Bought three of these for $6 apiece on ebay to push air through my 30 fins per inch water rad. They draw a little over 19W each but my Sunbeam Rheobus Extreme fan controller handles that easily. As you can imagine, these fans produce massive static pressure.
I was really surprised at how far I could throttle these fans down before they stall. Audible but certainly not annoyingly loud. I turn two of them off and throttle the third one way down unless I am stress testing with some linpack-based heater utility. Even video rendering doesn't drive the temps up to need any more fan power than the one throttled- down fan.
These fans have given me lower stress testing temps by 2-3c over the Switech Helix push/pull setup I had been using. Not a huge amount but the main reason I changed the fans was it makes it much easier to blow out the rad with compressed air without fans covering both faces of the radiator. At the same time I also did some other rearranging of water system components in my case to make it easier to get to things.
I see where these Delta fans have gone from $6 to $12 on ebay. Still a bargain. They are a four wire fan but use a 5 pin Dell server fan connector. I had to convert the connector to a three pin plug but with a little solder and heat shrink tubing it was easy to do and I already had the parts to be able to do the conversion .
