It combines a twin-tower fin array, six pure copper heatpipes and dual PWM fans to move a lot of air while keeping noise reasonable, and the 158mm height fits most mid and full towers. For anyone upgrading a midrange or high-end CPU and prioritizing sustained thermal performance, this cooler delivers clear gains over single-tower designs.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwin-tower design:\u003c\/strong\u003e Two symmetrical aluminium fin stacks increase surface area for heat transfer, improving sustained cooling under load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix copper heatpipes:\u003c\/strong\u003e The pure copper sintered heatpipes rapidly conduct heat from the CPU base to the fins, reducing core temperatures during heavy workloads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAGHP 4.0 technology:\u003c\/strong\u003e The 66mm heatpipe design addresses anti-gravity effects so performance remains consistent regardless of cooler orientation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual PWM fans:\u003c\/strong\u003e A 120mm and 140mm fan combination runs up to 1500 RPM to provide high airflow with controllable speed through PWM headers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e158mm height:\u003c\/strong\u003e The cooler fits most mid-tower and full-tower cases while leaving room for tall memory modules and large GPUs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBroad socket compatibility:\u003c\/strong\u003e Mounting hardware supports current Intel and AMD platforms, including AM4, AM5, LGA 1700 and LGA 1851, for easy cross-platform use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Peerless Assassin 140 White is aimed at PC builders who want a high-capacity air cooler that competes with entry-level AIOs without the complexity of liquid.
