ID-Cooling introduced the SE-903-R tower-type CPU cooler with support for AMD socket AM4 processors, such as Ryzen and 7th gen. A-series "Bristol Ridge" APUs. The cooler is a variant of the SE-903, and comes with factory-fitted AM4 mounting clips and a red LED fan, compared to the blue LED the original SE-903 ships with. Its mounting clips easily hook on to the retention frames that come pre-installed on socket AM4 motherboards.

These aside, the SE-903-R is identical to the original. It is designed for thermal loads of up to 130W. It is a conventional tower-type heatsink featuring an aluminium fin stack, to which heat drawn directly from the base is fed by three 6 mm thick copper heat pipes, and ventilated by a 92 mm fan that spins up to 2,000 RPM, pushing 37.44 CFM of air, with a noise output of up to 23.1 dBA. The company didn't reveal pricing, although it shouldn't be too far off from the $20 price tag of the original.
