It occurred to me that I may be forced to drop off the internet at some point between now and the 24th or so (when I'll probably be returning to London). This is because I don't know the exact situation with the wireless hardware here, in that it presumably belongs to somebody, and if that said somebody is moving out soon (which apparently most are

How many fans do you have drawing hot air [i]out[/i] of the case? Or better still, do you have (or can you get) one of those cases with the tube that drops right down on top of the CPU fan to allow it to draw fresh cool air from outside the case? The one I have is drilled/cut so that you could presumably put a second fan either on top of the case vent or inside between the case vent and the tube, giving you that much more air flow.

There's a slow-ish 120mm fan at the back, as well as the (80mm?) one in the PSU, plus the graphics card has one of those coolers that exhausts out of a second slot.
Intake is less, though; while most of the front of the case lets air in (through a layer of metal mesh and foam filter), in terms of fans there's only a 80mm one, and not really space to add another.

A duct to feed the HS/F with cool air would cool better, I suppose, but I dunno how much of a difference it'd make, considering the air that goes to it at the moment would probably only have passed over the hard drives first? Might still help, but at this stage in Umbra-tan's life I don't think it's really worth a case swap... =P

And if the CPU fan's running at full speed, it cools okay; I just don't like the cost in noise very much. The Scythes, on the other hand, are pretty inaudible even at their (admittedly, a little low) top speeds, so the only thing stopping me deciding straight away to swap fans is that I want to check somehow if they'll shift enough air first.

I'm not real fond of front-case positive-pressure fans. I ran one once, on my very first build, and all it did was pull more dust into the case.

Conventional wisdom says you should always pull hot air out of the device or off of the heatsink, so the more negative-pressure back-case fans you have, the better.

A fair point. Intake fans also tend to be more obvious in their noise, assuming the front is closest to the user.

In my case, though... there's possibly one benefit to that intake fan, namely that it pushes more air over the main hard drives than I think they'd get otherwise. Not sure if that makes much of a difference, but it's probably better to keep them cool than not.
