The first thing I had to do to prepare the GTZ for installation was to swap out the mounting plate for the optional AM2 kit. To do this a hex key is needed (and not supplied) to remove the four corner screws. Once the plate is loose it is simply lifted off the top of the block and the new plate installed. The original Intel 775 plate uses a stamped steel design with rolled edges for extra rigidity, and the chrome finish and pre-attached spring-loaded thumbscrews give it a nice appearance. The AM2 kit looks very utilitarian by comparison; the plate is a simple piece of steel, which still has sharp cut edges and machining marks on its unfinished surface. I used my palm sander to smooth it out some prior to installation. The mounting screws, washers and standoffs have to be assembled on the plate manually. There was also no installation instructions included with the AM2 kit, however going by the guide for the Intel 775 it recommends aligning the block with the bottom along the socket edge where the ZIF lever is located, so care must be taken when installing the AM2 plate in order to orient the GTZ appropriately.
Prior to installing the block in your system, the entire loop should be assembled and tested for leaks. Because the supplied MCP355 pump is limited to 3/8" fittings, Swiftech 3/8" Norprene tubing with SmartCoils was used. This is the tubing originally included with the H20-220 Compact kit, although a third piece was required as now the pump and block are separate components. The MCR220 is a dual 120mm radiator with integrated reservoir top and is also carried over from the 220 Compact kit. When installing a new heatsink / water block, I always like to double check the thermal compound pattern to make sure it's getting nice, even coverage.
With everything installed in my Mountain Mods case it's time to fire up the system and run some temperature tests.
