Some Deltas are in Round 1. They're beastly...but don't undervolt particularly well (even the tri-blade LE). I must say that Deltas ratings are really consistent with mine...I can calibrate my equipment for any one Delta and every other one gets its exact ratings. NMB-MAT fans get theirs too on the same calibration...really enjoyable to see that YL SL and FN121 and a few others also get their ratings on the same calibration, so it's also good to see a few consumer fans accurately rated (well, consistently...I'm sure SilenX is accurate with w/e calibration they use ).

Yate Loon write up added....didn't say anything I hadn't said before, but it's good to have it all in one place I reckon
