Yes it is but it's a grill that blocks. I get it why they used it, but it is not necessary for the directed output they tried to achieve, it can be done with blade shape. From my own experience grills are noisy and add a lot of restriction. They probably took care so it's not a loud grill but it will still block noticeably.

I'm past understanding you people; i just amuse myself now, sorry to put it thus, but.. :)

You're after a short, brightly lived beast like a silverstone AP fan; but worry about noise........ and/or low RPM performance.......... sure thing.
Tell us more.

I run 120x38s in my case, and at 7v they probably move more air than the 140s people rave about all the time, and does so quietly, not to be confused with silent. At 12v though that’s another story. I do find it nearly impossible to believe you can achieve maximum performance silently.
 
That rear integrated grill though :(
Price is nuts for a piece of plastic. You could fill out a case with 140mm fans for that.
Agreed but what I had installed previously inside that case was somewhat loud when allowed to run at full speed, exactly like a jet engine.

I only purchased this latest release of a PWM fan model that runs at lower speeds there fore being sufficiently quiet. As long as you get slight air movement inside this case then everything works perfectly in removing old hot air from inside the case quietly.

All up now have only 4 fans altogether that work, 2 AP183's on the bottom of the case - 1 140mm Fan in front of the HR-22 and 1 Fan - 120mm as the exhaust, above the HR-22.
 
Currently have an FT05 which is a bit small for me, so looking forward to the Alta S1 / Raven prototype which AP183's :D
 
I Think I may have to fill my 140mm holes in my case with these fans, and retire some of my older ones.

Ahem, these are 180mm fan holes you'll be requiring here. IN other words, they both require Gaping Holes bigger than what John Holmes could ever leave behind ;) .

That is why in my RV03 case which was built to use these fans can only have these installed because using anything less, needs a complicated adapter to be installed down there. Which I have not got the time to build.
 
Ahh ok gotcha. Well I’m not hurting for airflow so I’ll be ok I guess.
 
Sorry for digging out this thread, I didn't find another recent one.

I'm currently running a rad-setup with 5xAP181 and want to switch over to the new AP183.
The 181 are great for moving air at low speeds, but some of them tend to "rattle" at low RPM (~500) which is pretty annoying.

Could anyone tell me if this also is the case with the 183? Since they have an improved bearing I figured that they should be quieter.
I still can't find any tests/reviews and would like to know how they perform before buying them. :)

I have two AP182 which also use ball bearings like AP183. Man, those ball bearings drive me crazy.

Extremely loud bearing grinding noise (which is normal for ball bearing) at 800 rpm.

Dunno if AP183's new bearing solves this problem.
 
Sorry for the necro, guys, but I'm looking for folks with experience with these fans:

I'm trying to run 3 AP183s off an Aquatuning Splitty4. Normally, the Splitty would return the PWM data to the fan controller, allowing it to ramp all three up or down - I mean, that's basically all it is: a PWM splitter ...

The Splitty works fine on my 140mm fans, but with the AP183s, the Splitty4 isn't returning usable PWM data, and all three fans just get stuffed to 100%.

When I plug the AP183s DIRECTLY into a fan controller (like my Aqua Computer Quadro), everythign is fine.

Aqua Computer support thinks it has something to do with the way the AP183s are put together, but NOT with higher power demands.

Have any of you run into anything similar when using splitters with these fans?
