"It is pretty sad though when end user reviews seem more usefull than bench testing."

a wake-up call ?

Re: Industry heatsink+TIM testing@frostytech
 

Shoot, I'll be happy when I can measure something, anything. I'm not concerned with the geometry of the processor heat, simply because an IHS and the baseplate of a block will (IMO) smooth things out to be near-indistinguishable.

However, there is some anecdotal evidence that a Storm type design, whose cooling is highly localized, may result in a better overclock. Is there any truth to it? Knowing that the baseplate of Storm is ~1 mm thick, and we know the IHS (~1.4mm for Intel (~1.65mm for LGA), ~2.4mm for AMD), is any localization of the cooling effect going to have any impact, or is it all smoothed out in the thickness?

I'm not sure how I would even go about testing that, unless I used various sizes of heat dies.

Re: Industry heatsink+TIM testing@frostytech
 

I do believe that w/o an IHS the Storm is better, but I too have no data
one would postulate a smaller source

Re: Industry heatsink+TIM testing@frostytech
 

"one would postulate a smaller source"
Whilst I am postulating that with progressively smaller sources the Storm gets worse(link and link).The attachment in second link is particularly illustrative.

hmmm
are we not assuming at least some spreading ?
lord this is a mess Les

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
