Nordic Hardware had the opportunity to test the Corsair Dominator 1866C8 TEC, thi sis the first memory cooling kit that ships with peltier cooling, you can check out the results over here. The reviewer concludes the performance of these memory modules is very good, but says the additional performance from the Peltier cooling isn't that impressive.
Now that we will take a closer look at a new product from Corsair, Dominator 1866C8 TEC, it wasn't the frequency that caught our interest. The word TEC is short for Thermal Electric Cooling, also known as Peltier cooling. In this article we will investigate what kind of effect you can expect from this kind of cooling on RAM.
"Normally you don't even consider the heat coming from the memories. Some have more exclusive heatspreaders than others, some even come with a fan setup, but overall they tend to just work. But when you start packing high-density modules, raise the voltage and start overclocking the effect becomes noticeable. Like with most overclocking lower temperatures are preferred, thus Corsair's Peltier cooling solution."
