It is aimed squarely at system builders working with Socket FCLGA 3647 Narrow ILM processors who need a reliable blower-style solution for 1U or taller racks. The single biggest reason to consider the B22 is its combination of a \u003cstrong\u003evapor chamber copper base\u003c\/strong\u003e and a 4-pin PWM blower that supports up to 205 watts of heat dissipation, giving predictable thermal performance for Cascade Lake and Skylake family Xeon chips in constrained chassis.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eSocket compatibility:\u003c\/strong\u003e Built specifically for Intel Socket FCLGA 3647 Narrow ILM so installers can expect a direct physical fit for supported Xeon families.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eActive blower fan:\u003c\/strong\u003e The 4-pin PWM blower allows automatic speed control under load, helping maintain target temperatures while avoiding constant maximum RPM noise.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eVapor chamber base:\u003c\/strong\u003e A copper heatsink with a vapor chamber base spreads CPU heat quickly into the fin stack for more efficient dissipation in shallow server bays.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e205 W cooling capacity:\u003c\/strong\u003e Rated to support processors with up to 205 watts of heat dissipation, making it suitable for many Platinum, Gold, Silver and Bronze Xeon parts used in 1U servers and larger systems.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e1U server focus:\u003c\/strong\u003e Low-profile active design is recommended for 1U servers and up, offering a balance between height constraints and cooling performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe B22 is best for IT professionals, system integrators and hobbyists assembling compact rack servers that use Intel Xeon Platinum, Gold, Silver or Bronze processors on the FCLGA 3647 Narrow ILM socket.
