The fan of ek is too noisy. It's changed to Biku. I bought 240 models of the first generation before, and this time I bought the second generation 360. It's not only quieter, but also cooler than ek. What a surprise!I hope more people know about the brand of Bicol.
Both the mute and heat dissipation effects are taken into consideration. At full speed, there will be loud noise, but it is within the acceptable range.
