The X1600 PRO if you do not already know, run off the RV530Pro Graphics Processing Unit (GPU). This GPU is based upon the 90 nm production process, which is the norm for majority of today’s GPUs. With such a specification, high clockspeeds are ensured. No doubt the fillrate for this generation of GPU has levelled-up by a notch.

Zooming in, we find our GPU produced on the 50th week of 2005.

Let’s take a look at the cooling solution offered.

A 60 mm fan and with a extruded aluminium heatsink creates a quiet-running cooling device. We could only detect a tiny whoosh of turbulence under 3D load, else the heatsink fan keeps itself acoutically invisible. Thermal pads transfer heat from the gDDR2 modules to be spread by alumnium heatsink base.

The heatsink has been mounted with silverish thermal paste. It may look like Arctic Silver at certain angles, but the viscousity is sure different.

Nichicon capacitors and encapsulated inductors are used for Pulse Width Modulation ripple filtering. Extensive use of Surface-Mount ceramic capacitors kick out high frequency nasties in the environment, ensuring stability.
