Acer 5820TG thermal sensor issue

Hello again!

PLZ READ ALL
I have done some questions here, but I got no results for my problem.

My notebook is:
Acer Timelinex 5820TG
Intel I5 460M
4GB DDR3
VGA HD 5650M 1GB

The issue looks really simple: My CPU and GPU gets really bad temps, more or less 105 C (with Throttle Stop). When I got this notebook, everything was fine. I was getting around 60FPS on NFS Hot Pursuit (maxed) - and other games had suffered too. But now I get about about 25FPS, even with Throttle Stop activated.

Before someone asking, I have to tell that I have already cleaned it, disassembled and changed the thermal pasted, applied copper shim mod, reinstalled the OS, but nothing resolved. The cooler flows warm air (so it is working at least).

I presume that it can be thermal sensor issue.
Question: Can I replace the thermal sensor of a notebook? Is there a way to recalibrate thermal sensor like old Dell notebook (Fn+Z) ?

Plz, I need a solution. I was closely going to throw this computer after buying Clevo 150HM.

Thanls

 

You dusted the inner parts of your notebook, you reapplied a fresh coat of thermal paste, you added copper shims, you're using a laptop cooler, and you even re-installed the OS! Total overkill!

Dude you're not going to be able to milk your notebook for cooler temperatures anymore. Calibrating the thermal sensors isn't going to make the notebook display better temps.

A few things that I would do myself. I would toss the copper shims. Use high quality thermal paste (artic silver 5, MX-2, ect). Download an application that displays the internal temps like HWMonitor Pro from CPUID - System & hardware benchmark, monitoring, reporting. And call it a day on trying to further cool a low end notebook.

Alienware is the best notebook for gaming but building a gaming rig is way better.

 

Thanks for the reply!
My copper shims are really clean. Im using good thermal pastes (MX-4 and Artic Silver 5). Downloaded HW Monitor too. Im using cooler pad too (Thermaltake Massive 23). And I bought infrared thermometer to measure - you see how much did I expent on this notebook XD.

The infrared thermometer shows a normal temperature. I guess its really the thermal sensor issue. Unfortunately I cant buy a Alienware here in Brazil (I would have to expend more than $3000 for what Ive got from a Clevo - great taxes over here). And I need something portable because Im studying in a different city, and I carry my note all the time.

I just need to fix this notebook to sell it. I cant expend more money on that. Im praying that it can only be thermal sensor issue.

Thx (just stressed with Acer brand -.-)

 

I have three notebooks (2 Acers and one Dell). So far I'm way more pleased with Acer. Acer customer service is so much better than Dell and I haven't had any hardware issues with Acer. I'm never buying another Dell product or calling ever again for service.

Sometimes notebook manufacturers fail to design a decent and efficient cooling design. intel i5 cpus do get really hot. I would google to see which are normal temps for the i5 in your notebook configuration.

So far I've heard that Toshiba notebooks are very reliable but they're not meant for higher end gaming. I know that Asus does make gaming notebooks and they're economically attainable.

So far what I've learned from having a notebook is that the screen can fail at any point but luckily that its a do-it-yourself repair. Same thing with an optical drive (dvd drive). Clean the dust out periodically and reapply a coat of thermal paste every 6 months. A fried motherboard is the worst that could happen.

 

Have you tried updating the BIOS?
