One of their popular line of cards has been the cards using the various IceQ-coolers from Artic Cooling. While the IceQ-coolers are really silent even when the cards are running at maximum performance, they still emit a bit of sound, enough to annoy those who want a totally silent system. The solution, of course, is to make the card passive cooled, and HIS also offers a few passively cooled cards where they have partnered up with Zalman and put a Zalman VNF100 on the cards to cool them passively. So far they have only done this to an HD2600XT card and an HD3650 card and it is therefore no surprise that they have chosen an HD4650 GPU from this generation.
The card is called the HIS HD 4650 iSilence 4 512MB and we have been taking the card for an extended spin in our testing lab to see how good is.
