Looking for some advice on some quiet case fans for my PC. I believe they are the 120cm variety. Any recent experiences would be valuable, I'm not looking to spend much but I'd like to try and cut the noise down a bit. Has anybody tried using insulation on the case to try and muffle sound? I have some foam which i could use but I'm wondering if that would make the case hotter? The actual case has to live in the cupboard at the moment, not ideal in terms of heat/air circulation but means 'little hands' can't poke around it.
In frustration I once gaffer-taped an old t-shirt folded in several layers to the inside of a case panel. Horrible old case with lots of buzzing, the even horribler mod quietened it down to the max.
Temperature was not a concern at all though, I never measured it.
There are mid priced ($20) 'quiet' case fans around, if your bios does not support variable fan speed in response to cpu/mb temperature (asus bios has cool-and-quiet) then you can get a software solution (speedfan) to do mostly the same thing + alerts if anything exceeds parameters.

If you have a bunch of 2000-3000rpm 120mm fans in there is might be a cheaper option to mod their connection to the psu to use 5v or 7v instead of 12v which will slow down the rpm and reduce noise. http://www.silentpcreview.com/article6-page1.html
Yes, I need to pull the pc apart when I have a chance and check out the fans more closely. Actually while I'm there I'll test to see which one(s) are the nosiest. That's a good point about asus motherboards as I actually have an asus motherboard, an older model but I should check to see about fan control. I think they're just running at a constant speed right now. I might try the foam, I think the main noise is fan noise not so much vibration but I need to have a closer look I think.
Yes I know it's not the happiest place for the PC to be in there but probably safer in there for now. I did think about trying to vent it into the ceiling but it may be more hassle than it's worth.
If it is an older machine, removing accumulated dust and dirt from the fans will quieten it down a bit. The accumulation creates additional vibration and flow resistance. Check the CPU fan as well, smaller fans tend to be responsible for high frequency noise.
