Double Fan

if i put two fans on top of each other, air flow going the same way obviously, would it give more air flow in the case or would it not make any difference. wanted to know because i have a lot of spare fans and nowhere to put them.
 
It'll move more air through the case. Just make sure you also have fresh air coming in, preferably through the front.
 
Of course it will move air through the case, but I don't really think it will make your PC a lot cooler. You could try it and test the temperatures and see if they are any lower, but I don't think it will matter that much.
 
It will move more air, but not double what you would get from one fan due to various reasons.

Completely depends on the current case ventilation. If there were currently only one case fan I think it would make quite a big difference ;)
 
Doubt It :)

I doubt it will perform better. That's beacause the fan on the inside (supposing they are blowing inside the case) would be acting as a obstacle to airflow from the first. Think about it. It will most probably do better by itself rather than two fans on top of each other. I hope I am right...just seems more logical to me.

JAN :D

I understand your logic, but think of it as an electrical equivalent circuit where pressure = voltage, current = airflow, and resistance = well... resistance. A fan can be seen as a battery essentially creating a voltage difference. Putting batteries together in effect increases the voltage. There would be an intermediate pressure in between the fans such as there would be an intermediate pressure between batteries. The additional resistance (as well as the increased airflow leading to a different friction factor... blah blah blah) would make it so it didn't double the airflow.
 
i got 2 fans at the back one on the fornt and one on the side (side and front sucking in, 2 at back blowing out). ill try it anyway see if it makes a difference.
cheers for the help, and you guys reply fast. :)
 
If you use motherboard monitor 5, and see what the temperature is with the case together, try taking the case apart or taking off the sides. You can compare your current temperatures with the maximum lowest temperature by having the case apart. I have a fan on the back of my case, one in the power supply, one on the video card, and one on the cpu, and it sounds as if there is a jet ready to take off in my room. I do not think that it is worth having your computer one degree cooler to have it sound louder. I sure wish that liquid cooling was cheaper and easier to install...
