Another Question About Fan (Macbook Pro)

Normal.

Your fans will run at 2000 RPM, normal. Your Mac is designed to shut down before you can do any damage.

The fans ALWAYS run. 2000 is the default idle speed.

Another point of contention with many newcomers is "my Mac is HOT". Since many come from owing plastic encased portables, handling these all-metal Macs will feel as much hotter, since the entire chassis is one giant heatsink. But they are chock-full of heat sensors all over that will trigger a shutdown if needed.

At idle, I'd have to stick my ear to the metal to notice them running. Max fan speed I've seen on mine is around 6500 RPM the pair (15" and 17" models have two, 13" just the one). At that point, they are evident and may even be construed as "noisy" in a totally quiet room. But it is a constant and steady hum that fades in the background of regular office noise. If screechy or grinding, may mean that the motor is dust clogged and need to be replaced (sealed motors, not user serviceable). I had that happen to my previous Mac early on, but that's the only time I've had that in the past 4 metal Macs and 12 years.

It's normal that the fans turn on

Noise like that is not normal...get it checked out...most likely dust, & try not to use your Mac while running the fans like that...you don't want to kill your fan.

Lay off the games for now and use the thing for IMPORTANT stuff such as surviving the school year, until serviced.

Fan replacement is, besides the RAM, battery and HDD replacement, one of the least painful and time consuming procedures. On my previous MBP, got to watch the tech do both in less than 20 minutes. They probably ran out of replacement parts, hence the wait.

Like I said, use the Mac for truly important stuff, given that it is at risk. And if you can't resist the urge to flog it, at least run Temperature Monitor or something so you can check if it is going off the deep end. Probably not too helpful when gaming since they tend to take up the full screen, but whatever... http://www.bresink.de/osx/TemperatureMonitor.html

I mean how long, cant edit coz posting it from an ipad, how long should i use it for gaming maximum?

If it were me, and I needed that computer for school, I would not use it for ANYTHING not absolutely necessary until I could get it fixed. While it does have thermal shutdown fieatures in the firmware that are intended to protect against overheat damage, you would be really pushing your luck to put those to the test on a machine whose temperature control you already know is compromised by the bad fan.

It's like asking how long can I drag race in my car without coolant and the temperature guage just below the red? Can I do it, yes. Should I do it, NO.
