Hello everyone!

About 1,5 week ago I've bought a new Lenovo Y50-70.

First few days of run the laptop performed really well. I gave it some benchmark tests and so on just to see how it can handle itself. I was more then pleased with it. On high performance and demanding benchmarks and games as well it gave good results AND it kept cool.

While playing GTA 5 for many hours straight, it didn't go above 60-62 degrees(neither the cpu or vga) without a cooling pad, only with a pad which increases the angle the laptop stays on the desk. Now this is what I was looking for, a great laptop with good performance and cool temperatures.

However. A week passed when I didn't use my laptop as I had no need for it, because I had travelled home and had my PC at my disposal. 

Now the time came when I had to use the laptop again and I noticed something. While previously I got away with 60 degrees while running demanding games now I get 80 degrees for the same thing. Browsing pushes it up to 55 degrees which I find rather unpleasant. The laptop got no physical injury(haven't dropped it and took care of it like its made out of glass), and it rested in its laptop case.

I tried to use a laptop cooling pad as well, it resulted in nearly no difference. The laptop cooler pad was a thermaltake pad with a 20cm fan.

I would like to know if anybody else had similar problems like I do now, and if you found any solution to it. Because to be honest, I'd like to have this laptop for a while, and I understand that 80 degrees isn't that much, but its still more than what is healthy for the hardware in the long run.
(All degrees are in Celsius)

EDIT.: I Ran a 3DMark Sky diver test to see what's up today. While the test ran I reached 75 degrees on the CPU again and even though more than 10 minutes passed, the CPU still doesn't want to cool below 50 degrees no matter what.

EDIT2.: My sister has the exact same laptop, and even though its 2,5 months old, when she runs the same tests I do, her laptop doesn't go above 70 degrees.

Did u really have 60 degrees while playing GTA 5? While I play CS:GO, which isn't that demanding at all, my temperatures are around 70 degrees, and when I try more demanding games with 1920x1080 resolution, my temps sometimes reach even 90 degrees. So in addition to flickering, apparenlty this laptop gets ovearheated too. Well, I really need to send this laptop for service. As for your problem, I have no idea what could have happened, sorry. Maybe the dust filter got dusty?

Yes I did have 60 degrees on GTA 5. I was just as surprised, but it stayed like that for 2-3 days, so I take it as a base line for what this laptop can do. Another thing that makes me more sure that I really did see 60 degrees is, that my hands were not burning on the keyboard. Now they do.

Edit.: Dust filter looks about as clean as it was new. I would take it apart and clean it but unsure if the warranty gets void or not.

Don't touch the airfilter. It is permenantly glued to the bottom lid. It will get dirty, but definetely was a bad idea from the getgo to put an airfilter like the one on the y50-70, it is a "catastrophe waiting to strike". It does keep air clean that goes into the laptop, but it slows airflow dramatically. When I had my y5070 I could see a whitish type dust covering the whole filter exposed to the outside air flow, and my laptop did heat up quite a bit.

I downloaded a software to make the fans go at higher speeds, hoping it would cool the laptop down more. Even though you can hear that the fans are actually working, air isn't actually flowing. I put my hand to the vent where the hot air is supposed to come out, but I only get some really weak current from there.

So I think I should open the case and blow it clean with some compressed air. Question is...do I lose my warranty if I only take off the back panel to blow off the dust?

Other thing that came to my mind is that I have some Gelid Solutions GC-Extreme around which was really really useful for my old laptop as it pushed down its degrees by 10-something. Can I also apply my own thermal paste without losing my warranty, or do I have to send the laptop to service for this?
