Does 8700K run that hot at Intel's rated stock speeds?



And that is in an environment where the i7 7700k runs at just 71*C, I've never seen it running below 81*C without delidding.

If you wanna improve the temp of a cpu that turns out to run hotter than you expected, you have to delid it, but would you have still bought it knowing that it would run hot ?
I also wonder about the effect delidding in longevity. Will liquid metal and the paste that you use to re-lid the cpu wear out after a while and you have to delid it again to fix that ? I'm not afraid of voiding warranty but having to maintain cpu after delidding is not something I have time for.
Reality is most of us pretty much know that a delid is necessary these days if you want to get the most out of your CPU and get decent temps, each generation is getting hotter and hotter i dont see that ending anytime soon. Delid will void your Intel warranty but if you buy a speed binned CPU from Silicon lottery or caseking you get a warranty from them instead. In all the time that I have had a delided CPU I have never had to replace the liquid ultra that was originally applied, according to Silicon lottery they have never had to replace the liquid ultra on any of their customers CPU's smile.gif What I would like to see Intel do is cover deliding with their performance tuning plan warranty, as a good public relation gesture to at least appease some of its customers.

Btw, I'm surprised that this thread discusses everything about i7 8700k but the fact that it runs dangerously hot (92*C in Linus' video, with the corsair H115i under df speed). The chip is not only on par with Ryzen 7 in productivity performance but also the best for gaming, best of both worlds and that's expected. But how dare anyone build a system with that chip knowing it runs that hot ? That issue alone is enough to put everything else in shadow.
My x58 rig is dying, I skipped skylake and kabylake waiting for cofee lake, i don't like ryzen 7's gaming performance and its problem with high speed ram. Now i'm lost.

What are you saying here? Coffee Lake is cooler at stock speeds and OC on average betetr than Kaby Lake and thats what all the bars are saying too. Thats why no one complains about it. The rerason is rumored to be a better thermal paste.

Doesn't liquid metal harden around a six month period? If they are making a new IHS I don't get why they don't solder. Way easier and cheaper than making a silver IHS. Just use indium foil and melt it on with a heat gun.

No it stays liquid

It hardens out for some, because it's reacting with something else
And that something is usually copper

If the surfaces are Nickel plated then it stays liquid
The IHS is plated, and the die of the CPU doesn't react with it either

Now
Does silver mean better temps?
Probably not really

Using without any IHS gives usually around 4 degrees better temps compared to a delid
There are waterblocks made out of silver, those usually improve temps by low single digit values
The handful of test I remember, of which there aren't many at all, showed something like 3 degrees

Relatively far away from the 10 degrees caseking is claiming
Ehh
Marketing speak

Why don't they solder?
No one has done such a thing I think
But using the LM and glueing it back together people have experience with
So much so that they give out a replacement guarantee on it

Besides
If you're using a heat gun you could damage the CPU, or warp the IHS

It's not something that should be done and masse by hand (well relativly)

It's something that needs to be done by the manufacturer having the right tools at hand

But Intel never stated why they don't use solder any more
Maybe it does warp the IHS a bit
Having to Mapp an IHS was not that uncommon

Or maybe it is like we all think and it's just cheaper this way

Or it's the 14++ process which is supposed to deliver better frequency with lower voltages

And still
No paste can be as good as solder
Only LM is as good, most likely because it's metal as well, just like solder biggrin.gif

Also
As long as you run things at the value Intel wants you to, means 4.3 Ghz with all cores at 100%, then it will not run hotter

What I would like to see is either returning to solder
Or
Sell the K line without gluing the IHS on

At least then after market cooling companies would have a big enough audience of customers to make mounting options available using no IHS

The problem is, Intel will not cover warranty once the IHS is off, it is extremely selfish on their part and I wish they will lose more shares for their arrogant decision.


Zen 2 please crush them!

To go along with you're 8700k

the 3600 is enough considering the uptick in price
On top of that DDR4 prices are inflated at the moment

And
Intel does not benefit as much from better RAM speed as Ryzen does
3600 is quite enough

If you want, you could still manually fine tune the speed as well
