Yep. Aluminum frame is super soft and easy to cut. I also drilled the holes to mount the sinks a little bigger than the screw diameter but smaller than the washer. It will give you some flexibility if your hole is a little off the mark.
@ReikoX 's got it right. I donāt recommend using TIM grease or paste to mount SolStix, because I donāt believe its necessary if you use the nylon mounting screws supplied with the 'stix. And thatās mainly, because of the distributed diode design and enormous, relative to COB designs, copper tracing and aluminum backing area that does such a better job removing heat from the diodes in the first place that a little inefficiency at the heatsink interface is easily tolerated.
SolSinks are manufactured to close tolerances as to twist and bend, and then machined flat before adding an anodized black or red coating. The anodization is not only cosmetic, it enhances heat dissipation both at the PCB and atmospheric interfaces, and creates an even more efficient surface for direct thermal transfer from the aluminum strip backing.
But if youāre a belt-and-suspenders type you can certainly add a TIM. If you decide to do so, Iād recommend using thermal grease rather than paste, so that the SolStrips can be removed easily at a later date. Apply as with COBs, as thin and even a layer as possible. If you choose to permanently adhere the strips, Iād recommend considering TIM tape, the tests Iāve seen suggest it is just as effective as paste, and far less messy:
Makes a lot of sense.
One thing to note; at least half the people who refer to āthermal pasteā are really talking about āthermal greaseā. That article you linked to is a perfect example. He calls Arctic Silver 5 āthermal pasteā, but it is not a paste (adhesive), it is thermal compound (āgreaseā). http://www.arcticsilver.com/as5.htm
Thatās why I like to use the term "thermal compoundā when being specific or āTIMā when talking about these materials in general.
Youāre right! I called it paste when in fact it was the Artic Silver grease that I used. Thanks for clarifying. I learn something new here every day!
so shouldnāt toothpaste be called tooth compound?
Technically, yes, although I think it depends which āversionā of English you speak. Certainly not ātooth greaseā, however.
Here in Canada, we donāt typically use the word āpasteā to refer to adhesives (āglueā is much more common), but I know our U.K. friends do say āpasteā when talking about glue - so itās all a bitā¦ uncertain. It makes me wonder if it seems weird to people of the U.K. to hear or say ātooth pasteā - which to you folks must literally mean ātooth glueā.
I think this is the crux of the āthermal pasteā conundrum. When I read this combination of words, I force myself to assume they do not mean āthermal adhesiveā, but rather they are simply incorrectly referring to thermal grease/compound as āthermal pasteā. However, sometimes people really do mean āthermal adhesiveā when they say āthermal pasteā so I am probably fucked one way or they other.
Which is why I love the terms āthermal compoundā and āthermal adhesiveā. Thereās just no doubt what they mean, regardless of what version of English one speaks.
(Thereās a joke about Britsā teeth in there somewhere, but I held back the effort to find it.)
I totally agree with you. I was just pulling your leg Iām what they call in the UK a āgeordieā people who are not from Newcastle most the time canāt understand a word we say. We are the UKs ālegal aliensā
Yeh, I got that you were messing around. Often when I sound like I am being very serious, you can assume I am also messing around. I find humour in ridiculous explanations.
I usually call it heatsink paste, old habitsā¦
btw we usually say glue when we mean adhesive and paste is almost always a non setting gunk of some sort like toothpaste, grinding paste etc.
About the only exception i can think of is paper, while itās glue for almost everything else it suddenly becomes paste when itās for sticking paper. Wallpaper paste is a good example.
The English language must be very difficult to masterā¦ itās a good thing i have no compunction to master anything
Well then āpasteā is actually much closer in definition (between UK and Canada) than I first thought.
We Canadians donāt use the word āpasteā much to refer to glue, but like you said, when we do it is typically used with paper. Some (not a lot) people refer to that white glue in school as āpasteā.
Not surprising really, because we also know how to spell colour, neighbour, etc. correctly.
I just realized that (other than my update in my grow diary) nearly every one of my posts on OG today was totally off-topic. I apologize for this. Iām in a very strange mood today.
lol maybe i should apologize too then, more than half of my posts are completely off topic

Do you mean permanently adhere the strips to the heat sinks with the thermal tape alone?
You spelt āWankerā wrong
dickhead. I was taught by the best wasnāt i?
Yes, TIM tape is all you need. Weāve used it alone very successfully in hundreds of SolSheets without fail.
