My friend has one of those and it's pretty sweet I intend to get one soon but more for the cooling properties than the noise reduction as five 80mm case fans running at full chat mean that I wouldn’t hear a 747 landing in my street , I do hope it sorts your problem for you mate.
i noticed of all 3 of my case fans, the rear exhaust one is the only one pumping out anything warm...i have a tunnel from the cpu fan out the side panel and that one isn't even warm.
anyways i can't wait till this thing is quiet like its supposed to be, less the noise of the raptor as it reads/writes...but i love that noise for some reason, it reminds me of the noise of scsi drives that i love so much, lol how sad is it when you enjoy the noise of a hard drive haha
Do you mean "nTune"? nTune is for overall system tweaking, whereas RivaTuner is a very powerful video card tweaking tool.
It has a lot of developing as well, because as the name says, it has been in constant updating since the days of the nVidia Riva graphics cards.
