My Quark Heatsink

Neweuser, I think you misunderstood. There was talk about using thermal compound until the ideal heatsink and mounting location is found. Arctic Silver does make non-adhesive compound which is thicker, but that too will move around unless solidly mounted.

I think we all agree that thermal adhesive is the way to go for the final product.

[neweuser]

Actually, i understood correctly. i just mentioned the regular(radio shack) should NEVER be used. And yes, you can use the adhesive to mount in the end result! And yes, as i previous stated you would need to zip tie with compound. i agree with all. LOL

New bulkheads and diff gears should be in today! I plan to put them in over the weekend.

Lol, just making sure.

Ok - now a question for the people who are familiar with the thermal pastes - what is out there that can be used as a conductor for the heat - but will not conduct the electrical current. Im redoing a heatsink for the MGM 160 with a fan option ( sorry for the hijack ) which includes removing the stock heatsink. I dont want any funny stuff happening when i put on the new fan/heatsink on. The stuff on the stock heatsink is white in color and kinda caulk like.

That white stuff doesn't isolate. The top of the case of most SMD fetts are isolated allready.

A past normally doesn't isolate (elctrical), that's what the silicone or mylar isolators are for. With normal transistors, the metal part of the housing is normally electrical connected and needs to be isolated from eachoters in some designs.

Are you going to have those heatsinks machined? feel free to make a 2nd one for me.. :p

here are a few comparisons of the different pastes out there

This form of Artic silver is non conductive

I cnc'd one yesterday - i dont like the way it turned out though - i have ordered some different bits for the mill - i will redesign it and when i have one that im happy with - ill see if i can sneak another one out for ya also rene..:dft012:

You da MAN Walter.... :p

[neweuser]

Walter is a great guy! Full of info too! Hope the next one turns out for you. Mike said it takes many pratices with the CNC's. I'm hoping after school, i can get one. It would be nice to have!

To add to what Serum has already posted:

While that Ceramique stuff is non-conductive, I would never rely on any paste compound to electrically isolate devices.The layer you are supposed to apply should be VERY thin and actually non-exisitent in some places. Paste is supposed to be used to fill the very small gaps between the mating surfaces, but the non-gaps (bare metal) will and should touch each other.

To HNC's question: There are a lot of common properties between what makes a good electrical conductor and a good thermal conductor. It's hard to get a material that is good at one thing, but not at the other.

HNC: Do you have any pictures of the CNC'd one you made? I'm just curious. :)

It's called Back to School night for my teenage daughter who just started highschool:019:

Like my name says...I'm an OLD soldier :)

Don't feel bad; my daughter started high school last year. Now I'm old. :012:

Don't feel bad Guys.. At least, we have got eachother.. :p
