Sapphire Radeon HD 4670 Ultimate 512MB video card review

If you're in the market for a passively cooled GPU as part of a low noise or silent PC build, then Sapphire have been one of the primary contributors to this area for some years now, launching a number of suitable graphics boards over various generations of ATI architectures as part of their "Ultimate Edition" range of parts.  Even as GPUs have been getting ever more powerful, and potentially harder to cool with it, Sapphire have stuck to the task of providing the fastest passively cooled parts possible, normally targeting the mid-range as the sweet spot of performance and silence.

Today we take a look at the latest addition to the Ultimate family which continues this tradition almost exactly, making use of AMD's mid-range Radeon HD 4670 and equipping it with a passive, completely silent cooler.  Just how effective is this solution, and what does it offer users looking to build a silent or near-silent system?  Let's take a look.
