plans for 80mm adapter

[JimboZ88]

does anybody have plans/pictures of how to make a 80mm to 60mm fan adapter?

I want a Swifteck 60mm heatsink, but want to use my 80mm Sunon. If you have any plans, intructions, links or pictures as to how to make one, could you please post them.

I am VERY cheap:D, and don't want to spend money on somethig i can make.

Thanks,
Jason Zavarella

I had plans to make one, but ended up getting a 80mm heatsink, but here was my idea. Get 4 strips of sheet metal, about half inch wide, and 1 1/2 inches long. Drill hole towards one side. Screw into heatsink. Then place 80mm fan on top, drop pencil lead through 80mm fan holes to mark drill locations, bolt and enjoy.

I plan to build adapters to mount 70mm Y.S. Tech Tip-magnetic driving fans on my 60mm Foxconn heatsinks. Even if a 70 to 60mm adater was commercially available (and I doubt it), I'd want to build my own. My heatsinks use the "threaded between the fins" fan mounting method, and there's probably over 5mm between where the fan screws are now and the ends of the fins. So I wouldn't want to restrict airflow by using an adapter with a boring square bolt pattern. In another situation, I might agree that funneling the air down to a smaller circle would be appropriate, but the TMD fans have basically no dead air spot in the middle, so...

In my case the adapter can be quite thin and still not impede air much (being only 70 to 60mm, and the screws won't be in the way). I want in to be light, since my motherboard will have two of these things hanging off of it-- and the heatsinks only engage one socket lug. :mad: So, I was thinking of using a roughly quarter-inch-thick balsa board. I haven't priced them lately, but such little boards are a regularly stocked art supply at the college store. If they sold PVC in flat sheets, I'd probably go for that instead-- though there's something neat (if unnatural, pun not intended) about using wood in a PC.


Edit to answer Mizzery without posting again: Oh yeah, plexiglass. I'd thought of that, but it's 2 AM so I forgot.

bet you can get plexiglass at a hardware store, not pvc, but still plastic :D
