I'm sorry?
I am looking for advice about what I should do about the temperatures of my laptop.I have had it for about 3 years and it has been running at very high temperatures for a while, its not rare for the cores and gpu to be in the 90's and the other day I saw my gpu was at 102C !!!
These are the temperatures shown by speedfan with only gtplanet, skype and msn open.


What should I do?
 
Try opening it up (not while running) and vacuum all the dust out. Also check (while running) if all the fans are working properly.
 
I would not use a vacuum cleaner. The motors create static electricity and that can easily fry the sensitive electronics in your laptop. Use a can of compressed air instead. I'd also have the thermal paste(conducts heat from the CPU to the heatsink by filling in small gaps that you can't even see) changed. After three years the thermal paste should be fairly cruddy and dried out and it won't conduct heat like it used to(which would easily lead to your high temperature problems).

I'll keep that in mind, however I have never replaced thermal paste before so I might just clean it for now, thanks anyway

Cans of compressed air usually create tons of moisture. I'd actually suggest an air compressor, or a duster made specifically for computers.
 
You clean the old thermal paste with rubbing alcohol(90% alcohol recommended) and a paper towel. You just apply a little bit to the paper towel and apply it to the old thermal paste. Once you clean the thermal paste, let the surfaces dry out, and apply the new thermal paste. The usual method of applying thermal paste is to put a small dot(The size of a cooked rice piece) and applying the heatsink onto the cpu.

Most cans are made with no moisture in the compressed air. Which is the reason why there is no wetness when you spray it upside down to make moisture-less frost(of course that would be a High School prank). When that warmed back up there was no water left over.

I'd still exercise caution when using them. The can we have here at work, even the slightest tilt will cause moisture to form.
 
I've not seen moisture drip from my compressed cans of air. Not even the cans. It might be the manufacturer letting moisture stay in the compressed air in the cans given to you in your work. It also helps to not let the cans be angled to the left, right, up, or down(90 degrees or more will let out the frost out when I tested with a can right now. It felt like it was cold but no moisture).

I personally find that compressed cans of air let out no moisture when used properly.
 
I'm just saying, be careful with them. I have a can of BlowOff Duster here at work, and if you gently turn it upside-down, you can hear some form of liquid sloshing around inside it it.

When cleaning out cases at work, we lay them on their side so we can get a better look at what needs to be dusted out. Unless he's going to be holding a flashlight in one hand and a can of compressed air in the other hand with the case standing upright. I'd be careful.
 
Compressed air near the intake and exhaust ports for the cooling should do the trick.

Plus not saying that speedfan is a bad program but i would not trust its readings on laptops.

That's the problem. You should never use them in more than 45 degree angles.

Full cans = full. You cannot tilt them whatsoever. Unless he has an old can lying around, then it would be better to use an air compressor.

Just saying this for the sake of the safety of his machine.

I think that speedfan is right here because I can feel it gets extremely hot at the top left of the keyboard, I also can't lay it on my lap as it would just scald me.

Sorry for double post but I am on my phone

I don't see your point. I've not seen cans that spray out a million gallons of moisture thank you very much. A compressed can of air is a lot cheaper than buying or renting an air compressor for a person who is only going to use it for 10 minutes. An air compressor is wasted money if it is not used often and is only used to clean his machine. The air it sucks in would not be completely moisture free either.

There is a good disassemble tutorial for his laptop here.

Never. Ever.

Air Compressors can give out ridiculous amounts of water. The cans are much, much better.

I've never seen any moisture from the one we have at work. Or the three we have at my house. Or the rest of the air compressors I've ever used. Can however? Every single one has sprayed out a massive amount of moisture.
 
The evidence you brought is "experience"(It's easy to lie on the internet) and no real evidence to back it up. It's kinda like trusting someone that the used car you bought it from knows problems with the car that he has not told you about so he could get more money from you and secure the sale of the car.

The problem with Air Compressors is humidity. Yeah, use it in a place with constantly dry air and you'll be fine. But the more humid it is, the more the moisture in the air is also compressed, causing water droplets to form. It's a much riskier endeavour. Depending on the pressure it can also cause a lot of static electricity.

While the cans aren't perfect, in my opinion they're a safer option, and always filled with dry air. But also remember that moisture accumulates under pressure over time so make sure the can of air is new. (Perhaps you were using old cans, which doesn't surprise me, as a lot of PC retailers will leave cans on the shelves for months on end)
 
A can is never COMPLETELY full. Buy a 2L can of Coke. Is it filled to the max? No.

Also, EVERYWHERE on Google says to NOT tilt the can. Just search "Compressed air can tilt"

I proved a point. You just don't seem to get it. You probably never will because you're too thick-headed to get it.

You are just rude. I think it is about time someone washed your mouth with some soap.
 
Buy a compressor, its worth it, plus it can be useful for other duties around the house TRUST ME. They sell compressors that range in all sizes you'll be amazed by the small ones. For moisture buy a water separator, find them cheap on ebay, they snap right on to the hose. Change your heatsink paste too, that helps alot. Got more cash? Buy a laptop cooling stand :sly:.
 
Assuming it's out of warranty, open it up and repaste the heatsink to the CPU and graphics chip with high-quality thermal paste (I recommend Arctic Silver 5). In conjunction with blowing any dust out of the HSF, if that doesn't make it run cooler pretty much nothing short of sitting it on a block of dry ice is going to help.
 
What I would do is clean out the fans and vents using a microfiber cloth (as long as its not damp you should be fine) and buy a laptop fan. They slide under your laptop and blow cool air towards the underside of your computer. They make really great cheap ones, the one I'm using to cool off my PS3 I got from FiveBelow. (You guess how much it cost.) Heck, for $10 you could buy two and keep your laptop as cool as an ice cube. But even if you can't find one for $5, you could easily buy one for $15-$20 at Best Buy.
