Well I’d say put soem MX2 on the heatsink base, spread it out using a razor blade, only enuf MX2 to fill the gaps b/w the pipes. later go for big-pea in the centre method on the processor.
or, a bigger pea on processor would be even better
check Xigmatek web site they may have tips for instalation.
i read it once ,
APPLY PASTE ON HEAT SINK BASE ,make sure to fill gaps between the heat pipes , then apply paste on proccy n u rdone for it…just fix it taking care no any bubble remains (forms) .
some web sites clain that design of base as this heat sink has (direct heat pipe exposure)is more efficient than plain base plate ones…n also it reduces companys fabrigation cost.
I have tried everything. And best contact is achieved by this method.
Draw 2 lines of thermal compound where i have marked them in red and slap it on. Achieved perfect square pattern on the IHS of the CPU covering everything.
