For our testing today we are using a Core i7 920 D0 system which we will overclock to 4.1ghz later. Room ambient temperatures were maintained at 24c.
Chassis: Enermax LuxuRay
Processor: Intel Core i7 920 D0

Power Supply: Thermaltake ToughPower 750W
Windows 7 Ultimate Edition 64bit

Firstly let us have a look at the chassis design and airflow, as it comes ‘out of the box’.
We are testing the case as it comes supplied, with the 120mm front intake and 120mm exhaust fan at the rear. While the case can accept up to 5 fans, there are only two supplied.
The airflow from both fans is quite impressive and the ambient temperatures are maintained at an optimal level.
Now we want to overclock the 920 D0 to 4.1ghz to see how this will affect not only CPU temperatures, but ambient flow.
The overclocked results are impressive, with only a slight rise in some of the ambient locations. The motherboard and memory temperatures rise slightly due to the increased heat in this area.
Now we will add two Enermax 120mm fans to the side panel, one in an intake (lower) and one as exhaust (top).
Simply by adding two high quality Enermax fans to the side panel we were able to reduce the temperatures of both the CPU and the graphics card. Sure, the differences aren't massive, but ambient temperatures were also reduced via our diode readings.
