Hmm.... I don't think that this is *really* interesting, because the site clearly states that a Dual-Fan
PSU is absolutely necessary and that the heatsink has to be directly within the PSU's (hopefully decent) airflow.
The site says that any Thoroughbred core CPU is *NOT* usable with this heatsink.
The heatsink alone is 59,99€ which is IMO actually a decent price, but for the same money you can get an Thermalright SLK-800 with an undervoltet Papst (or Panaflo or something) that will cool your CPU (any
Socket A CPU) good enough AND you can use a passively cooled PSU or - which is cheaper - a PSU with a Papst N/2GL (even @ 9V or 7V) or an undervoltet Panaflo.
All in all such a sollution is much quieter than anything that *needs* a 'good airflow' Dual-Fan PSU (read: a NON-MODIFIED Dual-Fan PSU - e.g. any Enermax).
So if I had the choice (read: money) I'd go for a "ProSilence FANLESS 350Watt PSU" with an SLK 800 + Papst N/2GL (which I actually own, but with Papst N/2GML - still practically inaudible when case is closed at the moment - one 80GB 'Cuda is not yet enclosed and therefore is louder than the CPU Cooler) and MAYBE (only if absolutely necessary) an undervoltet N/2GL @ 5 or 7V as an exhaust fan..... *this* would beat the "Calmera ks07" + Enermax Dual-Fan in both noise(lessness) and cooling.
Anyways... development goes on and this heatsink is just another indication of this
BTW. I read german, so if anything specific is still unclear I'll try to explain.
