Hello everybody I have my laptop since 2010 but I think it has serious CPU problems. It has i7 720qm in it and it was always running hot but nowadays it's completely useless...
Here's what happened:
In 2011 - idle: 60C, render 95C, games 80-90C.
In 2012 - with cooling pad, idle: 55-65C, render 95C, games 90-95C (!)
In 2013 - stronger cooling pad, idle: 60-65C, render 100C, games 100C (!!!)
1s half of 2014 - HDD corrupted of heat (but I saved it when service couldn't hehehe)
At this time, I turned on Power Saving and underclocked it to minimum 0.9ghz.
Now ON 0.9ghz THE TEMPS ARE 72C idle, on stock 1.6ghz, 82-85C!!!
I thought it's thermal paste problem but I touch the keyboard and it almost melting so hot... and the fan puts out a lot of heat so maybe the thermal paste isn't the problem.
And like 2 months ago I wanted to do a memory test (I took out the cooling pad for some reason) and at 40%, it turned off (I think it reached Tjunction) and the motherboard heat and voltage monitor disappeared. I'm extremely curious now what voltages it's working on but I can't see it since then.
So I don't know why this is happening, what causes the overheating? I fear that my second HDD will be ruined because some months ago with cooling pad it was on 40C but now it's on 52C

Is it possible that yor cpu cooler fan has stopped working or that dust has accumulated inside.
I suspect that the cooler was never installed properly. A cpu should idle somewhere around 10-20c. over ambient.
I suggest you take it apart and remount your cooler with new thermal paste. AS5 is good. Clean off the old with alcohol.

From what I have gathered about the Intel CPUs that I have used is. Some get hot. Some don't. Intel has their CPU binning and Sometimes you hit the "Silicon lottery" most times you get an average Chip, the other times...what is the opposite of winning a lottery?.....ah... I guess other times you pay Intel and they beat you silly with a rubber hose.
I already typed that...Sorry. Anyway 9 times out of 10 we can over state and overthink How bad are Temps are getting, Solve the problem you can, If you cna take it apart and apply new Thermal paste than go for it. If that is to much or to long That you may have to undervolt or underclock. A motherboard can supply more current then necessary to achieve stable Clock speeds

I was stupid and I clicked as best solution but I just wanted to reply
How can I un-solution this lol?Btw I'm unsure how to take apart a laptop. I sent it to check in the store but they said the fan works great (I hear its sound) and they were surprised because after 4 years it still didn't have dust in it. It takes out a lot of heat also. But not enough as I can barely touch the keyboard it's that hot.

What model is your laptop?
Acer Aspire 5940G don't worry it's not even on Acer's website. Everyone acts like this laptop isn't exist and I can't find anything for it.

Yep but it's not normal that it hits 100C and thermal throttles all the time. Also I UNDERCLOCKED IT TO 0.9ghz I can't underclock it more, it is the minimum and slow as hell. I want to render and game with it but then it quickly reaches 100C with cooling pad, without cooling pad, it turns off at 104C. Not even talk about that I can't use it as a laptop because it makes hot dogs of my legs.

I unselected it for you.
Keep looking for the problem.
Normally you can download instructions on how to take a laptop apart for service.
I think this is yours:

Can you tell me the Make and model of the laptop. Sorry if you mentioned it in this thread already but I am very tired and I will remind myself to check out some sites and references I use sometimes. I too am concerned with Temps and I can imagine your distress with that portable heater you have right now. When I am back online I will post a reply......
...laptops can have so many screws and it is usually disassembly is a last resort as they are much more delicate than a Desktop...

I've had 3 laptops, I've paid for 1, when something goes wrong you call the manufacturer as often as possible until you find someone that will offer you replacement/refund. Also don't worry about how old your laptop is, you can still get a refund/replacement with laptops over 5 years old as long as your persistent and sincere.

Those instructions... have deluded me
Years ago I locked the BIOS with password and I can't access it (actually I know my password but the BIOS won't accept the it). The instructions said if I take out the RAM modules there will be a CMOS jumper to clear the BIOS. But there isn't. Strange (these are indeed the right instructions for my model but they still show a different image of the opened place of RAM).Back to the topic:
Maybe the overheating is caused by a degraded CPU? Because I rendered a lot of things with it and it was always hot so maybe it is damaged and runs hotter? I know a few things about CPU degradation but I think it's just if I overclocked the CPU.

Acer Aspire 5940g yep I said it already. And yeah I have seen how to disassembly it, and it's extremely hard for my model, worse than for other laptops.

Laptops are notorious for sucking in cat hair, dust lint etc... Good advice. I don't think Mac laptops don't have fans anymore iirc.
