I recently disassembled my Celeron 433+Heatsink/Fan. I was interested to see what kind of thermal grease/interface material was sitting between the CPU and the heatsink. I found a square patch of interface material which sat directly over the core of the CPU.
I was puzzled about the appearance of the CPU. My Celeron 433 (Mendocino core, according to Tomshardware) looks like this:
-A smooth rectangular metal piece in the center (the core, I assume) on which sat the thermal interface material and then the heatsink.
-The core is sorrounded by rows of pins.
The strange part (to me anyways) is that the core is raised above the pins. When the heatsink sits on the core, there's a big air gap between the CPU and heatsink on the outer perimiter of the CPU where the rows of pins are. Shouldn't there be a ceramic top to the CPU?
From all I've learned about cooling and how important it is to have contact between the CPU and heatsink, I have to wonder if this is negatively affecting heat transfer.
Should there be an air gap there?
Should I get some thermal grease and coat the outside rows of pins of the CPU?
Is this negatively impacting heat transfer between the CPU and heatsink?
Thanks.
