Asking this to be sure: So you can set a case fan at 500rpm and a min of say 30c exhaust. And if it rises to 31 the intake will ramp up till it drops back to 30c? I have been wondering if that's the case since every review I read so far didn't go into detail about the auto's behaviour and I really w...

Thanks very much, I can understand it now. Though in theory there is the so called sound masking effect (http://en.wikipedia.org/wiki/Auditory_masking), different sounds have different characters (e.g. different spectrum and tones). Unless it becomes somewhat "white" like noise (flat spectrum), our...

In other words, does the tube have to be in line with the fan to keep all those nice properties ?
It's the number of fans and how they are chained that matters.

I dont know how tight knit your filter is, but if one good slipstream fan cant make enough pressure to pull air in, then ill be damned. The fact is, it can. And making the sandwich is really, and truely pointless if you can just duct to the front of the case. Either you need to invest in a better f...

Thought I should do a little winter update while I'm at it: -The fan stack speed is reduced to 570~630. It simply can't go lower than that as I can't hear any changes, the biggest noise source is the air passing the filter. However it is a smooth whoosh. -The most annoying source of noise now is act...

Don't take this the wrong way, but the fan stack is useless, despite what you may believe..and here's why. Adding honeycomb does cut down on air circulation between fans, but it actually works against you. All that surface area adds what's called "head loss" in the stack. This head loss is a fricti...

Just use a spare 12cm fan as a desk fan. A good choice is the tri-cool which every owner of the P18x would have some lying around. The built in speed changer makes it a great desk fan with only the power supply to worry about. I used a PSU module from an old fax machine. http://img15.imageshack.us/i...

What did you use to undervolt your video card? Radeon BIOS Editor. A less involved method is rivatuner, google for guides and utilities that may assist in finding out the lowest voltage you can get for your card.

The top fan should be moved forward a bit. It looks like half of its output goes straight to the exhaust and is wasted. +ve pressure is good for back venting vid cards since they will act as exhausts. In a -ve pressure case the can can end up fighting the case exhaust fan for air and need to ramp up...

If you want effective filtered intake you need to concentrate on intake fans. More exhaust fan will hurt the filter's effectiveness.

See my build for an example that focus on filtered intakes.

Looks pretty good! Is the triple fan sandwich really necessary though? (It may be, I'm just curious if you have tried just one fan being ducted through towards the 4870X2). You need it if you want to use air filters as the impedance kills almost all air flow without enough pressure. "Also, your fan...
