I have had some problems with high CPU/GPU temps when playing games, sometimes reaching around he 80C mark which is causing me bluescreens. I am looking to replace my cpu heatsink and possibly my case as I think airflow is a problem. My CPU is a AMD FX(tm)-8350 Eight-Core, my GPU is a NVIDIA GeForce GTX 660 and my mobo is a GA-78LMT-USB3. My case is very small and due to its size my GPU just ends up blowing hot air down onto the bottom of the case and not out anywhere. This is the first time I have really looked into buying parts since I first got the computer in January of 2013 so i'm looking for advice on good cases and a good CPU heatsink as I have no experience on this topic.
