Running a Radiator outside?

Alright, I'm a college student with alot of free time and a few bucks to spend. I have an idea that I want to try, but want to be sure I won't run into any problems. I have a PolarFlo TT series pump and a dual 120 heatcore from a jeep that I am using. I want to see what happens to my temperatures if I put my radiator outside on my windowseal with 2 hoses running the distance between my computer and window(about 10 feet). My question really comes in here, Do I put my pump before the large loop or do I put it after it? Or would adding a second pump to the loop be helpful?

This is really just for novelty and I figure I can drop a few degrees off my temps....or even a whole digit.
 
10 feet away means 20 feet of additional tubing, not to mention that if you are not running fans on the radiator (or live in a very windy area) the cooler air outside wont give all that much more of a performance increase since it will be just sitting there and not moving through the radiator. The 20 feet of additional tubing, depending upon the diameter 1/2 or 3/8" will also add more restriction to the loop, which will reduce flow and therefore the effectiveness of your waterblock.

If the computer were right next to the window, or a bit closer, and you had a way to get a fan out there as well to make sure that you have air flowing through the radiator then you might see some decent performance gains. Not to say that you wont get performance gains with your current set up (hard to tell with all the variables), just saying that if you do they likely wont be very much.
 
Would I get any benefit by running insulated ducting (4" ID) from my window to the case with a 120mm fan at the front to suck air in? I'm really just looking for novelty here.

sure, you'd be putting colder air through your radiator, right?
But you'd also be running cold air into your room... I say go with your first idea, I've actually wanted to do that for a while (run lines to an outdoor radiator.)
 
run lines + power wires to your window, and get teh biggest, most annoying fans you can. Then, get the biggest / most annoying / high flowing pump you can, and set up your loop with teh pump outside as well. Outside air will then provide cooler air to the rad as well as cool off the big giant pump (get rid of some heat that those gnarly units are supposta put into the water) that would negate any flow loss through the long tubes.

Then, you have an uber-high cooling system without the noise... mmm... noiseless.

BTW, make sure you do push/pull with the fans (big gnarly deltas or maybee even 120v fans) on a triple 120mm core... or one of those quad-120 deisle cores that someoen was posting about a while back.
 
Simply placing the pump in a cold environment does not lessen the amount of heat it releases into the water. However if you had a large enough radiator, in theory the extra heat can be handled without any ill effects. But as was shown by cathar, once you get to a certain pump size the amount of extra heat it pumps into the loop would require a MASSIVE radiator to make any type of a performance gain.

(for the md-30 to beat the md-20 you would need like 2 triple 120mm cores or something)

Actually, having the pump in a cooler environment would mean that more heat probably DOES leave into the environment rather than into the water, in comparison to having the pump indoors. Maybe not an appreciable amount considering the radiator is also going to be in the same environment... but just a technicality.
 
I am more concerned about this working to well in a very cold evironment. If it is 5 degrees outside and the loop is working well, you could have a condensation problem.
 
Condensation is going to be a problem, unless you live in a dry area.

Run the tubes inside the foam ducting you can get at the Lowe's/Home Depot/etc.. as far as the MB goes... luberex on the pins, conformal coating on the back, maybe surround the block with neoprene.
 
But what about when summer comes around? Is it really worth all the trouble for a system that's only worthwhile part of the year?

Still though, 5 degree air should give you some sweet temps.
