Lagging after laptop too hot

Hello,

I have an acer aspire laptop, amd 4 core 4 RAM, with a 1GB dedicated AMD Radeon Mobility 5650 card.
From the earliest time my computer has always felt really hot when I use it (my nephew in the UK also has an Acer and his is the same).
I was playing WoW on full screen and smelled burning. I immediately shut the computer off before even checking the temp and played in window form from then on. I also took the laptop apart, replaced the thermal paste and cleaned out any dust (which wasn't that much TBH).

The computer ran fine after this and I always have speedfan on when running any games (which I play on lower settings and in windowed mode). The thing is I have gotten accustomed to it running mid 80s C, No smell, no lagging, no cutting off.

The other night I also had Teamspeak open while playing World of Tanks and it started lagging and I looked at the temps. The CPU was 95C and I think the GPU temp was close. I shit TS off immediately and the temps cooled (but not sure how long they were at the temps).
I played for quite a few hours and did not let it get that high again and there was no lag.

The issue was the next day I opened Photoshop and it said that my video card needed an updated driver. I opened Illustrator etc. without the error.
I updated the driver, restarted my comp but it still gave me the error and stated that it was disabling some of the options.

I recovered my computer to earlier that day and then PS did not give me the error again (and assume that it would have reverted to not blocking these features).
I played tanks and it sometimes lagged but not always.

The issue was the next day all my games seem to be lagging. I am getting an FPS of max 54, sometimes getting down to single digits but only for a second or so. I tried playing two videos on Amazon at the same time and they are running fine.

The weird thing also is my temps are rarely going above 70 which is REALLY strange.

Have a damaged something and if so how can I check?

Thanks so much

Well you should stop stressing your laptop if it's hitting 70ºC+ temps in the CPU, you're shorting it's lifetime and most likely suffering from throttle which will give a lower performance than expected.

When you say lagging, you mean lag (internet response time higher than usual) or FPS drop? if you meant lag then your laptop has most likely nothing to do with it, maybe your NIC interface is getting so hot causing disruption in it's handling of packets, beyond that, it's all ISP sided.

FPS drop however would go directly with your issue of overheating, throttling occurs and the system delivers a lower performance than usual.


The thermal paste takes a few days to make complete contact, after said days are done, you will notice lower...

Thanks so much. Actually it was the first time my computer ended up majorly overheating last year when I changed the thermal paste and although it made a small difference I still cannot play games in full screen mode (but I understand laptops are not really made for gaming (at least not this one).

Unfortunately I don't have a place for a desktop.

My fps was running at 45-50 and then down to 35, but others in the game had similar readings so I don't think mine showed that much of a difference. It just seems my character is moving slightly more jaggerdly with only a few lags where I jump forward or something.

I understand though that I may be causing a lower life-span. As I mentioned though my temps are suddenly running much better (60s for the most part, even lower at times), and that is why I thought that maybe I have lost some of the card/CPU and hence it isn't able to generate as much heat.

I played tonight with these lower temps and it actually seemed okay, although WoT is still lagging (tank stopping and then jumps forward). My internet isn't the best either though.

I am going to get myself a new and better cooling pad and then just make sure I never let the temps get up that high again, but it has been impossible in the past to keep temps lower than the safety levels that you mentioned. I really think it is an issue with Acer computers (as I mentioned my nephew's gets extremely hot too and I had one in the UK that did the same but I did not know about speedfan at the time, I did not run games on it and had it on my lap or on the bed so not sure how hot it got.

I will keep an eye on it and then reply back if there are any more issues. What I would like to know though is if there is a program I can run to check if the card and CPU are working as well as they should for their model (but I also fear doing the stress tests that overheat the computer).

Thanks again.


 
Most laptops have a bad design (for keeping low temps) for gaming, even high-end ones.

Yes, a cooling pad is practically mandatory due to my sentence above.

The jumping you have in WoT is indeed a problem with your connection, could be the ISP, could be your wireless connection, if possible try connecting with an ethernet cable to your router/modem and see if that solves the issue.

Could also be your antivirus/ windows update or something/someone else in your network using your bandwidth.

Any good CPU/GPU will stress your system, I'd give that a go when you have the cooling pad, running Prime 95 for an hour should be enough to determine if there's any issue, furmark / 3dmark for your GPU for 30min should do it as well.

However most likely everything is OK, when the CPU/GPU fails, usually it will either artifact in-game or crash/hang/restart your system.
