Any used the mCubed Analogue Extension Set - Sensor Hub + flowmeters?

[MrToad]

The main reason I want to use flowmeters is to give me a warning if any of my D5 pumps decide to pack in. One D5 is on a loop with two 8800 GXT so I’d like to know straight away if that pump shuts down.

If flowmeters are flow Killers! would I be better using Temp sensors instead?

Hmmm... the usual problem with the D5... which I don't face because my GTX is in the same loop as the CPU, and I rely (sort of a leap of faith) on the MB built in resources to shut down if the CPU temp goes south.

My next major upgrade (which I've been working on for nearly four months now, thanks to my limited financial resources) involves using the dreaded DDCs, which have rpm sensors, so I haven't looked much into flow meters, as they have very little use to me.

The flow meter I've linked is not that much of a flow killer (like adding an extra MCW60 to your loop if your flow is 1.5 - 2 GPM, you can find the pressure drop curves in the linked .pdf).

However, is £45+VAT, plus the fittings (around £5 for two, unless you can source them "cheapo" somewhere that's not Cole-Parmer, Tom Parker of WSP) and you have to "make your own cable". You'll have to decide how much in terms of restriction and money is your "peace of mind" worth.

EDIT: In other words, the cost of buying and rigging the flow meter, even w/o having to buy the "add-in" for the m-cubed, because you can, in most motherboards, connect the flow meter to the CPU fan header, and set the MB to shut down if the rpm signal drops to 0, is greater than buying a DDC pump w/aftermarket top, that has rpm sensor and therefore renders the flow meter useless for this particular application.
