Re: Industry heatsink+TIM testing@frostytech
 

No spreading in my die.
All are top surface sources and Waterloo based.
Incoherent is looking at bottom die sources.
Preliminarily work does not immediately support but is early days
Monitoring progress with Waterloo
It is hard going.
Direction and extent of work very uncertain.
May be most productive to concentrate on thermal-geometries for which data is/maybe available - Fluxbloc.

It is a mess.
However, not unhappy that slotted IHS is correct for determining pecking order of heatsinks.
Whether the performance of a heatsink is critical in thermal design is another matter

Re: Industry heatsink+TIM testing@frostytech
 

yes, real data is needed to prove the model

"Whether the performance of a heatsink is critical in thermal design is another matter"
not understood, a chicken and egg thing ?
all temps change with the sink resistance

Re: Industry heatsink+TIM testing@frostytech
 

Yes, all temperatues change.
How much is the important question.
Intel and AMD control the gradients below TIM2
