Acer 5820TG temp issue

Hello!

I got a notebook Acer TimelineX 5820TG
- Core i5 460M 2.5Ghz
- VGA Ati 5650 1gb
- 4GB RAM DDr3
- ...

I instaled SpeedFan and HWMonitor, both working, but there are things that are really bugging me.

When I do things that uses CPU and GPU a lot, like Crysis 2 (GPU at 99% usage), the temps go too high:
-CPU (i5 460M) goes up to 103 degrees Celsius (218 F)
-GPU (HD 5650) goes up to 99 degrees Celsius (210 F)

I'm using Thermaltake Massive 23LX for cooling, and I put Arctic Mx-4, but with no great changes.

I don't know if that is related with issues with games that uses too much CPU instead of GPU (old games for ex).

Someone could help me? Is it possible to be notebook sensors issue? Thx!
(Sorry if I posted on the wrong session)

 

Hello and welcome to NBR!

You serious? i5 at 103C?

Well, I wonder how it does without a cooler if this is with

However, back to your problem; You have a good thermal paste, perhaps you pasted in a wrong way? Very very thiny little chanse but it can be the senors, althrough, I have never seen anything like that before.

Also, HWMonitor is what you should be using, I quit using SpeedFan about 4 years ago

But hmm, I can't imagne any other issue that will casue this high tempratures, what it can really be is that your laptop have dust inside?

Some people really don't understand how serious that is, I helped out another member few days ago, and he had a very very little amount of dust on the end of the heatsink and it caused his laptop to overheat and shutdown.

Perhaps, your heatsink is bad? How old is this laptop?

 

Since the 5820TG does not have dual fan/independent heatsinks, it could be a heatsink issue. The 460M does not run that hot normally. Normal operating temps, even in the larger timelines is in the 95C range. 103C is not out of the question however. We have seen temps that high in the I7/4820TG models. Since you have a max temp of 105C in the I5-460M, I am surprised you are not seeing throttling or more likely a complete shutdown or BSOD. That makes me think initially that your program is giving you bad readings or your sensor is bad. Bad readings is more probably because of the high CPU and GPU temps.

Before you go start changing paste, etc., make sure you're getting good data. Use HW Monitor and try the trial version of Everest. I think Throttlestop might work as well. If those temps are real, you either have a bad thermal connection (too much paste, etc.) or the fluid in the heat exchanger is bad. Is the fan working? Is the exhaust hot? Is the handrest burning hot? They should be if you have temps like that. How about the bottom of the unit? Hot?

Keep us informed. We'll try to help. Any warranty left?

 

Thanks for your reply!
The internal cooler I guess it is okay, because I hear it working on medium-high power all the time while playing a game for example.

Before appliying the new thermal paste, it was close to that temps too. I applied 3 times my Arctic Mx-4 because I saw no results (only GPU that had some degress less).

My notebook has now 6 months of usage, and I don't have warranty because I got it with an seller that imports products from Canada (I'm from Brazil, and the assistance here sucks).

Thanks for your reply!
I've checked the temps before changing the thermal paste, and it was extremely hot like now. The handrest (left) gets really hot, thats why I use an usb keyboard. And the exhaust is worn too. The back cover, near the exhaust gets extremely hot that it gets insupportable to be touched.

I don't have warranty. My notebook has 6 months, but I got from a particular seller here because there are no TimelineX series selling here in Brazil.

Thanks guys, I will post some temps screens!

 

wow, your laptop shouldn't run that hot. What you say now is basiclly that your laptop is useless without a external keyboard. I'm stuck actually, what I can think of is dust between where the heatsink and fan meets, something like that is highly possible on my laptop. (the design on my 5739G is a bit wired).

But again, I would check your heatsink...

What you can do is boil some water, put one end of your heatsink in the boiled water and the other side you are holding should get warm/extremely hot in a very short time. Watch out for your fingers..
If it does, it is a pass for your heatsink and we can focus on another element, if not, then it is your heatsink.

 

Here this one I got after playing Crysis 2 some minutes


About the headsink, do you mean like this one? (sorry, I have some problems with components names XD)


Thanx!

 

The first thing that I would do is give the vent a good cleaning. If you have the unit apart, fold back the plastic over the cooling fins of the vent and clean with compressed air. If that doesb't help, I would try IC Diamond 7 paste (my temps went down nearly 10C). Make sure not to over-apply the paste.

 

I have a 4820tg, i5-460m, 5650, and I have the same problem =[
I recently got back into playing BC2. However, after mere seconds of getting into a game, my temperatures would sky rocket. The CPU would reach temperatures of over 100C (101~104!!). It would immediately down clock to ~1300 MHz, and I would get choppy framerates as a result; I can only assume this is the CPU throttling.
The GPU is on the hot side, but still functions. I get temperatures of <90. Hot, but nothing that affects performance.
I've tried changing the thermal paste with Arctic Silver 5 (several times), with no results. I THINK I've applied it correctly (a dab on the 2 silver things on the CPU, no over application). I don't use a cooler, even though I plan to get one. Regardless, the temperatures should NOT be this high. I should not be relying on a cooler to play a game that should run perfectly fine.
Reading the other posts in this thread, I guess my last option is cleaning the heatsink? I can only hope that there's a huge dust bunny hiding in there... At least then, the problem will be revealed >.<

Besides the 2 silver rectangles on the CPU, the silver square on the GPU, are there any other places that require thermal paste? There are 4(?) black rectangles that are also in contact with the heatsink, connected with only what I can guess as thermal pads. Do those need to be replaced too? Also, with the removal of the thermal pad on the GPU, I've had to apply more than the normal amount of thermal paste. Do I add thermal paste until the point where the 2 sides touch, and stop before the paste squishes out, or is there a better method?

