Next week, I am out on a trip to Black Forrest and won't be able to access my machine physically, i.e. adding a fan. It runs - with the heatpipes - totally without fans as you can see: $ sensors vt1211-isa-6000 Adapter: ISA adapter +3.3V: +3.30 V (min = +3.14 V, max = +3.47 V) +2.5V: +2.46 V (min = +2.37 V, max = +2.63 V) VCore: +1.40 V (min = +1.35 V, max = +1.44 V) +5V: +5.05 V (min = +4.51 V, max = +5.51 V) +12V: +12.09 V (min = +10.77 V, max = +13.22 V) +3.3V: +3.28 V (min = +3.13 V, max = +3.46 V) Case Fan: 0 RPM (min = 0 RPM, div = 2) CPU Fan: 0 RPM (min = 0 RPM, div = 2) CPU Temp: +47.5?C (high = +85?C, hyst = +79?C) Int Temp: +62.0?C (high = +65?C, hyst = +60?C) vid: +1.250 V (VRM Version 8.5) While running burnMMX (cpuburn) for about 3-4 hours, the cpu reaches a top of 65 ?C while the internal temp goes up to max. 67-68 ?C.
