Holland-based component creator Nexus has updated its processor cooling line-up by introducing the XiR-2300 and XiR-3500. These two coolers have similar specs, come with the same fan but are set apart by the material used for their cooling fins - aluminum for the XiR-2300 and copper for the XiR-3500. The overall weight is also different - 382 grams for the XiR-2300 and 736 grams for the XiR-3500 model. Otherwise, both coolers come with a pure copper base, four 6mm heatpipes, Intel 775, AMD AM2, 754, 939/940 support and a 92mm orange LED temperature controlled fan that spins from 1200 to 2500 rpm (24 dBA at max speed). No word on pricing yet though.
