Hey all. I have a QPack with the specs in my sig and I wanna quieten this baby down, at this stage on a minumum budget. So I thought i would post here with pictures for anyone who is interested, plus to ask for help!
At this stage I have pulled apart the standard PSU and switched the fan with a Vantech stealth with a variable resistor to change its speed. The 120mm from the PSU is currently running at 5V on the exhaust with a standard AMD CPU fan. The PSU fan is definatlly the loudest part, except for the hard drive when it is seeking.
Hence my plan at this stage is to thermally (and audially) isolate the PSU/graphics card and northbridge, which has a tiny passive heatsink. Both the GPU and Horthbridge currently idle at around 50 degrees (according to Nvidia monitor), but get pretty hot under load. So I will put a small 60mm fan running reasonably slow inside the PSU zone to help the northbridge.
Then a similar setup will be used to cool the hard drives (with space for a second drive), again isolated.
Will be back soon with pictures, any suggestions are very welcome.
