Question 400mm radiator— fans?

[catkicker]

Iooking at a full tower that will house a 400mm radiator
Radiator
Has anyone used this size radiator before? Which 200mm fans did you use

id advise against it...
non standard fan size radiators are horrible.
It took a long time for 140mm to catch up to 120mm because the 140mm fans did not have anywhere near the static curve a 120mm fan had.
200mm fans are worse.
Most of them are designed for noise, and not static pressure.
They were not intended to have something restrictive to fight against, and instead open air class fans.

I would stick with a normal 120mm, or see if you can get 40mm more clearance on the side, and double stack side by side 2 x 360

Had a back an forth with aquatuning, they absolutely recommend.
Noctua 200mm

would be interesting to here from anyone that has used these rads.

Yeah.. lets see how far u will get with that 200mm fan over a 120.

I stand by my recommendation.
Its up to you if you want to consider it or not.
But just alone.... a 120mm fan has over 3x the static pressure that 200mm fan has and is smaller.
You would have a total of 6 for a total of 12 mm H₂O vs 2 for a total of 2.16mm H₂O

That means u going 2 x 360, gives you 6x the static pressure of air vol. though the radiator.

That isn't even if a contest, its a straight up slaughter.

As for the silverstone... they lie.
The numbers never add up.
Noctua does not lie about its numbers, silverstone, always lies.
The values will be taken with someone behind the fan with a leaf blower.

Noctua is my highest recommended company for consumer based fans until you get over to enterprise class.
Then they get slapped silly by companies like Sanyo Denki SanAce, and Nidac.

The most perfect radiator fan is the Nidac Gentle Typhoon, which noctua later on copied.
Noctua:



Nidac Gentle Typhoon:


Oh and i'll even throw in a eK Vador on top.



All copies of Nidac Gentle Typhoon, for it is the BEST fan you can get for static pressure which includes air heatsinks and watercooling radiators.

I’m familiar with those fans, I have
10 EK-Vardar F2-140mm and a couple of 420mm rads. There are people out rhere that have had success with 200mm & 400mm rads.
I was pondering something different
Maybe a bit unique, that’s why I put the question out
To see if any of this forums members have tried these radiators.
I always appreciate input and people sharing there knowledge and opinions.
no matter the delivery.

It's entirely up to you.
I have an old school thermochill pa160.
It was not as great as I hoped it would be.
I even threw in a Silverstone air penitrator fan you listed.
Still was not what I hoped it to be.

I have gotten greedy and tried exotic way too many times only to fail horribly in liquid cooling.

There are reasons why exotics do not become popular.
That 200x2 radiatornis what I call exotic.

Phobya onc3 made a 200x1 radiator, and no one else made them.
Later on phobya discontinued it because it could not even outclass a decent 240,
And would get outperformed by something like a nexxxos ut60 class.
