Watercooling is one of the most popular activities in the enthusiast community. Most will watercool for aesthetics and Internet points while others may build elaborate loops for the thermal benefits. Whatever your reason your choice in components can have a profound impact on how everything works together and even how efficient the loop is.

In this review I'll be looking at the Pacific W2 CPU Water Block from Thermaltake. This block can be purchased from the TT Premium online store and is currently one of three CPU coolers they have available. The block is designed for fit all modern processor platforms with included hardware for LGA 2011 and AMD. You will get LGA115x hardware installed from the factory.

The Pacific W2 waterblock features a very traditional design with a single inlet and outlet. The holes are G1/4? thread and will accept a wide variety of fittings and barbs depending on what your build requires. Pictured here are the hardline fittings from Thermaltake. These support 16mm OD tubing and are quite good.
