Warning: Some i7-6820HKs and i7-6700HQ have Uneven Core Temps due to Uneven Heatsink

What about 100C with only 40.69W?

Spoiler: With following beautiful blue...

bleh, seriously considering cancelling my order.
Sales rep: "if they were really serios issues then dell would have stopped selling Alienware model forever"
Me: "you don't think a +20c differencial temperature on certain CPU cores is serious?"
Sales rep: "but 5000+ positive reviews cant be ignored with 21 negative reviewsd"

 

And how many of those 5000+ positive reviews know about the problem? And how many have monitored the processors behavior(throttling - high temp)? None? So there is only a few aka 21 +- owners who have experienced this nasty design flaws with following high temp and fully throttling? Oh'well We have to see

 

Lapping only works on heatsinks that are already flat.

 

Guys,

when I get my a15 r3 I will run tests on the cores/temperatures. If they are not to my liking I may try to repaste it and tighten the screw mentioned. I have done neither of these things before.

• Will it void my warranty?
• Is these tasks difficult?
• What brand of thermal paste would you recommend?
• Any other tips?

 

Actually the max I can manage is around 30w before temps go fubar


The unit is getting replaced by Dell so I have to hold off repasting for now

 

I know you can manage decent temperature with lapping, Liquid metal and fixing the pressure on Die on most part of notebooks.

But I imagine a lot of people can't or don't want messing with this themselves. And relying on the outsourced Dell tech fixing this mess is another matter

 

maybe dell should outsource to me for a special thermal management service lol

 

If only you lived near the Pittsburgh area ;_;

seems like they are doing something... i am looking forward for what it will be

 

Everyone -- Frank Azor will be addressing the heatsink issue today or tomorrow: https://twitter.com/AzorFrank/status/797136727517396995

 

great, just in time not to impact my alienware currently somewhere being shipped from asia to the states.

 

Is this issue present in the AW17r4?

 

I also accept mail in services

 

Tempting but I'm not a big fan of mailing sensitive pieces of equipment.

 

mail it through fedex and insure it

Perhaps just me, but it doesn't seem to me like that'll be good enough. Having a single weak arm on the heatsink near the top side of the CPU is a flawed design, and unless the heatsink design is changes I can't see it maintaining enough pressure.

 

Now I wonder whether the laptop I ordered earlier this week has the new manufacturing process.... hm..


Oh, what do you guys think about the gtx1080? Everything I've read points to the CPU being the weak part in the thermal design rather than the gpu. Likely wouldn't be much worse than the 1070 in terms of heat?

 

As long as AW tests for the CPU core temperature differential in QA as an indicator that the paste / heat spreader pressure isn't evenly applied, this awareness should be enough to catch the faulty assemblies before they make it out the door to a customer.

We should see the problems reduce greatly, and if we don't it will be time to get AW's attention again

 

More from AW_Umar: https://twitter.com/aw_umar/status/797211086940409857

Essentially a repeat of the idea that 95C average temperatures are "normal" and there's nothing wrong with that.

 

Technically true, when pushing the limits, but you wouldn't want to live in that range day to day, all the time.

It's not just bad for the CPU / paste, it's bad for the rest of the motherboard parts and surrounding components. That high constant heat load is going to stress the whole system.

The good news is if AW tune the pressure correctly and get even CPU core temperatures, I would expect the overall temperature to drop well below 90c.

If there are any of you with +-5c essentially even core temperatures and are still hitting higher than 90c, please let us know.

 

Probably newer revision of the heatsink retention bracket, with shorter screw pegs.


Problem is that the retention bracket cannot be removed without a heat gun.

 

Welp, there it is. From AW Umar:

https://www.reddit.com/r/Alienware/comments/5chgtc/an_update_to_alienware_1517_initial_reactions/

95 degrees is the new normal, fam.

 

@Papusan @Mr. Fox

welp

 

ayyy lmao

 

Best cooling is above 90 degrees doe....

This is a joke... for real. And i cant believe that only 1% complaining about Heat issues

 

New super mega ultra cool design for super iper heavy tasks = 95c average is normal

Precisely. The responses from them are a joke with saying that 90C's are okay. It's just plain madness.

Are they blind to see what these things can run at if it had a proper contact and with good thermal paste? A 30C drop in temps is pretty significant and what a slap in the face it must be seeing my 100% CPU loads at 40x running in the 60C's lol...

To even justify that with some lame responses only shows the level of integrity (some) of these people have toward caring for their customers.

