I am planning on getting my first PC assembled soon for AAA gaming at 1080p and in searching the net most all people suggest that aftermarket coolers are not required for locked CPUs. However, in my experience most users online tend to be from EU/US with much colder climates. For the next few months the avg. day time temps here will be 35-40 C, can I rely on stock coolers still or should I get an aftermarket cooler?
