Ryzen 7 4800H overheating in games!

Hi, I recently got my new Laptop Lenovo Legion 5 (RTX2060, Ryzen 7 4800H, 16gb, Full hd, 1126 gb SSD). And everything is great except for the insane overheating in many games (especially in demanding games). The GPU is doing great

So these are the games I have tried yet:
Metro Exodus, Devil May Cry 5, Apex Legends, Injustice 2, Rainbow Six Siege, Frostpunk, Battlefront 2 ...

I know that the GPU is supposed to be heating less than the CPU, but why is the CPU so hot compared to my GPU??

The temperatures are sometimes as high as 95 degrees! When the GPU may be like 75... Is there something wrong with my CPU or is this normal?

I was also trying to undervolt it in the Ryzen Master but it is only working with the desktop CPUs. So is there a way to do so?

In Rainbow Six actually, my temperature even got as high as 100 degrees even though it is so much less demanding compared to games like Metro, Battlefront 2, and so on...

Thank you, Guys!

 

Rainbow Six uses AVX2 iirc and actually uses many threads so "much less demanding" is improper especially when many people technically play the game at half resolution unless that setting has changed since I played it.

You may want to consider repasting the laptop, generally good practice anyways as manufacturers cant seem to manage it at scale.

Next time you have a couple of soda's save the caps and use them to prop the laptop up so it can breathe more efficiently.

 

I play siege quite often and my 6700hq hits around 95-97 degrees C, its normal for siege to be super CPU bound. Do as Reciever says and repaste the laptop if the temps stay the same or get worse. Some laptops are just pasted bad out of the factory.

 

But that can't make such a big difference. I mean I watched dozens of reviews on youtube and they all said that my build will have around 80-85 degrees on the CPU, not 90-95! Is it for sure that my CPU is fine? (They didn't change the thermal paste on youtube on their laptops)

 

What fan profile are you using? I found that the balanced fan mode gives me the best thermal results while not annoying me with fan noise. I have run several benchmarks (linked in my signature) that show I can maximize performance without thermal issues. Only tweaking besides fan profile are GPU.

 

To add, I use MSI Afterburner to mod my Voltage-Frequency curve so that I can run 1650 mHz sustained without either thermal or power limit throttling.

 

Yes, it can.

I dont care what reviews say on youtube, I have no idea what laptops, cooling, or profiles they may be using. If your CPU wasnt "fine" it wouldnt POST. Lastly your laptop is not their laptop, they are separate units even if its the same model, more to the point, they likely got review samples which tend to get the extra mile that standard units are omitted from.

Troubleshooting with no baseline is not going to get you anywhere.

 

My temps on my Legion 5 are usually in the 70c-80c range when playing games and that when running on performance mode and using stock thermal paste. Your temps are pretty abnormal which tells me it could be a bad paste job or you're blocking the fans and vents. I would say try repasting the CPU and GPU but if you're still within the return window you can return it for another unit.

 

Yes but you are using 1660ti wich is a slightly different from my videocard. This may be the case as well...

 

In laptops the power envelope matters more often than the specific GPU die that is included, barring exceptions of course.

 

Its not as the RTX 2060 version uses the cooling system as the 1660ti version. Even with the 115w RTX 2060 you have it wouldnt overheat.

I watched videos on youtube of people playing games like Cyberpunk 2077 with the same specs as you and their temps remain stable. I still suggest if you're still within the return window you can return it for another unit or do a repaste.

 

I have the legion 5 with ryzen 7 and the rtx 2060 and my thermals are good. Normally between 70-80 C° (in summer will be high) in performance Mode with games like control,metro,mass efect Andrómeda.. Always have the laptop raised as in a base so that it takes air.

 

My Legion 5 Ryzen 7 4800H 1660ti Model goes to 100c in performance mode on Cinebench multicore benchmark.

 

And what's the 'score' @ 100C? Is it being thermally throttled by the high temps? If not, use a laptop stand/fan/cooling solution and enjoy the top performance possible that Lenovo allows, while giving you some heat relief.

CPUs are rated for 100C+ for a reason. If your model allows you to get to the maximum (safely), take advantage of it. And if the 'score' is as high as possible, then that means that the cooling design/system was properly thought out.

 

I'm scoring 11467 (multicore) on Cinebench... Doesn't appear to be thermal throttling.

 

Enjoy!

If the link below can be believed, your CB23 score is over 8% above average for your CPU.

See:
AMD Ryzen 7 4800H - Benchmark, Test and Specs (cpu-monkey.com)

And, your Tjunction max. is 105 °C, again, from the link above.

