Do you know if these SVC fans are rpm sensing
From the linked fan in SVC:
"Connectors (swappable): included standard 3-pin connector w/RPM signal"

Yes, since they specifically say "w/RPM signal", so this is the BX version, but as Ralf pointed out they are out of stock...

It is really amazing that they manage to sell it at only 50 euro retail price. It looks like a great prize for such a good controller. I would like to hear more about what the PWM frequency does to noise in fans, since this has been a major problem with many PWM based controllers. I think this contr...

If you decide to go with one of the cheaper cooler I suggest either Spire or Arctic Cooling. The main ben...

It would be interesting to see one of these beasts in a SPCR test. The reviews linked so far does not resemble anything that can be repeatable, so no results can be verified.

Heatpipe towers need to get up about 30mm before the lower edge of the fan to clear capacitors near the CPU sockel on socket A. In this case that doesn't even leave room for a 60mm fan, so even if such a cooler existed it would not be a good option. You simply need a bit more height for this kind of...

I don't agree that the Geode would be good for a standalone MP3 player. It is far too powerfull to play mp3 only.

There's a 20V difference between the 2 heatsinks. I'll have to figure out a way to get through that problem without unsoldering the heatsink.

Do you get the problem at startup? My guess is that the huge power draw when starting your harddrives could give you some problem if they all spin up at once. This could cause your 12V line to sag a bit. If this is the problem you should be able to start your computer by flicking the power switch tw...

The small blue PCB mounted upside down on the heatsink looks very much like a fan controller.
