Recently I have been debating the merits of fillers in Thermal Interface Materials (TIMs) over unfilled TIMs. There seem to be two schools of thought on the matter:

1. An unfilled TIM displaces air in the micro pores between mating surfaces therefore increasing the contact area and therefore bettering the thermal conductivity. Adding a filler to the TIM would increase the separation between the two surfaces and actually decrease the thermal conductivity compared to the unfilled TIM. 

1. Fillers Increase the thermal conductivity because of their own conductive properties and the TIM is just a “support” to hold these particles in a suspension for good application. A TIM with a more thermally conductive filler will be a better TIM than an unfilled TIM because of the good Thermal Properties of the filler.

This problem has been of great interest to me lately as I plan to build a computer and need to choose the best TIM to ensure good heat transfer from the components to the heat sink and am stuck between unfilled or filled TIMS. Does anyone have any incite into TIMs? Can anyone help?

Here is the computer demonstration video:

Anyone with Adobe Illustrator can see all the layers, I did it myself.

Why it had to be cleaned up for hours is beyond me.

Mine is white on black from microfilm, and hard to read, so what...

My theory on how this would work is that say you have the physics set up to produce tacyon particles. Then you have a network that you know they will follow at superluminal speeds. Would they interact (that is tacyons interact with tacyons)through that network? Then when the network is finished its calculation.

it would have to interact with a stream of newly created tacyons particles because those that are already calculating would be impossible to tell when they where finished. Those finished calculations would then interact at a somewhat random time when finished calculation, true given calculation of superluminal velocities you would be able to calculate aprox how long things should take.

As we can see today we are using ddr3 rams, when we can see ddr4 ram?

can we use ssd technology in ram or can we use pci express technic in ram ?

Why not keep them all in the same pattern instead of swapping the top and bottom lines over?

There is a light experiment where a coloured disk with equal red, blue and green sectors is rotated. As the rotational speed increases the coloured sectors coalesce into a white disk, thus demonstrating that white light may be considered to be the sum of three primary colours.

I tried doing this using modern technology - a coloured disk rotating on a computer screen. It didn't work, no matter how fast the disc notionally rotated. I seemed to be getting a slow  stroboscopic effect rather than coalescence. 

Is this caused by a feature of computer screens? 

I thought that computer chips are made out of silicon, a semiconductor. I've read that the resistance of semiconductors decrease as the temperature increases. Therefore, wouldn't the performance of a chip be increased as the temperature increases?

I am looking at the top500.org Performance Development chart of supercomputers since 1993. What's interesting is how the No.500 spot has improved in remarkably smooth increments since 1993; while the No.1 spot has not - rising in distinct steps. This makes sense I guess, the lumps and bumps of innovation, etc. All that fresh air at the top of the mountain. Naturally I can't help wondering though, at what position would the graph change from one to the other.

But my question really is, is this a generalisable phenomenon? So, say, that in any given rankable performance is there a level at which the rate of improvement is predictable?

Or to put it another way, how good do you have to be to be unpredictable?
