DIY Chiller idea

[Scavenger]

I was thinking about how to cool my tank and came up with this idea. Anyone ever try it or have an opinion if it will work or not.

What I was thinking was to pick up one of those AC/DC coolers that sell for about 50 bucks and put it in line with my system with a valved pump to control flow (keep water in cooler longer or shorter to get temp). Or use it as a top off container. I think this will help keep the temp down but I am curious if the cooler would burn out under the constant load or not.
