My cpu is an Athlon 64 X2 Dual core 5600+. I installed lm_sensors-2.10.2 on Mandriva Linux 2007.1. When I run sensors I get these temperatures: k8temp-pci-00c3 Adapter: PCI adapter Core0 Temp: +17?C Core1 Temp: +25?C How come temperature of Core0 is so low? Does this mean that Core0 is not used by my kernel (uname -r: 2.6.20.11-tmb-desktop-1mdvsmp )? What programs should I use so that Core0 is also used Are there shell commands by which I can let Core0 and Core1 work to their maximum? Dieter
