Watercooling is a huge part of the enthusiast culture surrounding PC hardware. Modders and Gamers look to water cool their systems for aesthetics and silent computing. 

Overclockers UK has a huge range of watercooling products from the very best brands available including Bitspower, Primochill, EK Waterblocks and XSPC, enabling you to build your own custom water cooling loop. 

The Largest Range Of Premium Quality Water Cooling Components

  • Our range of Radiators covers all bases from low FPI, high airflow radiators that are optimised for silence, over to high FPI performance radiators designed for maximum cooling.
  • No watercooling system would be complete without a reservoir and we have them in all shapes and sizes. From bay reservoirs to tube and pump mounted solutions, we have you covered.
  • Our pump range lists the most popular and reliable units from Liang and other performance brands ensuring you have a trouble free and reliable experience with your watercooling solution.
  • We stock hundreds of CPU, GPU, Motherboard, Memory, and HDD water blocks. The vast choice will enable you to choose the perfect water blocks for your water cooling loop.
  • In addition to this we have a large range of addons and accessories in our watercooling catalogue, from specialised fittings to acrylic tubing, that will allow you to make your cooling system just how you want it.
  • Overclockers UK also carries a massive range of performance and specialist coolants from tier one brands such as Mayhems, where research and development lead to excellent products.
