Double Checking Airflow

[Silverdogz]

Hey All,

 

I recently built a new PC and unfortunately one of my fans arrived DOA. It's even a Noctua unit! Since I'm returning it regardless, I figured I'd double check if I even needed to replace it. Pictured is my current fan setup in my O11 Dynamic Evo. I'm currently using an intake through the rad on top and another intake on the bottom of the case. My exhaust is through the side of the case. Basically, do I even need to replace the dead noctua fan? I've attached a truly amazing photo to try and illustrate my situation.

 

 

This is my first build in 10 years, I have to say it's quite easy now lol. Only issue was AM5 not wanting to recognize all my RAM on the first boot.

 

 

Any help is appreciated.

Its actually very simple. How are the temperatures?  If they are resonable, no you dont need to replace the noctua fan.
I would personally have the bottom fans as intake like you do now, the side fans as intake instead of exhaust and have the radiator exhaust and a rear fan exhaust.
But there is no need to change anything at all unless temperatures are too high.

There is no need to overcomplicate this

I think the temps are fine, I usually idle around 40 to 50C and I've only seen it get to 90C on a Cinebench run. The GPU is a similar story, only it seems to run about 70 to 80C under heavy load. The hardest thing I have is RE4 Remake, and that gives it a good workout. I doubt this fan would help with GPU cooling anyway.

It wouldn't help much with GPU cooling. It will however help remove excess heat in the case, if its enough to see a noticeable improvement, I dont know.  Your temps seem completely fine so I wouldn't worry at all.
Remember, its also about replace the air inside the case as fast as possible, not just bring cool air in.

In that case it would be nice if armoury crate worked properly. I'd like to set it up so the bottom fans and exhaust fans ramp up with GPU temps since the CPU seems to be unbothered no matter what.

Yeah I understand.  Just set the fans to the fastest speed you can without them being audible, that should be plenty good.
I have 2 front fans and 1 exahaust with my 7700x - overclocked RTX 4080 and max cpu temp is 75c ( 7000 series are made to hit 95c thermal limit first, so they run hotter than any other CPU ) and my RTX 4080 have never seen above 65c  Using NH-D15 at constant 30% fanspeed.

Temps are fine, but the air does not flow in one direction, which means airflow is not exactly optimal.

Rad on the side mount as intake is better, because it doesn't pull that much air to begin with, top as exhaust.

Well in any case I think I'll just replace it, since I may as well have the another exhaust fan to cope with my 6 intake fans. It'll probably be another Deepcool unit since so far they've been nothing but perfect.

Armoury Crate is crap for fan management and once you activate it, it's extremely difficult to disable and won't uninstall with Armoury Crate. Get Fan Control by Remy0o.
