Pues le mande un e-mail a artic cooling para ver si 9550 era compatible con ati silencer1 rev.2 y me han respondido esto:
Dear Rafael
Thank you for your email and interest in ARCTIC COOLING.
Most probably an ATI Silencer 1 rev 2 would fit your board.
However we always recommend our customers before purchasing to go to our website
http://www.arctic-cooling.com and print out the Height Restriction Drawing for this cooler.
Go to VGA cards / ATI Silencer 1 rev 2 - under Compatibility print out "Height Restriction Drawing".
It is 1:1 so you can place drawing on your board to compare were mounting holes are and if there is potential interference with any other components.
If drawing corresponds you can go to "Where to Buy" to find a retailer nearest you.
Best regards
ARCTIC COOLING.
Pero no me entero de na, a ver si una manilla. Y tb si alguien sabe algun disipador para una radeon 9550 de 256mb XpertVision concretamente.
Saludos y Gracias