 

Cinebench is gonna make your CPU reach temps like that because its making your CPU run at 100% usage especially on Performance mode which makes your CPU use more wattage. My score is around 11200 which is great for a 4800H and your score is higher than mines so you got lucky in the silicon lottery lol. Anyways if you want lower the temps somewhat you can clean the fans and heatsink and maybe do a repaste of the CPU and GPU as well.

 

I wish you would have commented sooner, I ended up opening the case and repasting with MX-4 now I'm only scoring 10,300 in cinebench and I accidentally broke off a couple plastic clips from the back cover... Lol... Not sure what to do to get my CPU back to 11,000... I thought repasting was suppose to improve thermals by replacing the cheap paste Lenovo uses in the factory... Ugh....

 

Mx-4 thermal paste aint a good option for laptops. And you aren't the only one that experience this

 

What would you recommend?

 

Thermalright TFX, ICD, Phobya NanoGrease Extreme, Gelid GC-Extreme, Kryonaut Extreme, Coolermaster Master Gel. See if you can get the one in bolded text. I prefer Liquid metal (Grizzly Conductonaut) but if you go that route then read you up. Search Liquid metal in the forum. Put in @Papusan @Mr. Fox @Falkentyne in your search. Here is a link for you to start with http://forum.notebookreview.com/thr...nd-apply-traditional-and-liquid-metal.806840/

 

Thank you so much for your help!

 

I'll say do another repaste with a different brand. i might have to do the same eventually because lately when playing games my temps will spike as high to 97C but then drops back down in the 70C - 80Cs range and my GPU temps reached to the low 70Cs even with the overclock so i think its fine. I repasted with SYY-157 about 2 months ago and i probably didnt put enough on the CPU i guess, I dont wanna repaste the GPU too since the temps on it are fine.

 

Thermalright TFX would be the best to use.
Depending on the CPU die, I'd recommend using the X method of thermal paste application on a square die... and a line method on a rectangular die.

That should work fine.

 

@Phoenix

Update: I decided to do another repaste especially on the CPU and i got it right this time. I used the line method instead of the rice grain method on the CPU and there was a massive difference. When running Cinebench R23 i ended up with a score of 11660 and my CPU temps only reached to 92C when running on performance mode. I would suggest to repaste again with MX-4 if it'll make a difference or use a different brand.

 

That's awesome. I'm more curious about your heatsink tighening method than your paste method.

 

Nothing special. After putting the heatsink back on i press on it and then tighten the screws 1-6, for modern heatsinks it's normally fine but to be completely sure you have even pressure you can do 1 full turn on each screw and repeat until they're fully tight.

 

You must have gotten really lucky and positioned your heatsink in just the right place... I don't know what I'm doing wrong but I can only score 10,000 on cinebench and my cpu is thermal throttling. I've repasted at least 6 times.

 

I ordered a new heat-sink from lenovo and have some grizzly kryonaut on the way... I'll report the results here in a few days.

Hopefully it fixes my thermal problem.

 

Im not sure about that, i usually put it in right every time. This time i used more paste and the line method and it worked out better than i hoped. Even in games my CPU temps only reached to 87C after an a hour of playing RDR2. You could try spreading the paste on the CPU dye until its fully covered. Like i said i used SSY-157 thermal paste which i heard it was a good paste, I hope your new heatsink and paste will help solve it.

 

I tried the Grizzly Kryonaut it performed worse than the MX-4 on my laptop.

 

I just ordered some Thermalright TFX. I hear it's really good for laptops, I will apply it and post my results here.

Hopefully the TFX will solve my problem. We'll see how it turns out, if it's successful hopefully it will help others who are having the same problem I am.

 

Just wanted to update... I applied the TFX and I am now scoring 11,000+ on cinebench R23 and temp is maxing out at 96-97C.

Problem has been solved, wasn't a heatsink issue.

Do not use Grizzly Kryonaught, AS5 or Arctic MX-4 on a legion laptop.

Use SYY-157 or Thermalright TFX.

Thermalright TFX looks to perform well with low mounting pressure. Perfect for laptops!

 

I decided to try some thermalright tfx it was either that or ssy-157. The thermalright tfx solved my problem...

These laptops like the thicker pastes better it appears.

 

Just a quick update... My 4800H now idles at 39C after disabling boosting... I've never seen this CPU so low!!!

Thermalright TFX is some great paste for laptops!

 

Update on the Thermalright TFX.

The paste seems to have pumped out.

Right after repasting I was scoring 11k+ on Cinebench R23 and a few days later I'm only scoring 8,900.

Never should have taken my laptop apart the stock paste was fine... Jeeze.
