17R4 / 7820HK / 1080GTX temperature issue

Hi Guys,

As a replacement of my 17R4 6820HK that has been finally damaged by an onsite engineer, Dell sent me 2 weeks ago a brand new 17R4 with 7820HQ with UHD GSync screen.

While this is really a great config, i'm disappointed to find out that my previous temperature problem has been transferred into the new generation

in OC3, the temperature reach 100° and throttle very quickly, i've tried to undervolt, but machine simply crash if i go under -30mv in XTU

i had conversation with both Technical Support and AW marketing team, but their final approach on this is machine is working as designed...

i have seen multiple post on repaste, heatsink bending, liquid metal but before going that road i'd like to ask Dell to deliver parts that may be usefull in that operation.

Any part number you recommend me to change while in that situation ?

Any other advise ?

Thanks

 

From what I understand the 1080 based system is hot running to begin with and I assume most that get these systems either deal with it or use Liquid Metal to increase the heat displacement efficiency.

 

You are need reparte this laptop with, LM. This workaround solution.

 

only thing you can do is repaste with conduconaut and hope that the heatpipes stop working in reverse. Right now the heatpipes use the CPU as the heatsink for the GPU.

 

Man these systems were not designed to run OC level 3

It's a 7820HK your have not HQ. (That's a good thing)

Don't use the Dell stock OC profiles they are **** and make life very difficult to diagnose issues by clocking each core and voltages differently.

That's possibly normal for your CPU to crash with an undervolt at that clock frequency using a stock Dell profile, if you want to OC you'll need a proper profile and proper cooling.

Every gaming laptop from any manufacturer will struggle to OC (especially to 4.3GHz) without a repaste and some proper heatsink balancing

Yep either don't overclock or repaste. You don't have to use LM though, it's safer to use kyronaut (although you probably won't get 4.3GHz, maybe 4 or 4.1)

No that's rubbish, as has been discussed before it cannot transfer heat from heatsink to CPU. The heatsink is always cooler (especially under CPU load!)

Because the Dell stock profiles are terrible. These systems with perfect cooling can handle 4.6GHz on all 4 cores simultaneously (Dell stock OC profiles have lower than this on other cores). most with LM can handle 4.3GHz no problem.

You can multi quote you know lol

 

Good thing is that all your temps are within 4*C of each other. Means you got yourself a good heatsink and you don’t have the big differential issues a lot of other have had in the past. Either crack it open and repaste/repad it if you plan on running an OC, or just run stock clocks and game on. The gains from an OC are negligible for the games I play, yet I still chose to repaste. Repasting with cryonaut dropped my temps across the board by 15*C.

Not on the phone and sorry
