Aqua Computer and Rockit don't want you to keep your hat on

Delidding a Kaby Lake processor such as the i7-7700k does not offer the same overclocking advantages as with previous generations when replacing the TIM gave you more headroom.  Instead of being able to push your CPU past 5GHz, popping the lid off of a Kaby Lake reduces operating temperatures and likely extends the life of the processor ... or immediately ends it.  If you don't have a 3D printer handy to make your own delidder, then take a peek at this review from TechPowerUp.  They try out two delidding tools, one from Aqua Computer and one from Rockit which Morry has used; do be aware that any CPUs killed as a result of reading their review is the responsibility of the one who delidded.

"Intel mainstream CPUs have had a bottleneck in cooling due to poor heat transfer from the CPU die to the integrated heat spreader. Thanks to new de-lidding friendly tools released recently, it is now easier than ever before to handle this yourself and get a cooler running CPU. We examine two such solutions from Rockit Cool and Aqua Computer today, both of which promise fool-proof de-lidding and re-lidding"

Living dangerously; delidding your i7-7700k

Recently [H]ard|OCP popped the lid off of an i7-7700k to see if the rumours that once again Intel did not use high quality thermal interface material underneath the heatspreader.  The experiment was a success in one way, the temperatures dropped 25.28%, from 91C to 68C. However the performance did not change much, they still could not reach a stable 5GHz overclock.  They did not let that initial failure discourage them and spent some more time with their enhanced Kaby Lake processor to find scenarios in which they could reach or pass the 5GHz mark. They met with success when they reduced the RAM frequency to 2666MHz, by disabling Hyperthreading they could reach 5GHz with 3600MHz RAM but only when they increased the VCore did they manage to break 5GHz. 

Of course you must exercise caution when tweaking to this level, a higher VCore will certainly reduce the lifespan of your chip and delidding can have a disastrous outcome even if done carefully.  If you are interested in trying this, The Tech Report has a link to a 3D printed tool to help you in your endeavours.

"Last week we shared our overclocking results with our retail purchased Core i7-7700K Kaby Lake processor. We then took the Integrated Heat Spreader off, replaced the Thermal Interface Material and tried again for 5GHz with 3600MHz memory and failed. This time, less RAM MHz and more core voltage!"
