Hi all,

Decades-long customer but long time lurker here :D
However I thought I'd post up my results from delidding my 7700k in case anyone was like me and on the fence about whether or not to do it (of course YMMV).

7700k stock, under Corsair H105 AIO: http://vault.dvs.scot/7700k stock load.png

Purchased der8auer's kit and some Conductonaut (along with the Arctic Silver cleaning kit), made in my opinion a hash of the delid / repaste job, BUT: http://vault.dvs.scot/7700k delid load.png

Amazing -30C load temps, replicated in other workloads. All I can say is thanks OcUK for stocking the quality components needed here and the usual rapid delivery! (and haribo :D)
 
What adhesive glue is everyone using. I was gona do mine, got everything bar the glue to re fit the lid. What is best available in our local retail parks/high streets ect. Something I can pick up without ponsing about online. Went to B&Q yesterday for example and just looked for something that would say Sillicone gel glue or close ect. But it`s all just brands and not clear if these products are conductive, much less have any decent thermal properties. Looking around internet forums is populated with products that people not in this country seem to have better access to. What are you using, what do people recommend?
 
Thanks all!

Great results. What were the delid temps like after running full load for the same length of time? I noticed the stock test was run for nearly 5 minutes longer.

I let it run for 10-15 minutes and it was static at those temps :)

rossiboy001: I used a dab of gorilla super glue either side of the IHS (on the thicker parts), spread it out with a toothpick so it was extremely thin - I read that it's not so much Intel's choice of TIM but the thickness of the adhesive that causes a lot of the heat transfer inefficiencies. So careful on this point.

Thanks for the reply dvs8. Im a bit concerned with using a superglue just in case i have to re delid. Also is it a good idea with what ever product it is, even your superglue to put some on those contact silver points near the CPU just in case any liquid metal runs off, that they are covered and thus the liquid metal cannot touch them?
 
Wow. I'm quite sceptical about delid claims, have seen videos both very pro and meh, but your results are seriously impressive
 
I still don't understand why Intel are still using rubbish TIM, up the price 50p and use something good!

I use black liquid gasket which is similar to the stuff Intel uses. I use Wynns liquid gasket because I had a big tube from when I did the sump on my car but this one will do the job just as well. Just put a little around the inside edge of the IHS like Intel does and place it back on the cpu, fit it to the motherboards cpu socket and put your finger on it when you lock it down. Tighten the cpu block up and it will fully set in a couple of hours. You don't have to worry about the IHS coming off when you next remove the cpu then.

My 4790k was hitting ridiculous temps so I borrowed a delidding tool from a member on here and took the lid off. Intel's thermal paste had gone as hard as concrete so no wonder the temps were poor. Cleaned it all up put on some CLU and stuck the IHS back on and it dropped my temps by 25 degrees C. I had previously done my old 4670k and saw drops of 15-18 degrees C on that as well. It seems even more relevant with the 8700k which is a disgrace really as they charge us extra for unlocked K series cpu's so the least they could do is use some decent thermal paste in them!!

As pastymuncher stated just get some generic black RTV gasket silicon. If you use der8auers delid tool it comes with a clamp to lock the IHS in place once it has been reapplied to a give the silicon time to cure.
 
What are you doing with your much cooler running CPUs? ie using the thermal headroom to push the CPU harder or enjoying the presumably quieter operation of the PC, even when under load.

Because it's not about saving money on TIM, it's about gimping performance and longevity to force upgrades.

Remember the beast that was Sandy Bridge? Stratospheric leap in performance, could overclock to Hell and back and ran pretty cool because of the soldered IHS. And ever since then with the incremental upgrades Intel has been giving us, how often do we see on enthusiast forums "meh, not much point in upgrading from my overclocked i7 2600K".

Intel gave away ridiculous amounts of performance and removed any necessity to upgrade. Coincidence then that Ivy Bridge was the first to use toothpaste instead of solder? So now you pay a premium for K series chips, but still can't get the longevity out of them by overclocking to match the next gen because the TIM is rubbish and the IHS is wonky.

That's always been my interpretation anyway. Decent TIM is not in Intel's profit interests.

I have seen advice saying not to re-seal the IHS because it can kill performance.

It's not alive. How can it kill performance?

If you don't re-seal it, it just falls off if you open the the CPU catch on the motherboard (if your case is up right) it makes no odds if you do it or not.
