TEC cooling a shuttle?

sounds crazy, but do you think it was to be possible if you added a small box to the top or side to hold the rad and pump and then just have the PSU off to the other side of the case?
 
oh now you are just egging me to do it just to prove my craziness!


what sort of suppiles would I need for that size, I dont care if I need to make a whole seperate box or something... but I would prefer just 1 120mm RAD so it can hang off of the back.
 
ok, I am actually thinking of doing this, but I want to know what a good 80 or 92mm radiator is, so I can mount it from the back, and actually have a DVD drive :p
 
ok, I have one question before I go spend all this money, is it possible, or will the thing go up in flames?
 
As long as you can get a waterblock on the CPU and get the tubes out of the chassis then its possible. I wouldn't go overkill on the TEC, just find a 120mm rad and see how many watts of heat it will dissipate, then find a TEC that's rated around that wattage. Make sure the waterblock can handle that wattage too. I'd probably stay around 200 watts, but its up to you. As for the power supply, you should use a seperate one, maybe an old 300w if you have one laying around. Look at how much amperage the TEC will draw off of the 12 volt line, and then compare it to the sticker on the side of the power supply to make sure the power supply is able to deliver that amount of current. The supply in the shuttle definately won't be enough. if you got a dc pump you could run that off of the power supply too, that way you only have one plug going to the wall.

The only other thing to worry about in a shuttle is condensation. Make sure you insulate the TEC well with neoprene, as well as the back of the motherboard, and use plenty of dielectric grease around the socket in case anything does get wet. you do NOT want water getting all over your expensive components.
 
a single 120mm rad it nowhere near enough to cool a pelt cooling rig. not by a long shot.

as for what power of pelt to use: at least double the expected heat output of your proc when it is overclocked.

as for fitting everything: you would need to house a dedicated 12V supply and at least a 2x120mm fan/rad combo in that second box of yours.

to continiously supply enough current to run a pelt, you would either need a big-ass ATX PSU, capable of delivering better than 20 amps from a single 12 V rail, or a proper meanwell 12V dedicated.

you need room for a good sized pump, and fat tubing as well.

i think that with the second box, it's totally doable, however a that point you are at about mid-tower size anyway, and things will be QUITE crowded if you need to reach in and change anything around afterwards. in my own build, just clearing the CMOS is a 20 minute undertaking, sometimes. :(

ow. ok, maybe I am just gonna go straight watercooling with 3/8 tubing.
 
pelt cooling a GPU is much easier, and can give good temp gains without going all crazy with it. it's CPU cooling that is quite difficult.

in a full sized system, it is often possible to use a ridiculously high output ATX PSU to power both the computer and an 80 watt pelt for the GPU. i don't think that there are any shuttle supplies in that output range, but i just thought that i would mention it.

at that power level, you can usually cool CPU, pelt and GPU with a normal two fan rad.
 
yeah, I think they make 350watt shuttle PSUs now, but with so little stuff I would actually think you might be able to do that without a rediculous system.
