    Hey guys,

    Just built an i7-7700K system with an Asus Z270-A Prime motherboard and Kraken X62 cooler. Using this guide I managed to get to 4.8ghz with a vcore of 1.27. As i'm fairly new to this I didn't push it any further than that. Using Realbench my temps max out at around 65C which i'm happy with. The issue i'm having is the CPU temps when only at 30-50% load. It gets to 60C a little too easily which results in the Kraken getting rather loud. I know I can tune the fan curve to avoid this - but are those temps normal?

    Great work on the overclock. Cant complain about that at all.

    Yes, the spikes are normal on a non-delid cpu. When delid is less of a spike, but still happens. You can change your fan profile to ramp after the normal spikes if it annoys you enough.

    I have fiddled around with my machine now and the gigabyte bios seemed to by smashing the voltage up on this chip causing it to get 80+ temps. With a lower VCORE setting of around 1.23 I can sit on 4.75GHZ with 101x 47.
    I am happy with this outcome and I haven't seen the temps hit past 80 now in realbench and other tests.

    Just delidded and nearly died of relief when it booted. Also 25 degrees cooler, not too shabby!

    make such a difference

    im on my 3rd 7700K, and this one is by far the best.

    Currently

    7350K @ 5.0Ghz 1.38V 3200 C14 @ 3866 C12
    7600K @ 5.0Ghz 1.31V 3200 C16 @ 3200 C16
    7700K @ 5.0Ghz 1.30V 3200 C14 @ 3200 C14

    Time to see how the IMC's go with these 7600k and 7700k, they should be good, should be able to do 4000 c12 (poor little 7350k just couldnt do past 3866)

    So i just did a basic OC 5ghz @ 1.36v (plan on lowering it) and ram is just XMP. Apart from that i haven't touched anything. Should i bother Oc'ing cpu cache?

    What voltages of these should i adjust or should i leave them manual?

    only OC the cache if you intend to run benchmarks, for every day use and gaming sweet f all performance boost. Will also require more cpu volts to clock cache as well.

    just grabbed a 7700K and an Asus Z270 of some variety today (bundle at Scorptec), cooled with a Fractal Design water cooler, and didn't like how much the fans were spinning up all the time. Practiced delidding using an old Athlon64 I had in the drawer, then did it to the 7700K (with the razor blade method). Safe to say I shat bricks when turning the computer back on again, but it's fine, and a LOT cooler. Selected the 5G overclock option in the bios, and it Just Works.
    Then spent an hour on an online chat with microsoft trying to reactivate my w10 installation, and they ended up issuing a new product key.

    great, what paste did you use under the IHS?

    Have you resealed the IHS or just loose?

    delid is a must on kaby (had 3x7700k, a 7600K and 7350K) and they ALL benefit from delid, not just in temps, but lower volts for same overclock as well.

    Used some arctic silver 5 I had lying around. Didn't glue it back down, just holding it in place with the socket.

    Use thermal grizzly conductonaut/liquid ultra for heaps better temps. The As5 will dry out pretty quickly.

    ye old faithful, thats the paste i use between my IHS and blocks.

    i use Thermal Grizzly Conductanaut under the ihs. But being a liquid metal, its a little more involved in using under the IHS then a tradtional thermal paste. Plenty of videos around if you want to try it out.

    Getting to 5100 on my new 7700K was trivial with stock settings just changing ratio - 5200 crashed and I don't want to run it at it's limits so I've left at defaults :)

    is using a razor an acceptable way of removing the heatspreader?
    also what adhesive do you guys recommend when re-lidding?

    Razer will work, but not the safest method out there.

    ordinary bathroom silicon is what my cpu's are resealed with!
