Should I add more cooling?

I am always thinking when it come to cooling a computer the more the better. It would seem I have enough fans but I would like to add a couple more. I have 7 expansion slot's on the rear and 3 empty slots below the DVD ROM on the front. I would like to add 1 to the front and 1 to the rear.

The front to pull and the rear to push the air. Do I need to do this or is it just fine the way it came from the factory? After looking at the fans where does one plug them in to get power to them?

Just so you know i'm the type of guy who always added the external automatic transmission cooler just to be on the safe side. For $50 it was cheap insurance and they worked. So what are my options here? Thanks for your input! It's always appreciated. John
 
can you post a link to your case so we can see what you have for airflow options?

Just to address the push pull question. I would recommend having a push pull system it really helps.
 
It depends on your system hardware. If it is overheating then you should, if it is not, you can but you do not have to.
 


Here is what my case look's like. The other side of the case does not have any opening's/fan's. I was thinking of adding a pull fan in one of the empty slot's below the DVD ROM. I will admit that when I open the case there is ample room for air to circulate. Is there a certain maximum temp that the inside of the case should be? Thanks!
 
Best to keep a slightly higher intake than exhaust. So if you only have an exhaust fan, then get either one or two intake fans.
 
What's the best intake fan that would fit in one of the empty slot's below the DVD-Rom? And where would you plug it in to get power to it?
 
You don't put fans in 5.25" Expansion bays (where the CD/DVD drives go if that's what you're talking about)

A good intake fan would probably be this one http://www.newegg.com/Product/Product.aspx?Item=N82E16835103061&cm_re=r4-_-35-103-061-_-Product as it's pretty quiet, has good airflow, and doesn't have an LED (an LED would probably make your PC look weird)

If you want LEDs, look at these fans: http://www.newegg.com/Product/Produ... 1372926569&Description=r4&name=2000-2499 RPM

If you have a molex connector, those'd work if you plug the fans into the wire adapter.

That'd come directly from your power supply.

If your motherboard has a 3 or 4 pin fan header, then you can plug the fan into that without any adapter. If the motherboard has a different amount of pins than your wire has sockets, you're still okay, you just have to make sure you align the plastic slot on the back of the fan wire to the piece coming up from the fan header.

I was told (depending on size of the fans) to have 2 in for every 1 out. Don't know where he gots his info from, but he's a computer engineer, so I tend to listen to him.:P

That doesn't make sense(for the dust part) wouldn't this mean more fresh air with dust in it to build up?

Don't take my word for this answer, but it's an attempt.

My guess is that is has something to do with air pressure. Higher air pressure probably keeps dust floating around in the case and then allows it to eventually exit the case via an exhaust fan.

Lower air pressure probably lets the dust fall to the bottom of the case or into coolers or video cards.

That doesn't really make sense. To keep dust floating in the air you want more air movement, pressure won't make a difference.

However, high or low pressure does determine which direction air is moving at vent holes or other non-air tight spots with no fans.

If most people say that it's better to have higher pressure, that's to make sure that heat is leaving these vents/cracks.

It makes sense that it doesn't make sense, as I haven't studied anything concerning air pressures quite yet.

Ahh. I see. So if there is negative air pressure in the case, then unfiltered air would be sucked from outside of the case into the case, thus collecting more dust?
 
Basically, having more air going in than out keeps the air curculating until the exhaust fan can remove it, rather than it settling (along with the dust)

I need to get at leats 2 more fans to have that sort of setup. that's what the mounts on my side panel are for :D
