It pushes a lot of air and does a WAY better job at cooling my PC than the Arctic F14鈥檚 I had previously installed in my PC鈥 but I am incredibly disappointed at how loud they are compared to what was advertised. I even bought the recommended anti-vibration pads that Noctua makes for these and it helped with vibration鈥 but not sound. If you want great cooling potential, these are amazing, but if you want a quiet PC鈥 go with Be Quiet.
