This is my setup with a passive rad made with 4 heatsinks epoxied together... work in progress(still have to make it look better, mabe paint it black) Other than that it keeps my water around 39 full load and very close to ambient at idle.
barton 2500 to 3200xp
o the sides are acylic pieces sealed on all sides with silicone( lost of it)...with the inside of the heatsinks formed in a maze channel desing to get the water flowing past the half drilled holes on the top and bottom heatsinks...
