The bottom line: this cooler pairs a 60 x 60 x 25 mm PWM fan with an aluminum heatsink and embedded heat pipe to handle up to 205 W in a 2U server chassis, offering focused cooling where chassis height is limited. For anyone running heavy Intel server CPUs in a constrained 2U bay, the B5 delivers straightforward thermal performance without gimmicks.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact 2U form:\u003c\/strong\u003e The 108.0 x 80.0 x 66.0 mm footprint is designed specifically to fit narrow ILM 2U server layouts while keeping clearance for adjacent components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e60 x 60 x 25 mm PWM fan:\u003c\/strong\u003e The PWM control lets the fan scale from quiet low speeds to full 7000 RPM when the CPU demands maximum cooling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmbedded heat pipe:\u003c\/strong\u003e A heat pipe inside the aluminum heatsink improves heat transfer from the CPU contact plate into the fins for more efficient dissipation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh airflow capability:\u003c\/strong\u003e Measured airflow reaches about 40.6 CFM at full duty, which helps remove heat quickly in tightly packed server racks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable bearings and certification:\u003c\/strong\u003e The 2 ball bearing fan construction and RoHS and UL certifications indicate reliable mechanical life and safety conformity for commercial deployments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe Dynatron B5 is aimed at system integrators, rackserver technicians, and IT teams building or servicing 2U server systems that use Intel FCLGA3647 narrow ILM CPUs and need a dependable, compact cooler capable of handling up to 205 W.
