Im in the process of fabricating a coil in coil HX for use as a condenser. The same way that Bazx did with his Cascade 4 and 5.

Exactly the same way he did, except i wont have a 120 litre/gallon (cant remember) barrel outside with shed loads of capacity and ambient cooling. Instead im thinking of linking it into my current WC setup (D5 + QP220)

Does the QP220 have enough grunt to keep liquid temps from getting out of control? I have two 85CFM delta's stuck to it (silence not important)

The HX idea isnt my only option, i am willing to go the standard condenser route, but that way my WC setup kind of goes to waste.

Anyway, let me know what you guys think
