Hey its been a while since you started this thread. Just wondering if you found any substitute thermal compound that would work for the S2.

Arctic MX4 was fine - im sure there are cheaper/better options.

Did it make a difference in temperature after you applied MX-4 ?

significant drop on all, but then the state of the previous attempt meant i might've been able to use peanut butter and get  better temps, having applied it correctly

What is the name of this miner? Never seen this before.

After cleaning off the old crap with turpentine/white spirits I'd get some non-conductive (should be white not silver) thermal compound from a computer parts store and put a blob of it on each of those copper heat pads and let it spread out when you screw the heatsink back on.

I never bother with anti static wrist bands just touch a copper radiator pipe to discharge yourself.

Thanks for that!

Look closer - i think you will work out who made/sent this shit.

Unfortunately i dont have copper pipes here, PVC only in sunny asia.

I have begged the manufacturer to provide adequate paste (and capacitors) so that i might redo every one of the 30 blades i expect to be as bad if not worse than this, but while i wait for the dead blade to be returned - i thought id get as informed as i can.

i have 2 tiny tubes of generic no-name chinese 'heatsink compounds' which i was thinking of practicing with - but it seems easy enough unless you're;

 a - not trying

or b - trying to fuck it up intentionally


i have 5 x 20ml of Arctic MX-4 on its way(5000miles) which will no doubt turn up before the RMA'd blade(1000miles)

i'll stick up a pic or two when im done.


id be interested to see the state of other manufacturers heatsink/thermal hatchet jobs - but no need to power down to satisfy me, im pretty confident as to what would be uncovered.


@dogie - are you saying that chips with no thermal paste at all are nothing to worry about or to spread it all over everything?

Wow,awesome that they accept BTC,when did that happen  Grin

BTW,please use either denatured alcohol or electrical contact spray,niether leave a residue & clean very well.An old wornout toothbrush is great for light scrubbing  Wink

Its not as important as people think - people's experiences is coming from CPUs where you have 70-200W on a 4cm^2 block. Each of those blades (from an Antminer S2) is trying to cool 100W from ~400cm^2. Its not just the chip areas that conduct heat, the copper power plane beneath the surface also conducts heat.

tldr, contact surface area is so large that you don't particularly care about the micro-surface area efficiency when putting two rough surfaces next to each other.

Seeing as some manufacturers are happy to ship out mining apparatus with insufficient AND poorly applied Thermal Paste/Grease, i am interested to hear what people think should be done...

i will include an example of what i mean and i would appreciate anyones advice on how it should be done wrt brands, amount, thickness & placement etc

i am in no way educated on these matters but even a blind man could see that what is hidden from view is atrocious and costing us money & shortening the lifespan of our already dismal hardware.

Discuss, prove me wrong, educate us all....




Shite...



Shite...



Same Shite.!

Now i appreciate its just one blade 3 times BUT, if it wasnt DOA who would bother taking any of them apart??

I put it to you that every blade has potentially the same or worse treatment just tucked away out of sight..

what do??

i also appreciate they dont have 'much' mining time left in them so is it worth correcting and if so - how, exactly.

just on the chips, all around the chips too?
