Do you have a power meter (killawatt, power angel, clamp meter)? Can you tell us the AC loads you are seeing?
No I don't have a power meter. I'd assume that my 89W 5600+ x2 chip, 780G chipset, and an 8600GT card wouldn't cause the PSU fan to ramp up. Besides, it never ramped up before when the fans were turning faster.
Another question how warm is it in the room where the PC is?The S12 isn't perfect but assuming the power draw is low and the room temp is low it shouldn't be a nightmare.
~20-22C. Motherboard temperature (not sure where the sensor is) shows ~40C (it was 33C when I had the AMD stock cooler, so I'm thinking the sensor is around the CPU area). Are there people who have had to swap fans on these? I think the PSU also contributes to a "hushing" or whooshing sound, along with a slight repetitive clicking noticeable up close.
intakes: Scythe 92mm Case Fan x2 - DFS922512L 2000RPM which both got put on 5v the first day and have run that way ever since.I got all those fans under $5 a piece and have no complaints about them or the Solo they are in (other than the power/reset button being so cheap).
Why do you need intakes? I never planned on using intakes on mine, and am infact surprised that my temperatures are that low. With the 120mm exhaust, and 120mm PSU fan, after 2 weeks I noticed a thin line of dust building up on the front bezel vent, signifying that the negative air pressure setup is working.
oh and I am using the filter.
I've completely removed the metal CD drive covers, the 5.25 to 3.5" converter, the front fan holder and filter to allow more air to enter from the front. Dust doesn't bother me too much.
