most of the higher cost fans come with metal or occasionally plastic mount brackets

full shroud fans (below) are more efficient than a fan alone or partial shroud (above)

when theres 8 of those cushion disks, logic says they are used as washers , placed between the ends of the mount ties (two on each connecting mount tie,four on each side, and on opposite sides of the radiator core)and used to protect the radiator fins to prevent the plastic ties from damaging the radiator fins

In many cases they come with 4 long plastic strips that resemble thin knitting needles the idea is for the pad to have that long thin plastic knitting needle, like support connector, pass thru the pads so they spread the clamp force, the pads are like large washers, the thin plastic strip passes thru the radiator between the radiator fins, and the fan brackets or those washer like pads have a one way clamp that grips the plastic connector in each corner holding it firmly (usually as a pull fan )to the inner radiator surface, (occasionally on the outer surface as a push fan)the excess is trimmed off with nippers, this makes for a fairly sturdy and easily mounted pull or push fan attachment
keep in mind that your alternator out-put should be high enough to allow the fans to operate at full speed any time they are turned on, its common for guys to add electric fans and find the electrical draw makes the fans operate at part speed until the engine rpms increase the alternator power output (YOULL NEED TO USE A MULTI METTER IN MANY CASES TO DIAGNOSE THIS)
