Asus G51VX-X3A Overheating

I've noticed lately that the fan on my laptop has been going extra crazy. I let my laptop sit on the floor in the back of a classroom to charge my phone the other day, and other students commented on how loud the fan started to become. I noticed last night when my laptop was sitting at my desk that it became loud again.

I was using the laptop connected to a monitor with two screens, watching a movie in one screen and a youtube video in another. Firefox started to crash as the video slowed to a crawl. Once Firefox re-stabilized, the laptop shut itself down. I tried turning it back on, and all of the LED lights became solid while the laptop didn't turn on. I felt underneath it and it felt pretty hot. I turned it off and put it next to a fan for 10 minutes, then booted it up.

This time, I ran HWMonitor as soon as it booted up and over the last 12 hours, it looks like this:



The laptop has sat on a table or on the floor over the last 12 hours. The only things I've done to get those temperatures were web browsing and video streaming online. Should it be running that high even with such low activity? I took a can of air I found and sprayed inside of the case, but it was an older can from last year. It might be better to get a new one.

 

Open up the bottom panel and blow compressed air on the fan and vent from the inside out.

 

Tried blowing air on it back then and now it's running at 103C *again* right after coming out of a game. I guess I'll blow on it again.

 

with my computer, i found that using the lastest nVidia drivers kept my GPU really hot even when its idle...

So, I still using DOX 185.85 drivers, I'm idling around the 60C~70C now =P with newer nVidia drivers, it can go up to 90C while idle here =/

 

I'll try cleaning and installing those when I get home tonight. Thanks. Just annoying being forced to low settings Duke Nukem Forever when I know this laptop can handle Crysis 2 fine.

Should I do a driver cleanup before it though? Suggestion?

 

I'm at 76C idle right now....77.

I cleaned it out with compressed air. There is one fan underneath with a vent outward. I blew air in and out of the vent. I installed those 185.85 drivers also. I'm 77 idle 97C load. This made Duke Nukem Forever playable at highest settings at highest 1920x1200, but the temp is at 95-97C. Why is it so high?

 

Does the DOX 185.85 perform better than the latest drivers 275.33 ?

 

Enable powermizer and your GPU temp will drop while idling.

80+ is still high for idle with powermizer off. I usually get around 70 with powermizer off. Clean out dust and maybe reapply thermal compound on the GPU.

When you put your laptop down on soft material, you should keep it upside down to allow airflow, especially on the bed.

 

How do i go about the compound re application?

 

Sounds like you need to do a repaste, ASAP. use IC diamond on your cpu and gpu, it will save your latop

 

Is there a guide for that somewhere?

 

You will need a disassembly guide for the G51Vx if you want to repaste. Repasting basically involves taking apart the laptop, removing the heatsinks on the CPU and GPU, cleaning both the heatsinks and dies then repasting, replacing the heatsinks and reassembling the laptop.

I'll let you find the disassembly guide, but here's how to use ICD7: Application

 

Just bringing up an old topic of the overheating on the G51. I had repasted the CPU and GPU, and apparently I had made the mistake of repasting the NorthBridge as well. When I had booted up and played a few games, my temperatures still ranged from 80 idle to 97 load. Even right now, sitting idle, I'm at 88C.

I used the pea method for applying the paste, but what would be the best way to fix this situation to apply the paste correctly to the cpu/gpu and handle the northbridge correctly?

 

Just open it up and remove the compound from the northbridge with an alcoholic swab.

You might have put to much on or too little, or the heatsink might not be sitting flat or the paste might not have covered the entire chip. If you have done it once go back and have a second attempt you dont always get the results you want first time round, or you might not see better results. Make sure the airflow is clean no dust or dirt.

There is no right method of application but the pea method allows the heatsink to evenly spread the compound its the only method I use to reduce the possibility of bubbles forming. Are you using ICD? if not try it because most swear by it including me, its thick and works very well.

At the end of the day if you still notice no change it may just be the cooling of the G51 the 260M GTX runs hot and 88oC is nowhere near the 110oC TJ temperature.

 

Okay, I went in, removed all the compound from the northbridge, gpu and cpu with swabs and alcohol. I reapplied with the pea method, and used a slightly larger pea for the GPU since it was bigger.

I cleaned out the air vent with a can of air, blew into the fan and into the vent. I rebooted, and only watched the temperature of the GPU climb from 50C to 74-75C. I just now ran Futuremark Vantage while I was at work and left HWMonitor.

I got this:
