Using web interface, so hope this doesn't get sent as html! ok, here's a before and after including uptime: uptime: 11:18AM up 19 mins, 1 user, load averages: 0.12, 0.11, 0.08 sysctl hw.sensors: hw.sensors.acpitz0.temp0=55.00 degC (zone temperature) hw.sensors.acpiac0.indicator0=On (power supply) hw.sensors.kate0.temp2=66.00 degC After sysctl hw.setpert=30 uptime: 11:27AM up 29 mins, 1 user, load averages: 0.34, 0.18, 0.11 sysctl hw.sensors: hw.sensors.acpitz0.temp0=53.00 degC (zone temperature) hw.sensors.acpiac0.indicator0=On (power supply) hw.sensors.kate0.temp2=64.00 degC Fan is blowing at highest speed I haven't had temperature problems either, so I might install 4.6 or even 4.5 and see what happens, since this installation only has the bwi driver added. Nothing else added. By comparison (if that can be done), I booted Debian. Kernel is 2.6.26 and running kde 3.5 uptime is 34 minutes load average: 0.03, 0.11, 0.14 core temp is 49C cpu temp is 52C Fan isn't blowing right now. >> >>> >>> I just installed 4.7 on my laptop, but as soon as openbsd boots, the fan >>> comes on and stays on. >>> Temp is shown as 67C with just console log in. >>> I booted linux with kde and the temp was 42C while running kde. >>> I tried disabling acpi, but that didn't help, so enabled it. >>> Here is my dmesg from /var/run: >>> >>> OpenBSD 4.7 (GENERIC) #558: Wed Mar 17 20:46:15 MDT 2010 >>> [email protected]:/usr/src/sys/arch/i386/compile/GENERIC >>> cpu0: Mobile AMD Sempron(tm) Processor 3100+ ("AuthenticAMD" 686-class, >>> 256KB L2 cache) 1.81 GHz >>> cpu0: >>> FPU,V86,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,MMX,FXSR,SSE,SSE2,SSE3 >>> real mem = 468217856 (446MB) >>> avail mem = 444960768 (424MB) >>> mainbus0 at root >>> bios0 at mainbus0: AT/286+ BIOS, date 02/20/06, BIOS32 rev. 0 @ 0xfd5f0, >>> SMBIOS rev. 2.31 @ 0x1befb000 (24 entries) >>> bios0: vendor Acer version "3A32" date 02/20/06 >>> bios0: Acer, inc.
