Here we are going to look at the types of cooling systems for XFX Speedster MERC 319 Radeon RX 6800 XT Core Gaming and Sapphire Radeon RX Vega 56 as well as their sizes and performance. As a rule, fans with larger diameters have an advantage because they can move the same volumes of air while rotating more slowly than smaller fans. It should be noted that liquid cooling systems in addition to fans and aluminum radiators need some kind of pump, which can also be noisy.
