Also between IHS and cooler? Or just die and IHS?
Agreed on price performance. Like Bonkers, i just bought it to try it out. It's definitely better than arctic silver 5

Haven't tried anything else. I don't change paste that often.
liquid tim is most efficient between Die and IHS, some people use metal on this part and then MX4 between IHS and cooler. For me though I just use it on both. I actually think someone posted that the most efficient test result was this:
Thermal Grizzly conductonaut in between die and ihs
Themal Grizzly Krynaut in between ihs and cooler.
It is possible to go even lower still. For example, EK sold naked Ivy mounts meaning you ditch the IHS altogether. When I did this with my 3570k I dropped temps by a massive 24C. Downside is that devils canyon ran too warm to do this effectively, and EK dont support any later generation CPU passed ivy bridge with their naked mount. So I do not recommend going naked die anymore until they design a safe mount to do so.
There will always be risk involved for those who splash it on too much. If you get overspill once the TIM is under compression and it touches any chips. It will conduct and short circuit your die! You can however slap some of your wives/gf/sisters nail polish (clear) on the chips and that will protect them from contact.
There are more cons than pros for liquid metal but I would still choose it over normal paste
pro:
*best results and highest temp drops
*never need to reapply it
cons:
*cant be used on aluminium
*possibly expensive
*pita to clean off if you decide to switch back to paste
*pita to spread if not used to it
