I went to a local autojumble looking for just the same thing, most of the rads I saw were as big as car rads nevermind heatcores. Bought 2 small ones for £9 the pair, one was a rad and the other an oil cooler. I tried the rad in my last setup but I think it was designed to have air blowing through it at 60mph to have any cooling effect, didn't try the oil cooler, bought an Abyss Deep instead.

Cheers
