and a new phone phone cooler

which is a lot lighter and thinner than my old one, and more powerful.
compared to the BING WANG, it has very very thin radiator fins, it's a lot smaller, and the cooling area is small, but it's light and it's 9-12w depending on the setting, and RGB can be turned off. magnets in it are also weaker.

by comparison BING WANG is big, bulky, heavy, has a fuck off heatsink with a large area, but is only 7w and changing the settings only modulates fan speed so it's always 7w, and you can't turn off the RGB.

I did some throttling tests and in a 24c room the new fan on max speed managed to stabilise at around 37c, and old one was on a 40+ trend and I forgot about the test so it stopped.
all in all, it's good.
