You only need a tiny amount of it because they are only there to fill in microscopic valleys, not act as the heatsink or waterblock itself. No surface is flat. Even if you sand them down on both the heatsink/waterblock and the cpu, there's still some microscopic valleys. They just become less noticeable to the human eye.

So after a few hours of playing Skyrim I checked the temps and I saw this:

I tried looking up what a PCH is and didn't seem to find a conclusive answer as to what is an acceptable temperature or if this is cause for alarm. When I first started up Speedfan immediately after Skyrim the GPU and all of the cores had that little flame icon too with a temp of mid 40s I think but only for a second, then they dropped to what is in the screenshot.

Should I be worried or is this within acceptable ranges? The GPU is a Geforce 560ti if that matters.

That's the Platform Controller Hub (more or less handles "southbridge" functionality like the USB and SATA ports, most PCI and PCI express slots, and most other peripheral components; interfaces directly to the CPU). Intel also manufactures this silicon.

You can see Intel's guidelines here:

Tj,max = 108C
Tcase-max = 104C

Sounds good to me. That Tcase-max is like 30C over what they specify for the CPUs.
