Is it worth buying? I'm not sure if it has much larger cooling capability compared to other thermal pastes, though I know for sure that Gallium is much more conductive compared to silicone or diluted silver.
I'm confused, if the Coollaboratory's paste is conductive, wouldn't combining aluminum with copper be a bad idea? I'm also hoping the paste won't eat through the aluminum heat spreader after several years of usage.
"Warning: The Coollaboratory Liquid Pro and Liquid Ultra were not run on my Intel 2500K water testing simply because I had no intentions of loosing my CPUs 3yr warranty, removing those liquid metal thermal compounds is an undertaking, which will cost you your warranty.
The packages clearly state warnings that the products are electrically conductive, are not to be used on aluminum, and will void your warranty, once I saw the results of removing it from the 965BE, I decided not to run it on my 2500K, the package contents has the TIM in a syringe, application instructions, 2 application brushes, 1 alcohol pad, and 1 abrasive cleaning pad. "
If that applies to your system, then get one of the others. As you can see, there is not much performance difference. I've had success overclocking my E8400, E8600, and Q9650 with Arctic Silver 5 and with Arctic Silver MX. (I know they are older chips, but they work very well on my systems.)
My system is an N61jq laptop. The CPU and GPU don't have a heat spreader on it, just a black square and a copper plate with heatpipes.
I've been thinking about replacing the thermal paste since some users of the laptop complained that the paste was dry after two years of usage. Others complained that for some reason, there's some kind of a plastic film between the CPU and the thermal paste. I also plan on using thermal paste to attach small copper heat sinks onto the heat pipes.
The load temperature is mid to high 70C, used to be low 90C before I took off the suffocating back plate (it only had a few slits for air intake) and added a laptop cooler. Upgrading the fan or heat sink isn't an option, so I want to reduce temperature through other ways.
I have an old Dell Inspiron 6000 (laptop) that I got a couple of years ago. I used Arctic Silver 5 when I took it apart to clean it up. I haven't run any temp tests on it, but it works well and doesn't get hot.
I wouldn't apply any liquid TIM to a laptop - a little in the wrong place could really mess it up.
