The new Thermalright SI-120 heatsink is a redesigned XP-120 that offers greater motherboard compatibility while still accommodating a 120mm fan of your choice. In fact, Thermalright claims the SI-120 will fit all known Intel P4 and AMD K8 motherboards (at least they haven’t found one yet it didn’t fit). The SI-120 incorporates five heat pipes to transfer heat out of the copper base into a large array of aluminum fins (just like the original XP-120). The universal mount works with both Intel P4 (socket 478) and AMD K8 (socket 754/939/740) platforms. An optional socket LGA-775 retention frame is also promised.
