The Swiftech MCW6500-T-775 Thermoelectric CPU Liquid Cooling Block is a thermoelectric CPU water-block designed to be integrated with high-end liquid cooling systems such as Swiftech's H20-220 Apex Ultra.

Thermoelectric cooling can bring a processor's temperature down lower than normal liquid cooling because the block core can get lower than ambient temperature. Many of the record setting scores in the past have been done with the assistance of thermoelectric cooling.

The Peltier Device (or TEC) is powered by your computer's power supply and actually lowers the temperature of the processor via a process called the Peltier-Seebeck effect, or simply the thermoelectric effect. While the unit produces heat on one side (cooled by the liquid cooling systems) it cools the other side below ambient temperatures.

If liquid cooling isn't getting you the performance you need, the MCW6500 will do the trick!

Note: This product is intended for advanced users and requires appropriate insulation measures to prevent the formation of condensation in sensitive areas of the motherboard. Whereas Swiftech provides gaskets, and specific installation instructions for a safe assembly, utilization of this device is at the sole risk of the user.

When do I want a TEC cooled system?

"To reduce the processor operating temperature and prolong its life: for every 10°C drop in processor temperature, it is estimated that the life of the processor is doubled."

"To get decent overclocks with little or no additional voltage on the processor and maintain "comfortable" operating temperatures at full processor load."

Is it safe to use a TEC?

"Yes, but only if appropriate condensation prevention measures are used. This is because the processor temperature at idle will drop well below the freezing point. Condensation can be effectively controlled by following the recommended steps described in our installation guide."

How much will the CPU temperature drop with my Intel Core2 processor?

"It really depends on the kit configuration, type of processor, ambient conditions. However, adding the MCW6500-T to an H20-220 Apex Ultra kit and comparing the system thermal performance to the same kit but with the stock Apogee GT cooler provides valuable information as to how the device might improve the cooling performance as shown in the graph in the product pictures (the last picture)."

"How to read the graph: the Y axis shows the difference in temperature between the ambient air and the "case temperature" i.e. the temperature measured at the junction between the MCW6500-T cold plate and the processor integrated heat spreader. The X axis shows the processor heat load. For example at an arbitrary value of 25°C ambient air and zero CPU heat load (origin of the X axis) the blue curve returns +25-50= -25°C "Case temperature"."

"In this graph, we can see that the MCW6500-T yields lower temperatures than the high-end H20-220 Apex Ultra kit at up to 155 Watts constant heat load depending on the power supply used (voltage). It should be noted that there are few common applications and recent games inducing heat loads of this magnitude for a prolonged period of time."

Is it OK to add one or two watercooled graphics cards in my TEC cooled loop?

"Basically yes. In effect, even if the water temperature goes up because of the added heat load produced by the TEC, all our tests indicate that the temperature of the GPU(s) at full load will still remain considerably below that of stock coolers."

OPPAINTER's Extreme Overclocking Tips:

Peltier cooling likes low voltage. Basically instead of overclocking with voltage, you use cooling from the Pelt. You cannot just go into the bios and crank up the voltage like you would do with a straight liquid cooled system for a max overclock. Start your system at default voltage, and gradually increase the processor speed until you reach your max stable overclock. To get your system stable at the next higher speed, then you can add a smidgen of voltage and repeat your tests. If you increase your voltage too much, particularly with "hot" processors like the X6800 or the QX6700 you risk overshooting the TEC limit and getting worse temps than you would with straight water. However, when you "race" your system for a 3D Marks run with your E6800 or QX6700, you may increase your voltage higher and you'll get better overclocks than straight water for just long enough to make some killer scores! See you in the hall of fame ;)
