Sorry, if I send this more than once: buggy email client.

My computer randomly powers down especially when under load. Replacing the thermal paste and cleaning dust didn't solve the problem. It however not does this bug, when I set "Power Mode" = "Power Saver" setting in Gnome.

I tried to set high = +70°C, crit = +100.0°C, but neither of the following does what I want (it always remains high==crit):

compute temp1 @-30,@0

compute temp1 @0,@-30
