So I was browsing around 2nd hand pc stuff just to see if I could find something, and I found this:
https://tweakers.net/aanbod/1715935/corsair-hydro-h115i-en-high-end-noctua-fans.html
The guy has a good reputation on that website, that's not an issue. He says the loop is 21 months old.
So if I buy this, I get an Corsair H115i, 2 Noctua NF-A14 Industrial fans, and also the 2 original radiator fans, is this worth it for €100? He isn't going lower than €100
