what crashman is trying to say is that
A. you do not NEED a thermal monitering unit.
B. if you are overclocking your computer it is highly recomended. software takes its readings from internal sensors, wich are usually inaccurate. so an external one is adivisable. additionally, how do you plan to look at the software readout when you're playing far cry or halo???(wich is when you need the monitor the most!)
C. they can ve had for very cheap, many are under $30. the inexpensive one's will usually be I/O transfer panels with temperature readouts, and these are perfect.
I've got a book of matches,
I've got a can of kerosene,
I've got some bright ideas involving you and me.
