Bit of a noob question, but thought I'd ask here to try and get the opinions of 8 Pack and other CPU savvy folk of this sub-forum.
I have an 5820K. What's the best way of applying the thermal paste considering this is a largish CPU?
The pea dot? The cross pattern?
And should I somehow try to avoid the little hole getting clogged?
I have a Noctua NH-D15S cooler and will be using the Noctua paste.

Opinions very welcome!

Thanks
 
Any more advice about that little hole?
And Kelt - your X recommendations span the forum! When you apply it how far do you extend the arms of the cross? Doesn't the X method make it more likely that that hole will get filled?
 
That little hole is left over from production process from what I have read. It's to let the gasses escape when they are soldering, and it's fine for thermal paste to get into it.

Edit: Apparently it's there for a thermal probe, too?

Not sure which is correct.

I used the X method on my 5820K. I had to change the cooler (Noctua NH-D15) a week later, and I noticed that the thermal paste had been dispersed sideways, with none in the middle. I've read that the Haswell-e chips are slightly convex, which may explain this. The paste had spilled off the sides of the CPU, so when I fitted my new cooler (Noctua NH-D15S - better PCIe 1 clearance), I made sure the lines were as thin as possible, and did not extend too far into the corners. Temps are the same in both cases, so no issue I guess!
