what's the heat limit and safe temps for a laptop gpu?

[blakflag3]

I have an AMD 8670m 2gb graphics card on my laptop that i overclock when gaming and the gpu temps are reaching the 70's (max at 73 degrees) after an hour or so of use,i would like to know if these temperatures are safe and what is the maximum allowed temp for this gpu,i also want to mention that this usually happens when playing new AAA titles mostly and not on all games or applications
appreciate all the help you can give,Thanks.

Those should be fine for the GPU. Laptop GPU's have a higher temperature threshold than CPU's. My second gaming laptop was an Asus G60VX and 70 degrees Celsius was it's idling temperature, light gaming would push it towards 90 plus Celsius! I'm sure other's would say the same unless your laptop has a high performance cooling system in it.

I eventually added a ton of copper heat sinks and RAM covers once it was out of warranty and made a vented hole in the bottom of the laptop and got the idle temps down to 30 or 40 degrees, but I don't recommend it for a laptop under warranty or not a serious overclocker. 😛

But yes, those temps should be perfectly fine.

thanks for the info,can you tell me about cpu heat levels if you happen to know about it(what's safe,what's too much),and if using a cooling pad and/or swapping the stock thermal grease with an aftermarket one helps and by how much
thanks again for the help

on my laptop (ASUS N550JK) the cooling system links the two together so my GPU (850M) and CPU (I7) stay at around the same temp, in planetside 2 they both hit low 90's

Yes, laptop's will run way hotter than desktops, and that also relates to the GPU in a mobile system operating on higher heat than a desktop. You can also only do so much with the cooling on a mobile system to keep price, noise and weight down to a minimum.

For further clarification search around for common laptop and gaming laptop temperatures, and try to compare against a system with similar specs and a similar cooling solution. Otherwise I say you're fine.

You could always re-apply thermal paste, or a high end thermal paste, but this will void some laptop's warranty. Just make sure NOT to break a seal unless out of warranty, and only apply thermal compound after a little research.

nowdays the firmware is very good at making sure the temps stay at "reasonable" levels so just keep that in mind too, you computer will not be afraid to throttle down to keep temps in check, where you have to worry is when it starts to throttle too soon due to dust buildup, bad thermal paste, etc...

This is very good info as well. Be sure every few months to blow any dust out from the vents/heat sinks or clean the filter if your laptop has a removable one. Check for BIOS updates as some may have firmware updates to help manage heat better (most laptops have BIOS update tools that you can run safely from the OS). And if you choose to do so, make sure it is OK by the manufacturer to apply better thermal paste and check to see if that will void your warranty or not, some vendors are picky about that while others are more lax.

The temps you are experiencing is normal. The max that most people say for a laptop is 90 degrees c for both gpu and cpu. You can always check on the cpu and gpu manufacture's website what the saftey limits are.
