Ok, here's a very good thread to start...
I think we should talk about how we can simply automate a water cooling rig, so that if something goes wrong, the PC will shut itself down.
Now, we should all be familiar with MBM (Motherboard Monitor), which is mentionned several times everywhere, for the purpose of shutting down a PC if the temp gets too hot.
So here's my suggestion: let's expand the idea to include a FLOW SENSOR!
I'd love to get my hands on something like this little gizmo:

unfortunately, I don't speak German. Going through a translator, it seems that this company sells this toy and suggests hooking it up to the motherboard.
I can't find the darn thing in the USA. Anyone?
I also thought about a level sensor for the tank (for those who use one), but since the system is essentially closed, there doesn't seem to be a point, except maybe to hook it up to a LED "low fluid level" indicator.
We could however, include a couple of in-line thermal probes. (I certainly want to know how well the rig is going to perform!
Any comments?
