This Bykski CPU Water Cooling Block and DDC pump combo features an electroplated copper base plate that is covered by a precision machined PMMA reservoir top and integrated DDC pump. This block fits a wide variety of current AMD processors and is designed to meet the compact structure inside ITX small form factor chassis.

The block base is electroplated to prevent oxidation. The top is highly polished PMMA with a black accent logo. A high flow design is achieved using 0.5mm channels. This creates good heat dissipation and allows for maximum performance.

It's an alright product with some relatively minor issues.

I like the asthetic and the features the product provides but it has a port blocked by a mounting **** and the pump has some strange harmonics outside of the range of 2300rpm and 2500rpm. Its 114mm in width which does necessitate additional loop planning to accommodate considering most graphics cards are around 140mm in width. Expect to need additional fittings to accomidate this product if you have a narrower graphics card.
