CButters Tech Performance Fan

4500 RPM USB-A

Just purchased the 4500 RPM USB A fan and it works surprisingly well for keeping the back cool to the touch and the internal temperature down. Just sounds like a small fan, not that noisy. Even though this is a Surface Pro 9, I opted for the USB A so that I have access to both USB C ports for my two portable monitors I use to extend the display. The power brick has a spot for a USB-A plugin, so just connect the fan there which keeps it separate from the Surface’s internal power supply.

Fast delivery and product works as intended. Helpful for rendering 3D image

Cools well - Noise is negligible.
