How I fixed my Dell SXPS 1645 throttling

Here is what used to happen:
- Every time I start a game, the fan would kick in at the highest noise level
- Temps would go up very high in 5-10 mins
- As the temps increase, the game would turn into a picture slideshow with GPU throttling
- Using ThrottleStop would just eventually make the computer shutdown itself
- Even while normal surfing (youtube, doc editing, etc.), the temps would go as high as 70 degrees in about 45 mins

Here is how I fixed it:
- Compressed air duster.

- My problem was not with the fan, but the air-vent that is right in front of the screen.
- I placed the duster at an angle on one side of the vent and blew it with compressed air.
- A LOT of dust came out the vent and the fan openings. The fact that I had always opened the back-plate and only cleaned the fan and not the air vent allowed it to be blocked by dust over time. So no matter how hard the fan was working, the heat would never be able to escape from the vent. 2 mins of blowing air into the vent worked like magic.

The results
- After over an hour of playing NBA 2K11, no GPU/CPU throttling whatsoever
- Temperature idles around 50 C (as suggested by other users to be normal)
- Laptop overall seems to be working much faster
- Battery life also seemed to increase by 30 mins or so since the fans aren't kicking in as quickly

I know that this isn't supposed to fix the real throttling that the users are facing and have tried more advanced solutions, but I believe that some of the less experienced users who are having the same problem should try this simple trick out before applying thermal paste, buying expensive laptop cooler, etc. It made the laptop a whole lot bearable for me.

If you guys are interested, let me know and I will post ThrottleStop/benchmarking results.

Please try this out and let us know the results.
