Xigmatek Prime Review
Up Close: Twin Fan Configuration.
It's when we add the second fan that this heat-sink really begins to step out of the shadows and give a bit of a hint as to what it might be capable of. Don't forget these aren't little 120mm fans here. What we have is two 140mm fans in a push pull configuration (well we do if I've put them both on the right way round, don't laugh, it's very easy to get it wrong). Unlike the primary fan the second fan is a standard 3 pin affair but identical in all other respects.
I have to be honest when I first saw the bungee method of attaching the fans I thought it was more than a bit cheap and to be frank a bit naff and inelegant. My first impressions weren't in anyway allayed when I made my first attempts at attaching them, being very worried of snapping them or worse still bending the fins on the heat-sink. I have to say my fears were unfounded as both the bungees and the heat-sink are a good deal more resilient than I had given them credit for, and although it can't be denied there is a definite knack to using them they are on the whole a very ingenious piece of simplistic engineering. I'd actually go as far as to say that having encountered many and varied forms of attaching fans to heat-sinks, I am now something of a convert to the bungee technique
