New heatsink idea.
 

This is what i've been playing with in my free time. Whatcha think?

very cool. this was for the quark i assume

Yes, it was specifically designed around the dimensions of the Quark Monster pro controller. Also designed to accept 2 35mm cooling fans. I havent been able to think of a mounting idea though.

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

You would need more airflow to have the same cooling capacity.

I hope you don't mind me posting this here.. I did this a while ago, but don't think I showed anyone other than Mike..

accepts up to 6 40mm fans, and can be bolted directly to the chassis from the 4 corners.

useless IMO?

most likely :024:

A4, having that fan arrangement will be kind of like arranging your solders in a circle around the target on a flat plane. The fans will cancel each other out, unless you run just four fans on the long side with two blowing and two sucking.

well I figured w/ that many mounts, there's multiple options

one fan on each end, one fan sucking, one fan blowing
two fans on each side, two fans sucking, two fans blowing
or just two fans on one side both fans blowing, ect..

*edited to keep neweuser's mind out of the gutter :)

All this sucking and blowing....hmmmm, well, no comment.

:026: :005:

The design is actually pretty good... IMO, I would just run it fanless, it looks like there is plenty of surface area int hose fins. Aluminum though.

Whats in the sink?
 

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.
