The Inq had a chat with some thermal guys who shown them prototype designs from the dual-core server chip Montecito.
They told us that they are working on dissipating 150-200W of heat for Montecito, and that to do that in the small space required for server applications requires the use of a TEC (Thermo-Electrical Conductor). TECs have previously been the realm of hardcore overclockers who want to drive their chips to insane levels of performance.
We asked if the TEC was something fancy, or if it was really required to get the required amount of dissipation out of a heatsink for Montecito. We were told in no uncertain terms that it was an absolute necessity
More info and soon also a picture of the heatsink at The Inquirer
Update:Here is the monster that should cool a 200 watt dual core processor!
