Hi trepex as usual great info shared here
if you don't mind you could share also your modified ASCII version of asic_test.pl?
I've noticed you did change fans for the internal heatsink and that the new one are positioned lower than the original, did you considered the DPoS way?
which is why I lowered the fans to get 5-7C cooler
anyway did you notice any increase in hashrate due to lower temp?
I will try to get an OK for publishing my (ugly) modified perl script to display the temperature and active cores.
That's the only information I really used for manual tuning at the moment.
I did ask the author (in the KnC forum) if he could publish an ASCII (terminal) version of his tool, never received
an answer there.
My fan had been loose inside that black "cover", the screws you see did nothing! Just decoration!
That had been fine with the original setup, in my setup it would not work. That's why I did use the pure
fans. There is one screw that holds the fan from sliding away from the heatsink. The rubber band (must
find 2 more to have a redundant rubber band installation) does the rest.
I think the asic heatsink is oversized (that's good!) and the cooling for the VRMs is undersized. That's why
I tried to get more airflow on the VRMs and a little bit less on the heatsink.
The additional fans on the side help cooling the heatsink.
Performance:
It looks like my performance did go up (average Gh/s over >12h) from
260-265 (no modding, case closed)
265-269 (case open, 2 fans on the side)
269-272 (case open, 2 fans on the side, 1 fan on top)
272-275 (current setup, 90min average only)
