Hi the biggest factor that helped me personally, is the bracket I got. This will void the intel warranty, or so some people say.

My cpu no longer goes above 70-72c on the most extreme loads. Idles at 30 to 40c and hits 55 to 65c on load with one core sometimes peaking ay 70-72c for a split second.

You can always try to undervolt your cpu, or lower clock speed if you want to try for better temps. I have my pc running at max performance, nothing undervolted and no custom cooling, just a big pc case and a nice, overpriced aio lol
