The installation of the cooling system on the graphics card went smoothly. Like in the Zalman TNN500A review I used a RADEON X800 Pro from PowerColor:

It’s easier to install the cooling system before you insert the card into the AGP slot. Even without any guides or manuals you should do the installation without problems. The only thing you should take care about is putting thermal paste in all places where heat contact occurs. You should fasten the GPU block completely only after installing the card into the AGP slot as you’ll probably have to shift and turn the heat pipes to place them into the block on the side panel. Here’s the card with the cooling system mounted:

One of the memory heatsinks at the back of the card’s PCB is installed with a minor shift – I will put a thermal sensor there later.

So, all the system components are in their places – you only have to lay all the power and interface cables.

It’s here that I stumbled upon a problem. The mainboard I used in the testbed had a 20-pin power plug, while Zalman’s PSU has a 24-pin power connector. Yes, these connectors can be used with each other – the four “unnecessary” contacts can just hang freely in the air. But an IDE connector is located too close to the power connector on the ASUS P4P800 mainboard, so these four pins become an obstacle. So, I had to remove carefully the plastic part of the mainboard’s IDE connector:

After that the power cable went in without problems, but at the expense of one IDE channel:

To avoid this problem, Zalman should have equipped its PSU with two different cables for the mainboard.

All problems solved, I’ve got the system ready for my tests:
