Garage sales! Find one with the older style freon like mine. i can get my coolant to -20 deg. C or better with it under full load! Chip is putting out 60~70w.

like any paticular modle or manufacturer i should go for......and also i posted in another thread about how so people i know have done this and their all died within 6 months of starting up......the guy said it had something to do with amps???

Well if you use one without a condensor then I believe you will toast the fridge. You need a fan running on your condensor! I have a huge radiator style condensor on the back of my fridge. Here is a pic of it!

What about just puttin your resivor in a mini fridge would that drop your temps alot

Fridges are designed with certain storage temps in mind. The type with a freezer box in it is designed to keep food in the freezer at around -22C. The other common type is the ordinary fridge with the evaporator plate on the back wall. This is an ordinary fridge designed to keep food cold but not frozen and the target temps are around 0C-5C. The evaporator is designed to go to -8 to -10C only.
You really have to decide whether you want a cooler temp say around 10 - 15C with the latter or go sub-0 with the freezer type.

lets go with the lowest temps possible.....can somebody maybe show me a link to one of these freezers so i can know sorta what to look for......

I heard somewhere that the small cooler type fridges actually have a pelt in them, just wondering if anyone else has heard this? If so a wattage from one? Just wondering if it would be a cheaper way to get high watt pelts.

I doubt it!

is there any non-permanent way to insulate your motherboard for condensation?

Simply put no. I wouldn't recommend doing a so so job on your waterproofing. one water droplet and its poof for your PC. If you spend your time to make it look good. Cut your neoprene foam with scissors and an exacto knife to fit perfectly and use clear silicone i don't see any reason to stray away from waterproofing for a permanent application.

 

[JoeCrappa]

good point. is there any in depth sites or links that talks about this?

There are lacquer sprays available from many electronic stores which are clear. I don't know brand names.

It's really quite simple. The fridge has a metal box (evaporator) at the top usually with a plastic door on it. If doesn't have that then it is not a freezer type.

For conformal coating spray, read this thread, Project X:

http://forum.oc-forums.com/vb/showthread.php?s=&threadid=66635&perpage=30&pagenumber=4

I have listed there an easy way to find the stuff, I got a 350g can for 12$ around me locally...

About the fridge system, yes, some use a peltier as a cooling device, those are real cheap, and won't do what you want.

If I were to do this all over again, I would find an old fridge, rip it apart, if it leaks, oh well, I would fill it with propane, and make my own cooler as a reservoir.

You should really read Project X thread, that has everything and more you could ever want to know about refrigeration. Best, Bill

"..hello police....i want to report a hijaking....yea these guys stole my thread and decided not to answer my question......hello helloo !@#$#!$" but thats ok i dont mind

 

[Ocelaris]

Haddy,
You can't buy a brand new fridge for less than 60$, you are correct.

You have to find a used fridge somewhere, people throw them out, and leave them out on the curb for a couple of days because special trash people have to come to pick up the fridge for correct disposal.

You also might check local colleges/universities, they sometimes have small dorm fridges for sale by students at the end of the year, or people pitching them. Check college bulletin boards, trades/for sale etc... other than that, scrounging up a fridge is hard work. Good luck, Bill

 

[Haddy]

but i real question wuz what should i look for a fridge?? is there a difference between them??
