Overclockersclub nous propose un test de la carte graphique Sapphire HD4850 Dual Slot Heatsink, comportant un dissipateur double slot. Les résultats sont assez convainquant tout en sachant que coté Overclocking, on est assez limité.

" It's time to buy that shiny new addition to your gaming rig to replace the well-worn video card that just can't keep up with the latest video games. You've been eyeing the ATI HD4850's and the performance looks just right for the dollars available in your shrinking bank account. There's just one thing that keeps bothering you - the temperature problems that you have been reading about on this series of cards. Sure there are utilities that can adjust the fan speed manually (finally), but you want something better. Actually, you need something better to cool the card but there is that lack of the green to get that something additional - an aftermarket VGA cooler."
