CPU help????

I have a dual-core processor (pentium D), when apllying the thermal paste, should i spread it across the cpu or just have a line across the cores? Which is more efficient and why???

you should spread it evenly

i have done many tests and best way to apply thermal paste is to spread it as thin as possible acrros the entire surface
then put a small dab in the middle and spread it toward all sides

why?

the themal compound must work hard to move to a new surface that is why you spread it across the entire area - wetting!

you mound it in the middle so it can fill the voids and flow evenly - tested and proven!
