Rebuilt an i5 Asus Motherboard adding a Corsair 750 PSU, Asus GTX770. CPU SpeedFan Test showing 80+ degrees and shuts down on gaming when it hits 90+. Cores at 35-40 celcius. Put a much more powerful cooler on it - Akasa X4 but no difference. Do I need something more powerful on the CPU cooler? Changed the BIOS to run the fan at max but also no difference.
