Spacer Sleeve for Arctic Freezer Liquid iii Fan

I installed an all-in-one liquid cooler in my Fractal Era 2 case. From the array of available options, I opted for the Arctic Freezer III. The original 25mm fans proved slightly too bulky, prompting a substitution with 15mm Noctua alternatives. To circumvent the need for a screw search, I engineered spacer sleeves, utilizing them in conjunction with the original fasteners.
