Kitguru just tested seven thermal pastes; Arctic Silver 5 and Céramique 2, Cooler Master's MasterGel Pro, Cryorig CP15, EKWB Ectotherm and Thermal Grizzly Kryonaut. They wanted to see what performance difference, if any, existed between them for no matter how effective your cooler is, it can't dissipate heat that is not transferred to it from your CPU. Their test was conducted with a i7-4790K CPU and Cooler Master Hyper 212 LED CPU Cooler and the results show that the incumbent is not necessarily your best choice.
"Following on from our previous articles about fan configuration and static pressure vs airflow fans, today we are looking at thermal paste. Specifically, we are hoping to find out whether or not choosing different types of thermal paste actually makes any difference. To do this, we test 7 products from 6 companies to see how much difference thermal paste really makes."

Sorry for being about a month late to this news. Apparently, someone got their hands on an Intel Core i7-5960X and they wanted to see its eight cores. Removing the lid, they found that it was soldered directly onto the die with an epoxy, rather than coated with a thermal paste. While Haswell-E will still need to contend with the limitations of 22nm, and how difficult it becomes to exceed various clockspeed ceilings, the better ability to dump heat is always welcome.

While Devil's Canyon (Core i7 4970K) used better thermal paste, the method used with Haswell-E will be event better. I should note that Ivy Bridge-E, released last year, also contained a form of solder under its lid and its overclocking results were still limited. This is not an easy path to ultimate gigahertz. Even so, it is nice that Intel, at least on their enthusiast line, is spending that little bit extra to not introduce artificial barriers.

Efficient cooling has always and will always be a limiter on the power of processors, especially as the processes used shrink and transistor density increases. Over the years we have seen heatpipes become common and watercooling move into the mainstream with the advent of all-in-one coolers. Thermal interface material has not changed much, even though we have heard of many developments nothing has been released to market. Carbon black proved to be too long in development and might be replaced by nanotube forests though there is do it yourself thermal paste doped with diamonds that you can make right now.
From there we saw a project doping thermal paste with graphene, which could provide conductivity of up to 600 W/mK once it becomes available, hopefully in sheet form for easy installation. Increasing the thermal conductivity of your TIM is a good thing, assuming that the heatsink absorbing the heat can keep up with the transfer which is what makes the news out of FrostyTech so interesting. Researchers are sandwiching a material they call K-Core Annealed Pyrolytic Graphite in between layers of aluminium and other metals to create a heatsink with a thermal conductivity of up to 1092W/mK in certain situations. It is not as simple as doping a heatsink with this new material though, it is only efficient at moving heat horizontally. Read on to find out more at FrostyTech.
"When the thermal conductivity of copper and aluminum heat spreaders just won't cut it, the future revolves around a material called Annealed Pyrolytic Graphite. Let's consider the numbers: where a solid aluminum heat spreader has a thermal conductivity of 126W/mK, the same heatspreader with an Annealed Pyrolytic Graphite core would see thermal conductivity on the order of 1092 W/mK. That's not a typo."

Say goodbye to messy thermal paste and the time you spent cleaning up the goop that ended up somewhere it shouldn't thanks to Sony's new thermal sheet. In fact it looks like this new thermal interface material is so easy to use you could do it blindfolded! The demonstrated performance is equal to that of traditional thermal paste, with Sony claiming a much longer effective lifespan. At 0.3mm thick it will also provide a thinner layer of TIM than even the most practised of us cannot match by hand. Check out more at Slashdot and try to avoid the rootkit jokes.
"Sony has demonstrated a thermal sheet that it claims matches thermal paste in terms of cooling ability while beating it on life span. The key to the sheet is a combination of silicon and carbon fibers, to produce a thermal conductive layer that's between 0.3 and 2mm thick. In the demonstration, the same CPU was cooled by thermal paste and the thermal sheet side-by-side, with the paste keeping the processor at a steady 53 degrees Celsius. The sheet achieved a slightly better 50 degrees Celsius. The actual CPU used in the demonstration wasn't identified. Sony wants to get the thermal sheet used in servers and for projection units, but I can definitely see this being an option for typical PC builds, too. It's certainly going to be less messy and probably a lot cheaper than buying a tube of thermal paste."
