Just got a brand new 7700K running at stock on a Gigabyte GA-H270N-WIFI and the CPU temp is hitting 100 C when I start handbrake. CPU cooler is a Thermaltake rated for 95W TDP. Using Arctic Silver 5 paste. Have tried reseating the cooler and cleaning/reapplying the thermal paste, no difference. At idle, CPU is ~33C. Jumps back up to 100C shortly after starting a handbrake encode. Doesn't matter if case is open, room temp is 74F.

What am I missing here?

if everything it's at stock check with CPU-Z the voltage supplied to the CPU under load.. sometimes some motherboards just doesn't regulate properly the voltage and even at stock settings apply a insane amount of it, also some motherboards have features that override stock turbo speeds and automatically apply a small overclock, so worth to check.

also I agree with Ocellaris that the CPU cooler you are using isn't anything remotely good enough to cool a 7700K.. but also you shouldn't be getting 100C in Handbrake at stock settings.
 
You can also disable MCE(May be called multi core enhancement or similar) in bios, I bet you run the CPU auto overclocked as well with relatively high voltage.

That will be a million times better than the cooler you have, but there are better options in the same price range. What are the dimensions for clearance in the case? If that is all that will fit, fine, but lots of other options if you have a bit more room to work with.

Such as this or this.

The case is a Silverstone ML09, the most it can handle on cooler height is 70mm.

Use one of the suggested heatpipe coolers and make sure you get the two additional 80mm fans supported in that case and set them up to exhaust out the side.
 
I'm using a Noctua NH-L9x65 for my i7-7700. It works but this i7-7700 runs ~10 degrees hotter than both my i7-6700. I think Kaby lake heats up quickly and is very slow to shed heat, it will do that with ANY heatsink.

The AXP-100H would fit in that. It is also possible that one of the slim AIO coolers would fit.

Personally I woudn;t use anything less than an AIO cooler for a 7700K even at stock clocks. THey are a HOT chip.

THere are many tower coolers that are good too. So yeah big ass tower or AIO and you should be good.

He is limited to 70mm due to case limits, so tower coolers are out. So are many AIO, but as I said above, I would be willing to bet some of the slimmer AIO with fittings that rotate to the side would probably fit. Exhausting all that heat outside the case should help as well with the AIO with such a crammed case.
 
soupcxan can you show a CPU-Z while running your encode. A few tweaks in BIOS to avoid the auto overclocking and high voltage associated can perhaps fix your issue.

I’m traveling right now but will when I get home. Also will try the new coolers I ordered.

Yes true. If your recirculating its just gonna get hotter and hotter. Also the OP may have not had a good mating or put too much goop.

Look at the cooler he was using, even in a perfect situation, it would over heat.
 
kaby lake runs incredibly hot with AVX loads like handbrake. even delidded and under custom loop watercooling 5 ghz overclocked kaby cpu's will hit 60-70+ C!

New CPUs make very little heat, my i7-7700 ITX idles at 15W at the wall. Today's technologies are more efficient at any workload compared to CPUs from 10+ yrs ago. The i7-7700 is no exception, problem is the laws of thermodynamics, it's a smaller die = smaller surface for heat transfer + the IHS is trapping heat due to the crappy TIM.

a stock one would idle cool, a stock 7700k idle's perfectly cool. theres a big difference between normal use loads and AVX loads on intel cpus in not just thermals but power consumption.
 
How quickly does the cpu get to 100C? If it's within a few seconds this might be indicative of a bad factory paste job between the core and IHS and a relid might be in order. You should also check the voltage under load as previously suggested.

You might be able to undervolt a bit if you don't plan on overclocking. If for some reason the new coolers you ordered don't work there is also the option of a higher cfm fan.
 
it's hitting 100C under the hood because Intel decided to use less thermal paste than they should have (just another profit increasing choice they made, I'm supposing) so now you get to buy a Rockit de-lid tool for $40 + Coollaboratory Liquid Pro glue for $14 + re-lid kit for $8 = $62 then add in cost for shipping so I'll say $70 total. So you're $340 Intel i7 7700k that cost you $340 new now cost you $410 and the warranty is void once you pop the lid off ...

just more "happy gaming" brought to you by the folks at Intel

So true but hey .... he'll get far better thermals. Its a shame because its not a justfied approach to what intel should have done right.

Im buying a 8700k as soon as reviews are out tomorrow and the temps look ok. I dont want a flame thrower for a cpu. Even if Im going to adapt my XSPC raystorm to cool it.
 
temps should be fine so long as reviewers are not throwing AVX loads at it to test temps (see newer prime 95 versions)

AVX is what causes the crazy high temp spikes and trust me those exist just the same if you have delidded and watercooled the cpus it just instead of 85-95C you see 65-75C for every other normal use case temps are 10-15C lower if not a bit more in my experience. i should know pretty well at this point as well sense in the past year i have owned and delidded a 6700k, 7600k and 7700k they all behaved the same way with temps

It's just a massive unneeded step for the enthusiast tho to have to delid for decent temps. The 7700k was the worst offender out all of them tho, will see how that turns out in the official reviews tho.
 
Some of you are overthinking this. The cooler the OP ordered is a simple aluminum block with barely any fins. A better cooler and some case airflow will keep the temps down into a reasonable area.

i ran my 6700k without delid for a long time overclocked without issue. the temps look scary as hell when you run unrealistic avx loads on them but fact is they work perfectly fine doing it. all that being said for sure without a doubt if someone wants to seriously daily overclock an 8700k to its potential and keep temps in control nicely your likely going to need a really good AIO or a custom loop and likewise it will be well worth the investment to delid it and put some LM past on the die to help with the heat transfer.

unlike AMD cpus intel cpus don't actually seem to care about excessive temps when it comes to stability for whatever design and manufacturing reasons, needless to say though nobody in their right mind is going to be comfortable running a daily OC that reaches above 75-80C under load so I can see that side of the coin as well for sure.

They also measure temperature completely differently. AMD doesn't even have a core temperature reading. They throttle at what, 75C?

You have to add your labor to that, unless you consider your time to be worthless. In the end it becomes a $1000 cpu without warranty. For most of us delidding and plumbing are out of the question. AMD CPUs are soldered, so you have a better option.

Here's a shot of CPU-Z with handbrake running an encode.

I just put a Cryorig C7 on and it didn't help at all.

Am I crazy for thinking an intel chip should be able to run at stock speed and not hit 100C?

It's worse than mine, I'd return it to Intel.

I already told you (above in post #10) that it will overheat with ANY heatsink.
 
Those voltages are high. Drop the vcore to 1.23 and check for stability. It should be ok, some people can go lower if you want to try, but that should be a safe zone. Also for AVX tasks like handbrake you can do a negative AVX offset in the BIOS which will also help.

Also if you don't already have them, put two exhaust fans on that case, assuming there's no video card in the way. Get good PWM ones and you can put them on the same connection as the CPU so they spin up and down according to the CPU load, which will keep things quiet when it needs to be.

That is idle, that is also the 65W 7700, not the 91W 7700k and not under AVX loads, which can get very hot. Also, it has been tested that the TIM used on the Intel chips is actually very high quality.
 
I'm also experiencing this with a water cooling setup - going to try some of the suggestions here and see if I can cool the darn CPU down a bit!
 
Try undervolting the CPU, you can usually lower it quite a bit which will help a lot with heat. Using AVX offset should allow you to run lower vcore as well.
 
I'd be curious what temps you get if you leave the cover off of the case. Maybe you aren't getting decent airflow
