Hello, I have an Acer Aspire E1-571G bought 3 or 4 years ago, I don't exactly remember.
The games I play are WarRock and Hearthstone: Heroes of Warcraft.
The games works perfectly when the PC is cool, 60 FPS because of VSync so if it would be off it would easly go to 90-100 FPS. After some time, it start lagging, maybe 30 seconds, then runs ok, then lagging 1 minute, then works ok, then lagging 3 minutes etc. On both games.
I thought it is because overheating, now I bought a cooling pad(Deepcool N200) which is doing a great job, I see a considerable difference but I still have fps spikes/drops. I don't know what to do, I tried a lot of things even unparking CPUs. Please, help me!

If you were having a problem before, and then adding that cooling pad improved the situation, then it seems to me that further cooling is an obvious answer. It makes sense, as games can be hard even on desktop computers with good cooling.

The CPU in your laptop (maybe the GPU too) is likely still overheating. It's just not doing it as much now that you have that N200 cooler. You need a cooler with a bigger fan, more fans, or both. DeepCool has models with fan sizes up to 200mm. I'd suggest a cooler with two 140mm fans or one 200mm fan for best results.

If the problem isn't cooling, it might be power. Make sure that the Power Options Control Panel in Windows is set to Maximum Performance.

Hey,
1) Drop the settings really low, with VSYNC ON and see if it runs a lot smoother.

If it runs smooth then just adjust the settings to the optimal balance of stutter vs performance.

2) There could be other issues as well, and upgrading to Windows 10 may even help but it can be a hassle. If you have W7 or W8 it's a free upgrade so consider doing that but you'll want to play appropriately.

3) Core unparking rarely helps. In fact, if CPU or GPU temperature is the main problem that will make things worse.

So...
pretty sure it's an overheating issue because as said the cooling pad apparently helped.

4) *To be clear, if you use VSYNC you'll get stuttering if you can't output at least 60FPS (60Hz monitor). You won't get screen tearing, but you will get stutter due to different frame times (missing refresh update). So you get a mix of 1/60th, 2/60th and 4/60th second frame times.

So..
One solution (aside from dropping graphics settings so you don't go below 60FPS) is to force on ADAPTIVE VSYNC to the game. In NVidia Control Panel-> Manage 3D settings-> add game-> Adaptive VSYNC->SAVE

You'll get VSYNC toggle on and off automatically. (again, you get screen tear below 60FPS but not the stutter caused by sync mismatch)

5) NVidia driver updated?
I've updated laptops in the past which only worked using the laptop manufacturer driver. When i upgraded to Windows 10 I was able to use the default NVidia drivers from NVidia's main site (auto detect), Intel too. I had problems with AMD dual-graphics setups though.

I have uninstalled all my NVIDIA drivers and installed 'em again. I downloaded an app that helps me to find out new drivers and I installed 'em all. I will try what you say with the VSYNC and see how's going on.
ATM I don't have money for another cooling pad, so it's out. Maybe next week I will go for a clean of dust at a service, cause if I try to do it with my hand I will broke out my PC. I also have windows 8.1 on my PC(dual-boot) and the exactly same issue.

I don't find ADAPTIVE VSYNC!

In Manage 3D Settings of the Nvidia Control Panel, you have to be in the Program Settings tab. In the drop-down find the first game you're having problems with. With that game selected, change the Vertical sync setting to Adaptive. Then select the second game, and change the Vertical sync to Adaptive. Then save.

Note that the Adaptive option will only appear if your GPU can support it, so it might not be there.

Other than that, save up for a better cooling pad.

Are you running Windows 10?

Windows 10 fixed a few issues people had on laptops due to older video drivers and how the CPU is managed.

My dad's 8600M GS GPU for example only had a video driver from five years ago or so (I couldn only use what HP provided as newer NVidia drivers from NVidia itself would not install). (It had Vista then W8 via $40 upgrade then W10 for free).

*If not clear, when I put on a clean copy of Windows not modified by the laptop manufacturer I was no longer forced to use specific drivers. This may have resulted in loss of functionality on some keys related to video functionality but otherwise things worked better (this non-updating of video drivers for mobile has to stop...).

Anyway, when I ran benchmarks with 3DMark2001 on Windows 10 and then compared to the scores before with Vista there was a 30% difference.

We have already answered your question.

You were having lots of FPS spikes and drops. You added a laptop cooler which made those spikes and drops lessen considerably, but not go away completely.

You need a better laptop cooler with more/bigger fans.

If you cannot afford a better laptop cooler then you need to lower the resolution and/or detail levels of your games so they don't make your CPU/GPU overheat.
