Eh.... reduce gpu load to reduce temperature? That's retarded. What about other games that use plenty of the gpu? Either get better cooling for your computer case, get a better graphics card, or manually raise the fan speed. On my Powercolor HD5870 PCS+ it's never ever goes above 60C in SC2. When it's really hot outside games like BC2 push it up to 65C. lol Ya, no card has ever burned out by being overloaded. Trying to limit the load, just retarded. My bad. edit: oh Shit! Epic first post BTW.
Reducing the load to lower temps is counterintuitive and generally not the best thing to do. It is only avoiding the problem. If you want lower temps, you should check for dust in your heatsinks, and/or ramp up the fan speed before gaming.

My GPU reach 76°C when i play sc2 and 75°C for the CPUs.
Is it standard?

That's pretty reasonable probably. What GPU & CPU do you have?
|
A Core 2 Duo P7350@2.00Ghz and an NVIDIA GT 240M.

Yeah you're fine. Start worrying around 85 or 90 (90 is listed max operating for P7350).

how do I find GPU temperature?

You can use CPUID HWMonitor it's a freeware.

I have an ATI 4850 and I've never seen the fan working at maximum speed until I started playing sc2.

I cannot begin to tell you the number of problems that result from auto fan speeds. You shouldn't need to hobble you GPU at all. Hell you have a faster card than I do, you should be running ultra HD like I do, no some pussy 60 fps, no offense. pussy 60 fps? You do realize that is quite a bit more than humans eye can register. In other words there is no need to play the game on 120 fps if you can play it on 60.
No matter how many doctors or science professionals tell me this, it doesn't change the fact that I can solidly tell the difference between 60 and 120 FPS. It's not a question of how many frames per second your eyes can register, it's a question of how often the image on the screen is being updated to match what has changed in the game code in the last interval of time. If your eyes only register 20 unique frames each second, then all the more important that those 20 be as up to date as possible. I know I may sound ignorant with that last line, but it's all I can do to tell you it makes a difference, for certain. Playing TF2 with silky smooth buttery 100+ FPS has systemic benefits throughout the user input hardware. Mouse movement feels more responsive because there are more unique time intervals being accurately represented on the screen. Trust me broham! Oh, it's also worth saying that when rendering load increases, you'll experience less noticeable "lags" or stuttering if your default FPS is high enough that stutters are only dropping you into the 60s.

My laptop Geforce 240M gets up to 80c while running Starcraft 2.

Vsync synchronizes the framerate provided by the GPU to the refresh rate of your monitor. If you are above 60FPS, you will go to 60FPS, and if you are between 30-60FPS, you go to 30FPS.
If you are over the refresh rate of your monitor, it is capped at the refresh rate of your monitor. However, if you are "between 30-60 FPS" , you will most certainly not "go to 30 FPS", that's quite incorrect.
Each time a frame is ready to be rendered, it simply waits for the next monitor refresh cycle (instead of rendering it immediately, which would result in "Tearing")

This is entirely 100% correct, and it makes me really miss using my old CRT for gaming

Why? CRTs refresh at about 17ms, and most LCD screens these days are 5ms (there are 2ms as well). It really doesn't matter anymore. Before these new screens, though....LCDs were awful for games. Especially games where you need to be frameperfect (fighters) to do things.

Where did you come up with that number?
CRT's could quite easily do 120 Hz, some did 150 Hz and even higher, so your quote about 17ms CRT response time is not correct.
The response time in milliseconds that LCD manufacturers give today are pretty much useless. They represent the best possible scenario, and only a Gray-to-Gray transition (not black-white-black , or others for example)
Manufacturers pretty much lie (greatly exaggerate) the LCD response times in much the same way as the escalating "Contrast Ratio" Wars (some are claiming infinity now!)

I vacuum and clean the inside of my computer regularly :D
Also, I make sure the air flow goes right over the top of the cards and all in 1 direction like it's supposed to.
My processor fan is sweet- but idk wtf is going on inside the GTX260... its all covered up...
+ Show Spoiler +
I'll assume everything is going to plan in there o.o

I hope your using a proper low power vacuum, else i just use compressed air.

Vsync uses a rule which essentially dictates that the back buffer can't go to the frame buffer until immediately after a refresh.
So if you are capable of getting 45 FPS on a 60Hz monitor, then every time the monitor refreshes, you draw 3/4th of the picture, but you can't display that picture because it isn't complete, so the monitor is forced to wait.
So monitor is refreshed, it grabs 1 frame. Everything is ok, but then the GPU is only capable of drawing 3/4th of the frame, so the monitor refreshes and nothing is done. So far, 2 refreshes, 1 frame drawn. Then it finishes drawing the second frame, and the monitor refreshes, displaying the second frame, and drawing 3/4th of the 3rd frame. It refreshes and nothing is changed because the 3rd frame isn't complete. So far, 4 refreshes, 2 frames. And this process repeats itself.
Vsync is a relic from the days of CRT anyways. Not sure why anyone would ever use it

Didn't see anyone delve into this so I'd add that the most common problem I've had with video cards overheating was due to the fan speed. Most of these newer cards today will not run at 100% fan speed which they really should when they're being heavily taxed.
I've had serious issues specifically with some semi-recent Nvidia cards not speeding up the fan at all regardless of temperature or gpu utilization. Even using the application supplied by Nvidia drivers to control the fan speed manually wouldn't work properly and would take the speed right back to the default 30%. (This was a driver issue in XP-64bit for specific boards which they never fixed.) The following programs should suffice to keep you aware and in control of your video card.
EVGA Precision - pretty certain this will work with non-evga cards to control and monitor fan speed and temperatures.
Riva Tuner {fanspeed guide}- should do the same as the above but its a little more convoluted I would caution not to mess with anything you don't understand.
MSI Afterburner - I currently use this in my ati 5770, its a very nice interface and keeps a constant graph going of all the stats you should need for your card. I'm just not certain it'll work with all brands of cards.
The point that needs to be driven home though is to always keep an eye on both your fan speed and gpu temperature in any game (excluding brood war of course  ).
