arctic silver would be ok.

real hard core is Coollaboratory Liquid Pro - one wrong drop - GraCa is dead.
but really good results.

>So you are actually using the heat produced by the miner to heat your house?
>Beautiful!
not really, I actually using my heat pump to cool my GraCa Smiley
you can't compare - for the normal flat you need above 20 kWt,
and GraCa s produse only 1 kWt - you barelly notice it.
they just stay at the collant temp, even the pump is heating,
it is only about 44 grad C.

>Nice work there  Smiley
not finished - the coolant stays, if the heat pump pumps,
so backup pump is needed.

>What's the temperature differnece on gpu1 and gpu3?
2-3 grad C
44-46-49

>And are you mining your gpu on stock clock or OC?
noway! I'm mining at 1147-1225
on 7870 3d club
cards set in series, beqause in parallel one always was to hot,
even with 2 waku pums

Also interested in FPGA development.
May be I'll get mu Jalapeno soon, so I need to participate in hw mining disscussion, and custom hw mining.