Thanks in advance!

 

wow that's hot. It's higher than my 3820tg under heavy stress Oo

maybe the fan is not running at full speed (I had that problem on my desktop graphic card, always 60%, I forced it at 80% and it was fine)
If the heatsink is fine, and the fan is spinning at full speed, i don't know what it can be :/

 

Yeah, it's a lil fire in there >.<
I tried running furmark, and the GPU spiked to 90 C in seconds. Stopped the test immediately.
I'm not sure as to how to check if the heatsink is working properly. As for the fan, I'm quite sure it scales with the temperature. With the sound it produces, I'm guessing it works fine. I notice a bit of dust in the fan and some in the vents, but I don't have compressed air to take care of it yet. Would clogged vents/fan be enough to cause the CPU/GPU to reach 90C within seconds of load, or would that attribute to a heatsink problem? Could it possibly mean something else?

 

The AMD turion in my brother's DV6 was heating, and shutdowning. I monitored it at 80 degres in idle. after cleaning the vents, it was at 45 degres (idle).

 

O_______O
Perhaps tomorrow may be the last time I'll have to tear my lappy apart. Until the SSD =3
Any *pro-tips* for cleaning out dust and such? Anything I should pay special attention to?
I will be extremely disappointed if the problem does not lie with ventilation ='[. If it does... \(^o^)/

 

Guys, stop heavy testing your computers. Those tempratures are high enough to simply kill your laptop. And yes, that is a heatsink, give my heatsink test advice a try. Really the only way.. And, I said in my first post, CLEAN YOUR VENTS.

 

Ahhh thanks for all the advice. After taking the thing apart for the 10th time and blowing out ALL the dust (the amount almost make me choke), my lappy is running much cooler again. No throttling in SC2; sadly, there's still throttling when playing BC2 =[
Any ideas to downclock the i5 460m on the 4820tg to keep the lappy from ever reaching a temperature to cause throttling?
Once again, thank you for all the pointers =3 Had no idea that so much dust could build up inside the laptop

 

Glad to hear that it worked out. I would schedule a cleaning every 90 days or so. If you don't elevate your computer while playing BF BC2 it could help.

 

Sorry for re-upping this thread.

When I disassembled my 5820TG for the first time, I noticed that between heatsink and GPU I guess there was a Thermal Pad or something like that. I removed that and put Thermal Compund. But there was a big space between GPU and heatsink, and I had to put big quantity of thermal compound to make contact between the components.

The cooler is working well because I can sense the warm wind flowing out.
Is it necessary to apply thermal pad on GPU (maybe CPU too) instead of thermal compound? Thx!

(sorry for the english mistakes)

 

You can get chopper 0.5 mm or use pads. I usually use pads for the GPU.

 

Also one poster in a x820TG thread adjusted the height of the GPU heat sink so it sat flush on the GPU by bending the tabs that mount the heatsink.

 

OMG I am facing the same issue and now I know why my games are freezing midway. Temperatures are hovering at 100+ . Can anybody suggest a good notebook coller to reduce the temps ? I have this cooler :-
Amazon.com: Antec USB-Powered Notebook Cooler: Electronics

But now its nearly 3 Years old and I think it may be time for a change !

Also can somebody please tell me how to clean the vents ? I dont want to void the warranty !

 

Easy way of cleaning the vents is to use gas duster (canned air) to blow through them. That should unsettle the dust wedged between radiator leafs.

If that doesn't help you'll need to disassemble the notebook and give it a proper cleaning and replace the thermal compound while you're at it.

 

Seriously? Do you even have any warranty left? I've open my laptop first day after checking for issues for about 4 hours.. First thing I've did was to repaste that poor CPU which had some Acer toothpaste on it..

 

Yes I do have warrqnty and this laptop is nearly a year old now , bought it last November from Singâpore. But currently I am in Europe and I seem to have misplaced my free local Extended warranty card as well !

Is this the temp issue because of faulty unit ?

Can I use suction mode from my vaccum cleaner to suck out the dust from the vents ? Any suggestions for a notebook cooler to bring the temps down ?

 

Vacuum cleaner is the last resort. I've seen that work but it may be too powerful. Gas duster is some $10 per can and will be useful in future as you should at least every month or so- meaning before the dust accumulates for good.

 

Hmm I am currently in Switzerland and I will need to hunt for a Gas Duster here but its a little difficult as people speak French and understand very little English.

Do you think if I do a basic install of Windows XP with just the sound card and graphics card driver will it help in reducing my temps ?

 

No- there's nothing you can do software-wise. You'll have to give it a proper cleaning.
Visit MediaMarkt- I know they have those in Switzerland and find a gas duster on your own.

 

Yes they have media markets here , i will try and go there tomorrow . If I try and disassemble my laptop for cleaning does it void the warranty ?


Also any pointers on how to clean vents will be appreciated as well !

 

You are not allowed to do that but no one will notice unless you break something- which you won't.
A service manual will help you to do it right.

 

Ok some thing good to report. I uninstalled the latest drivers , cleaned it with driver cleaner and then reinstalled drivers as publisher in the acer support site. Immdly my temps went down by 10 degrees ! My laptop maxes out at 93 even after 1 hr of intense gaming. SO i am satisfied. I also tried to take apart my laptop but was only suceessful in removing all the screws at the bottom as well as the main cover ( coverig the ram, hdd etc) but then started getting cold feet so did not dismantle it further. used a vacum to do some suction at whatever gaps i could find and then replaced the screws back. So everythigns fine for the moment.

Now for the surprising part :-
CpU temps are lower when the dedictaed gpu is on as compared to when its switched to intel . Is it becuase the load on cpu increases when we switch to intel graphics ?

Idle temps 34 to 37 with GPU and 36 to 40 with Intel Graphics.
