About us

PrimoChill

Custom watercooling since 2002, from Boise, Idaho. We design our own fittings, tubing, reservoirs and coolant, and stock the parts a custom loop needs around them.

Where it started

PrimoChill started in a garage in 2002. PrimoFlex tubing came first, in 2003, followed by PC ICE coolant in 2005, the Ghost compression fitting in 2008 and the CTR reservoir in 2012. Revolver SX fittings arrived in 2013, Advanced LRT tubing in 2014, the Wetbench test bench in 2016 and the TRUE coolant line the same year.

What we sell

PrimoChill fittings, hard and soft tubing, reservoirs, coolant and bending tools, plus Bykski and Granzon water blocks for GPUs and CPUs, radiators, pumps and AIO kits.
