Noctua NF-A14 FLX Upside Down?

post #1 of 7
Thread Starter 
Is anyone running the NF-A14 upside dow (blowing upwards)? Is does it make any extra noise? I want to make 180mm to 140mm adapters and use three of them in an FT02, but I'm concerned about the orientation as I've noticed that some fans get noisy and/or make rasping sounds when spinning up or down when run upside down like this.

I have an NF A15 (i got it because it was quieter than the one you have)

Other than that, what your stating is strange since the parts they use are to make it extremely quite!

They should not make that much noise, "upside down" is "no such thing" because fans are made to blow in or out you get me? depending on what you need it for!

Have you secured the fans correctly?? (I am guessing you have though)

Rasping should NOT occur with this brand =/ and it would need an RMA (but have you tried fliping it around to see if it still makes rasping noise?)

if you have changed direction & orientation of fans and it still causes the same thing to happen then sadly an RMA may be needed!

I don't have any of them, I'm trying to decide whether to buy them or not.

Like I said: upside down meaning the fan is blowing upwards (mounted horizontally). I don't think I've ever had issues with Noctua fans mounted in this way, but I've had some other fans (scythe, arctic cooling) which were not as quiet when upside down.

Ohhhhhhhhhhhhhhhhh!!
Nah they dont make noise!
Also these fans include the "power reduction cable" which reduces noise levels
Never need to use it since 140mm makes alot let noise than a 120mm.
I have done upward wind and it does not rattle or do anything weird.

I assume its because of the material all being made of rubber, plus no screws, its all rubber attachments so it reduces vibrations by 100% (or at least my ears tell me they do)

I have actually tested the NF-A14 (here). I have also tested NF-P12's, NF-P14's, NF-S12B's, NF-S12A's and NF-A15's. All of them can have their airflow directed upward without problems.

 

The other fans you mention are sleeve bearing fans. Sleeve bearing fans normally cannot direct their airflow upward without problems. The few that can are really good.

Excellent. And I think I'll go with the NF-A15. I'd forgotten about that fan, and I might as well go as big as possible as there's no shortage of space. I just wish Noctua would make a 180mm unit. There are a number of good SS cases that are built around 180mm fans, but thier own fans are shocking, and there aren't really any alternatives.

Welcome to the A15 club bud, great choice! and yes i feel you, wish they made em bigger!
I got mine because of excellent reviews, and this little bad boy is durable, quite, and gets the job done, I remember installing just one brought down case temp by 3C on average.
