"OCZ has done everything they can to make sure you have what you need to install the block. Also rather than cheap plastic barbs that you get with some blocks, this one comes with nice nickel plated brass barbs. And the OCZ Hydroflow mounting system is very very good. The OCZ Hydroflow water block is a great package in a low restriction design that's great for multiple block loops. It includes one of the most complete and quality accessory packages I've seen, and has a simple and sleek look. In addition the mounting mechanism ensures consistent and accurate mounts by all users and prevents the possibility of installing the block wrong. It's an extremely nice block that keeps my Q6600 @ 3.6Ghz and 1.47Vcore at under 51C under load at 21C ambient, this is something my air cooling just could not do. Furthermore, it appears additional performance may be had by simple increases in mounting pressure."

"The OCZ HydroFlow represents everything we've come to expect from OCZ - a high quality product, great performance and outstanding finish. Almost all the hardware needed to install the waterblock in your system is included. When it comes to performance, the HydroFlow is certainly no slouch either. Yielding better results than any top-of-the-line air cooled heatsink and fan I have tested, the OCZ waterblock will make a nice addition to any water cooling system. OCZ definitely wins in the appearance department, at least where the AMD bracketry is concerned. Price is another area where the HydroFlow really shines. If you're willing to maybe give up a few degrees of cooling for better looks and a much lower price, check out the OCZ HydroFlow HF-MK1."
