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.. [IMG class=inlineimg]/forum/images/smilies/smile.gif[/IMG]
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.
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.
