1. You don't need any extra fans your case has more than enough and has good airflow (to much fans can break the airflow and actually make the pc run hotter)
2. Why not go for a ryzen r5? It's cheaper, gives the as good as same performance and is aimed more to the future as newer games are needing more than 4 threads.
3. You don't need a liquid cooler it fails faster and is just more expensive just get a decent air cooler and save yourself some money
4. With all those savings you can get yourself a way better gpu and just game better overall.
5. By just getting a cheaper case and not so high end psu you can already get a way better gpu without really dropping the quality of the build.
