Hello again!

I had an idea on using a fridge as a case. I think it's a great idea, since it produce alot of icecold air around the components. Now, my idea was to cut out the side on the chassis, where you put the components on. And put it in the fridge/freezer. And maybe cut some holes in the front, and put some fans that can push out the air. And the fridge push cold air in. But I was thinking, does it get muggy in there? If so, isn't that dangerous for my hardware?
(Edit: A colleague at my work, said that it won't get muggy inside the fridge, if I keep it closed all the time. If I open the door, it'd can get muggy).
If not, I was thinking of setting a watercooling in the fridge where the freezer itself is. So it gets extra cold, and will cool down my components even more.
The noise? Yeah, it'll be really noisy, but I don't care 'bout that. Even though I'll set some Nexus DampTek Noise Absorption Material around the freezer/fridge inside (maybe outside too? If that helps).

Noise Reduction:
- DynaMat
DynaMat is actually for cars. But in great use for this too. Reduce vibration and noise.
Price: 67$
- DampTek
This will reduce noise.

I will cover the walls inside with these materials. Maybe on the outside too?

I'm not using the fans for cooling, but to move the air around in the chassis. I'll be using between 7 to 10 fans for optimal airflow around the chassis. And some extra cooling?
Well, I'll put some fans on the heatsink though, for extra cooling.
My colleague said that I won't be needing to cut holes in the frontdoor and put some fans there to push the air out. The fridge itself will do the job.

The heatsink system:
Motherboard: Thermalright HR-05/IFX
http://www.thermalright.com/new_a_ [...] 05_ifx.htm
CPU: Thermalright Ultra-120 Extreme
http://www.thermalright.com/new_a_ [...] VzaWFzdA==
VGA: Thermalright HR-03 GT
http://www.thermalright.com/new_a_ [...] VzaWFzdA==
RAM: Thermalright HR-07 Duo
http://www.thermalright.com/new_a_ [...] VzaWFzdA==
MOSFET: Thermalright HR-09 S/U (type 1)
http://www.thermalright.com/new_a_ [...] VzaWFzdA==
I don't know if I'll be using only heatsinks, or a combo of watercooling and heatsinks. Maybe you guys got experience enough to tell me what would be best to use. My opinion is to use heatsink only. Since the cold air that flows around will cool down the heatsink even more. But when I'm thinking of to connecting the watercooler to the freezer, I'm thinking that would be even more efficient.
Price: 256$ (All heatsinks)
Price: 117$ (MOS, RAM & MB)

The watercooling system:
- Swiftech H20-220 Ultra + Water Cooling Kit http://www.xoxide.com/swiftech-h2o [...] -plus.html
If I'm gonna use the watercooling. Then it'll only cool down the CPU, VGA and maybe the MB? And use heatsinks on the rest. But I was thinking, maybe I can make the fridge itself cool down the watercooler, so I get icecold water and air!

Yes, it is expensive, but is it efficient? And if it is efficient, is it efficient enough to be worth the money?
We'll see when I've built it up. Just need to order the products first.
Still, I'm wondering if I should go for Fridge & Heatsink, Fridge, Watercooling & Heatsink, Freezer & Heatsink or Freezer, Watercooling & Heatsink?

So what do you guys think about this solution for chassis cooling?

Kind regards,
Nymph.

Expensive and incredibly inefficient.
A better idea for the cost would be phase-change cooling.
In a fridge you'd have massive condensation problems, you would need something to keep the humidity low, otherwise you woudl ruin your components.

That's what I also thought, but my colleague told me that the humidity will be low, if I just keep the door closed. And I don't need the door open, only when I'm gonna change parts or so, but I'll just shut everything down before opening the door.
But I'm gonna test this chassis solution on some crappy old parts, and see how it'll work out.

But inefficient? I don't think so, since you can control the temperature on the fridge. I was thinking something around 5-10 celcius, and have 7-10 fans to move the cold air around. Plus, I'll be using heatsink and/or watercooling.
So, I think this will be very efficient! But we'll see.

Kind regards,
Nymph.

I think you really would be better off with phase-change cooling. That's what I'm using on a couple of FX-74's and it works brilliantly. Cost a whole heck of a lot less than your proposed system and I don't need to worry at all about condensation. That's going to be your biggest problem. Just keeping the door shut won't help as fridges aren't completely air-tight. Think about it, if they were air-tight you wouldn't be able to open the door easily when the outside air-pressure rises....

I think a fridge computer would be fantastic!

...Or maybe the world first quad core freezer??

Not a good idea.

Actually, thinking about it... why not just hermetically seal the whole room and mount the fridge/freezer - minus door - in a whole in the wall. Instant cooling for all electronic cooling in the room

If you want a really cheap cooling solution try Tom's oil cooled PC. Watertight your case, take off all the fans and fill it up with cooking oil. Works a treat apparently.

Wouldn't that write off the guarantees on ALL the parts though?
RyaN

You've gotta point there. But I'm sure it really is air-thight, since it got a very thick rubber lining around the door that keeps the air out. I guess? Or that's what I've been told.

Kind regards,
Nymph.

This wouldn't work in the long run I fear, the heat your computer would generate would heat up such a small area incredibly quickly in comparison to the cooling action of the fridge itself.

First off, he didn't have any airflow at all. Secondly, you can turn up or down the temperature, wich I will have at 5-10 celcius. I'm almost sure that this will work. But we'll see when I've rigged it up.

Kind regards,
Nymph.

Well, I'll turn the temperature at 5-10 celcius, with 7-10 fans moving the icecold air around the case. And having heatsinks or/and watercooling. I'm almost sure that this will work. But we'll see.

Kind regards,
Nymph.

How air-tight it is or isn't depends on the fridge, surely? (where are fridge experts when you need one??) Trouble is you need contact cooling, rather than convection cooling, on the hot parts. It would be better to use the fridge to cool say 20 litres of water and run the water through a water cooled system.
Ryan

But if I sealed the whole case, how I'm supposed to get to my components?

Well, I'm not actually looking for a cheap cooling solution. BUT! If everything goes to hell, I still got the heatsinks and/or the watercooler. Then I'll just throw the fridge away, and use a normal chassis, wich will be Cooler Master Cosmos Silver.

Kind regards,
Nymph.

Indeed, and I guess these ones is. But not completely sure.

Yeah, that's what I've wrote.

If I'm gonna use a watercooler, I will try to get the fridge to cool down the water.

Kind regards,
Nymph.

Interesting idea. Don't think it can work though for reasons already mentioned.

I'm pretty sure most any fridge won't be efficient enough to lose all the heat a pc generates.

Give it a try and let us know how it goes.
