Thermal paste didn't work?

Since I bought this laptop I've had issues with the graphic card hitting extremely high temps. It usually idles at around 70-75C, but while I'm gaming it can hit and has hit 105C. I've never seen it go above that, except once it hit 106C while playing Starcraft 2 on all high settings and since then I've never played the game on high settings because I'm afraid it might fry my graphics card. I understand some graphics cards are built to throttle the amount of usage if it starts to run to hot, but still 105C is EXTREMELY hot.

After getting tired of worrying about the heat, I decided to cut a two inch hole where the fan is and I placed wire mesh over the hole to block dust particles. This did help reduce my temp about 10C, but it's still extremely hot and has been getting hotter lately.

So recently I was playing Diablo 3 at almost max settings and it would stay around 93-95C which isn't bad, but if I'm in a group with like 3-5 people it would hit between 100-105C again. And these are the temps after cutting a hole in the bottom of my laptop. So me of course getting frusterated, I decided to open up the back panel, use a can of compressed air to blow out all the dust from the fan and stuff, and I even applied new thermal paste to the heatsink. Now I'm not sure if I did it right, but I believe I did. The paste came in a tiny (nail polish sized) bottle and there was a brush attached to the cap of it (kind of like nail polish), so I used the brush to gently spread it on the parts where the heatsink make contact with the components. (Graphics card/processor/motherboard/etc...) So I put the heatsink back on and put my computer back together.

Now it idles between 80-90C and I haven't even tried playing a game yet because I'm afraid it might overheat now. I'm not sure what I did. I thought adding new thermal paste would make it run cooler, but instead it made it a lot worse. I honestly don't think I put it on wrong. The only thing I can think, is that the thermal paste I used might be old and "Bad". Like how do you tell if it's no good anymore? I've had it for awhile, but it still seemed ok to me, although it did seem quite watery.

These are the specs of my computer for those of you wondering why my graphics card runs so hot. (It's the only thing in my computer that tends to run extremely hot.) Any help with this would be greatly appreciated.

I like the larger fan because it's not as audible. The smaller fans may make too much noise. I read some...

This is what you should of done, a cooling pad for laptops. I use one and it helps a lot. Try this - http://www.amazon.com/Cooler-Master-NotePal-Ultra-Slim-R9-NBC-XSLI-GP/dp/B005C31HC0/ref=lp_2243862011_1_1?ie=UTF8&qid=1375844858&sr=1-1

Thermal paste that you brush on? That sounds suspicious.

All the remotely good thermal pastes I have ever worked with are much too thick and sticky to spread with a brush. Some even require considerable force just to squeeze it out of its tube.

I don't remember seeing proper thermal paste in a brush-bottle. They all come either in tubes or syringes.

Do you have a link to your alleged thermal paste? I'm thinking whatever you got is not what you thought it was.

Here is a picture of the container and the brush it comes with. It's actually called thermal Grease and I know it should work because the guy who cleaned out my computer and added all the thermal compound before I learned how to do it gave me this bottle. Since he was the one who technically taught me how to do all of this. Although I know thermal paste is supposed to be more a thick consistency and this stuff is like a nail polish consistency so it had me worried. Although I just opened up my laptop again and took the heat sink off. I noticed there wasn't much thermal grease on the heat sink (so I'm assuming there wasn't much contact between the graphics card and the heat sink) So I added a little more to it and made sure the heat sink was properly screwed back in and now my idle temp is 70C and it hits around 95 while playing Diablo 3. At least it's back to what I originally had it at before doing all this, but it's still really hot.

I was thinking about going to Radio Shack tomorrow and purchasing some Arctic Silver 5 thermal paste. I hear it's much better and hopefully it with be of thicker consistency. I'll test that out and let you guys know what happens. Thanks for all the responses so far. I just wanted to say I do have a laptop cooling pad my laptop sits on, so that option is out of question.

From what I can see online, that stuff is supposed to be roughly on par with AS4 so as long as you use it properly, it should get the job done.

If your heatsink has a rough surface, you might have to apply the stuff to both surfaces: the runny stuff might lack the viscosity to work itself into scratches on its own or might be spread too thin to get in.

Well I went to Radioshack today and purchased a tube of Arctic Silver 5 for 12.99$. I took the back panel off of my laptop and cleaned off all of the Zalman Super Thermal Grease with a bunch of Q-tips and rubbing alcohol (Making sure not to get too much rubbing alcohol on the components of the computer. Although I did want to mention this. The old Zalman Super Thermal Grease was still somewhat liquidy. It didn't harden at all from gaming a little bit last night and a tiny bit of it got underneath the plastic covering the top of my processor. I'm not sure if that would harm anything, but right now I'm typing to you on my laptop so it must be ok.

Anyways, I added about a rice sized drop on each one of the components (Graphics Card/Processor/Motherboard). I didn't put any on the heat sink itself this time, although I did do that with the old Zalman Super Thermal Grease. So I made sure my heat sink was properly placed and I screwed it down to secure it. It seems to be idling at 70-80C right now, which once again is still very hot. I know Arctic Silver 5 takes time to settle in as the graphics card heats up and what not, so it might not be showing it's full performance yet.

@boju: I have an Asus G60VX-RBBX05 laptop. I do understand that a 260M in a laptop will run hot because theres not much air space. Although I've always had this graphics card idle around 65-75C and it reaches 90-105C during full load. I honestly can't figure out why it's so hot, but I know my cards not a defect or anything because I did research on the topic for my specific laptop and it seems like everyone with this laptop has the same issue. I just don't understand why it would be so hot with a fresh cleaning/thermal compound replacement. Also I do know the fan is working because I can hear it kick on when the temp reaches a certain point (usually when I'm gaming).

Honestly though, my graphics card is located right underneath the W,A,S,D keys of my laptop and since it gets so hot, while playing a game my hand warms up a ton and it gets frustrating. So lately I've been hooking an extra keyboard up to it so I don't have that problem. I just want to get this solved, I've had this problem for ages now. I was looking into water cooling, but in a laptop I'm not sure that's possible?

Also, to answer your question from before scoobydenon, I do have a laptop cooling pad, but after looking at the one you linked, mine looks shitty as hell. I'm not sure of the RPM's on my fan, but I do know that's a huge factor in keeping your laptop cool. The one you linked me is the 160mm fan that spins at 1500 RPM. I also noticed there were two other types of that laptop cooling pad. There was another that is 140mm and spins at 1500RPM, but there was another one called the x3 thats 200mm, but it's RPM is only adjustable between 500-850RPM. Would the lower amount of RPM making my laptop run hotter than if I were to buy the 160mm fan that runs at 1500rpm? or would it run cooler because it's a larger fan. I just want to make sure I make the right purchase if i do buy a new cooling pad.

Sorry for the multiple posts. The link in my last post was another laptop cooling pad I found with 2 smaller 80mm fans that spin between 950-1800RPM. Although there was another one like this with 3 smaller 80mm fans that spin between 950-1800RPM.

I just want opinions on this since I've never truely looked into the RPM's of the fan and the size of it, i just went to walmart to purchase my current laptop cooling pad. The one I have is the gray one made by Logitech and from what I can tell the fan on that just broke yesterday anyways lol
