PCCooler brought a vast lineup of high performance air CPU coolers to the 2025 CES. For now, the company hasn't assigned names to these models, referring to them with their generic cooler types. We begin our tour with the "5U dual-tower," a D-type dual fin-stack cooler with two fans in push-pull configuration, and a powerful pair of 140 mm high-RPM fans. There's also the 5U Single Tower, with a single included fan. Then there's the 4U cooler with an 80 mm fan, and a 3U passive heatsink that relies on your rack's airflow. The four coolers on this tray are meant for workstations and server's it's likely that they feature base for server/workstation sockets.

For the client segment, PCCooler brought a pair of top-flow fan-heatsinks, the RC400-53, a 53 mm-tall top-flow cooler with an 80 mm fan; and the larger RC600-67, a 67 mm-tall cooler that relies on a 15 mm-thick 120 mm fan for ventilation. The RT400 is the company's most affordable single tower cooler, it relies on four heat pipes, a fairly slim fin-stack, and a basic FDB-based 120 mm fan. The RZ400 V2 is a step-up, with a slightly thicker heatsink, a more premium FDB fan, a neat-looking top-plate, and cladding on the sides of the fan. For some reason, the design language of PCCooler reminds us a lot about DeepCool.The RT620 is the company's "value" dual fin-stack cooler. It uses six 6 mm-thick heat pipes, and a pair of the same basic 120 mm FDB fans from the RT400. The RZ620 Digital is a step-up, with top-plates that have ARGB LEDs, and slightly thicker fin-stacks. The RZ820X is a dual fin-stack cooler that relies on a concealed central fan to ventilate both fin stacks, and has a large top-plate covering the cooler. You can mount additional fans. This is the most DeepCool-looking product from the lineup. The RZ820 (non-X) comes with an additional 120 mm fan with a custom frame, and a corner with geometric shapes that are illuminated in ARGB.
