Well used CPUID HWMonitor for the temps and the below is what they hit within 5 seconds or less of starting the stress test in RealBench. Yeah i have the latest bios on the GA-Z270X Gaming 7 the F5 version i believe it is - only updated it yesterday.

Sadly dont have an alternative CPU cooler for the 1151 Motherboard.

Yep, that's crazy. 100 degrees on one of the cores at stock is bonkers.

I'm thinking your cooler is faulty. 

Are you sure you applied the TIM correctly and removed any cellophane coverings that sometimes cover the base?

Do try CoreTemp or RealTemp though, just in case Hardware Monitor is reading incorrectly.

Don't go mad, a mild test, so as not to generate more heat than you need to.

 

Yeah I have taken it off a few times (4+ from frustration) and cleaned it and resat it with TIM and checked all connections. Might very well be the AIO I guess. Have been building PC's since 286 days and never had an issue like this. Wish there was someway to test the AIO though.

Thanks for all the advise Martin.

 

Might just buy a cheapish air cooler and see how that goes as a test.

Yep, I have lots of spare components I use for fault finding. That would be my course of action. It's about eliminating variables. Process of elimination.

Personally I'm not a fan of AIO's, too many moving parts that can fail and leaks of course.

You should be able to grab an air cooler pretty cheap. Preferably one that there's reviews of with your CPU, that way you can compare temps.

The other choice of course is to contact NZXT and tell them what's happened. They will no doubt suggest a few things, and may well know from your symptoms that it's a faulty cooler issue. Why not do that first, as I say, they may well be aware of the issue with their coolers.

Well decided to give the whole cooler 1 more go. Disconnected the cooler and took out the standoffs and took the backplate out to check everything. Screwed the standoffs in to the backplate on my desk and noticed 2 of them were not quite going flush when i tightened them up by hand whereas the other 2 went flush with the blackplate. Probably a mm off. So I put it all back together again and used pliers to tighten up those 2 standoffs till they were flush. Applied new TIM and set up cooler. Now at 100% on stress test getting around 70c!

Much better.

Although if that's at stock frequency and 100% fan RPM it's still not as low as I'd expected. Don't have Kaby, have Skylake, may well be typical of kaby at stock for all I know.

 

Whats the ambient temp where you are? That will nudge it up.

 

 

No that was at the 4.8Ghz when I ran it.

Temp was high 20's today. Pretty warm day for Autumn and this room is the warmest in the house as well. Direct sunlight on the windows

Good luck Kevin. I'm sure it will all go swimmingly.

Be sure to let us know how much the temp drops.

Well lidded its booting at 32C 5.0Gz

Started P3D causes it to crash every time, and Realbench stress test causes it to lock up almost instantly. 

Dropped to 4.9 and it passed a 15min realbench stress test and loads P3D.

I'm guessing I got a bum chip...?

5 GHz at what voltage Kevin? Sounds like it needs a tad more volts I would have though. But what was the load temp, not the idle temp?

Not really, 4.9 is nothing to complain about, but as I say, at what temp under load and what voltage.

temp under load high 70s

voltage on auto ave 1.4

High 70's isn't too bad. Which cooler Kevin?

Is this an Asus board? If so you could try Five Way Optimisation, I've found it to closely approximates my manual overclock.

Fantastic Kaby Lake overclocking guide from Asus here...

 http://edgeup.asus.com/2017/01/31/kaby-lake-overclocking-guide/

Asus point out that 20% of CPU samples are stable at 5 GHz when running Handbrake/AVX workloads.

Asus recommend no higher than 1.40 Volts when running something like RealBench. And no higher than 1.35 Volts if running Something like Prime 95 that runs AVX.

i'll have a look at those links thx

Cooler is a very cheap AIO Coolermaster Seidon 120V v2 (£35)

Board is a Asus Maximus IX Hero, couldnt see any option for 5way optimisation anywhere, will look again

 

Cheers K

Oh right, you definitely need a high end cooler Kevin if you're shooting for 5 GHz or higher.

Five Way Optimisation is within Ai Suite. Your board does have it. See here...

https://www.asus.com/ROG-Republic-Of-Gamers/ROG-MAXIMUS-IX-HERO/

See the fifth bullet point down. 

There are quite a few options to select, so if you give it a go, I can let you know my settings.

 

Hi Kevin,

I also have just done an i7 7700K build with a IX Hero board so still early days for me.

I was able to hit 5.0 GHZ using the same tutorial martin linked. My lowest voltage without going into really tweaking & just using the settings in the guide is 1.322v. Was able to fly around in P3Dv3 with just about everything maxed but only flying the Carenado B58 Baron, Rainy weather scenario & it was high 30's frame rates with temps in low 60's.

I haven't been able to install the Ai Suite as it causes BSOD's for me & many others, so I suggest you do a system restore point before installing this software. 

 

AI suite installed ok didnt seem to be any problems.  5way only gave me 4.6Ghz so manually reset the BIOS to give me 4.9. Skim read the guide but I'm afraid most of it was gobbledegook to me. :(

 

Temps under load are usually high 70s, getting 50-60+fps in the VC in the NGX so cant complain.  Do you think the thermal headroom by delidding is worth doing?
