My i5 8400 has been doing quite bad as of late. It struggles to maintain 60 fps @ 1080p with a rtx 2060. Just wondering if this is a cpu bottle neck on my behalf or if my thermals are bad. With using the stock cooler, i get 70 degree's+ at load, 40 ish at idle. Mind you, I live in Australia, so room temp is quite high in the 30's. I plan to buy a new cooler either today or the next few days. Input would be helpful, thanks.
