Asus X1950 Pro Crossfire (EAX1950PRO)
Published: 13th November 2006 | Source: Asus | Price: |The Card
Asus has implemented their own cooler on their X1950 Pro. With a sleek white design topped with a nice looking mesh on top Asus have done a good job in the design stakes. The heatpipe peering out of the top of the cooler gives this reviewer some confidence in Asus' cooling solution: heatpipe's are a good thing as far as graphics cards are concerned.
The Asus X1950 Pro features Dual DVI connectors and the card also has HDCP implemented as standard. This is excellent news for those wishing to purchase this for the future as Vista will eventually require a card with HDCP coded into it.

As stated previously, Asus have implemented their own cooling on the card. The cooler features a fairly compact fan that draws air over some fins connected to the heatpipe. Heatpipes are very efficient at drawing heat away from area's that need to be cool and so it's good to see Asus implementing this.
The downsize of this cooler is that it does suffer from a whooshing sound when it's under full load and if you have a particularly quiet system you may notice a slight whirring at idle. This is not to say it is a loud cooler, but if you are a totally silent PC user then this card will get mildly annoying.
I loaded up Rivatuner to check the temperature of the cards in Crossfire and this stayed at a very nice and cool 41°C at idle and 57°C load (ambient 23°C).
All in all it's a nice solution from Asus and certainly would make your case look pretty neat with it's understated looks and aggressive heatpipe.
