i7 7700k temp spikes. Is it a design flaw?

[somethingbrite]

Hi all.

Was about to pull the trigger on an i7 7700k for a new build then started finding threads about this Temperature spike issue. (and once you have found one suddenly you find many.)

Not had a chance to read all the way through all of them but working my way through the intel support forums now.

I have a few questions perhaps some of you may have info or an opinion on...

Are any of you i7 7700k users seeing this?

Is i7 7700k a flawed CPU?

Is the issue 100% negated by manual settings?
(I would be planning on a manual oc build anyway and annoying as knowing an element deep within the design is malfunctioning might be, if I don't ever see it I may not care so much)

Does this impact the 7600k too?

It looks like the glue is bit thicker than it should not allowing for better contract between core and IHS.

However in this day, why you want to buy a 7700K? Is overpriced and doesn't provide anything extra over the AMD offerings.
On the contrary, for £50 LESS you buy a R7 1700 (8c/16t), or for £110 LESS you buy a R5 1600X (6c/12t).

So you get the 1600X, and a B350 Tomahawk for the amount of money the 7700K has on it's own!
(or even better the 1600 and overclock it for £160 less than the 7700K).

Doesn't make sense

Like this? (Pic) its a well known issue with OCed KabyLake, Intel's response is, Overclocking voids the warranty.

The thing is the 7700K is an already Overclocked 6700K, not all chips are equal, the process has no doubt improved over the 6700K days to enable the higher clock rates but this is true less for some.

IMO, and i have said this before, Kabylake is a knee jerk reaction to Ryzen, up the voltage, the TDP and the Mhz up to 11... this IMO is why there are these issues.

Stop spouting rubbish and post the whole response from Intel.

Hello Everyone,


We appreciate the feedback you have provided, and your patience as we investigated this behavior. The reported behavior of the 7th Generation Intel® Core™ i7-7700K Processor, showing momentary temperature changes from the idle temperature, is normal while completing a task (like opening a browser or an application or a program).

In our internal investigation, we did not observe temperature variation outside of the expected behavior and recommended specifications. For processor specifications, please refer to the Intel® Core™ i7-7700K Processor Product Specifications.

Most motherboard manufacturers offer customizable fan speed control settings that may allow for smoother transition of fan revolutions per minute (rpm). Please consult your motherboard manufacturer’s manual or website for instructions on how to change default fan speed control settings.

We do not recommend running outside the processor specifications, such as by exceeding processor frequency or voltage specifications, or removing of the integrated heat spreader (sometimes called “de-lidding”). These actions will void the processor warranty.



Kindest Regards,

Ronald M.

You angling for a job at the Daily Mail

How is that ^^^^ different to anything i have said about Intel's response?

I hear ya. Am considering it too, would be nice to see the chipset/motherboard ecosystem mature a bit though. With the intel platform at least you know what you are getting because it's not cbanged much for a while.

Without this breaking down into an argument about what intel said and what they did not I would be interested to hear if this issue still exists even with fully manual overclock settings rather than just some motherboard auto settings and also if it is just limited to the 7700k or impacts the 7600k also?

Impacts all Kaby Lakes. Is the process is made. And ofc it affects everything, because if the IHS doesn't make perfect contact with the core, how you expect it to cool?
In addition is still using "cement" for TIM, and given then power draw of the Kabylakes is expected to overheat. Consider, an overclocked Kabylake drains more power on MT usage with it's 4 cores, than an overclocked Ryzen 8 core under exactly the same test & conditions.

To be fair it's (too thick sealant) affected all intel cpus for quite some time. My haswell chip had much better temps once delidded and I don't believe haswell was the first(?)

Not buying that. This issue be complicated by a poor cooling solution but that is not the cause. Things I've read so far indicate that this also occurs with delids. (However, I would be delidding anyway. - though not naked die cooling this time as my desire was to use a monoblock for this build to make simpler cooling tube lines in my build therefore I'll have less control over the direct CPU cooling...which of course means that rubbish spikes in cpu temps impact me more if my BIOS settings can't close that down.

Yes, it does still exist. My step father has a 7700k@stock which is cooled by a Noctua NH-D14. Voltage doesn't exceed 1.25V and yet temps will spike quickly into the 50s or 60s before quickly going back down to idle of about 28C when doing basic tasks such as opening basic programs or playing an undemanding game. When running BOINC temperatures are in the late 70s or early 80s (ambient temp is only about 18C).
