4.0 out of 5 stars Lower ~ 5°C
Reviewed in the United Kingdom on 24 October 2018
Bought there as a second fan for my Noctua NH-U14S. Using as a push-and-pull. It lowered temp around 5°C. Now the system is 36°C idle, which is great! I hope it doesn’t freeze during heavy loads. The fan seems very efficient. I didn’t give 5 stars as the box came all smashed. Fortunately the fan was intact.
