Server CPU cooler for LGA 3647 sockets
The Dynatron B11 is an aluminium heatsink with an embedded heatpipe and an 80 mm PWM fan, designed for Intel LGA 3647 narrow ILM processors in 3U and taller server chassis. It supports CPU thermal design power up to 205 W and fits within a 110 mm height limit.
8025 axial PWM fan with 2 ball bearing
The bundled 80x80x25 mm fan runs on a 12 V four pin connector providing tachometer feedback and PWM control. Speed ranges from 1300 RPM at 20 % duty cycle to 4000 RPM at 100 %, delivering airflow from 12.5 CFM to 50.0 CFM and static pressure from 0.5 mm H2O to 7.8 mm H2O. Acoustic output spans 16 dBA to 42.2 dBA across the same range.
3U form factor constrains expansion
Maximum cooler height of 110 mm restricts use to 3U or larger rackmount enclosures; it will not fit in 1U or 2U systems. The vertical fan mounting and 600 g weight require secure retention on the narrow ILM. Buyers needing lower profile coolers for 1U or 2U servers cannot use this model.

이 상품에 대한 질문
Will the 2 ball bearing fan need replacement in a 3U server running continuously?
The 2 ball bearing fan is rated for continuous operation at up to 4000 RPM with a 12 V supply; bearing wear is the only moving-part maintenance expected over the cooler's service life
What thermal limit appears first when a 205 W CPU runs at full load in a 3U chassis?
The aluminium heatsink with embedded heatpipe is rated for 205 W; sustained loads at that level will hit the cooler's maximum dissipation capacity before any other limit
How loud and hot does the 80 mm PWM fan get at 100 % duty cycle during all-day operation?
At 100 % duty cycle the fan reaches 4000 RPM, 42.2 dBA noise, 4.8 W power draw and 7.8 mm-H2O static pressure while moving 50.0 CFM through the 110 mm tall heatsink
