Get out the Air Cans!

I know that this is probably a "Duh!" in most peoples books. Some of you will say, cool story, I knew that. Just a bit of discovery for me:

When I first got the laptop and started looking at GPU temps, they were as shown:

Initial temps:
Idle: ~55C
Load: ~85C

Recently, my G73JH has been idling quite a bit hotter than it used to. Temps were as shown:

Idle: ~70C
Load: ~95C

I thought, hmmm.. Maybe I should "repaste" as seems to be a popular topic or answer to this problem on this forum. I have some skills taking computers apart, but I haven't recently been doing much computer repair, so I wasn't ready to commit myself just yet.

The other night, I decided to whip out a can of air. I just hosed both exhaust vents out and a ton of dust came out.

After "Can of Air" fix temps:

Idle: ~54C
Load: ~85C

I also noticed that the CPU was running quite a bit cooler, but I never really concerned myself with paying attention to those temps.

So, lesson learned: Try cleaning before taking apart!

Hope this helps out some people in similar situations

 

A few questions, if anyone wants to answer:

1. How often should this be done?
2. Which can of air did you use and where did you get it?
3. Can a can with too much pressure possibly damage any internal parts if you apply it too close?

thanks in advance.

 

Good questions, but I really don't have any answers.

I had two cans of air, both were old ones that have been sitting on my shelf for quite some time...

 

Where do you buy the can of air?

 

I can confirm it works!!!!!

My idle temps were:

65-69-67

Right after the cleaning with compressed air my temp were:

55-60-58

Now GPU clock tool is reporting (not complete idle):

53-58-56

I just can say...wwwhoooaaa!!!! the amount of dust particles that came off through the vents were incredible. Now my laptop is cold as new... and no repasting needed

 

how exactly do you spray the laptop without disassembling? blow it into the vent behind?

 

let me get this right.... you blew air into the "exhausts" meaning the two openings under/behind the screen, and dust came out...from the same place ?

 

In the Vents!!!!

Look in the back side of the screen/laptop, you will see two enormous vents (on in the right and other in the left)... just push compressed air in the vent and you will see dust coming off the vents, next, enjoy your new temps.

 

seems easy enough thanks, will try it when the time comes

 

Repasting is to be done when your stock clocks CLEAN computer has high temp readings.

You just... cleaned up your dirty laptop.


Man, these topics get redone every so often, makes me feel like we have hit a wall with how much information the end user gets. Stuff like this should appear on TV more often or something.
