As with the W2, the W3 is a great block for people who run SFF systems or for those who have watercooling geared towards silence.
Fortunately, Thermaltake has designed a block that will allow you to mount two graphic cards on most SLI/Crossfire motherboards. The block functions as intended; it doesn't leak and is relatively easy to set up. Of course, it doesn't make any sound either, so you can enjoy a completely silent PC. I am glad that Thermaltake has provided a cushion with the mounting kit, it subtracts a possible area where things could go wrong.
The W3 is close, yet so far from being perfect. It has several “pro” features, such as a lapped base, or the already much-praised foam cushion. On the other hand, there are features which are less understandable – small barbs and a flimsy mounting mechanism.
Larger barbs would not only make the block popular among those with traditional watercooling systems, but also to those who cool using a water chiller – a brazed block is ideal for this purpose.
If Thermaltake would improve these aspects, I would not be afraid to give this chipset block an even higher rating, but the above mentioned prevents me from doing so.
