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!
