The idea would be to take an electronic flowmeter and temp sensor and place it in the w/c loop then connect both to some sort of microcontroller which could be connected to the PCs serial port for monitoring. Then just write a simple monitoring app where the user an set the limits could monitor the data on the serial port and shutdown the computer if these are exceeded.
If anyone has any interest in something like this please let me know, especially if they know something about microcontrollers... I could easily write the software part.

If something went wrong with the cooling CPU temps go up at a high rate. Seems you could monitor CPU temp via software and then do the shutdown? I would think it would be easy to do that. You could check for rate of change and initiate the shutdown when it exceeded a limit.
Since that is obvious, I'm thinking you may be looking to 'pre-sense' catastrophic failure, but I'm wondering if monitoring the CPU temp would still not accomplish that? Auto shutdown at 55C for instance ought to catch it so long as there was liquid still in the loop. If the failure was catastrophic due to lost coolant and the WB went dry, I'm not so sure you could pick it up fast enough to beat the bios shutdown?
