I think you are contradicting me just for the sake of contradicting me.

Yes, it's the 3200 rpm model. Faster models will have similar curve, as they have the same blades, same bearing, and same motor, just geared a bit faster.

And yes, other fans could push 60 CFM. But they all pretty much did it at 10 dBA louder than the Delta does. 10 dBA is a big difference man!

No matter where your rad is, next.to your ear, or next to your house. I find that most will just adjust the fan speed to a noise level acceptable to them.

So if you decide that 60 dBA is accetable for your rad hanging out the window, the Delta will produce 65 CFM while most other fans will produce around 45 CFM.

That's a big difference man!

GT's are the king of silence. And Deltas are the GT's of high speed.

i don't see the point of doing it in the first place , with this rad after 4h of stress i only get 0,5 °C water temp rise with 4x180mm 800 rpm fans ,..... in passive i get maybe 3 at max , no need for huge fans , you need a huge rad , buy a supernova 1260 and put 4x200mm fans on it and you have something silent that will give no perf lost on your super noisy setup


if you want overkill then get the supernova and get some 110/220V industrial fans of around 400mm and you will get more cfm per db then with your idea , and possibly cheaper too.

QFT, delta fans are fun and all, but how can sit next to such setup for longer period of time? it is unbearable.
Large rad, low rpm fans is the way to go.

Who knows?
Maybe OP is deaf.
Maybe his rad will be outside his window.
Maybe he is running a server.
Or maybe he just wants it for occasional benching.

Agreed.
Using 4000rpm fans look good on paper but in practise? No,the sound is beyond obnoixious.

Aren't those Koolance fans in question just a re-brand delta anyway?

Thread Starter 
Woot i didn't expect this thread to go on.

I will make a radbox with soundproofing and put it in the next room.I am not doing it because it is practical.My current system has AP-13 fans and Alphacool rads.

I just want to try something different from the usual.Who knows maybe i'll find it fun.

Except they do not. You are going by one sample, one model, on a single review.

It is pretty widely known that Sanyo Denkis are the kind of high speed fans for watercooling. Back in the early 2000s when higher speed fans were used a lot more, people used Panaflos or Denkis.
