    Hello, I'm looking at interfacing a Crydom HS053 heatsink with a 80x80mm fan, but I'm a bit confused by the datasheet. The datasheet of this heatsink says that it accepts 1-80mm fans but there doesn't seem to be any screw holes to attach an 80 mm fan. There are screw holes dimensioned 127x140mm apart but I kinda doubt those are for a fan...

    The only holes on the data sheet look to be for mounting purposes.

    On PC heat sinks the fan screws often gouge into the fins to allow them to be mounted,if that wont work you can always go w/ zip ties.

    Drill couple holes on exterior fins and zip them down just a idea

    Hope it helps

    Will it be a problem that the fan doesn't cover all of the fins? Should I buy a 140mm fan instead of an 80mm fan so that it can cover all the fins?

    It only says up to 80mm fan because that's how high it is.. That heatsink has no provisions for direct fan mounting. The size of the fan doesn't matter nearly as much as the CFM rating.
