Are all those available frequencies safe to run without more cooling? I have no option to measure but "beast" gets pretty hot when I try to kiss it goodnight @796 or more (room temp. never exceeds 20C/70F)...
I'd be interested to know that too. I backed my three down to 700 but the heatsink on the non-fan side is still too hot to touch for more than a few seconds. I have a temp gun, what's a safe temp to shoot for?
Stock cooling solutions is good up to ~800 MHZ, after that you get into overheat territory (not to mention parabolic increase in current draw). The buck and ASIC can handle max frequency but I wouldn't run them unless you can measure temperature and its under 80C on the top of the small heatsink (translates to about 90C ASIC core). Anything past that your reducing the lifetime of the ASIC/buck. This will be even worse if you have a bunch of them together (since they are sucking each others hot air).
Is there a possibility for temp. measurement in the asic it self by the bfgminer software so we can see the temp per MLD.
