I don't know about User friendly, but the Indigo extreme has been by far the best performing thermal material for a while now (in my own personal experience), and also the most expensive. as for Intel only... these things are pre-cut, and I am not sure what the results of trying to trim it yourself would be. that aside, for Indigo material to work properly, you're literally MELTING it between your CPU'd lid and your heatsink (you're suppose to run your system with the fans OFF), and then when your system cools down it will re-solidify, thereby seamlessly connecting your CPU to your heatsink. since AMD CPUs are a bit lacking in the thermal protection department, you could cook your AMD chip before this material works properly...Like i said before, not the most user friendly stuff. but when done right, it's the best thing next to soddering

This seems extremely interesting. If it works properly, and does outperform common paste, then I'm looking forward to the responses from other companies, probably with similar solutions. The fact that it is only available for Intel at the moment is a downside but they *probably* have their reasons for that.

Hmm... some sort of gallium/silver alloy? The thermal transfer between the die and the heatsink is only good as its weakest link and the TIM used by intel underneath the IHS for ivy bridge and haswell is not very good.

If this material is so good, why not get rid of the CPU's headspreader and have this thingy straight on the CPU die? Can it be used on GPU memory chips? Maybe the stupid laptop manufacturers can put this thing instead of the cheap thermal pads on chipsets...

I have used this for the last two years on about 6 different applications. The first attempt was a failure as the liquid seeped out from under the CPU cooler (it was my poor application, not the product's fault). It can be removed - think solder-type material - but of course is a one and done application. As stated above you have to run your system up to a specific temp for a period of time to reach the melting point. I have found it cuts a couple of degrees off my higher end gaming rigs from any other paste product.

Makes sense... although, don't metal-based solutions degrade faster than non-metal solutions?Also, if this is solder-like, doesn't solder have the problem of becoming amorphous under high temperatures and flowing slowly, causing problems down the line? Isn't that kind of why Intel went against simply soldering its CPUs to the die, due to the possibility of the solder degrading?Also, this version supposedly has "phase change" properties. Does that suggest vapor-chamber like workings, effectively removing hot spots and spreading heat evenly across the contact area (which would dramatically improve performance in some coolers, especially heat pipe direct touch coolers), or does this simply mean it maintains more consistent temperatures by using the chemistry of a phase change to dramatically increase the heat capacity of the thermal interface itself, in which case this doesn't really mean much except in burst use scenarios?I'm always intrigued by the idea of giving CPUs TDPs like what we see in GPUs by removing hot spots and providing better thermal interface to decrease deltas between CPU temp and heatsink temp, but so far, everything seems so incremental, and really not worth the extra effort.
