but surprisingly it seems to be at the performance (in terms of temperature) of the Mugen 5 and Fuma 2.
...yes, in "terms of temperature". But at such high fan rpm, probably any decent 35$ is capable to keep that temperature (for that CPU) -good cooler however, must be silent at that.
And as
@hotaru.hino mentioned (above): used on 65W TDP CPU. As soon you go step upwards (above 100W TDP CPU), you're already limited: 4 heat pipes just can't transfer that much heat as 5 (or more) pipes can -fan rotates at high speed, but heat from CPU is not coming in big enough amount.
About PC noise.. I'm sensible to it and I hate it. Some say, it doesn't really disturb me.. and I wonder
Again, I'm not saying Arctic is bad.. is just an average entry tower cooler. So my opinion stays: if you're ready to pay 45$, then add those 15$... because you will need to listen to it for years
