The ATI Radeon 9800 Pro video card features a 380 MHz R350 graphics processing unit, or GPU, and DirectX 9 support. A passive heatsink and standard VGA fan ensure the graphics card remains cool during 3D gaming sessions.
The Radeon 9800 Pro uses a combination heatsink/cooling fan system to cool the R350 chipset. The heatsink sits directly atop the GPU and pulls heat away from the chipset. ATI integrates an 80mm VGA cooling fan into the heatsink to blow the heat away from the GPU and heatsink. The fan draws electricity from the 9800 Pro through a three-pin power cable.
In performance tests, Icronitic measured the operating temperature of the Radeon 9800 Pro at a maximum of 68.6 degrees Celsius when running 3D games. When displaying 2D graphics, the operating temperature averaged around 45 degrees Celsius.
The VGA fan/heatsink cooling system used in the Radeon 9800 Pro is robust enough to support GPU overclocking. The reviewers at Guru 3D report they were able to raise the GPU clock speed to 400 MHz without causing system instability or excessive heat.
