I bought this desktop 4-core machine during the coolest part of the year and until very recently I could barely hear the CPU fan except for about one second during power-up when the fan spins way up and then quickly slows down.
Now it's hotter than Hades here and I'm very much aware of the fan noise, but I can't tell if the fan is beginning to fail (the noise sounds a bit harsh to me) or something is merely controlling the speed appropriately. The machines BIOS has no settings whatever concerning the fan or temperature warnings, etc. so I have no idea how to find out the CPU temp. The k10temp kernel module loads automatically at boot with no errors, so I just hope something (somewhere) is taking care of this stuff automatically. But I'm only hoping, not knowing. Any ideas how to find out for sure?
