[Zephyrus] Do I need to repaste?

I've got the 1070 model of the Zephyrus. I'm thinking I may do a repaste but am posting here to ask whether this is necessary and to ask for advice towards appropriate steps.

• Why am I considering repasting?

I want my laptop to last ~5-6 years and I'm worried about heat produced affecting the lifespan. I game ~10-20 hours/wk. I will be going back to school in 2 years and won't be able to afford a new laptop in the future.

• What do temps look like now?

Running prime95 small FTTs 8 threads for ~27minutes produces this at an undervolt of -125mv. Idle is stable with 39-40C averages.

• Why am I worried?

To be honest: I have no idea what I'm doing when it comes to a gaming laptop. I've always owned a desktop and this is a desktop replacement. I have repasted desktops I've built before. I want to be sure before I do repaste that it's necessary as I am afraid I might ruin my unit. I need to have a laptop for the portability it affords or else I would stick with desktops. I know I'd like to have temps under 80C. Considering that my best undervolt produces the temps above, I'm worried I have a bad unit and need to repaste. I need advice if this is a necessary step to ensure my laptop lasts as long as I need it to. If you know that the laptop will be fine at the current temps and can last for 5-6 years without a repaste, please tell me. I'm interested in doing this to maintain the longevity of the laptop. I don't need to OC but I do want to maintain current performance.

• What other options am I considering?

Trading up w/ cash for an Aorus X5/X7 or possibly a delidded Clevo/Sager/Origin unit. Trading down for an EVGA SC17. As long as I can ensure it 1.) looks professional 2.) will have great performance and 3.) will last quite a while, I am up for suggestions.

Thanks for any help anyone can give me!

 

Well, the Zephyrus is a thin and light notebook, so you can't expect temps to be great, but I would say that if your temps are like that with prime 95 small FTT (with AVX/FMA) then it is in line with that model, you will probably be in the mid 80s when gaming, except for some very demaning ones like ACO, BF1 etc. Laptops run hotter than desktops, so it is normal, as long as you are not thermal throttling you can wait to repaste until the temps creep up or are really bugging you. On that particular model, with a very good non conductive paste you can expect around 5C difference (more or less). That being said, I would repaste because that model runs hot, and even a couple of degrees cooler would make me happier.

 

Thanks, I'll do that then. By the way, on games it is no better really, except by maybe 4C. That was simply one game of Dota 2, not even anything demanding.
