Recommended Fan Configuration For My Build?

[VunnySilla]

Hi everyone,
I hope everyone is doing well, I recently upgraded my pc case to a Corsair 4000D Airflow and was wondering the best fan configuration for my build, I have a Noctua NH-U12A CPU cooler with a total of 5 Noctua NF-A12x25 PWM Fans in total (1 on the back with the fan towards the back, 1 on the CPU cooler facing towards the front of the case and 3 on the front of the case facing towards the front) any suggestions would be great and I know there might be the possibility that I have the best fan configuration already, but I'm curious if there're any other configurations I haven't thought of, thanks in advance.

Me :)

Clarify your facing the back/front as that doesn't say if they're intake or exhaust. Though it could be interpreted in one way or the other.

Generally speaking the bottom/front as intake and top/rear as exhaust.

The front as intake the top and back as outtake. This should provide you enough airflow you'll need.

His case don't have bottom fan slots.

Sorry for not being clear, my bad

- The fan on the back is exhaust
- The fan on the right of the CPU Heat sink is exhaust
- The Three fans on the front of the computer case are intake

you where perfectly clear if they looked at your case link. Don't beat yourself up over it.

My bad, I deleted the post because I thought I messed up, thanks for the advice :)

Note you can go unorthodoxed and configure the top fans to be intake. but that be orthodoxed as thats where the water cooler goes for that case visibly and by what i read. so that is going to have to be an outtake. but bottom fans if you have a duel gpu system some of them bottom fans can harm your second gpu's fan as they are blowing against each other.

The case did come with 2 Corsair fans so I could put them on the top as outtake, then get some more Noctua NF-A12x25 fans down the line, I only have one GPU so no worries regarding the duel GPU configuration

keep the top as outtake. so you have 3 intake and 3 outtake. 1back outake 2 top outake. 3 front intake. thats the best air configuration you can get for that case in terms of airflow.

Usually, front and (if applicable) the bottom as intake. and rear and (if applicable) top as exhaust seems standard as a baseline, and often gives good if not best results. As always, experimenting yourself and collecting results will give you the best answer though. Changing just one thing could change things.

Top fan as intake isn't always necessarily unorthodox; I have mine that way at the moment (I don't have the same case as the OP). Reason being the front two intake are obstructed by many hard drives in the way. I tried the top fan both ways and it wasn't much different, but top as intake gave me the slightly lower results, likely as it brought fresh air in directly in front of the CPU. Granted, that was with my old CPU and it had a tower style heatsink, and since I changed my platform, I'm on the stock (not a tower style) right now so it could have changed, but I'm changing back to a tower style cooler very soon anyway.

My side intake is empty, as having a fan there as intake did little to nothing to temperatures, so it was added noise and dust. I perhaps should try it as exhaust though, since I have positive air pressure (I refer this for dust cleaning reasons), and it might help slightly with temperatures (namely GPU temperatures if nothing else).

I have a voltage selector on my case for the fans connected to it (two front and top) and I run them at 7V; 12 V is louder. PSU fan never really turns on or if it does I never hear it.

This thread inspired/reminded me to do some more testing with my own setup once I change my CPU cooling.

That's why I said generally speaking.

Bottom slots or not the general fan profile for cases is bottom/front as intake and top/rear as exhaust. If a case doesn't have top then the rear would still be exhaust. If there are no bottom slots the front would still be intake.

He shouldn't have to clarify anything if you went to the link he provided before posting.
Like seriously, just give him a direct answer for his case like hunter did. Hunter even been given awards for there response unlike you.

No need to be rude towards him. Everyone makes mistakes, even me and you.

Thanks for the suggestion, I will try it out :-)

Thanks for the suggestion, I will take it into consideration :) I hope your future testing goes well

[Illusion of Progress]

Thanks, and yeah, ultimately that is what will find you your own best results is by testing yourself. Else, you can go with something standard like front intake and rear and top exhaust, and unless you're having issues, it will still be fine, even if it isn't the most efficient.

In my case, I just felt facing the top fan exhaust was bad and it and the CPU fan would be fighting for air from the same spot. Combined with most of the front fans being obstructed, I went with top intake.

Oh I'm sorry I was not on Steam 24 hours a day to provide more responses. Looking at a case image doesn't clarify which fans are intake and exhaust. Specs would but I've known people to switch them up trying for better cooling outcomes. Thus I asked for clarification just to double check and not just make assumptions to be on the safe side. But hey, I'll stick to making assumptions or not posting if I can't be available 24/7.

Oh and I was helpful. I said exactly the same as you just did after I asked for clarification

Is no different to what you and others said

Read MORE of a comment not just the start of it before replying and disregarding the rest. Especially when you say the exact same thing as what was provided.

Thanks for the defence. Not like I hadn't answered exactly the way he wanted either. He just failed to bother reading the next sentence.............
