It stands out for its six pure copper sintered heat pipes and a pure copper base, which combine with dual 120mm PWM fans to deliver efficient heat transfer. For anyone upgrading from a stock cooler or building a compact gaming or workstation PC, the Peerless Assassin 120 offers a clear improvement in sustained cooling while staying reasonably quiet under typical loads.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix heat pipes:\u003c\/strong\u003e Six pure copper sintered heat pipes increase heat transfer from the CPU to the aluminum fins for consistent temperature control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual PWM fans:\u003c\/strong\u003e Two TL-C12 120x120x25mm PWM fans provide adjustable airflow up to 66.17 CFM for a balance of cooling and acoustic performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePure copper base:\u003c\/strong\u003e The pure copper base and full electroplating reflow welding process improve thermal contact and durability at the CPU interface.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAGHP technique:\u003c\/strong\u003e 66mm heat pipes use AGHP technology to reduce inverse gravity effects, helping performance in both vertical and horizontal orientations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBroad socket support:\u003c\/strong\u003e Includes metal fasteners for Intel and AMD platforms, covering modern sockets such as AM4, AM5 and Intel 1700\/1200\/115x ranges for wide compatibility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact footprint:\u003c\/strong\u003e At 125(L) x 135(W) x 157(H)mm the cooler fits many midtower cases and leaves room for most memory modules.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe Peerless Assassin 120 is ideal for PC builders who want a step up from stock or low-end tower coolers without moving to a large dual-tower or all-in-one liquid cooler.
