...You've never built a PC before have you. In ten years of building custom PCs and doing PC repair as a side job, I have never, ever ran into "thermal glue". Never. I've taken apart Dells, Emachines, Compaqs, Laptops (that was for fun though, it's still in a million pieces in my closet), on and on, and built tons of machines for myself and others. If TIM is used, it's the same old stuff, just twist it a little and the heatsink comes right off. And did you know that on all modern systems, the heatsink completely covers the CPU? You cannot get access to the clamps that hold the CPU in place. If the thermal paste did glue the heatsink to the CPU as you claim, no one could replace their CPU, ever. That would be a pretty dumb design for a user installable part now wouldn't it? It's so dumb, even OEMs don't do it.
You've never experienced a moment of intelligent thought before, have you?.
Quote:As for "scraping it off and repolishing the heatsink", you have obviously never worked with TIM and heatsinks. Just put some alcohol on a rag and it wipes right off. No "polishing" required. Stock fans, purchased fans, they are all the same, just wipe it off you have a nice smooth surface to put some Arctic Silver onto.

This stuff CANNOT be wiped off, no matter how much alcohol you wipe it with.
I have seen this stuff not only rip off IHS from intel and amd cpu's, i have also seen it rip pre LGA socket cpu's from the socket. It cannot be wiped off of the die and melts its way into any gap it can.

Stopped? No. Hindered? Yes. Thermal Paste is not as good a conductor as solid metal. Here's a tidbit from that article you didn't read.

Thermal Paste allows you to have a temporary connection between two metal pieces. It's not the best, but if you keep it down to just one TIM bridge, it's not that bad. The problem with having TIM connect the die to the IHS is that you are increasing the number of times thermal grease is used, and decreasing the thermal dissipation rate. THAT is why this is bad.
Completely out of the context i was going. reference was towards IHS/DIE contact to the mounted cooler.
Shamino has verified that the high temps with Ivy Bridge are due to the use of TIM between the die and heat spreader instead of conductive solder
