@REALSTYLES - I did not see anywhere you going over TIM. Did you use thermal paste?

No I used just thermal grease and Ideal cob holders and drilled out the holes and used self tapping screws. Did you even read the whole thread it's only 4 pages long and 66 posts after me lol. I used the holders no paste or soldering, plus easy change out when upgrading cob.
Thermal grease, also called thermal paste or thermal compound, is a substance used to promote better heat conduction between two surfaces and is commonly used between a microprocessor and a heatsink .

OK now that we are done playing wordsmith games I have a question... Do you all feel its OK to not use thermal paste/glue/gob/whatever when using these style heat sinks + fans? I ask because the Cree design document calls for a layer of TIM being either paste/gob/glue/whatever.

You should always use a bit of thermal paste. Especially if you're not prepping the mounting surfaces. Arctic silver 5 works great, it's cheap and easy to work with. Just keep in mind, you want as THIN of a layer as possible. So less is more in this instance.

Cree recommends a TIM and vast majority here uses a TIM, what's your point?

From post #1
- Misc: solder, shrink tubing, 18ga wire I use solid wire not twisted for my application, because I'm using cob holders that eliminates having to solder wire to cobs, wing nuts and #8 x 1/2" self tapping screws, thermal grease

aha - i missed that - thanks churchhaze!
and i was not making a point - I was asking a question!

A point of your question. You asked "because the Cree design document calls for a layer of TIM being either paste/gob/glue/whatever." Vast majority of people there uses a TIM, too.
Why would ask whether we feel "OK to not use thermal paste/glue/gob/whatever when using these style heat sinks + fans" when neither Cree nor anyone here suggested so?

Because I overlooked the fact that he mentioned thermal 'grease' and did not immediately relate the two? it was an error on my end. I am not here to try and make myself look smart unlike some of you people - I am here to learn and ask questions.

Is it really necessary to berate someone like this over such a trivial manner? The amount of effort that went into this post, you could have simply answered the question. There is no such thing as a stupid question.

It's hypothetically possible to not use thermal paste, if you could get the surface of the heatsink and cob perfectly level and smooth. This would be the ideal, actually since the tim adds a bit of resistance. However not only is this basically impossible for an individual, but it's also a hell of a lot more work than just squirting a bit of AS5
Supra mentioned he wanted to do a test with a polished cob/heatsink with no TIM. I wonder if he got around to it.

hey Rstyles this is a great way of giving back man thanks in the first place.
i just wanted to ask if you wire up the power cords of the drivers together with the main power cord ?
this is what it looks to me... i was not sure if i could do that.

Yes I did I'm gonna get some wagos and ditch the wire nuts lol.
