I have a Cooler Master eXtreme 750W PSU in a Gigabyte GZ-X2 Chassis. The PSU is mounted above and there are two fans on the PSU, one facing outside the case and one right below the PSU. At first i thought the fan below was intake fan. But i kept my hand and felt hot air coming out! my CPU's heatsink is directly beneath the PSU. Is this typical, or is there i can do to make the fan an exhaust fan?
