Compatible Computer Case Fan?

Hi, I searched ALL over google and I havent found, how to find a compatible system case fan! So, my question is, can I use any system fan that I purchase? Or does it have to be specific, if it does, can you tell me how I can find out if a fan on the internet is compatible to my computer at home? I have a dell inspiron 531.

Processor: AMD 64 X2 Athlon 3800+ going to upgrade to AMD 64 X2 Athlon 5800+ AM2 Socket.

RAM: 2 GB

Motherboard: Model 0RY206
Dell Inspiron 531

Power Supply: 300W

Fans: 3

Fan 1 (processor): 1650-1750RPM I never saw it go any higher than that.

Fan 2 (not sure if it's case fan or graphic card fan): 1000-1100RPM

Fan 3: 0 RPM

I used Speed Fan to aquire this info

Graphic Card: NVIDIA GeForce GT240 1 GB.

Temperature of CPU: 40-54 Celsius. above 50 Celsius if playing game. Below 50 Celcius if just browsing internet.

Just make sure the fan fits on your computer and make sure when you put it in your computer make it blow air out of your computer or it will just circulate hot air in your computer and make it over heat.

What kind of processor do you have?
The fan on my processor spins around 4000 RPM (rotations per minute) and I got an Intel Pentium 4, 3.4ghz processor. The fan on my case spins around 2000 RPM.

I can give you a good guess of what kind of fan you should get.
But I need to know all about your computer like-

processor?
ram?
motherboard?
power supply?
fans currently in your computer?
speed of the fans (RPM) you have? (can be found in the bios)
graphics card?
any other cards you have in your computer?
hard drives?

P.S. Don't worry about if it should have a 3 or 2 pin power connector from the fan to your motherboard. Your motherboard should have a 3 pin connector for a fan somewhere on it (it will only have 2 pin connectors on it if its like super ancient like one of those old windows 95 dinosaur computers, which you probably don't have) and the fan you buy should have a 3 pin connector on its cord because thats what computers these days use- they don't sell fans with 2 pin connectors so don't worry about it. Well I think they don't sell them.. people might, but it would be rare to find one and the seller wouldn't tell you.

EDIT: well i have an intel pentium 4, 3.4ghz processor and its fan runs around 4000RPM.. so lol idk about you.. thats a little slow.. and my case fan runs at 2000RPM. My graphics card is a low power consuming 512mb card. And my power supply is 500W. You might have some power shortage problems some time down the road... and your fans are really slow compared to mine. and my computer isnt that great. My processor runs at about 120 degrees F. You either have some major over heating problems or my fans are just a little much for my computer. The fan on the case of my computer is faster than the one on your processor. So you probably have a low power consuming processor that doesnt generate as much heat. And the 2nd fan that you said that you had, it was around like 1000rpm, thats a little slow for a 1gb graphics card. and you said your not sure if its the fan in your case or the fan in your graphics card, so you already have a case fan? so my guess is that your afraid your computer might over heat because of the fan? im not really sure.. about that. I would guess you should buy a fan with an rpm around 2000. but your processors fan doesnt even go that fast.. Im confused, are you sure thats the real speed of your fans? and if so thats really slow for a processor. Also your graphics card is way better than mine, which is 1gb. my graphics card is only 512mb. you have a 300W ps, i have a 500W ps. Do you see whats weird about this? my computer is about normal. And your's I really dont know.

my best guess is to take it to a computer shop and have them take a look at it. Because your computer is weird compared to mine...

Its weird because your graphics card is better than mine but i have a better power supply than you. and the website that i bought mine from said the minimum power supply would be 500W, so you might want to look up that about your power supply and graphics card. And your fans are alot slower than mine, what kind of fans do you have, because thats very strange.

The best thing I think you should get is a 2000RPM fan, its not too expensive, and it wouldn't hurt because your computer would be really cool. And don't forget to make sure your fan blows air out of your computer or else it will just circulate hot air in your computer and make it over heat even more. (also make sure the fans the right size for your case)
