120mm Fan Testing on an MCR120 Radiator Round 6

[Martinm210]

that they are a little quieter..... wonder if you have your testbed still set up to see if there is actually any differance with them in pull...

I'm not sure, I think to have anything conclusive to that degree, you would have to test thermally. The only way I can test with my current rig for noise is in push. A test in pull will have the radiator obstructing and muffling the noise, so it would be very much apples to oranges. Also with CFM based testing, I'm completely missing air distribution or shroud effects on thermal performance, and that's pretty important with the TFC fans since they have a built in shroud in pull that theoretically "Should" help distribute the air flow more evenly. I tested those fans in pull in my Monsta radiator review, but that didn't account for noise...only thing I could compare was the performance per RPM which is of little use.

I would suggest trying it yourself and see, it's possible things like the actual case air flow may also have an impact.. I'm not really interested in doing any thermal based testing right now...it just takes too much time and I can't really test noise at the same time with all the data logging requirements.


Anyhow, regarding this thread. I think I've got a method for converting the round 8 results into this group. I've just about got everything tested now, so that leaves the window open for cleaning up my summary mess and I'd like to get as many fans in the group as possible.

My next interest will be to explore the myths around shroud use and noise... Not sure I'll have much time over the coming weeks to do testing with the Holidays, but we'll see...not committing to anything but enjoying the fire and drinking some good eggnogg..
