Question Phanteks P400 Tempered Glass Airflow

[daltotav]

Hi, I recently bought 4 Corsair AF120mm fans for my case. I placed 2 in the front and 1 in the rear along with 1 in the top rear. Is this a good airflow? I assume it's Neutral Airflow. Onto the next question, while playing AC Odyssey I noticed my GPU temps didn't improve much (i upgraded my 3 old fans to 4 new Corsair ones) and during the game, it stays around 160 to 170 degrees Fahrenheit, what worries me is, is that sometimes it hits into the 174-178 range. I have an old 120mm fan that can be put to use if needed. I can put it at the very bottom of the case where, (which is covered and I will have to remove the slot thing which will expose the Hard Drive, and I will place a 120mm fan in front of it as an intake. If that's possible, will that help? Perhaps I should add it to the top front? Although I did that once and had to remove it because I felt it sucking cold air out and it wasn't necessarily helping at all and temperatures did improve slightly once I did remove it.

Thanks for the help! Sorry if I sound confusing! Pictures will be posted below. Ask me any questions if needed!

Ok

1. Fan positioning and orientation is correct. You got it right. You can leave the psu shroud, it helps channel the lowest fan output to the gpu area.
2. Don't assume you upgraded the fans. All you've done is swap fans. The PH-F120SP fans that come with the case are actually very good fans with equitable cfm to the Corsair's you replaced them with. So it's not really an upgrade, as far as quality of fan goes, you actually went the other way.
3. How are they hooked up and controlled? The p400 has a 3speed fan controller, if you hooked the fans through that, and it's on low speed, you'll get minimal airflow. If going through the motherboard, you can bump the bios settings/motherboard software for better fan control, higher curve so the fans will spin a little faster at a lower temp, better airflow.
4. Part of the issue is that cpu cooler. As cpu temps rise, it dumps more hot air directly into the case, in every direction. A tower style cooler will at least force air towards the rear exhausts.
5. Please use Celcius. Fahrenheit is confusing. Gpu temps under heavy loads like intense graphics can easily push a gpu 70-80°C. Not that uncommon, pretty normal if it's an older gtx or power hungry amd.

Thank you for the quick reply sir!
Concerning your 2nd reply I did keep one of the original fans that came with the PC because it was still running very well and it just needed a little clean up. It is still usable and if so what use can I put it to other than a backup?
Concerning your 3rd reply: The two exhaust fans are hooked directly into the mobo. The 2 intake fans are hooked up with a molex adapter directly to the PSU.
Concerning your 4th reply: I see your logic here and I attempted at least to minimize that issue by placing that top rear exhaust fan you see that's pretty much directly above it. But I may invest into a tower cooler soon.
Thank you!

Also, my graphics card is an MSI Armor RX 580 Overclocked Edition... I have done nothing to further to overclock it than the default 1366 base clock it has, considering it already is overclocked and it serves me well in any game.
