Alright, just got my CM Hyper 212+ cooler for my CPU and I had a quick question about thermal paste application. First of all, I'd like to use IC Diamond instead of the provided thermal paste unless there's a compelling reason to use the stock stuff. Secondly, I was wondering what the best application method is with this kind of heatsink (direct contact heat pipes)? I know that IC Diamond is meant to be applied as a dot and then spread by the pressure of the heatsink and that worked well when I used it on my laptop GPU and CPU and with the stock heatsink on my desktop. Should I apply the paste differently with this cooler (pre-spread or anything like that)?
IC Diamond is fine to use if that's what you want to use. The stock paste that comes with this cooler is actually pretty good too though. We're talking about maybe a 1 degree difference if applied properly...
This cooler is different than most being a direct heatpipe contact type. As you probably immediately saw, the surface is not a smooth one like other traditional ones, so yes...application of thermal paste is done differently here for optimal results. I have used this cooler on a few occasions for builds I have recently done for people. I followed this guideline by ap42 to apply it:

I don't think either matters to be honest. The pressure of the plate on the CPU will spread it out, but I prefer to make sure that I've done it well myself.
I have the same CPU and I used the stock paste, but I'm sure that won't matter. I'd have thought it'd be better to use a 'better' brand of paste. I put a pea sized dot on the CPU and spread it with a small peice of card.
Pre-warning though, the heatsink was a bastard to screw to the Motherboard, but that's partially down to my use of Scissors in place of a screwdriver.
The dot and spread method is not ideal for this cooler. The surface of this cooler is not smooth at all due to the gaps between the heatpipes and thermal block. You may have a lot of gaps and bubbles between the interface of the two. If your temps are bad, highly suggest you re-apply based on the links I gave above.
