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.
