I am building a new PC soon, and as I am in Australia I am worried that during summer my CPU temps will be too hot to game and so on. Just want an opinion on if I would need a aftermarket cooler. Specs are i5 4690 (Non K), Corsair 250D case, two corsair fans on the case for cooling, stock cpu cooler. In my room I keep my windows open but during the summer it can still get to 35-40° C
