In the above curves, we show the heat dissipation performance of the
MCR220-QP with our Delta M class 120mm fan running at 12, 7 and 5 Volt.
For additional reference, we also show: a high-flow/high noise Delta HE
class fan, and a low flow/low noise Papst fan. Estimated (*) noise
levels are also indicated.
We can see in these curves that good gains can be made from
increasing the flow rates.
In a Swiftech system flowing ~1.5 GPM we observe that with the Delta
1212M fans running at 7v, 200 Watts -corresponding to a typical high-end
dual CPU configuration for example, can be dissipated with a mere 10°C
temperature rise of the coolant over ambient air, and that this is
accomplished at a Noise level of ~30 db(A). We can use the next set of
curves below to predict what would happen if we were to add a couple of
high-end graphic cards to the system in SLI mode.

Dual 120mm fan form factor doubles the surface area available for
convection of the heat into the air compared to single 120mm fan
designs. The Quiet Power design yields superior performance compared to
competing products in the same class.
