Laptop Cooling Pads, Stands and Fans

External cooling pad or replacement fan: outside help or an inside part

Two different products share this category. A cooling pad or stand sits under the laptop and pushes air toward its underside vents; it lowers temperatures a little, mostly on soft surfaces or when the laptop is lifted for airflow. A replacement fan or blower is an internal part that goes inside the laptop and must match the model, voltage and plug. If your laptop is loud or overheating because of dust or a failing fan, a pad treats the symptom while a fan or cleaning fixes the cause.

Fan count, size range and how a pad is powered

For pads, check the supported laptop size, since a pad listed up to 15.6 inches may not carry a 17-inch machine. More fans are not always better: large slow fans move more air with less noise than small fast ones, and RPM figures are a rough guide. Most pads draw power from a USB port, and some pass a port through. Adjustable height stands also improve typing posture. For internal fans, match voltage, current, the shape of the housing and whether the plug has three or four pins.

Questions about Laptop Cooling Pads, Stands and Fans

Will a cooling pad lower my laptop temperature?

A little, mainly when the laptop sits on a soft surface or has intake vents on the underside. Expect a few degrees, not a transformation. Cleaning dust from the internal fans and heatsink often helps more.

Does a cooling pad need its own power?

Most draw power from a USB port on the laptop. Pads with a pass-through USB port give that port back, while large pads with several fans may draw more current than a weak port can offer.

How do I choose a replacement fan?

Use the laptop's exact model and the fan's part number. Voltage, plug type, three or four pins, and the shape of the housing must all match, and the CPU and graphics fans are usually different parts.
