Laptop overheating issue

[MrKev]

My brother's laptop has suddenly started overheating and when he's watching videos on YouTube etc. his laptop tends to turn off by itself.

 

Any ideas on what the problem could be/what to do? The laptop is a little over 3 years old.

 

Specs:

Acer Aspire 5745DG

 

Temps with no browser open:

 

Temps with Firefox open (similar temps if Chrome was open instead):

 

Any help is appreciated, thanks.

remove the back of the laptop and clear the dust from the vents/fan. You will often find that when you remove the fan (possible new thermal pasted needed after) you will get a layer of dust building up on the inside of the fan grill and it may be stopping the fan from spinning.

Remove the kitten from the fan.

Have you or him removed the dust from it recently?

[KingDaddyDaniel]

If you can't manage to get the back of the laptop off, take an air compressor and air nozzle and use short bursts of air through the vent holes to clear it of any dust.

Heh only 12 simultaneous tabs of ''youtube''? You amateur...

Sidenote: Who just has an air compressor sitting around?

It's a 1200x900 screen on the laptop and I use an external 1920x1080 monitor. the main drawback is my 1Mbps down connection

usually, if you place a laptop on a fluff surface, it suffocates and you get these problems, make sure its either on a flat surface or a stand and removed dust from intakes. no need for compressed air, just use a blow dryer.

DO NOT USE A BLOW DRYER

if you do not have access to an air compressor, then buy a $5 can of compressed air

Have you:

-Bought a cooling pad

-Checked your thermal paste

-Checked if there's any dust buildup

 

Please check this and give us your feedback

 

I'm also having laptop overheating issues... It usually gets a bit better when i use my father's air compressor, which btw @SuperPug is actually lying around

[MrKev]

He hasn't removed the dust from it anytime recently. Would I have to open it up all the way to the CPU fan and deal with the thermal paste too?

why not?

[KingDaddyDaniel]

Heated air from a blow dryer is dangerous. It could start a fire in parts that aren't supposed to get hot, overheat those said parts, or even, worst case scenario, melt plastic

Also, the air isn't focused, causing heat to transfer to unwanted areas

A vacuum cleaner? I used to do it on my xbox 360 without problems

Thanks for the tips . My brother hasn't done any of the 3 things listed however he's bringing his laptop back from university next weekend so I thought I'd try and buy some stuff like thermal paste before he gets back to try to fix it (as I won't be able to identify the issue, buy the required stuff and fix it all on the weekend since he's leaving on Sunday). He's not really good with this stuff so I'll have to do it for him lol.

Change the thermal compound for a really good one. Had the same problem as you. Changed it for IC diamond or similar OP shit and laptop fan wasnt event spinning when watching yt videos
If you have the skills for it ofc. And also check som videos on yt with disassembling it and see if you have metal to metal through thermal paste contact on cpu or if you have thermal conductive pads there.(something like heat conductive rubber) Change that also, it will be stiff. Let us know how it worked out !!

Thanks for the advice. I watched this video. It seems to be thermal paste on the CPU however I'm not sure about the thing he pulls off at around 3:55 in the video? Is that a thermal conductive pad? He replaces it with some aluminium tape at 6:10.

That black thing he pulled from the heatsink near the fan ? Looks like some heat resistant tape he replaced it with to hold the fan together with heatsink (because temps are around 70°C = 158°F normal duct tape could melt or the glue wouldnt hold properly ). That black sponge like thing will be needed in assembly that is to keep the fan from wobbling and keeping it quiet from vibration. If you are carefull enough you will manage to use the old tapes and dont have to change them. It has no effect on the outcome temp. Looks like thermal paste and your skill is everything you will need. Just dont forget to wear an antistatic bracelet or something so you wont create a charge and damage something. And dont spread the paste as the guy in video (it will create air bubbles).

That's alright then, I'll buy some thermal paste (idk what yet). How confident are you that this is will solve the issue? Could it be something else besides dust causing high CPU temps?

99% it is bad thermal paste. Manufacturers sometimes deliberately use cheap thermal compounds in order to make high temps. and making the laptop go wrong as in your case. I bet you your thermal compounds used by manufacturer on cpu/gpu will be dried out and hardened. They do this so laptops would function for little over 2 years (2 years is minimum warranty in Europe) and the malfunction so most of the people couldnt do anything about it and either pay someone to do it or throw the laptop away. i have about 20°C lower temps as you when i am running chrome with yt playing and some downloads  and i have a 13,3inch laptop so a smaller cooler as well.

grab anything around 6€, £5, 7$ (dont know where are you from) from Thermaltake, zalman, cooler master, arctic, antec...

try to clear the dust

[MrKev]

Quick update. I've cleaned the laptop and replaced the thermal compound. After putting the laptop back together, when turning it on it wasn't showing anything on the screen. After removing and connecting the video connector a bunch of times the screen now works. Only issue is that there are a bunch of green pixels all over the screen and idk what to do. The connector doesn't seem loose because I've connected it again around 5 times. Any ideas?

 

Edit: tried to disconnect and connect the connectors again and I see a black screen upon boot again

[MrKev]

Nevermind. I'VE FIXED IT! It only took me the whole day but it's finally done lol

[blackberi]

what are the temps ? make benchmark and post temps, i am really curious how big of an improvement it is
