Quick fan direction question.

[ProdigyJC]

I have two case fans, top and rear, near the CPU. I'm new to building so I accidentally had them both on exhaust so there's absolutely no intake inside the case. Right now I'm getting CPU heating issues 2 weeks later and I want to rule the fans out first. Should I switch one to intake and/or get more fans to place in the front? Also another quick side question, does overheating ruin the grade of thermal paste? My computer shut down a few times due to heating.

CPU - AMD A10 7860k w/ stock CPU cooling
Fans - NZXT s340 Elite case stock fans

you should move one of the fans to the front as intake.

Alright. Cool. I'll move the top to the front right now. Would it be more optimal/quieter if I got more fans? And since my CPU overheated a few times should I replace the thermal paste too?

How do you know it's overheating? What does AMD Overdrive report your thermal margin to be?

Case fans have more effect on motherboard temperatures. If CPU overheats, you should first check CPU fan and if heatsink is properly installed.

Alright I moved the fan. AMD Overdrive says 65°C - 70°C for the thermal margin. And I'm reaching those temps just typing this. The HSF is spinning so I assume it's working, but I'm going to reseat everything now.

The thermal margin is the amount of headroom available not the temperature.

High thermal margins are good , low thermal margins are bad.

Yours is fine.

As madmatt30 says, you're not overheating. You're still 70c away from overheating.
