actually, this Review is really strange: OCZ Vendetta 2 CPU Cooler Review - Page 10 - Hardware Canucks
All the temperatures measured are way to low - if you compare the results of other pages, you will find out, that e.g. the HDT-S1283 is able to cool a Q6600 under load down to about 58° and not 48,5 as they measured.
Have a look at this german test:
ComputerBase - Scythe Mugen (Seite 4)
(klick on "Vergleichseinordnung in aktuelle Charts
") to see the Results.
One of our high-performance coolers is the Mugen - and as you can see on the computerbase-Review, this cooler without direct touch is a bit better than the HDT-S1283 with direct touch.
