Hardware monitor needed

[Laszlo Nagy]

  Hi,

My FreeBSD 6.2 server restarts suddenly once or twice a day. I believe 
it is because the processor is overheated, but I'm not sure. Is there a 
way to check this from software? I would like to install a hardware 
monitor program that can log out processor temperature in every minute. 
The mainboard is ASUS P5LD2, if that matters. Is there a software out 
there that can do this for me?

Of course I could buy a new processor fan (or a water cooling system) 
but I do not want to spend money before I make sure that is the root of 
the problem.

Thanks,

   Laszlo
