Hello folks,

Long time no post!

I have been enjoying my PC (currently I5-3570), issue free so haven't had to post for a while. Some poor performance in games has prompted me to make an upgrade.

I just indulged in the following:

Intel Core i7-9700K 3.6GHz

Asus ROG Strix Z390-F Intel Z390

Kingston HyperX Predator 16GB (2x8GB) DDR4 PC4-25600C16 3200MHz

Corsair Hydro Series H100x

Samsung 970 EVO Polaris 250GB

My question is this:

Should i de-lid and polish / re-lid my CPU to reduce temps? (Video Link Explaining)

I am not too bothered about OC'ing to 7 but 5 would be nice. Fingers crossed the silicon lottery has been merciful!

Any info from those brave / daft enough to try this would be great!

Much obliged...

See how it performs and OC unmodded before you crack it open. :cool:

If it does everything you want then theres no need to pull it apart just yet. Perhaps you could do that in the future to get some more performance out of it if needed as it ages.
 
I have delidded my 7700k and currently running @5Ghz with no issues. Barely goes above 60c using the liquid metal.

Although i have done this, and used the the correct delid tool i still researched the hell out of the topic before i pulled the trigger as there is a lot that can go wrong, voiding your warranty for starters.

For me this was a must as the 7700k chips were notorious for sub standard thermal paste being used on the ihs. Not sure if this is still the case for the newer generation.
 
As IT Troll and others have stated, I would see how it goes for a month or so as I suspect delidding will have a greater effect on your perceptions rather than anything really tangible.
 
Thanks for the input folks, greatly appreciated!

I am notoriously lazy when it comes to computers - once it is built, it stays built - hence why I was investigating this process before initial install.

Your input has convinced me to assemble as is, fingers crossed for a good chip :D

Thanks again.

You have to reapply liquid metal from time to time I believe.
 
That further reinforces my decision to leave it be! Once it is installed and the cooler is on, I will leave it alone (unless something is wrong ofc).

I am excited to receive my bits now!

P.S. I know you guys are OCUK regulars, however I feel I should stress that the customer service received from the team has been awesome. I had one issue that was fundamentally my fault; it was rectified quickly and without fuss (thanks RL). Loyalty breeds loyalty - thank you OCUK, you rock!
 
You can get it down what 5 degrees with liquid metal vs the solder but that’s about it.

And is say running your cpu at 80 vs even 85 or 85 instead of 90 worth the risk of delidding a soldered cpu? No not really.

Or vs say just upgrading your cooler?

It would run 90c for the duration of its life without any issues.

Also polishing is never a good idea as you take the top protective layer off and then you could end up with liquid metal defusing into the silicon over time.

I’d say just leave it be and enjoy :).
 
@tyler_jrb , good point about the cooler. I have a single rad in my current setup. Hopefully the double on the H100 will keep the chip nice and chilled, though the TIM is a fundamental part of the cooling process, so rad-size benefits are limited if the TIM is poop.

No shipping email yet, was really hoping to assemble it tomorrow and post running temps.

Ahhh well, i can always get some Haribo from the shop instead :cool:

Hell of a setup BTW Tyler :eek:

Thanks :). Not as good as some on here but does a good enough job for me :D

With it being solder, should run plenty cool enough. Not like the toothpaste on the 8700k etc :p which gave 20c+ from a delid.
 
I'm not sure how it is for the 9700k, but with the 9900k it appears that intel is selling any silicon they can as a 9900k.
This means there is huge variance between 9900k cpus in the silicon lottery. There are reports of cpus doing 5GHz allcore and higher with super low vcore while others simply can't do 5GHz allcore without pushing vcore so high that you reach thermal limits.

If the 9700k series is treated the same and the silicon you get is on the lower end, delidding will only get you a minor decrease in temps. You would be better off selling it and buying another to see if you get a better performer than delidding.

The benefits of delidding the 9 series are much lower than the 7 or 8 series. Silicon quality matters much more this time around.

I hope you get a decent chip so none of this is relevant.
 
Howdy! Just thought I would post a little feedback. Crazy ASUS on board AI overclock gadget got the CPU to 5.3G and the system remained stable. Not sure of voltage but temps were high 50s during POE 4k gameplay (Summoner build - so lots going on).

My only observation is the AIO is quite noisy at times. It may just be that it is pointing upwards out of case which is on floor, so the sound is directed towards me, rather than out the back like my previous setup (single AIO rad).

Thanks for the advice, very glad I followed it!
