I'm building a new HTPC w/ the AOpen i945GTm-VHL mobo + Core Duo CPU (socket 478 HSF connector), and looking for a "completely silent" cooling solution like the one discussed in this article (but compatible w/ 478). Any suggestions?
The Scythe Katana is a nice choice in this scenario, provided it will fit your case. I have one mounted on a T2600 and it can cool it silently up to 2.6 GHz with an ambient room temp of 30C. The fact that itâ€™s installed in a P180 helps here of course.
The Katana is a good fit for Core Duo with a S478 mounting mechanism because its mounting clips donâ€™t need to be inserted under pressure, which would risk damaging the more fragile mobile CPU packaging. Its mounting clips are inserted and then screws are used to hold them in place. It means that the heastink is at the exact right height for the CPU, which isnâ€™t always the case with S478 heatsinks on Core Duo CPUs, due to the difference in height between the two types of CPU packaging.
Itâ€™s fairly light and the stock fan I estimate can cool up to ~45W whilst running silently. Itâ€™s fairly cheap as well, although I recommend it mainly for the mounting mechanism. I donâ€™t think the Mine and Ninja use such a low impact mounting mechanism for S478. They also might not make such a good contact as the Katana, so could even offer worse cooling performance.
