I built a home theater PC from scratch a while back. It has an Intel D945GCZLR motherboard with a Pentium D 925, a passively cooled GeForce 6600, and an Avermedia PCI-e Combo TV Tuner, all inside an Evercase ECE1341 case. I went with the best BTX CPU cooler I could find: the Thermaltake CL-P0191. This thing sounds like a lawn mower.
Even with plenty of airflow into the case and plenty of room in every direction on my entertainment system, the cooler is far louder than the 14-28dBA its marketing materials claim. I have already replaced the cooler’s fan once, but the new one was just as loud.
What can I do to quiet this thing down? Would upgrading to a cooler Core 2 Duo or Quad make a difference? What about upgrading to an actively cooled GPU? Even stock ATX coolers are cooler than this thing—can I just use one of those?
