#Legion 7 Slim Amd Gen8 4060 high gpu temp?

Hi, I'm having hot GPU temps on my Legion 7 Slim Amd Gen8 with 4060 card.
The back end of the laptop is raised 5cm from the table.
On Steam's "The Complex Found Footage", for instance, In Performance mode,
GPU temp averages 82C while the hot spot averages 102C (106C peak) and 103Watts. At this temps the metal chassis above the F1-F8 keys is very hot to the touch.
CPU is fine at 65C.
Is this normal? Any tips for reducing temps?
Thank you!

Model: Legion S7 16APH8 - Type 82Y4
Issue: Hot GPU temps
I noticed hot temps recently as I only recently started playing games such as 'The Complex Found Footage', DCS World, X-Plane 12.
Using 551.86 Nvidia drivers and latest firmware from Lenovo. My laptop is generally lean without bloatware. I also disabled 'performance boost mode' under power plans.

I'm generally happy with the laptop except GPU hot spot of 106C appears excessive, or am I wrong?
Thanks for your help

yes all clean, it's a 4 months old laptop, never opened. Room temp is roughly 19C

I guess so, I hardly play games on it, I just started

#

Well if you say it’s clean then it’s 1 of 2 things. Bad paste job on GPU or poor heatsink mount.

It's normally ok because I hardly use the GPU, I use it plugged and on 'balanced', and when the bottom is raised, the laptop tends to be cool enough. When the keyboard/top of the chassis gets hot I turn on performance to cool it down for a while. But I haven't gamed much

#

Also, the GPU temp was around 83-85C, but I only discovered about this other temp called hot spot today.

#

What temps should I see?

dusty dome
#

I would expect mid 70s at most with what cpu temp you’re seeing. A good paste job will keep the hotspot at 10c or less above core

#

Anyway, not really anything to do besides trying to repaste

bitter chasm
#

ok thanks, I suppose I should contact lenovo support

#

what did you mean by poor heatsink mount, just how it's mounted, or defective?

dusty dome
#

Could be either

bitter chasm
#

wouldn't I void warranty if I was to repaste it? can I repaste the GPU separately from the CPU?

dusty dome
#

Most regions no it does not void warranty. No, it’s a shared heatsink. You repaste both if you remove the heatsink

bitter chasm
#

Ok. I'm based in London and should have on-site assistance, couldn't I request a heatsink replacement?

#

I'm looking into it. Are you saying that the GPU temps are fine, and the issue is with the hot spot point right?

so basically just buy the 7950 pads, clean the gpu/cpu die and apply, right?

dusty dome
# bitter chasm are there other chips/places that would need repasting after removing the heatsi...

The particular machine uses thermal putty for VRM and vram. You should have all thermal pads on those components, but there may be putty.
Heatsink pic pinned in #legion-7slim shows all pads. You should also be able to confirm by looking up pictures of a heatsink replacement on Lenovo support for your machine. Go to Lenovo support, get to the page for your machine, go to parts and find heatsink/fans. Pics should confirm.

it seems very similar to the one pinned.

#

it does have a black frame not present in the pinned image. Also I guess the thin black squares are the TPM pads that just need plastic peeled before applying as a new thermal pad right?

#

tell me if my thinking is wrong: repaste option using original heatsink: I should be able to retain the original pink pads without replacing them, just clean the gpu/cpu paste and apply the two PTM7950 pads and voila'.

#

BTW Tunaman, thanks for this crash course in repasting. I'm still not 100% sure about going ahead 🙂

dusty dome
#

Yes. So you should be fine if you want to repaste with PTM. All pads. They should be ok when you remove the heatsink.

bitter chasm
#

ok thanks. Honestly I thought you would come back with 83C GPU Temp? that's normal 🙂

dusty dome
#

Feel try to try and pursue Lenovo for a heatsink

#

On this Unreal game in specific, GPU temp and GPU hotspot show a 18-20C increase, pushing hotspot above 100.
Other games are in the 70-80 range actually.

#

So far it is only one game that pushes hot-spot so high. Can you recommend a benchmark or game I can run so I can compare temps against other users with this machine/gpu specifically?

thx for your support mate!
