not sure if this helps, but I saw a very neat thread (ba bam!) on homeshopmachinist a while back about making your own half nuts. I can’t remember the exact process, but the gist of it was to use some delrin tube cut in half length ways so it fitted within the metal shell (?), then clamped around the lead screw (or equivalent rod with same pitch and diameter) which was then heated with a blow torch while clamping down on the delrin. By the looks of it, the delrin softened enough to form into the threads. It’s a bit hazy I’m afraid, which isn’t helped by the fact that my lathe doesn’t have a lead screw (or half nuts!) so it’s a somewhat magical dreamed about lathe part that I don’t understand.
if I put solder in the hole of the sinkpad will it be better than heat conductive paste??
does the 2 degrees higher temp make the sinkpads a lot worse?
You won’t notice any difference in real world application georgek.
It’s theoretical maximum temperature at some spot that has 2°C difference in the theoretical model.
Sure flat is better but it’s not like going from Aluminum to Copper :bigsmile:
but these noctigons are two for the price of one sinkpad. and with better thermal design, it almost makes me wonder why anyone would purchase a sinkpad again
not saying toss your sinkpad and buy the noctigon, but just makes sense for future purchases
Exactly. Makes more sense for future purchase since they are cheaper and “better”.
However, cost aside, both will function with relatively little difference. I think the analogy of 2.6A vs 3.0A is a flawed comparison. There is a noticeable difference there.
I was trying to say let's not ignore a small difference (2Celsius), mostly thinking on the number itself 2.6 vs 3, not the current itself 2.6A 3A. I was ironic in that post. I actually like to get the best out of everything, like AR coated lens even if I gain only 5% more light transmission, that 5% is not a standard of course, quality of the AR or single and double sided ca make a difference in gains, or even poor uncoated original can make a higher percentage gain.
I also like the fact that the noctigon is easily available, and a good price, but the gold will reduce performance slightly, i’m not sure by how much though but i do hope its negligible, but it is possible the sinkpad may have a slight advantage being all copper, but i still agree that real world performance should be comparable between the two.
the bottom is also gold plated, and the thermal analysis didn’t take into account the gold portion, i assume it will only make a degree or two difference, but so does the divet in the sinkpad
Didn’t notice that. Good eye.
Though if people are worried about that, they can polish the gold plating off much easier than lapping that divot out.
But if I could get two sinkpads for the price of one noctigon, I would be going for the sinkpad.
