I've read some very good reviews on Thermal Grizzly Kryonaut thermal grease.  I have some on order to try on my used Antminer S5 that I recently purchased.  Curious if anyone had used it yet on their gear and what kind of results you saw on temperature?

There is no need to repair it, that does not need repaired.

1 x S5 = 0.00878 BTC per day (PPS and Antpool)

I had the thermal compound dry out on a KNC Jupiter one time, used Arctic Silver II and temps went back down. One interesting thing about some ASICs is that they perform well at particular temperatures, too cold and they don't hash effeciently, too hot and they stop.  There's a Goldilocks zone for the chips...

my U3 that lasts 3 weeks without resetting, doesn't car if its -10 degrees Celsius or over 40, it will still hash at 62GHs.
Although, my avalon3 likes to be at 51C to hash at 320GHs at 400MHz, get it down to 41C it cant push past 270GHs it could be a chip or 2 not talking correctly or the heatsink may be flexing away from some chips and they overheat an shutdown...

But..

There is claims out there(http://linustechtips.com/main/topic/362974-thermal-grizzly-kryonaut-the-ultimate-thermal-paste-you-can-actually-buy-it-now-d/) that this stuff could drop a CPU down 6 degrees Celsius.

This stuff claims to have Thermal Transmittance/Conductivity of 12.5 W/m-K, everyones favorite Silicon die killing 24 Carrot Diamond thermal compound does 4.5 W/m-K, Gelid Solutions GC-Extreme does 8.5 W/m-K, Shin-Etsu MicroSI X23-7762 Nano Grease does 4.0 W/m-K, There is "phobya Liquid Metal" that looks to be 2x better then Grizzly, but im still trying to find numbers..

iirc, higher number is better, basically how many watts of heat can be pushed per meter squared per Kelvin (temperature to rise 1 degree), or something like that..

I ended up using it on my S5.  Temperatures dropped about 3 to 4 degrees from whatever was being used on it previously.  I had one ASIC that was X'ing out.  It did it once after I applied the new compound but hasn't done it since.

Sorry I don't have more data, its my first miner and I was in a hurry to get it running. Smiley

Yeah, that happens when you talk on the forums, it could take Days for a response, makes it worse when you want it within the hour..

None the less, not bad temperature drop from just a simple item.

All we need to do now is make a phase changing liquid that creates, or moves a Graphene (or even carbon nanotubestm) latices across the gap of the source to sink.. that would kill any competition Cheesy
