The International Technology Roadmap for Semiconductors [1] predicts high performance processor power density to more than double by the year 2024, while during the same time allowable junction temperature will decrease from 90oC to 70oC, reducing the junction-to-ambient temperature difference to nearly half. This combined challenge to cooling will require the total thermal … [Read more...]

What! All that just for that? The bonkers world of CPU cooling.
My colleague Ed and I were marvelling the other day at the CPU cooling unit from one of our training desktop PCs undergoing a repair. "What, all that just for that!?". The CPU itself was but a small square wafer compared to the behemoth that was the ducted fan and heatsink with integral heatpipes mounted on top of it. Whereas transistor sizes are measured in nanometres cooling … [Read more...]
Ho, Ho, Ho! Facebook moves to Lapland
What do you call someone who doesn't believe in Father Christmas? A rebel without a Claus. Right, that's that out of the way. This week Facebook announced that it plans to build a 3x 300,000 ft^2 data centers in Lulea, Sweden. The Lulea business agency who helped attract Facebook to their city are dutifully excited as should Facebook be as they look set to capitalise on 10 … [Read more...]
All Detailed Thermal IC Package Models are Wrong… Probably
'Rubbish In -> Rubbish Out' is a well accepted fact in the world of simulation. Regardless of the technical capabilities of your thermal simulation tool, the accuracy of prediction will always be tightly coupled to the accuracy of the input data. The most accurate thermal IC package model is a so called 'detailed' model where all the internal construction is represented … [Read more...]
