Be quiet! is no stranger to closed-loop liquid CPU coolers. In fact, I still use the company’s previous all-in-one cooler in one of my own systems.

Be quiet! has continued its trend of standing out from the crowd with its latest AIO design, as the new Pure Loop features a pump system attached to the tubing rather than being integrated into the CPU block. How does this approach affect thermal performance? Let’s find out.
