Adding new thermal paste on the i7 3770K? (Delidding)

[GTAPC]

Well for my first build I did not open up the i7 3770k chip to add new thermal paste and let it slide with stock, I'm building a second rig for a friend to which I have already bought the parts just yesterday. Here is what I'm building:

For those who don't want to go to link:
CPU: i7 3770k
Mobo: Asus Sabertooth Z77
CPU Cooling: Corsair H100i
Graphic/Video: 2x GTX 760 2GB Sli
Case: Fractal Design Define R4 w/window (black pearl)
PSU: OCZ ZX 850W 80+ Gold Certified
Optical Drive: Asus BW-12B1ST/BLK/G/AS
Monitor: BenQ XL2420TX 120Hz 24.0" Monitor

My question is, I keep hearing that the stock cpu's thermal paste is not as good as it should be and causes Ivy Bridge's cpu with heating more than Sandy Bridge, and I was informed on this video here that putting a better thermal paste keeps the heat at a bit lower temps? I believe this guy refers it as delidded?

i would not recommend that you attempt to delid your cpu.

when he means delid he means removing the integrated heat spreader.

just apply some aftermarket themal compound to the cpu and remove the pre applied stuff on the stock heatsink.

use the rice grain in the middle method and do not spread for the best and easiest results, place the heatsink down squarely onto the cpu and give it a slight couple of twists while pressing down to help spread the paste and then clamp it.

dont lift off your heatsink or you will need to clean and reapply the thermalpaste.

Alright, I guess I can do that as I was already going to use after market thermal paste, was just wondering why delidding is not recommended as I hear it gives slightly better heat temps. Does delidding remove warranty?

delidding voids your warranty and it is quite easy to bin your processor by cutting too deeply or by hitting some of the surface mounted resistors on the surface of the cpu under the heat spreader.

The problem is not so much the thermal paste Intel uses, it is more the thickness of the RTV they use pulling the integrated heat spreader and silicon die slightly apart.
When you delid the CPU, the RTV is also removed which allows for a much better IHS to die contact.

You can locate some good Delidding Information Here.
Be warned though, delidding will 100% VOID YOUR WARRANTY and, improperly done, destroy your CPU.
This is not for the faint hearted or someone who can not afford to purchase a new CPU if the worst happens!

That said, the Vice Method does seem pretty straightforward.
If you decide to risk it, just be sure to look through the guides twice and double check the CPU orientation before you start opening it up.
