Easy way to find out is unplug them, especially the front one, and see if temps change.
I also suggest removing all unused PCIe slot covers for better front to back airflow.
If your motherboard has a good lower graphics card socket, moving your GPU down will likely lower temps too.

I know -- I was reading your posts about intakes on the top -- but my room gathers a lot of dust and with intakes the rig gets flooded with dust every three months. So I gave up on intake fans -- other than the one in the front, and it has a filter. And I live by the sea (a few blocks from it), so you mix dust and salt air and all my plated pieces get stained with time. It would hinder the resale value.

The difference in dust in between a fan blowing air directly into an object is immense compared to negative or positive pressure. It has been a few weeks since I took away the lateral intakes and the case looks clean. I rather deal with a couple degrees than the dust. And the Carbide is full of entrances and the NH-U14S is working good, so smile.gif

I could test the GPU on a lower PCI-e. Will check the mobo specs.

Maybe I'll work some filters, but the Carbide 300R is getting small. I need a bigger case to start modding it.

But, until you can SP120 PWM versions, the whine might be a PWM issue with the system. If you run the Noctuas in voltage control mode, not PWM, is the whine the same or is it reduced?

I tested both (NF-A15 and A14) in the sys fans (4 pin). The whine remains, even louder at 1000rpm. The BIOS was set on 'Normal'. I disabled it and at 1500rpm they whine like hyenas smile.gif Then I turned the back one off and it stopped. I forgot to turn off the front one (kind of gave up on them smile.gif. I'll do later.

Oh, the back one NF-A14 is whining alone. I'll put it in front of the heatsink later to see if it whines -- and rule out the turbulence of being a puller. I will also check in open air.
post #1084 of 1424
No, the NF-A14 is not whining in front of the heatsink alone as a pusher (at high speed). Must be the turbulence as a puller. Maybe later I'll test with the NF-A15 in the back.
post #1085 of 1424
No love... With the NF-A14 in front and the NF-A15 in the back they whine like hell as well. Must be my heatsink or the NH-U14S has a problem with push pull and its 14mm fans.

Could you please use the edit function to add more to your last post instead of making a new post.
Once or twice in a row is fine but 4-5 times is a bit too much.

Sorry, but most of what you are saying is bases on false logic, false data and false assumptions.
A case only flows the lessor of the two; the intake or the exhaust. A case can only flow the amount of air coming into the case out of the case.
Negative case pressure only means air can leak into case through holes other than where intake fans are.
Positive case pressure only mens air can leak out of case though holes other than when exhaust fans are.
The pressure difference is like the differnece between sea level and 150 meters above sea level. Mabye enough for you to feel it in your ears. ;D

Not in my experience. With the fans blowing direct air I would already have dust accumulation in these last few weeks that I took them away.

Fot the thread in general, here is the video with the whine. The stress test only gets the fan to 1250rpm, so it gets even louder at 1500rpm. It already is. Wait untill the end when it throttles down.

Here is a picture of my setup with a NH-D15S. I am using two Noiseblocker NB eLoop B14-PS fans. The fans got highest rated by pcgameshardware.
However: the fans are 29mm thick, so I made some construction with balsa wood to mount the fans.Goes like a bomb!
I also use the same fan for the case (Fractal Design Define R5) at the back.

Well thats one way to do it but as they say in the military If it's stupid but it works, it isn't stupid.
