Mine has a mesh filter, it just makes things worse because it clogs easier. If you haven't cleaned it then you should get on that because you don't want a layer of muck clogging the heatsink causing you to disassemble it.

That was me. The nylon mesh is open enough to allow air to pass through but fine enough to stop most contaminants. But you have to stretch it out so the mesh opens up a little.
I was married twice so had a lot of hose material to experiment on.

Tent repair tape is better. It's a lot more sticky and weather resistant to boot. And it comes in black which blends in with most cases.
Tape down one side then on the opposite side attach the tape to the hose material. Give it a gentle stretching and press the tape down on the case. Attach the tape to one side and do the same. Then the other side.

I think its because I upgraded my laptop from a c2d t7250 @ 2ghz to a c2e x7900 @ 2.8ghz. The laptop fan isn't powerful enough to cool the cpu. My cpu temp goes around 80C when its on a table so thats what I'll do. It doesn't matter anyway, I'm gonna stop using this laptop when I finish my gaming build.

Both EDS from canned air and static from a vac are extremely overstated and over argued. The simple fact being people have done it for years without issue. If I feel safe enough to hold a Titan X and clean it with my shop vac using the bristle end then some dudes cleaning the plastic (which isn't conductive) of his laptop will be of no issue. To toss more fuel on the fire, each place I've worked tech support at had a 3M electronic vac which is comprised of the same materials of a regular shop vac you can get from Walmart.

Now for the people recommending laptop coolers, this can actually cause issues with direction of flow and air pressure. The best thing anybody can do is raise the laptop up for a completely unobstructed flow of air. That is unless the laptop cooler itself has a decent fan with no blockage aimed directly at the intake passage of the laptop. For instance the CM unit linked is decent, but those 2 small fans are directly in the center where most all laptop fans aren't. The grill is like putting a metal grill in front of a case fan. The laptop may be raised, but it still has obstruction of flow. My advice to anybody using a laptop for heavy tasks would be to use your power brick to lift the back end of the device up. Most larger laptops have extruding batteries in the rear you can use to prop on the power brick. If this isn't possible then you can use 2 litre caps to raise the rear end as long as they aren't block the air vents.

Another thing to think about is after a year or so the tiny laptop heatsinks can get up to an inch or more layer of dust build up that almost completely blocks all air flow. The only way to resolve this is take the thing apart and remove the layer of build up.
You should never use a vacuum cleaner to get dust out of a computer in general. You can just buy a $6 can of compressed air and use that to get the dust out. That is a much more simple and safer way. Even if you have not gotten shocked before you shouldn't risk it.

As soon as possible I turned off my laptop and waited several minutes and then started it up again. I opened up speedfan again and it said the cpu was running @ 50C approx. but then it just jumped to 90/100C for a bit but then went down to 70C and back to 50C and this kept on happening. I thought it was just a reading error so I tried HWmonitor but that was giving the same kind of readings! ATM I'm writing this, my cpu is at 74C!
If your CPU is getting that hot, then you may want to replace the heat sink or replace the thermal paste, or both. If neither works, you may need a new processor/CPU(I doubt you will need new CPU though).

It's a laptop mate .

He upgraded to a CPU that takes more power, thus producing more heat as well.
