  • Double ball bearings extend fan lifespan
  • 4-wire PWM enables precise speed control

Compact 12V CPU cooler for tight builds

The Vszerda B127515BU is a low-profile air cooler measuring 75 by 75 by 15 millimetres. It runs on 12 volts DC and draws 0.80 amps through a standard four-wire PWM connector. The copper radiator and double ball bearing fan suit small-form-factor systems where vertical clearance is limited.

Four-wire PWM control and 12 volt supply limits

Speed regulation depends on the motherboard providing a genuine PWM signal on the fourth wire; voltage-only headers will not modulate the fan correctly. The 0.80 amp draw must be within the CPU fan header rating, otherwise the header or the cooler could be damaged. No external power adapter is included.

15 millimetre height decides fit

The 15 millimetre z-height is the single dimension that determines whether this cooler clears side panels, memory modules or VRM heatsinks in a given chassis. Buyers who need more thermal mass or a taller fin stack for higher TDP processors should look elsewhere.

Questions about this item

Which version of the B127515BU fits my CPU socket?

The cooler measures 75x75x15mm and uses a 12V .80A 4-wire fan with double ball bearings; check your motherboard’s mounting holes against those dimensions before choosing.

What does the 12V .80A rating mean once the fan is installed?

It draws 0.80A at 12V, so the 4-pin header on most desktop boards can drive it directly without an external power adapter.

What connector standard does the 4-wire fan use and what does it control?

The 4-wire lead follows the standard PWM pin-out, letting the motherboard vary speed automatically while reporting RPM back to the BIOS.
