Several years ago I began using the Yate Loon D12SH-12 pictured below. It has recently come to my attention that the Yate Loon D12SH-12 fan I've been using for heatsink tests is not the same as other fans with the same model number... apparently my version is much more powerful. I've been in contact with Yate Loon, and they've explained that there are no designations between models in the series. The "602" displayed at the bottom of the label simply denotes year and month produced (2006 - February). Can someone help me find the clear acrylic version of the D12SH-12 model?
