Recently build my first computer. The cpu is a FX 4350. The fan is the loudest thing on there. On idle it is at 4k rpm, at max it hit 6k a while ago. How do I get it to be silent? It is keeping the CPU at around 30C. I ordered a liquid cooler but its not coming til friday. Anything I can do til then? The rest is a AsRock motherboard. I do not know a whole lot about PCs so explain simple to me please. Thank you.
