Most closed-loop liquid coolers are unexciting, but that’s not true for today’s Swiftech H360X3 that we’re reviewing. When the vast majority of CLCs on the market are made by Asetek or CoolIT, it immediately makes companies like Swiftech interesting for their clever solutions to bypass Asetek patents or attempt to improve upon long-standing cooling designs. Most companies buy their CLCs from Asetek and CoolIT, including every single CLC made by NZXT, EVGA, Thermaltake, and Corsair, but some make their own or find alternative suppliers. The Swiftech H360X3 is a semi-open loop that’s easily expandable for water cooling, but also includes clear tubing with dyes for more custom-tuning without venturing into full open loop territory. Today, we’re testing the H360X3 to see how it does versus plainer solutions.

For the basics, the Swiftech H360X3 AIO – or CLC, as we continue insisting – should be priced at around $165 for the 360 variant, or $140 for the H240X3. The series includes three dyes (red, green, blue) to accompany its pastel white coolant that’s pre-filled.

On December 5, we broke news on Asetek's Cease & Desist order sent to AMD, pursuant to the sale of its liquid-cooled R9 Fury X video card. Asetek previously won a suit against Cooler Master USA for its closed-loop liquid cooler products (CLCs), to include the Seidon, Nepton, and Glacer (Swiftech-supplied) lines. The patents primarily discussed are 8,240,362 and 8,245,764.

By judge and jury, CMI USA (Cooler Master USA) was found guilty of patent infringement of the pump-on-coldplate design and ordered to pay 14.5% royalties. Inability to pay-out on its ruled dues ultimately saw a royalties percentage increase to 25.375%, followed by banishment of all affected Cooler Master CLCs from US markets.

This article fully details the relevant legal history of liquid cooling companies, including the rise of Asetek & CoolIT, their patent lawsuits against one another, the recent lawsuit against Cooler Master, and the C&D against AMD's R9 Fury X.

Liquid cooler manufacturer Asetek, the company that supplies many of the industry's best-known coolers by Corsair, EVGA, and NZXT, saw victory in a patent infringement case against Cooler Master (CMI) in 2014. In that trial, the jury awarded Asetek a 14.5% royalty on all Cooler Master liquid coolers sold in the US.

Closed-loop liquid cooling (CLC) supplier Asetek has agreed to settle its ongoing patent infringement lawsuit vs. CoolIT. CoolIT, also a liquid cooling supplier, allegedly infringed upon Asetek's patents (8,240,362 & 8,245,764) that effectively lay claim to liquid pumps mounted to the CPU cooling block.

CoolIT is the most recent in a string of action imposed against Asetek's competitors, a list that includes Cooler Master and Swiftech.

Update: CoolIT has provided a statement, found below.
