Looking for some form of fan shroud/spacer
 

I'm getting to much back pressure from my fans being to close to my rads so I need at least something 3/4" thick to space away from the rad for better efficiency. Anyone suggest somehting not to costly that's easy to make/buy lol.

Fan frames. Just punch out the motor/blades on what fan you get get cheapest, and you're good to go.

Yup its what I had to do to mount my rad to my case worked like a charm.

Another quick, albeit rather sloppy-looking solution is to find some thick styrofoam, and just cut out holes as needed. You'll have to leave the styrofoam area larger than the radiator, because thin walls will break easily, and it won't support much more than the weight of the fan, but sometimes you have a sheet lying around that came as product packaging, so the cost is basically nil.

I can't use reg thickness fans though. I have very littl room & might get by with 1/2-3/4" spacer at the most. even that is pushing it some. I only need it for 3 fans on the BIX rads.

princess auto has fans for cheap$2 , gut out motor an use shell as spacer

Sniper or use a 3/4 plywood for spacer

What sort of cutting instruments/tools do you have? Cutting a fan frame in half will give you a pair of 1/2" spacers. Cutting a 38mm fan frame in half gives you two 3/4" spacers. Hold them up against a belt sander to smooth the mounting surface out, and you're good to go.
