The GPU-220 is a general-purpose block with a 0.5mm microfin internal structure. The cooling area footprint is 45mm x 45mm (1.8in x 1.8in). Revision 2 includes a new acetal bracket and mounting hardware for higher contact pressure and performance (in addition to the original mounting hardware).

Materials include a copper cold plate, brass top, anti-corrosive nickel plating, and EPDM o-ring. Works with G 1/4 BSPP (parallel) thread fittings. Redundant side and top inlet/outlet fitting sockets allow for more flexibility during installation. Two fitting socket plugs are included.

The new acetal bracket mounts diagonal hole distances from approximately 69-87mm. The alternative swinging metal bracket arms accommodate diagonal hole distances of about 50mm to 82mm.

Liquid Coolants

Koolance's product warranty does not cover the use of 3rd-party coolants, coolant additives, or corrosion. Koolance LIQ-702 or LIQ-705 coolants are strongly recommended to help avoid issues with mixed metals or biological growth.
