correct me if im wrong but dont the ants already come with fans... why the need to purchase new ones...? also is it recommended to purchase a big one to blow on all of them...? do they over heat quick / often...?
Ants have one push fan, when overclocking them it's recommended to add a a pull fan to keep temperature at an acceptable level.
Or in my case I have them in a very small basement without proper air circulation, without the second fans they are at +50°C, now they are at 46°C
