Yeah it was a good detailed review. I learned several things reading through that.looks like they pushed it to around 4A even with the passive heatsink without hitting any thermal limiters although 90C is pretty darn toasty.

I have about three D5varios and half a dozen different DDCs that should make pretty good loading tools with the vario feature. I also have about 50-60 fans sitting in a box doing nothing..

Only problem with the D5's as test subjects it their rather high minimum voltage being around 8 volts and most high speed fans are similarly low volt unfriendly. I'll figure out a good set of test conditions, but I'm not going to be happy until I see the full 5A or a limiter kick in..
