Sucks And Blows

I installed my two new computers, Kei and Yuri, in Lian-Li 6070 cases, which feature quiet fans and sound insulating foam. I also used Antec super-quiet power supplies.

And then I installed 8 hard drives in Yuri.

Which proved to be something of a problem. I turns out that the reason quiet fans and quiet power supplies are quiet is that the fans are slow. And being slow, they don't move much air. And not moving much air means not cooling the system very well... And 8 hard drives produce a lot of heat.

So I got a nice fast high-volume fan, and I stuck it in Yuri at the back to blow all the hot air out. In fact, I had to duct-tape it to the existing fan, because there is only exhaust vent and the existing fan is attached with these annoying plastic rivets which are impossible to remove. It's far from ideal, but there's a lot more air blowing out the back now, which is a good thing.

But. All the air is coming from the newly-enhanced case fan, and none of it from the power supply fan. And the case above the power supply is starting to get a little warm. A lot warm, really.

After a few moments I realise that the new high speed fan is doing such a good job pulling air out of the case that it is reducing the air pressure to the point where the slow fans in the power supply can't cope. I should be glad that at least it's not sucking air in through the power supply (which would dump lovely pre-heated air directly on top of the CPU).

So I took the side panel off the case. It's running much cooler now, with both fans working together to blow the hot air out. But it's not exactly quiet any more, is it? I said, it's not exactly quiet any more, is it?
