Thanks for the mention TXSteve. 
The one thing in that video that I wouldn't recommend doing more than once, is bending those ends down on the cube case. It got pretty flimsy the second time I did that and it completely broke off the third time!
KnC used some really cheap metal, which is even more aggravating considering what we paid for them, heh.
As TXSteve mentioned, taking the stickers off the VRMs is a good idea, especially if you use the thermal tape, like they did in the video.
GenTarkin, here's my before and after temps with the heatsinks and thermal epoxy/adhesive. http://i.imgur.com/2aE6f7S.jpg This is on a Neptune cube, but they are laid out the same. That hot VRM must be messed up or something, because it always runs really hot compared to all the rest of my cubes.
These also compare the different fans, KnC's supplied fans and the Noctua upgrade:
Copper Heatsinks with thermal tape: http://i.imgur.com/fcX9cp7.jpg
VS
Copper Heatsinks with thermal epoxy: http://i.imgur.com/yNIsXby.jpg
As you can see, the epoxy worked quite a bit better than the 3M thermal tape that came on the heatsinks.
I didn't do a test going from the stock thick thermal pads, to the heatsinks with thermal tape. I was doing this upgrade on the Bonus Neptune, which came with NO thermal pads! By the time I modified that one regular cube (first link), I had already switched to using the epoxy.
Here's my full gallery if you want to browse through the rest: http://imgur.com/a/zQDSa

Hey I had a thought...has anyone been crazy enough to 'water cool' these Titans or Neptunes...that would be cool (and likely expensive) but man that would be
a cool youtube video
(I nominate TXSteve (Titan) and Telsaman..(Neptune)... all those in favor...carries....hop right on that will you my good fellows..thanks )
Gentarkin, great job on the software btw, I am one of your donators you mention current above 40A being an issue can you make your software keep the settings in a "safe" range etc ?
you mention current above 40A being an issue can you make your software keep the settings in a "safe" range etc ?I could but it would be largely pointless. Being a tad above 40A is not as dangerous as running these things at temperatures for which they arent rated to handle 40A. So, I think temps are much more important then going over the 40A by a bit. Hence, I would recommend the max temp of my DCDC threshold code to be set to 80 or 85C.
my titan has all them temps beat ...at least this last summer.....the orig 2 dies on 2 cubes that I have OFF have been so since last winter. So the likely
too hot the way I ran them ..did not seem to (yet) have an effect. Basement setup. lostgonzo.imgur.com Just using fans an airflow thru Basement.
Then again my Titans the orig and even the 2nd one probably (newbie on temp beg of summer) been run way to hot under what you know recommend. Kinda
glad I did not know this over the summer would have been freaking out. I thought 90c and below was OK.
The 2nd unit I got from a guy in Australia was run even harder before I even got it. Winter here is Summer there.
The way I can tell from his cubes from my cubes is from the way the paint is flaking off the top....
...got that faded "sun blasted" look....I'm sure it will bite me in the a*ss soon (short life) but whatever been lucky
whatever this is likely my last season of home mining anything ..this winter... anyway if it can hold together and beat elec price thru that season vs coin its a win imho!
Sigh ..I always thought this crypto mining hobby I got into in 2013 would have been a LOT funner with 4 guys and a co-op kinda arrangement..how i used to run a huge gamer BBS...4x the cash. 4x the equip 4x the size..and.someone always available when one of the sysop's cracked up and made a mad dash to throw the dos server off the roof. (ah good times drunk computer builds)
So I would be up to doing a lot of these mods and stuff..but away from the crypto mod herd ..all by my lonesome....little time...and the cowardice of being alone.
Well probably for the best a co-op of 4 buys in 2013 we would probably have been 'taken' by BFL and I'd have 4 less friends..but this stuff would be a hell of a lot more fun
with some more folk. (I've tried ....in upper midwest USA from what I can fathom ..if you do bitcoin..you are more 'evil' then a door to door Amway salesman)
But doing computer mods in my past was always with someone along the lines of 'are you sure you want to do this''wtf did we do wrong i can't get it back together'...and of course the classic ' well that did not work well at all..... we needed a new (? put device here) anyway I guess...er hand me another beer (we used that a lot)
Its not the KNC junk that bugs me on these projects..its the lack of the cooperative effort of others to get around such..ie locally here with the shared crypto viewpoint......so far out in the crypto sticks I am!
