Well on to my OTHER project I just got done.
I have revamped ALL my cubes ..this is a complete repaste/3000 rpm fan/copper heatsinks/Maxumark X bracket replacement and cleaning of cubes. This was 10 cubes total for
me so far out of my 14 cubes. The cost was about 60 bucks a cube but well worth it imho for the temp drop on the dc/dc's alone.
here is a link to all the parts and the best prices I could find on such..the last 3 months as I accumulated the stuff needed.

video in Swedish has more detail and more complete. The 2nd video below in English has less detail. Watch both.

little attention given by myself as possible..and as a result they don't sulk and don't try to brick themselves at any possible perceived slight when I make inadvertent eye contact doing laundry or something..they are 'evil' I tell you (tm knc)
(hey we are all a little crazy to mine crypto.....if I want to think that they are the equiv of a bad Steven King novel in a Christine like an evil asic miner processed kinda deal ..well wth)
Well it worked for 22 months...then I had a power plug go real hot to the touch. It looked fine...but would not pull off...melted in a blob inside.....as a result I looked into the cube and this was what I saw below. See my full setup here if anyone is interested.

Ack!
So much Q-tip and alcohol rubs later on the Titan cube board along with a repaste using the the previously mentioned complete revamp of the cube I have had the following conclusions.
1) you probably should at least blow out your cubes before 22 months have gone by.
2) the rubber used on the knc heatsinks degrades to a point it is all covered in a fine oil. Much the same as if you sprayed the cube with WD-40 oil. Left the rubber mounts under
the board. That may not have been wise we will see.
3) after 22 months the thermal paste ...really really needs to be replaced. (clue: have to use a razor blade ..probably overdue)
4) It is a pain to clean with rubbing alcohol bit by bit but not too hard. The big deal imho is the 3000 rpm fan and the improved air flow with the knc kludge heat sink with
rubber mounts gone. Looks like a wind tunnel. The fan is probably the biggest reason this works so well and cool now.
5) Huge upside on all this when done however with the dc/dc heat being much much less
below are my temps before and after in an 82F basement.
Typical Temp before 82F basement.

Typical temps after complete repaste with parts above listing in mind.

Quite the temp drop. Pretty dramatic. This was again in an 82F basement with the miners running.
End result when done below

So anyway the above parts and Maxumark X brackets really open the cube up to be much cooler as you can see from the above. Then again it may have mostly been due to
the dirt now gone. I'm just saying these are my results. So should be fairly easy to just grab the list of parts above and start working on your own dirty cubes.
Anyway just thought folk would be amused on how far I let them go...quite the motivator to fix thou when you wake up to the fact crap is this badly gone and dirty as hell
