Can I lower CPU fan RPM with these temperatures?

My CPU fan is kind of loud and I was wondering if it's safe to lower the fan RPM in BIOS. This is info I got from the BIOS:

CPU Temp: 40C
Sys Temp: 26C
Fan Speed: 2000 RPM
CPU Vcore Voltage: 1.192V
CPU IO Voltage: 1.048V
DRam: 1.488V
GPU Volt: 0.45V
3.3V: 3.408V
5V: 5.129V
12V: 12.32V

When I ran Prime95 blend test for 1.5 hours, the CPU temp was ~50C.

MemTest86+ worked fine.

If it's safe to lower the fan, is there a target temperature I want to reach? I want to lower the fan as low as possible since noises really bother me.

  1. Yeah, 2000RPM can be noisy. Your temps look great. As for what temps indicate the danger zone, you gotta tell us what's your CPU...
  2. oops how stupid of me :sweat:

    this is my cpu: Intel Celeron G530 2.4Ghz
