Core i7 7700K TIM replacement improves 5GHz OC temps by 30 degrees

While Intel has yet to officially launch its Kaby Lake desktop CPUs, plenty of people seem to have got their hands on the Core i7 7700K already, with plenty of benchmarks already floating around the web. One of the worrying aspects about these early reviews has been reported temperatures, which seem to be quite a bit higher than Skylake and this week, someone may have figured out why as one user claims to have delid their 7700K to replace the TIM, which has dramatically improved temperatures while overclocked.

User ‘RichUK' on the Anandtech forum has managed to get an early 7700K retail sample and has managed to get a 5GHz overclock on it. While running at this speed with a Kraken X62 AIO cooler, the CPU would hit around 90 degrees Celsius under full load but after delidding the CPU and replacing the Thermal Interface Material (TIM), temperatures have dropped to a much more reasonable 64 degrees Celsius.

This suggests that perhaps Intel has been using poor quality TIM for its new Kaby Lake chips, which as wccftech pointed out, is an issue that has popped up before and was eventually fixed with the Devil's Canyon Haswell refresh. All of that said though, it is also worth keeping in mind that temperatures for Kaby Lake may also be a bit higher compared to Skylake due to the new stock clocks. The 6700K ships with a 4.2GHz boost clock, whereas the 7700K ships with a 4.5GHz boost.

KitGuru Says: Things are still pretty early as far as the Core i7 7700K goes, so more testing will need to be done across a larger user base before we can be sure about any of these early findings. That said, for enthusiast overclockers, early indications seem to point towards delidding being the way to go for these chips.

  1. I delided my 4770K, you think they would have learned what they learned before lol

  2. i need to upgrade, but if this is the crap intel is pulling with their new chips i’m going AMD. i’ve no urge to try to delid my CPU just to fix an issue the manufacturer caused.

  3. Stop being cheep to save a few pence intel abd solder the chips again

  4. Wrong. The first benchmark was done with a thermalright 6 and the second was with an x62. Stop with this bs.

  5. Actually the second was done with a corsair h110 and the 3rd was done with the x62 so calm your tits, everyone gets things wrong sometimes.

  6. Google is paying 97$ per hour! Work for few hours and have longer with friends & family! !mj327d:
    On tuesday I got a great new Land Rover Range Rover from having earned $8752 this last four weeks.. Its the most-financialy rewarding I’ve had.. It sounds unbelievable but you wont forgive yourself if you don’t check it

  7. ‘Calm your tits’. Comment of the week!

  8. This is seriously lame and cheap skate from intel..greedy to save a few pennies.
    If you buy it them they have opened a can of woopass on you….they did this before with ivy bridge as well

  9. Btw…AMD is King now ….faster and more competitive and they can ask any price they want

  10. I hope the high end mobile CPUs will be very high clocked beasts too, not just desktop! 3ghz base 4ghz turbo would be great for the 45w level.

  12. I’m going Ryzen as well. Intel CPU’s costs as much as gold ingots and they use cheap TIM? Intel can go f’ & ‘uck themselves.

  13. Basically its confirmed its a skylake architecture overclocked on a smaller dieshrink. rip Bintel fans

    pretty interesting considering the difference between most thermal pastes is like single digit temperature differences. It seems weird to me a 30 degree difference is possible based on thermal paste. They must have a reason other than saving mere pennies like keeping the paste stable over a long period of tie or something for average users.

  15. AMD is king now? Lol.
    Until they release something that can beat all of Intel’s i7 extreme CPU’s or even just the mainstream i7 CPU’s, AMD will never be king lol.
    Must be trolling…

  16. I did the same with my 4770K. While doing so, I knocked off a few golden chips inside. The result was nothing you’d expect. CPU still works perfectly fine, just can’t overclock the damn thing on 4.5 GHz… which sucks because I really want to get a 1080, but the clock speeds would hold me back from doing so. Ugh…

  17. I want to get with the hype of Ryzen as well… but after the disappointment of the R9 Fury, I kinda am second guessing myself. But hopefully they release these chips before I get my income taxes lol. That way, we can see some benchmarks!
