[quote=Gooserider]Just as a counter argument, do you really want to shut down the PC because the pump quit? Isn't the key issue that something is getting to hot? (like a CPU?) If so, why the concern with detecting pump problems? Wouldn't it be sufficient and more appropriate to look for CPU over heating? /QUOTE]
I have the answer of that, NO.
Lets use a P4 for example, is supose to turn off the computer when it gets too hot, before it reach that point the prosesor is going to slow down ( with the posibility of corrupting any program runing).
Did you ever had problems turning off the computer on windows 98, xp, 2000 and the computer will hang because a program stop responding?
Thats why for some people (and myself) is very important to have a "fail safe", it will turn off the computer without depending on the software.
On my computer, I am running 2 mcp-600 pumps from an external 60w power supply, if that power suply goes bad, or a cable gets disconected, or for some reason the pumps stop working, my computer will shuttdown in 1 second.
