Homemade heatsink - Page 2

post #11 of 33
Diamond and Synthetic diamond are the best heat conductors, theres a wikipedia on it sumwhere

here it is

So carbon is even better? Hmmmm, would CZs work, they're cheaper than industrial diamonds.

Also, would a high-carbon alloy be more effective for heatsink fins, too? Been scoping the available metals for the case (going with steel for now, because I dislike the heat aluminum maintains inside a case, making the fans work harder to clear. Why I still use steel).

umm chemistry doesnt work that way. heat transfer is based on electrons and how many free flowing electrons are in orbit. So if there are less then easier transfer. So infact like the best heat transfer would be like hydrogen but what ahppens to hydrogen after being heated FIRE. so they have to use metals cause metals dont catch on fire as easly. So if you would like to try try some scandium metal and see if u get better heat cause according to chemistry that would be the best.

maybe if you find a way to make the whole case connected to the heatsink with heat pipes , that would make it the largest heatsink ever .

I remember the old thread way back to see if diamond powder would be a better thermal compound. Turns out it isn't because the little microscopic piece of diamond form little triangles. This limits the contact points between all the particles, meaning less conductivity..

Making a custom air heatsink would be terribly inefficient. There is a lot more math involved in engineering an air cooler than a waterblock. Air is much worse at conducting heat so an air cooler must work much better to achieve decent cooling power. IMO stick to premade hs's

May burn down the house too...lol

What I have in mind clears the heat quickly. What I don't want to do is use the window air conditioner and route ductwork around the room though. It's effective, but very ghetto looking.

[Looking at my case] Okay...I like the ghetto look......

I'm gunna talk to my buddy Chris that just graduated from UTA with a Mechanical Engineering degree. He's currently in the shop a lot on the Formula (FSAE) team still but he has access to all kinds of metalworking equipment, I'll talk to him about it tomorrow and see what he can come up with.

I know he's taken a few Heat Transfer courses so he'll know what will work best and how much better.

to beat a tuniq or BT...you'd have to have HUNDREDS of fins...and 4 + heatpipes...

It's just not economically feasible...

Where there's a will, there's a way. Nothing would change if everyone kept to the status quo.

Besides, I need a better case for my needs, not another $$$ one size fits all solution.
