Bitspower Summit EF-X CPU Waterblock @ techPowerUp
 

Bitspower has not enjoyed much success in the sector of CPU waterblocks, owing to average performance and high product cost with limited customization. They aim to change this in 2017 with the new Summit EF that promises to run at up to 6°C less than before; it will also come with top options in acrylic, nickel-plated copper, and a special gold-plated copper edition.
