Replacement Fan for EVERFLOW COOLSERVER

The Lemincrash BB7515BU is a 12V 0.80A 4-pin cooling fan designed as a direct replacement for the EVERFLOW COOLSERVER BB7515BU B127515BU unit. It targets technicians and owners who need to restore active cooling to a compatible notebook or server chassis. The package contains a single copper radiator CPU heat sink fan ready for installation.

Sustained Operation at Rated Current

Running continuously at 12 volts and 0.80 amperes, the fan maintains steady airflow across the copper radiator without the speed drop-off seen in short-burst tests. The 4-wire interface allows the host system to modulate speed in response to thermal load, keeping acoustic output proportional to cooling demand during extended workloads.

Upgrade Path from Failed or Noisy Original

This part replaces a worn, noisy or failed OEM fan of the same BB7515BU or B127515BU model number. The jump is worth it when the original unit no longer spins freely, exhibits bearing rattle or cannot maintain target temperatures under load. Buyers needing a different voltage, connector pin-count or physical footprint should verify compatibility before ordering.

Questions about this item

How much noise and heat does the 12 V, 0.80 A fan produce when running continuously?

The 4-pin fan operates at 12 V and 0.80 A, drawing power directly from the laptop's fan header to drive the copper radiator heat sink for continuous cooling.

What connector must my laptop already have for the BB7515BU to work?

Your laptop needs a 4-pin PWM fan header that supplies 12 V DC so the BB7515BU can plug in and receive both power and speed control.

Will the 75 mm square, 15 mm thick frame fit alongside my existing heat pipes without blocking other components?

The 75×75×15 mm copper radiator and fan assembly is designed to match the original EVERFLOW COOLSERVER mounting pattern, so it aligns with the same screw holes and clearance as the stock cooler.
