Review on Case fan ID-COOLING XF-12025-SD, black by Jnis Zeile ᠌

I installed it in the Zalman Z3 plus black case in the lower front pocket. Above is a native zalman cooler 120 mm with blue backlight and a constant speed of 1200 rpm. It sounds ridiculous, but I checked how this and that coolers blow by putting my hand under the airflow and was pleasantly surprised that at lower frequencies, the ID-COOLING cooler creates more airflow and is quieter up to high speeds. For 308 I consider an excellent case cooler.
