Installing the Xtreme GTX Pro is quite simple but requires a little bit of test fitting. The included instructions are simple and clearly marked, stepping you through the installation of the heatsink but not removal of factory installed heatsinks. Which VRM heatsinks are for which card design is also not specified, so you will have to test fit without removing backing before doing it for real.

After removing the existing heatsink the memory chips, VRMs and chokes should be cleaned to ensure the new heatsinks adhere properly. Artic Cooling recommends using an eraser to brush over the surfaces, although we found that a dab of isopropyl alcohol on a soft lint free cloth worked better to remove old adhesive reside. The GPU core also needed a little isopropyl alcohol to remove the copious excess thermal interface material applied to at, at the time of manufacture, now hardening and becoming more insulating than thermally conductive.

The first step was to mount the heatsink for the VIVO chip present on the GTX 275. This is held in by four screws, through plastic spacers. The spacers are adhered to the socket mounting holes, to help make installation easier.

Next the memory heatsinks are applied. Test fitting here is important to ensure no components are accidentally bridged by the metal heatsinks.

After installing the memory heatsinks, the VRM heatsink is applied. For the GTX 275 a single, large heatsink is applied to all three rows of VRM. No heatsinks can be fitted to the chokes, as there is not enough clearance between the main heatsink and the taller chokes.

Lastly the Accelero itself is applied to the card - or rather, the card is applied to the heatsink. Be sure to plug in the fan connector first, before screwing down the heatsink using an alternating corner pattern. Once this step is complete you are now the proud owner of a GeForce GTX 200 series with an 11" long, triple slot, triple fan cooler!
