Should I consider Noctua fans or not?

Hey

My NZXT Noctis 450 case uses 3x NZXT fn v2 120mm fans in the front and a NZXT 140mm fan in the back that I don't remember the name of. Would it be worth it for me to change to some more high end fans?

Also, can I gain anything by changing the fans on my NZXT Kraken x61?

Regards, Noiz

Are we talking about the same thing ? Understand that I am not talking about a custom loop, talking "open loop". It's not an "industry term", just my own personal moniker for an all-in-one cooler, something pre-assembled at the factory, that can be expanded ... if you want to,

Installation wise, CLCs and OLCs install exactly the same way. Everything is pre-assembled at the factory
CLCs have 0.1 gpm pumps, OLCs have 1.0 + gpm pumps
CLCs have aluminum radiators with low heat transfer, OLCs have copper radiators w/ high heat transfer
OLCs will drop 5C off the very best CLCs and do it half as loud.

The CLCs are limited by the low coolant flow and aluminum radiator. The high speed fans can compensate to an extent but because...

CLCs like the Kraken use a weak pump and aluminum radiator, as such heat transfer is limited. To make up for these deficiencies, they must use high speed fans. If your goal is to reduce fan noise, you will inevitably reduce performance along with it.

Noctua has very good if fugly fans ... at one time they were the best available but there's a new king in place.

Here we see the Phanteks fans beating (3C) the Noctua fans on Noctuas own cooler will spinning 300 rpm slower.

If you were buying the case / cooler new, I would have suggested and alternative to consider that had all 140s, cooled better and quieter. But changing the fans would cost around $100 and while there would be performance / sound improvements, I don't think they are worth $100.

An air cooler will always cool better than an equivalently priced CLC, being 1/4 to 1.12 as loud is just a feee bonis. If ya want more cooling best option, rather than changing fans, would be to swap out the X61 for a Open Loop Cooler.

The CLCs are limited by the low coolant flow and aluminum radiator. The high speed fans can compensate to an extent but because of the hi fpi radiator, the results gained with even higher speed fans presents a case of diminishing returns. Just so much air ya can squeeze between those tight openings.

Noctua's premium PC fans run at 1500 rpm ... obviously performance will decrease if you use those. Noctua also makes industrial fans that do 3,000 rpm and Delta goes even further (7160 rpm)... The 3k rpm fans draw more than 0.5 amps ... The Delta's 7ks draw 4 amps. You have to be careful here as you could easily burn out a MoBo header with these fans.

2350 and 2650 rpm fans provide some middle ground but as said originallyu, I don't see $100 or more investment will make it worth while.
