good enough lol

i think it depends on how long you're going to run it for (pinned at 100% usage) 

like, it'll goto 60c or so, then slowly rise up as there's no cooling the heatsink

thats going to be fine, id say maybe 80C load? depends on external airflow as well

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

depends on ambient temps and what kind of airflow you have in your case...or you can just set the fan at a fixed low speed and enjoy silent cooling...

Try it and monitor your temps during a stress test, it will probably be ok.

Should work, provided it isnt at 100% usage all the time.

you need to understand, having 1 fan running at 700rpm vs running 3 fan of the same speed will produce near identical noise level.

 

either go full passive or dont bother.

Honestly as quiet as the Noctua fans are I wouldn't even bother the cooling benefit you'll get will far outweigh the "silence" you'll get but it depends on your situation I suppose.

why not take an NH-D15 and solder another NH-D15 on top of it to cool the bottom one with the top one?
