Fan configurations with a heatsink

[BadNight]

I have a deepcool tesseract and using a scythe fuma to cool a 1600x. I also use a 390 nitro and a side panel fan to feed air to it since my hard drive bays are populated and the front only has 1 fan. I overclocked it to 3.75ghz at around 1.35v. 3.8 is unstable even at 1.4v and 3.9 just doesn't work. So it's more or less a bad chip. I get 75c encoding a video with handbrake, around 60 with games. Doing both at the same time gets it to about high 80c. So it could be better.

I currently have 2 fans on the fuma, both attached to the back fin tower since I'm too lazy to cable manage such a tight case and the front tower can't have a fan on the front thanks to the motherboard cable potentially touching the blades.

For the real question, would it be better to keep the fans this way or would it be better to move the fan to the remaining side panel hole and just have one fan attached to the tower? The way I see it, most of the air passing through the fins towers are coming from the gpu which regularly gets to 75c. So would it be better to feed it completely cold air or just hope the open hole is enough pull air from?

I know it's probably easier to just find out myself. But I prefer not to tinker around there if something isn't broken. The fan mounting clips also aren't fun to work with. It's just more convenient to ask someone.

Are you joking you need better airflow but will do nothing to help it. Clean your rats nest up, mount the fans the right way on the cooler, and add higher CFM fans to the case after that if you still need to.
