wash the fans in water.

dont worry about submerging them.

Thats how i clean the fans out.

Also the radiator. i take a garden hose and use pressurized water to blast all the fur away from the fins and allow the fans and rad to bake out in the sun to dry.

if i need to pick between my dog and dust, my dog will always win.

So i learned a few tricks to make maintence easier.
