If you are advertising I will try it out. I do not have any CLU or other LM on hand at the moment. I was going on the advice of @Roboyto
and planned on removing the stock glue, keeping the stock TIM. It was part of my new custom loop install. The custom loop went in okay, the delidding, a stubborn mule.

You should still see an improvement in temperatures even if you don't swap the paste out. Intel did specify the 4690/4790 received upgraded thermal paste, so that could be something. The Intel paste is also kinda thick so it may not suffer from pump out like traditional pastes.
IHS Gap Performance Gains:
I have used a razor on all of my delids up to this point. My first attempt with a razor knife was also a failure as I was anxious/nervous/scared. However I found that a standard razor blade is best. You could probably benefit from heating the IHS, or razor blade, a little bit to get through the glue a little easier, though I haven't tried this yet myself.
The hardest part of the razor method is getting it started. I've found the best strategy is to use the center of the razor to get under a corner of the IHS. By using the razor at a slight angle you can usually get under the corner pretty easily as the glue doesn't go all the way to the edge. Once the razor is under the corner you can slowly push the rest of the blade under the edge of the IHS.
Generally speaking the glue is thickest on the 'wings' where the socket latch pushes down to secure the CPU.
A thought I just had was the use of some fishing line or possibly dental floss. I say this because it is how I have removed emblems from cars before...use a hairdryer to heat up the glue holding it on and then slide the line behind it to remove them without damaging anything. If you can get a corner started with the razor first this may work...use a small heat gun or hair dryer to heat up the IHS and then see what happens.
If you do decide to cut it off, just be sure to keep in mind where the VRMs are under the lid! Use the gold arrow and/or dots on the PCB to know where to be the most careful.
