What I would be worried about in this case in terms of passive speakers, are the run lenghts. That warehouse is massive, and cable impedance will definitely have and impact on efficency. Maybe a 70V or 100V system is the viable option to go with, if they choose the passive route, like you probably did with the QSC CX-Q 4K8s, and as you mentioned, it's probably cheaper, not to mention the insane wait times on Dante gear nowadays.

I have no idea on how they are planning to zone out the room in terms of PA, but you might be right with less speakers. The Dynacord MXE5 they have shown a glimpse of in the video is capable of routing 24 Dante inputs into 24 Dante outputs. That's plenty. I have no experience with their SONICUE ecosystem, but for sure they have a control surface for routing.

Now I know, why all the Dante stuff is out of stock almost everywhere. Linus have bought 'em all! Also I pray for the LTT guys, because Dante tends to turn unstable, even on a dedicated VLAN if QoS and packet prioritization (traffic shaping) is not set up correctly, due to it being a very heavily UDP based protocol. I remember a nightmare AV install I did back in the day, where most VLANs were really crowded with UDP traffic (for example with IP cameras) and the network just did not have the overhead to run multiple Dante streams in stable manner, even if everything was set up relatively correctly. If you want to be bulletproof, completely air gap the Dante LAN from the rest of the network. It might be a crude solution, but it works for sure. Also, please feel free hit me with constructive ideas or bad/good experiences regarding large scale Dante stuff.

@Bombastinator @For Science! @AndrewB121 Thank you guys! You helped me in solving the problem! Just bought an NF-A14 Black, and it's miles better than the low performance Be Quiet! . Problem solved. Thread closed.

And yeah, that's the result. The NF-A14 has a decent static pressure, as I have read on Notcua's site. Not as good as the NF-F12 tho. I like Notcua, because they have a good documentation, and honest spec sheet.
-
Yep, I heard this theory as well. I think everything lies in the fanblade design. Number of the blades and the spacing between them. Oh and also the blade angle, and motor torque. Some motors spin slower, but have a higher torque, some spin faster, have smaller torque. Even the bearings are have to be different, because of the the blade assembly puts more linear stress on the bearings in case of a higher blade angle, or at more pressure. It's like a balancing act. And you can bulid the best, most silent motor into a fan, but the sound of the air moving through will have a huuge effect on the sound signature of the device.
-
Okay. If the NF-A14 has great static pressure I will pull the trigger. I wil buy one, put it in front of the VGA. Will see if that improves temps.
-
Yeah, that's gonna work. But Noctua doesn't make an NF-F14. Why? What the frick. I would instantly buy that. Are Artic P series fans any good? P14 PWM for example? I heard, that Corsair's ML140 Pro-s a loud? Is this true? Or NF-A14 Chromax? Does that fan have enough static pressure?
-
These are my temps with the front panel off, the PSU (fan) flipped down and the front fans cranked to 900rpm. (when I stopped the front intake fans, the vga wasn't loud, the front fans make most of the noise) (I know, it's not a fancy screenshot. xD)
-
I took the panel off, and the temps dropped by 8-10C. But the fans are still weak. When I put my hand in the case (when the side and front panel is off) , and the "breeze" is barely noticeable. I really have to crank em' to insanity to achieve a slightly better flow. EDIT: I also removed the front dust filter.
-
There's an always-on mode, and I turned it on, and it didn't help sadly.
-
Nope. I flipped the psu, and the PC is still friggin loud. The GPU temps are constant 75C under load, and the GPU fans a trying to compensate by wramping up. At least it was worth a try. The hot air pocket is still present. So what now? New intake fans?
-
Just opened the PC, turning the PSU. Let's see.
-
I will give it a try. My PSU is a 750w EVGA unit, with the eco mode turned on. But when the system is under load, the fan kicks in, and that's when the "pocket" effect starts to appear. So this might a solution.
-
I have swapped the PCI covers to some Cooler Master one, because the vents are much bigger. I will remove them, and check the temps. Wish me luck.
