attached on either side and as you can see here I've even cable managed slightly now it's very clear oh it's actually it's actually upside down it's very clear that this video is sponsored by Corsair actually Corsair if you're watching this hint hint so now I just need to wait for the ice packets to freeze that I'm gonna fill this up attach it to the guinea-pig PC and we're gonna see what kind of temperatures we get now before we get that actual contraption going let's have a look at what I changed in the PC to facilitate this whole process so I've actually switched around the direction of the airflow because it's a really easy vent to get access to in the back as supposed to the other side which is yeah it's it's a difficult funnel so these fans are now exhaust this fan is an intake this fan I've actually disconnected and I'm gonna close this off so that we have a very straight airflow through here I've attached my temperature probe in here which will hopefully give us an indication of what temperature the air is that comes into the case although I couldn't get it directly into the path of the airflow so that may be fairly useless as you can see I've actually reversed the fan on the air cooler as well and then I've kind of fed all of this stuff out of here so that I can supply power to the fans and more importantly power to the RGB now I'm actually gonna place the case flat down so that it's going to be easy for me to align this fan with this fan here and then we're also going to not block off block off that airflow what did you do today honey oh I don't know I just sellotaped a bunch of fans screwed to a box onto a PC case and then filled it with ice that's a completely logical thing to spend your time doing but there we go it's it's a completed configuration now I've kind of taped off around which is really it's I had to do that but it's still gonna be very irritating because I'm gonna have to detach it to open it to put ice in there because there's no actual ice in there at the moment because I want to do a control test obviously so that we can see how much of a temperature difference it makes but it actually kind of looks surprisingly badass what I've also done is I've got the temperature set up here so we have the temperature of the intake and of in the actual case and as you can see it's a bit hotter inside than it is outside let's turn it on and see if the RGB and stuff actually works and if the PC doesn't hate me yeah I mean there's a nice purple glow to it now and the PCs booted which I don't know why it wouldn't boot but everything's working so I'm going to do a control test with it just like this and then we're gonna fill it up with the ice and then we're gonna see how it goes okay so we're coming up on the 20 minute mark here and as you can see everything stabilized about with the graphics card as well everything stabilized about 12 minutes ago because it's all air cooling so it means that temperatures don't take that long to stabilize but so now we're gonna fill it up with ice and the goal here is to get the internal temperature as far below the external temperature as possible now these are the actual ice packs in questions so this is kind of what I ended up going with and it's freezing water in ziplock bags so that while they're reusable and that water doesn't go everywhere it's a camera strap and so that water doesn't go everywhere and destroy the box because I do want to use it for a different platform as well so I'm actually gonna as you see here I'm gonna stack them like this and I'm putting plastic in the bottom of it again so that so that the water doesn't actually damage the box if there is any liquid that kind of perspires off the ice now these ice pockets are actually so cold that they hurt the touch so I think it should have a good effect on the temperatures one of my concerns here is that it's going to be really difficult for the air to actually pass through here but there's quite a bit of space on the sides so it means the air coming in here is going to hit the actual ice be pushed around it and it means that it's going to have to interact with the ice and these plates are interleaved like this so there is actually space in between them as well so let's see how well they actually affect the performance I'm going to add a couple more now this is so crazy I literally just turned the PC on and the interior temperature has already plummeted compared to the rest compared to the outside temperature and then for good measure I also put a blanket on to help insulate the ice in there so that it doesn't melt that quickly and then look at the actual idle temperature is already down 10 degrees Celsius on the CPU it's it's pretty exciting because the idle temperature is actually below ambient at this point okay so I've actually had to abort mission because it started making weird noises now I can't feel any water anywhere so I don't think any water got into the PC but I'm gonna have to check it out because the sounds were really weird and it's not something that it made at any point during the testing up until now as you can see there's a lot of melting going on here and there's actually kind of water getting everywhere in the box but it's just in the box so I hope none of it actually blew through into the case but I think we're gonna be okay so as far as I can tell no actual water got into the PC so I think on that front we're good let me actually start it up to see if it still works yes it boots so we should be okay and just like that I think it's kind of sure that the concept works because it was briefly glorious when there was a below ambient idle temperature on the actual CPU which is I honestly think quite a win I just need to work on my actual implementation of the actual ice cold air intake into the PC so let me know in the comments section below how you think I should change the design of the ice box to a prevent moisture from getting into the PC and B increase the performance so that the drop below ambient is even bigger now my main theory at the moment is that I think I should get a bigger cool box where I funnel air down into ice and then back up so that the air actually comes straight out of the top hopefully that will help prevent moisture coming up with it don't know if that's how physics works or anything but that's kind of what I'm going with again let me know in the comment section below what you think about this idea and with that it brings me to the end of a fairly successful proof of concept and terrible implementation if you liked the video do like and subscribe to the channel for more videos like this one I've got a video coming up where I'm going to build a PC in that box so that's quite
