ATI X1900 GTThe Powercolor X1900 GT uses the reference cooling, which is a compact single slot aluminium heatsink with a copper core insert that covers both memory chips and GPU core. At reduced fan speed (2D mode) it’s relatively quiet but once you load up a game it will become quite noticeable in your system.
A naked X1900 GTThe fan speed can be controlled through
ATI Tool or
ATI Tray Tools. You can either set it to a fix value (e.g.: 50%, 100%) or let the fan be controlled automatically. From the different after market coolers tested here, only the Accelero X2 from Arctic Cooling connects directly to the fan header on the X1900 GT and thus it can profit from the onboard fan speed control.
Installation of the aftermarket coolersWe covered the installation of the Zalman, Accelero and Sytrin coolers in detail in
our last roundup, the method for getting them on the ATI card is not very different and the remarks in the last roundup still stand. The Sytrin needs the most work out of those 3, with custom bracket and plenty of screws to be fixed in place, the Zalman also needs a bit of screwing work but does so tool-less with practical thumbscrews. The Accelero X2 is made especially for the ATI X1800/X19** series and fits using the same mounting holes as the original stock cooling.

We haven’t covered the Thermalright V1 Ultra before, so let’s see how it’s installed on the next page ->
My system setup is similar to the Piotke's Test Setup picture on Page 1 of your review except my Zalman blow air directly to the back of the case.
