Radiator Thermal Test Bench Progress

[DavidNJ]

You are one very industrious dude. Fortunately, my wife isn't expecting me to make cabinets! She just doesn't want me to spend money on manometers, temperature probes, rotational speed gauges, etc.

The testing setup could be better with a shroud; that would test the whole radiator and not just the space under the fan blades.. And the ability to vary up to a static load of .4-.6" with 40-50cfm/fan space flow to test the most restrictive radiators. A two-stage or some push-pull setups could get there with aggressive fans. The most aggressive here is rated at 51dba, in a two stage it would pull .7" with over 40cfm. With a shroud and some sound deadening would be in a range Ira would use.

I have an uninstall ed GTX480 here, and can easily imagine it improving right through .6". While I haven't tested it, my lowly MCR220 with single stage shrouded Panaflo 120x38 Ms could easily use more.

Some testing is needed, however I imagine the fans work best on the high flow side of knee in their curve. Then adding stages to get the pressure drop across the radiator to get there. However, without the shroud, a significant portion of the radiator surface may not be fully used.

Sidewinder has the Delta, and I'm sure he would make you a deal.
