The first of the bunch is the Delta 80mm 'Focused Flow' fan. Next up we have the YSTech, a fairly standard contender - moderate noise levels, along with moderate cooling. Basically what T.I.T.I. has done was to take the best elements of construction of all the top cooling solutions and put them together in one product. The Dr. Thermal is a large cooler not entirely dissimilar in style to the Thermosonic Thermoengine, but it is considerably larger, and also has a copper base. It differs from most coolers by having a large 70mm fan rather than the more conventional 60mm unit.
Larger fans cool better than smaller ones at considerably lower RPM, resulting in much less noise.
Both are innovative in design and both deliver on their promise of effective air cooling using the high powered Delta 60 mm fan. The world isn't exactly crawling with after-market Socket 423 coolers, though, and there are even fewer high performance Socket 478 ones out so far. Here are a few. The Volcano 6Cu has a copper base hence the Cu designation after the name. Especially the A102 with the 7000RPM fan has stolen my heart today.
