i was wondering if this would work because in my country it is very hot and really not care about the electricity bills in the air conditioner. if i can use the Air Conditioner to cool the Radiator just the RADIATOR Will it work???
After reading all the responses, and have actually used an AC unit to cool my computer with direct air porting to the computers intake not by way of radiator, here's my 2 cents on the subject.
First of all, yes it will work, the radiator cold capture is a good idea, not as well as you may imagine but will work.
The not as well is because an AC unit cycles the compressor, meaning there will be build up time period of very good useable cold output air, then it gradually gets warmer as the cooling coils equalize down to the compressor cut in point again.
You will need to insulate the tubing distance from the computer to the radiator at the AC output.
The air coming from the AC unit itself is always going to be cooler than the mass ambient room temperature, but with the CPUs supplied heat to the loop an equilibrium point will still occur in the loop and it will be below ambient, to some point.
Possibly not as much as you may be hoping for, but enough because anything below ambient is good, but don't be concerned with the thoughts regarding condensation worries as I don't think condensation will be a problem for this cooling idea at all.
I run peltier chilled water cooling and condensation doesn't begin to form where I live until 15c below ambient and I don't see you being able to go that low with your AC unit, simply because of the AC cycling.
How far below ambient you'll be able to go is a test you'll have to learn for yourself, I would leave your cooling fans on the radiator to assist pulling the AC air through the radiator to assure a constant flow of cooled air through the radiator at all times.
Sounds interesting, Let us know your results? Ryan
