I wrote Azzo, where I got my hs, to see about getting it replaced as I wouldn't have paid that much for something that wasn't what was being represented, and here's their reply:
<Yes, ThermoEngine decide to use a different design for the heatsink. It kind of caught everyone off guard, especially with a few people starting rumors about performance differences on forums before they bothered to test the two. Now after all the tests are in, it seems the two perform the same with a 7k Delta fan and marginal difference with the stock fan. As far as performing as tested, the solid version does that and since the specs are within Thermosonic's original specs, there is not much to be said. Video card, motherboard, sound card and other manufacturers change their designs everyday with much less fan fare. I think this just got out of hand before people had a place to see their were basically no performance differences. We have sold close to 900 solid core ThermoEngines with just a few complaints about performance, and those came after this issue was raised on the forums and before the results of the comparisons came in.
If you have not seen any of the comparisons, check out

If you still have issues, please let us know,
