Our Take

Best for: Gamers and PC builders wanting a budget-friendly 240mm AIO with ARGB.

The Cooler Master 240L Core delivers solid cooling performance for its class. The Gen S dual-chamber pump improves water flow and pressure, targeting heat spots effectively. The included CryoFuze thermal paste is a nice upgrade, with 14W/mK conductivity. The 120mm ARGB fans are quiet even under load, and the frosted blade design diffuses lighting smoothly. Installation is straightforward with support for LGA 1851/1700 and AM5/AM4. The white finish is clean and matches many builds. Tradeoffs: a 240mm radiator won't handle heavy overclocking on high-end CPUs as well as 360mm options, and the pump block is fairly large, so check RAM clearance. 99, it's an outstanding value for a reliable AIO.

Price Analysis

At $44.99, this cooler is $9.88 below the original $54.87 and far under the 180-day average of $66.32. It's near the all-time low, making this an excellent time to buy.
