Can anyone offer either a suitable replacement heatsink and fan setup or a mod to quiet my Thermaltake Xaser Volcano 11 cooling setup? I thought I could take the noise but it has gotten to the point where it's all I notice. My machine runs at about 49 degrees Celcius when under normal load and I'm comfortable at that temp but I would like it to be quieter and/or cooler. Any help would be greatly appreciated.
