turbine or paddlewheel ? (the latter I think)
I and pH used a (larger - GPI) paddlewheel with some success, fouling is a problem though

but understand that a flow meter is useful only for WCing component tests which cannot be done w/o also measuring the pressure drop (witness pH's difficulties)
-> now a new difficulty; while 0.1°C resolution is sufficient for kit testing, is it sufficient for component testing ?
no
if I truncate my input data it yields 'noise' at low flow/power levels

while I see a need/place for sink and WCing kit testing using a CPU as a heat source, I am most unsure that a CPU is also suitable to test components
- I am not saying that components could not be tested by substitution into a system being tested as a kit (noting the difference etc.),
just that component parametric performance curves will necessitate equipment having more resolution (high-end, elsewhere)

In summation, I am suggesting that review sites not having a high-end calibrated test bench avoid parametric testing as they have not the tools
test cooling solutions, components only by substitution
