Coolink GFXChilla VGA Cooler – Cooling The Radeon HD 4850Sat, Jul 05, 2008 - 12:00 AM
The two large, low-profile 80x80x10mm fans spin at 2,000 RPMs and produce just 18dB of noise. We were informed by Coolink that the GFXChilla’s 80x80x10mm low-profile fans can be replaced with standard 80x80x25fans, which, due to their bigger height, can produce higher levels of airflow. The fans air paired together and end at a single 3-pin fan header. The Coolink GFXChilla comes with a 3-pin to 4-pin molex adapter, so it can either be plugged into a motherboard or directly to the systems power supply.
Flipping the GFXChilla over we see the four 6mm thick heatpipes a that transfer heat away from the copper base that will eventually cover the GPU. The Coolink GFXChilla comes with a protective sticker over the base to keep it from getting scratched and corroding before it gets attached to the video card.
With the sticker removed we found a flat copper base that had machining marks in it. This heatpipe cooling design should be familiar as nearly every CPU cooler uses this method. It only makes sense to use heatpipes to better cool video cards.
