My Dell XPS is still loud. Next component to replace is the CPU cooler. It seems to make the most noticeable sound now, especially on load - when building the CPU is used up to 100%, gets hot, and its fan starts buzzing like it's going to take-off.
After reading some reviews and checking what is available at NCIX, where I usually buy my computer parts, I decided to get Arctic Cooling Freezer 13 Pro:
It is supposed to be very quiet and work much better than the original cooler.
So, I got it, opened the case of my Dell, and found the next surprise: the CPU socket on this motherboard is very close to the edge, so close that the huge radiator of the Freezer 13 Pro does not fit into the place without removing the power supply. What a disappointment!
Now I have to decide what to do - take a smaller cooler so it fits there, or bite a bullet, and move the whole computer into another, even bigger case.
