One of my favorite features of my work machine is how silent it is. I mean, silent. Even under pretty heavy loads it is really quiet. This means no overclocking but I know from experience that overclocking only presents modest improvements and frankly, I'd rather just buy slightly faster hardware that I run at spec (or even below) for quieter day to day operation.
The key features I have going are:
- Corsair RM1000i power supply. I love this thing.
- A big heat sink (instead of water cooling).
- Careful use of fans (basically they're completely off until they need to be on).
Maybe it's an age thing but there is something quite beautiful about a silent, but monster, PC.