I'm am grateful for those who are taking measures to rectify this matter though so kudos to them. I have much respect for them at Dell and you know who you are if you are reading this.

At least they are listening and taking action. This is a huge plus!

 

Honestly I'm thankful there's people like you who to spend all this time to show them what the hell is up.

 

don't worry about cooked heatsink causing bad temps, because your laptop will run fine on 99c because the cpu is rated tjunction is 100c /s

 

xD

btw if anyone thought i was being sarcastic i wasnt.

 

Maybe 95C processor temperature is acceptable for their AW desktops as well? A normal ****y Dell thermal paste will pump out very fast with this *low* average processor temperature. Even high quality thermal paste will suffer from this high temp. No problems... Just call Dell support after a short time and they will push out their outsourced tech who will apply new Dell thermal paste for you

 

***11 HOUR OCCT RUN on the 15R3***

EXTREME TEST! -40C Drop in 'Current' Temps!

Look at the temps! Max and Average.

• Liquid Metal Magic: Grizzly Conductonaut
• Thermal Pad Replacement: Fujipoly 14.0w m/k
• Realignment of the top tension screw on the CPU side of the heat sink. Click here.
  
• Lapped Heat Sink.
• Polished Everything Squeaky Clean.
• -40C Drop in 'Current Temps'! (88C - 48C = 40C)

Notice the even current Temps?

• 48C
• 47C
• 47C
• 46C

========================================================================

6820HK Stress Test. PASS.


-

15R3 with STOCK TOOTHPASTE and STOCK CLOCKS. FAIL.


Thanks to @Mobius 1, @DeeX, @zergslayer69, @hmscott and everyone else that is contributing in providing valuable data!

========================================================================

 

That is amazing....what a difference.

 

Woah. That is some drastic difference right there. Think a 4700H/MQ could benefit from these cooling modifications?

 

Absolutely. Just take your time and clean everything very well. The results will be worth taking your time doing it.

 

I really want to do this to my AW15R3. I am trying to source these products either online or local (Ottawa, Canada). Would 1.0 gram of Grizzly Conductonaut be enough for both CPU and GPU? As for thermal pads, I can't seem to find the Fujipoly ... perhaps provide a link? Thanks and much appreciation for all you've done thus far.

 

if u live inside europe, try alphacool... they offer the same product but are easier to get in europe (at least for me)

 

Yes, 1.0gram will be enough for both the cpu and gpu. As for the thermal pads pretty much anything will be better than the stock recycled toilet paper.

Good luck! Let us know if you have any questions.

Hey! So... good news and bad news...

I saw there was a 1.0.6 bios update on Dell's website so I tried it, what did I have to lose? Right away I noticed it was running cooler and the fans were quieter, cool I said.. I gamed a bit and noticed the cores were staying about the same now!!!! I was happy..

Then after some more gaming, I have this... crap, now ALL cores overheat LOL



I might be onto something now, because I am still going to repaste/repad my heatsink... maybe now it will all be uniformly lower.. hmm, this is getting more interesting the more I tinker with it.

 

Perhaps something like this ↓↓↓ can be the best solution to your heat problem? And with a better thermal paste, maybe put the refrigerator at half or 1/3 of the power? 101C is damn hot

 

Lol, I actually have a bar fridge right next to my desk, maybe I can move it in there

But seriously, I am going to buff the heatsink, repaste and repad and hopefully be all good! Thanks iUnlock!

 

You should be golden.

 

The BIOS fix ie....band-aid...probably just tricked the sensors to give the illusion of cooler temps haha! I wouldn't put it beneath them LOL.

 

You know whats funny... I ran OCCT for a minute and it shows the 2 cores going hot again lol.. very weird. I am still going to lap the cpu and all that, I am still pretty sure its just bad paste!

 

Oh it's definitely the toothpaste along with the unevenness of the contact points. Looking forward to your results!

 

Thanks.. I was going to do it earlier but I am still having a hard time finding the pads.. Also, do you think I should attempt the liquid metal type stuff you used or stick with a regular paste now?

 

I did the bending trick just now. It seemed as soon as I screwed it down it went back to normal. I ran firestrike the cores were about 7 off max. The max temps for CPU was 84 but I watched it the whole time and it stayed 68-72 for the most part and the fans were whisper quiet. The gpu maxed at 66 but stayed around 60 the whole time. 6700 and 1070. CPU was at -165mv and the gpu was wasn't at +200 on clock and + 400 on mem.
