New heatsink idea.

Nice looking sink, but what I'd like to see is something designed to be mounted on the chassis (in some novel way) to sink the heat away rather than relying on fans to dissipate the heat. Air is a lousy thermal conductor and fans are a PITA.

It definitely looks cool with the circles in there. But also, the circles are the downfall of a good heatsink, no offense.

There will be too much back pressure on the fan, I wouldn't be effective at pushing air throught the channels.

If you want to make your own heatsink, make the fins arranged perpendicular to the center of the fan mount. Or, better yet, make the heatsink taller, and arrange the fins length wise for fanless operation?

Just IMO

Hey everyone-
Thanks for the positive comments and construcive criticism. Just to clear some stuff up for some of you. Those circles and fillets add surface area to dissipate heat and my material is aluminum. I may sink a slice of 110 copper alloy in the backside to draw heat off faster. Also the fans will be drawing air through the channels not blowing onto them,remember we want to draw the heat away not keep it there. I think though that I have to do some further blending in the transitions and around the entryways. A fanless sink would be loveley, BUT you need to have air blowing through it to work effectively IMO. Any ideas for mounting? Maybe a motor clamp that keeps the con right next to the motor? Shorter wires work better. Back to solidworks. I may produce these on a short basis if any of you are intrested.

The best design for a small add-on heatsink is RC-Monster. IMO

I think your confused, lil too much of the canadian herbs methinks.
Sorry buddy

-Yes, I was talking about the RC-Monster 'looking' heatsink, whats your point?

Excuse me? Sounds like you have been listening to Bush too much, me thinks.
