So I made a new build but I didn't change the case, I'm still using my old case and it has no fans at all. I'm just using one 120MM fan and that's all. I'm using stock cooler for Ryzen 5 2600 and the temps goto 90+ degrees while gaming. I tried Ryzen 5 3600 and they were going to 100 degrees so I guess the issue is with my case and the airflow? I'm new into building PCs so I'm not sure, also the position of the case is also not in the open, it's into a spot under my table. Help would be appreciated, what should I do to keep the temps cool and stable? I'm thinking about buying a new case and a after-market cooler, what cooler do you guys suggest for Ryzen 5 3600? Thanks in advance!
