4790k Delidding

[CalVic]

Yoh,



My 4790k has always ran extremely hot, after two years or so it would always thermal throttle even at stock voltages. It's been in a custom loop and a few AIOs since. When I first had this puppy back in '14 she'd clock to 4.8 @ 1.215v - 1.22 and was cool cucumber.



I know it's an old chip, but I feel she's quite a golden 4790k that has always been held back and I just want to put it to bed, once and for all.



So I purchased a Die-Mate 2 that should be here this week, I have a few questions:


Is there any TIM that is a no-no (abrasive stuff, such as Diamond)?


I really cannot be bothered to glue the IHS back on, any issues with inserting the chip in the board, then placing the IHS on top and closing the socket? (I feel this method would make it easier to replace the TIM)



Should I just bin the IHS and opt for a Delid guard?






Cheers!

I've had mine 4790k delided for years. When you pop the IHS clean the silicone glue thoroughly. There is no need for liquid metal. 4790k is not that hot, and the lm is quite messy. I would recommend Thermal Grizzly Kryonaut both under and over the IHS.

You should also lap the IHS. It is amazing how it gets warped over the years. Take a piece of glass 400, 600, and 800 grit paper and sand it until you have a uniform copper surface.

When you put it back without the glue spread the paste over every part of the die in a nice thin layer, put the CPU in the socket, and place IHS on top. While closing the retention mechanism make sure to hold the IHS firmly with other hand. It will slide. But when the mechanism grabs it, it is as good as glued.

Thanks Will take those points onboard.



May give the lap a miss to begin with, knowing my luck I'll warp it even more.


Will certainly be picking up the thermal grizzly and will update this thread most with results

Good luck.
