Overview
The Thermalright Peerless Assassin 120 SE is celebrated as the budget king of CPU cooling. Six anti-gravity heatpipes and two 120mm PWM fans running at up to 1550 RPM deliver about ~245W of thermal capacity for a street price around $35, letting builders cool high-end CPUs without spending flagship money. It supports current AMD and Intel sockets in a 155mm tower, making it the default value recommendation in nearly every build guide.
