NF-A12x25 FLX,NF-A12x25 PWM,NF-A12x25 ULN
Looking at the table above, we can see a massive reduction in temperature across the board. We managed to lower the temperature in idle by another 1-2°C and up to 5-8°C during load which is awesome. In idle, the NH-U9S is about 1 dBA quieter after the undervolt and 3 dBA quieter when under load. On the GPU side, I recorded a 4 dBA decrease under load which is much better than what we were getting before. Noctua's NF-A12x25 PWM fans are doing an amazing job at moving the air out and bringing in fresh air into the case. Considering how little effort it took to undervolt the CPU and GPU, I think that everyone should be undervolting for huge improvements in temperature and noise levels.
"Noctua's NF-A12x25 PWM fans are amazing and a must have for anybody who wants a silent PC. The NF-A12x25 PWM fans retail for $30 and are worth every penny considering the cooling and noise performance they offer. " (Henry Peshkepija, RelaxedTech.com)
