Fan Config Suggestions For Corsair 4000D

[WarmEngine]

Upgrading my son to the 4000D RGB Airflow.  It comes with the 3-120mm fans shown here (AF120 RGB Elite I believe).  I feel like we need to add at least 1-2 more as 2 intake and 1 exhaust doesn’t seem like enough.  My thought was the 3 intake where they are here then 1-2 for exhaust. Either both at the top or 1 on top and 1 at rear.  Fans are $25/ea.  

 

He’s running a Ryzen 5 5600X with a 6700XT with a MSI Gaming Plus Max B550 motherboard.  Adding an M.2 with his existing SSD and HDD (HDD which will be in the basement with the PSU hence why I like the idea of that bottom fan at the front since it mainly points into the basement.

 

Thoughts on number of fans or any push/pull config setups for those using this case?

Best would be rear exhaust first and foremost, then if he wants to add a top exhaust he can too

Is 3 intake and 1 exhaust enough exhaust or is there too much intake vs exhaust?  That’s why I was thinking 2 might be needed but I’m not well versed on the subject.

If using a CPU air cooler, then just take the lowest front fan and place in the back. Remember more fans = more noise. Also more exhaust than intake = more dust.

Nah its fine, i have 7 intake and 2 exhaust, and thats a bit (read; WAY) too much but its still fine, it just means i have really strong positive pressure, so air flies out wherever it can find and i can run my front fans much slower, so lower noise

Id argue that one feeds a decent bit of air to the GPU and so would be beneficial to keep there

One on the back, one on the back of the top. Or just experiment.

I’ve experimented with the Airflow version of this case (same mesh front as yours, just without the Corsair RGB fans) & 5600X/6700XT combo & found 3 intake & 2 exhausts work best in terms of temps (across the whole motherboard) & noise.

 

Less fans doesn’t necessarily mean less noise, as they may be forced to spin at higher revs to maintain the same temps, so you need to find that balance of fan noise, fan quantity & fan curve.

 

This is the best config I came up with after some testing…

 

You can ignore the top-front intake fan as it’s only there for the extreme warmer times of the year & only turns on when temps get very high, but it’s not needed for most setups.

 

If you have matched, dual CPU fans, then it should be a little better than my single CPU fan setup, but 3 intake in the front, with 2 exhaust on the rear & top-rear should be enough…

Looks reasonable, and I think TeraSeraph proved a similar design last year. However, I think she did back to front flow.
