Thermalright is one of the leading manufacturers of heatsinks and cooling solutions. Thermalright products are well known to the overclocking community world wide and its coolers meet with acceptance when low CPU temperatures are required.

They had previously released a series of aluminum coolers to be used with any 80mm, 92mm or 120mm fans. Following the huge success of the XP-90 CPU cooler, Thermalright decided to make another step forward. Their new improved model, the XP-90C, follows the same design as the XP-90 but it is copper based, ensuring a more effective and efficient heat transfer away from the core of your CPU.

- Features / Specifications

The XP-90C can be installed on any AMD 939 socketed motherboard and in any 745 socketed motherboard. There is also an option to use this nice looking cooler with any LGA775 motherboard, but you will have to purchase the LGA775 RM, which is sold separately.

The Thermalright XP-90C weights more than the XP-90 cooler. With no fan mounted, it weights 690g, and according to Thermalright, with a fan it weights approximately 810g.

It uses the "heat pipes" technology to transfer the heat away from the CPU (4 heat pipes). When the liquid that is used in the heat pipes heats up, it rises because of capillary action and passes through the pipes located in the copper fins. When the special liquid is again cool enough, it returns to its original state and moves back down to the copper base, cold enough to help lower the temperature of the base.

As you can see in the pictures above, almost half the metal fins extend out, past the width of the base and overhang onto the RAM modules when the cooler is in place. This provides cooling for your RAM modules, or for the nearby MOSFET chipset, by blowing cool air downwards onto the modules.

To summarise, these are the main features of the Thermalright XP-90C

• All copper design for maximum performance
• Multiple heatpipes for spreading heat around the copper fins
• Fins soldered to copper base to make effective contact
• Compatibility across multiple platforms (socket 478/754/775/939/940)
• Enormous wingspan gives extra cooling to MOSFET or NB chipset
