And since none has pointed it out to you yet, only use a really really really small amount so you dont "lift" the heatspreader to high from your cpu die smile.gif and you dont need to glue all 4 sides, only 2 or 4 corners.

But if you get rocket88 delid kit with the relid kit to it. Delid and do the cleaning etc, put the headspreader back on and use the relid kit to hold the heatspreader in place. then use Super glue gel with 1 drop in eatch corner and you are all done smile.gif

I do have the reliding kit, was just planning on setting in the jig and putting 4 small dabs of rtv gasket sealer on the corners. Just enough to hold the lid in place till I transfer it to the socket.

all this talk of delidding being a neccessity on the newer chips almost has me convinced to delid my 4770. it ocs like a turd. 4.2 max regardless of voltage, then again i would mostly delid for just better temps.
post #23 of 34
CPUs that have a significant delta between cores are typically the best candidate for delidding. Dont go in assuming you're going to drop 30° if your cores are all within a degree or two while loaded. In the case of my Skylake, there was a single core that was approximately 5° warmer than the rest so I opted to go ahead with the delid (which was very simple even by hand using a razor blade). In the end, package temp wasnt much different but all of the cores were much closer together. Just something to keep in mind before you decide to go forward.

I would say there are 3 cores within 5 degrees of each other at any given time but there seems to be 1 core that is anywhere between 5 and 10 degrees hotter than the rest.

Currently I have 2 cores that have max temps 10 degrees higher then the others. Also changing my CPU PLL voltages dropped my max temp by 5° already.

Sounds like you have a good candidate for a delid. Assume that the lowest cores could be making good contact, and that the higher cores will meet the temps of the lowest cores win a degree or two after the delid. Sometimes there isnt a whole package drop in temps, but much less variance in temperature.

Before you decide to delid, you can try removing the cooler and reinstalling it with new thermal paste to see if the core temperature variance changes. If so, it could be a bad mounting of the cooler or thermal paste spread that exacerbates the core temp variance. I personally dont feel that it will make much difference, but its worth a shot. I remounted my cooler 3x to check how the thermal paste spread on it before I delidded. This way I knew how to mount the block for best spread once I had delidded.

I used the rockitcool88 delid kit and relid kit.

 

I used this for my cpu. At 1.3 volts max temp 100% load I get 60c

Out of curiosity what case are you using that the 360rad mounts that way. I am asking to make sure it has a vent on the other side for the air to blow through and that you not just closing up a rad inside a case.

Yep here is an image of the backside of the case.


Did my delid last night and so far my max temp has dropped from 80°C to 60°C. Going to try to hit 5.0ghz today and see where I end up.
