New heatsink idea.

That doesn't matter as much as you think, ALL heatsinks have a back pressure, you want 'some' restriction, as to increase air velocity.

But yes, in that pic, the outlet is too small, plus the fin design is not efficient, will not work very well.

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

I would think a pin design would work the best since there is a LOT of surface area, not restrictive to airflow, multiple sources for air exhaust, and the pins create turbulence in the airflow which helps dissipating properties. Of course, this would be more expensive to make than simple CNC...

What? Quark dimensions? This won't work?

hmmm, I suppose that's all I need, and i guess the hight of the bottom FET's heatspreader (EDIT) is 3mm.

Does anyone know the exact measurements of the surface of the top FETs and to surface of the bottom FETs? If anyone has taken this with a caliper?

Thanks

[zeropointbug]

Two more measurements: width of the power board PCB?

: The top FET heatspreader has a step out of it, anyone know measurements on it?

Sorry to bother anyone, I'll just have to wait until I get my Quark back before I can do it then.

I've always thought a good design would be a tunnel like heat sink with a bunch of fins on the tunnel and a fan or two blowing in the tunnel (and possibly some sucking air out).

The tunnel effect would be very efficient as all air moved by the fans would be forced to go through the tunnel and cool everything. The only obstacle I found was making it...

Mine only does that "glitch" when my 5s is about to dump....it's like the lipo's don't like going down to 3.0 cut off....

hey zeropoint-
If you read through your responses on this thread, you have changed your mind twice. Those fins and fillets as I said before add surface area to better dissipate heat. Cmon buddy,can't know everything about everything. I can quote you if you want.
Native, thanks for the steady imput.

[zeropointbug]

I'm confused, what are you talking about? The fins and fillet part? I havn't changed my mind on anything, maybe you just misunderstood? You can show me the quote, maybe I can clarify what I meant?

Bush?! Aww cmon man, before he goes to bed every night, he prays cheney doesn't have another heart attack. So he doesn't have to be the real president. Becides, bring me some. Those fins add surface area to dissapate more heat. How may I ask does my heatsink look anything like the one sold on monster?
