KSB06105HB-A G311 DC 5V 0.40A 4-Wire Cooling Fan, Replacement Electronic Cooling Fan for Laptop, Server & Industrial Equipment, High Speed Quiet Radiator Fan with PWM Speed Control

This cooling fan is a perfect direct replacement fan marked KSB06105HB-A G311, rated DC 5V input voltage and 0.40A rated current, specially customized for heat dissipation of laptops, servers and other precision electronic equipment.

Adopting 4-wire PWM speed control circuit, the fan can automatically adjust rotation speed following the temperature signal fed back by the mainboard. It runs at low speed with low noise under low temperature and accelerates to boost air flow when the device heats up, balancing cooling efficiency and quiet use experience.

The internal high-quality bearing structure effectively reduces friction loss during long-term continuous operation, lowering abnormal vibration and running noise. Optimized fan blade design delivers strong air volume to quickly take away heat generated by CPU, power modules and server chips, avoiding equipment slowdown or shutdown caused by overheating.

Standard wiring interface and overall dimension fully fit the installation position of original KSB06105HB-A G311 fan. Users can directly remove the old fan and plug this new cooling fan without cutting wires or modifying the housing, realizing rapid maintenance and replacement.

Widely applicable for notebook internal heat dissipation, mini servers, industrial control hosts and small electronic equipment radiators. Strictly tested for stable current output, no excessive current surge that may damage the mainboard circuit. It is a cost-effective spare cooling accessory for equipment maintenance shops and DIY electronic repair.
