Gtx 1080 high temps over 80c

Hello guys I have recently upgraded my laptop from gtx 1070 to 1080, but now the 1080 is running hot up to 85-90c, is it because I am not using the correct thermal pads or what is my issue, I have used the same heatsink from the gtx 1070, any ideea of what thicknes the thermal pads have and where I can find a diagram for the GPU? I have pressed down on the thermal pads to make them thinner and it helped a bit they are almost 1mm or less I think, but the GPU still goes up to 85c is that normal temps for this GPU/laptop, thank you

 

This is probably your issue, as the 1080 has a much higher TDP than the 1070, 190W vs. 115W/125W. You want to use the dual vapor chamber heatsink for the 1080.

 

Liquid metal can help a lot too so long as you are careful.

 

Thank you, I have seen now that there are different heatsinks for this laptop to fit single cards or dual card, with or without vapour chambers, I just bought a single GPU heatsink for the 1080 with 6 heat pipes that split to both fans, hope it will help

 

I am running a GTX1080 in my P750TM1-G locked at 1,911Mhz with 11,384Mhz GDDR5X memory it runs 77C tops after hours and hours of non stop gaming.

You must undervolt the card, and run Kryonaut, or Liquid metal.

I run liquid metal, with K5 Pro thermal pad replacement. And I do have the GTX1080 model heatsink as well.

Replacing the thermal pads will help some. But GPU die contact is paramount.

 

You need K5 Pro! it is like a liquid thermal pad.

 

Can it be undervolted without an unlocked vbios? ( Which I don't have)
Also where the hell I can get an unlocked bios for my p870tm1-g

 

I also have liquid metal but I did not have to much faith in it so I will use mx5 plus copper shim and thermal pads

 

You adjust the clock curve that all models let you it's a bit different to sliders so worth reading up on how clock adjustments have changed.

 

You need to ditch the copper shim. Your thermal pads are probably to thick too. these MXM video cards require 0.5MM in certain areas. There is no diagram on how to properly install them either. That’s why I like K5 Pro liquid thermal pad. It just flattens down when you install the heatsink, so there is no guessing the pad thickness.

open up MSI after burner voltage graph. Click the box that is above 0.925MV and slide it up to 1,860Mhz then close out of the graph and click apply or the check box in MSI AB.

Your GPU temps will drop drastically. You can fine tune or lower voltage more later on.

 

I have not installed the new heatsink and copper shim(0.5mm) yet. I am waiting for it to arrive and I will let you guys know the results, as for undervolting with AB I have not tried that yet, I always used for OC Nvidia inspector but unles I have a custom vbios it won't let me change voltage, maybe Afterburner it will, so what is the safe undervolting values for this card?

 

You can change the voltage no matter the bios or laptop. If it has a GTX anything in
it you can undervolt it. Undervolting will give you the temps you so desire.

Download and install MSI afternurner, and you can undervolt that puppy right now and you will not even need a shim.

 

It's changing the clock curve so not sliders anymore. Two dimensional overclocking

 

i am sorry to say but i have just installed msi afterburner and i cannot move the voltage slider as it is grayed out, same with power limit and temp, like i said before i need an unlocked vbios

 

i really dont understand what you mean, sorry

 

Ctrl + f with MSI afterburner open.

 

Once you hit CTRL+F with MSI AB opened. You will see a graph.

Look at the bottom and select the box above 0.925V and move it up until it hits 1,860MHZ.

Then close the graph, and click apply! You only need to move one of these white boxes in the graph.

Your GTX1080 should have no problem running 1,860 solid at 0.925V.

You will probably drop 10-12C in temps.

This is a requirement in these laptops! You must use Ctrl+f modify the voltage curve. Then apply and save the profile.

You can fine tune it after and maybe drop off even more voltage.

My GtX1080 will run 0.893 at 1,873Mhz. And it runs about 69-71C full load.

I usually push for 1,911Mhz though which requires 0.925-0.931 and temps will hit 74-77C

 

thank you all for your help, problem solved, it was the heatsink, i have installed a proper gtx 1080 heatsink now and my temps on iddle are around 50c and on full load at 77c sometimes but rarely 80c, i will tweak it a bit with the oc curve as well and see how it goes

 

Watch a video on pascal GPU undervolting.

You are technically overclocking the card and finding the lowest voltage it’ll do it at. They get way to much voltage by default.

The undervolt will reduce temps more drastically than the proper cooler.

Here is how a GTX1080 heatsink should look for the Clevo models. It has the (3) heat pipes coming off it.

Here’s a picture of mine.

 

Thank you for the info, bought a proper 6 pipe heatsink and now is all good might give it a try with undervolting and see how it goes, at the moment time is limited as I am baby sitting two kids most of the time
