What....? Can you please rephrase your question.. I don't understand. But if you're trying to say, "can I spread it on my heatsink first?", then yes you can also do that but it is usually done on the cpu. BOth ways would work I believe. Because on some Hyper 212's, it is advisable to spread thermal paste on the heatsink first and on the gaps, rather on the cpu itself.
that means may i have to use some thing to spread that material or any trick to apply the paste ?
