The Be Quiet CPU cooler does a great job of keeping the i3-6100 at under 60C under load while spinning at 40%, where it is pretty much silent. The i3-6100 doesn't generate much heat and the stock cooler is completely fine for it. However, I wanted something with better acoustics. At idle, I have this CPU cooler spinning at around 10% and temps are 30C :)

Great little heatsink! Performance is equivalent to the 212 Evo, if not a little bit better. Looks fantastic as well!

The be quiet! CPU cooler is small and super quiet - It runs at 50% most of the time and keeps idle temps at around 25 Celsius. It looks great too and the price is fantastic. Max temp I have measured so far is 62 Celsius under full load on my i3 7100.

A cheap, quiet CPU cooler. Keeps my i5-6500 cool at 45 degrees Celcius under load.

CPU cooler was annoying to install at first. Very good cooling for such a small cheap fan. Yes I said small but looks good too. 5 because of how cheap this fan is

Super quiet and easy to install.

This little cooler is probably the best investment I'll make with all my hardware. It was absolutely silent on the G4560 and Temps were obviously low. However I've since rebuilt with Ryzen 1600 and overclocked to 3.9GHz and it's still less than 60 degree Celsius during heavy stress testing!!
