The Stealth block fits nicely into the pack of today’s top high-end CPU water blocks, and the aesthetics are such that it is definitely one sleek looking block and would look wonderful in just about any case setup. The block retails for about $75 USD in North America, and that sits squarely in the middle of the price range for a quality CPU water block. The accessory package is fairly standard, so the value being offered here is quite good.

In terms of performance, we saw that the Stealth has moderate flow restriction and should work well in a multiple block system setup. The pin matrix design has proven to be very efficient as we’ve seen in other instances, and the cooling efficiency on the Enzotech block certainly follows the pattern, providing some impressive performance results on a highly overclocked Core i7 monster CPU.

There are some concerns here though. The first is that there isn’t any AMD compatibility, which is very disappointing. Hot Intel chips might be more popular for water cooling, but surely there is a considerable market out there for the new hex-core AMD CPUs. And it’s not like another bracket is terribly expensive anyways. Further, why no Intel LGA1156 compatibility? LGA775 is compatible, but it’s End of Life, so why not go with LGA1156 or AMD instead?

The other issue is that the sturdier, bolt-through screws should be used instead of the EZ Retention module made from plastic; it feels cheap and flimsy. A minor design modification would also fix the issue of having the clip bolts being just slightly too short. And lastly, plastic washers should be included to help avoid scratching the finish from the spring-loaded thumbnuts. Again, this is a small and inexpensive solution where consumers will appreciate the attention to detail; it does make a difference.

Thankfully these are small issues that can be easily fixed by very minor design tweaks. The overall design, quality, and presentation of the Stealth is fabulous. It’s a gorgeous and sleek block, priced rather well, and offers excellent performance as well. It is a very good all-around CPU water block, and if Enzotech can improve the minor issues noted, they’ll have an outstanding product on their hands. For now, though, we’ll have to settle for calling it "Great".
