Is liquid cooling better than fans?
Is liquid cooling better than fans? According to Mark Gallina, liquid cooling more “efficiently distributes heat over more convection surface area (radiator) than pure conduction, allowing for reduced fan speeds (better acoustics) or higher total power.” In other words, it’s more efficient, and often quieter. Is liquid cooling hard to maintain? Liquid cooled systems require […]
