I want to add another fan to my HAF-X case. There is only one room for additional fan which is at the top and away from the back panel.
Currently the setup is standard one which is
Intake: Front 200 mm, Side 200 mm
Exhaust: Top left 200 mm, back 140 mm
The only place where I can add another one is at the top right or away from the back panel and near the RAM and drives.
So when I get it, should I use it as intake or exhaust to create the best balance of negative / positive airflow pressure?
The reason why I am thinking about this is because I live in hot environment and yes I do have the AC turned on most of the day but not all of it and I keep my PC turned on for weeks. So there will be a time when the AC will not be turned on and the PC is still running hot. In addition to the fact that recently I lost a HDD probably because of the heat or maybe the device itself might have been faulty but I'd like to make sure that case has as much airflow as possible.
I guess that it would be best to use the new fan as an intake fan. But this is only my guess and it can be right or wrong I really do not know.
Here is a photo of the case to help you imagine the situation.
Waiting for your suggestions!!
Thanks in advance.
