Airflow feel slow on P500A / Arctic P12/P14.

[Stormcrownn]

All 7 fans on my P500A are Arctic P12/P14.

 

The front three are intake, and the top 3 are exhaust, also rear fan is exhaust.

 

The top three really don't seem to be moving much air, to the point where I feel like I should flip the first fan to be intake, for 4 intake and 3 exhaust. 

 

CPU is a 5900x and Noctua NH-D15, FTW Ultra 3080 below that.

 

I've wired them through the chained cabling to CHA_FAN1 and CHA_FAN2.  Worried I've done something wrong in setting them up.

Have you tried to adjust the fan curves inside BIOS or a fan RPM software?

I dont think having more exhaust then intake is a good thing

 

Maybe remove 2 of the exhaust fans for 3 intake 2 exhaust

 

And flipping your exhaust side fans to be intake isnt gonna do you any good since the air is gonna recirculate back into the case if im not mistaken

It's possible, if curves are correct, that the NH-D15 is just pulling more air than the exhaust fans. I'd guess the front fan pushes more than the middle or rear yeah?

Or it's possible to run the exhaust fans at a lower RPM, with the three intakes running faster. Your solution would be more logical in this case (pun intended?) as you do want positive air pressure inside the case, not negative air pressure.

Honestly didn't really think about it that way, but that is the case yeah. I'd say front+rear is about the same, the top is the only one that's lighter, but that makes sense now that I think about it.

Temps aren't a huge problem, I was mainly concerned I wired something wrong with the PST/Passthrough stuff or fan header ports.

Oh, ok then. Then I'd refer back to my original post on the issue being fan curves here that need some fine tuning.
