How many case fans can i have?

post #1 of 11
Thread Starter 
I am not entirely sure, but my case came with 2 fans already, but I got 2 other extra fans to improve air flow, however now I'm not certain that I can connect them to either PSU or mobo...I'm not sure tho, can anyone help with this and tell me if my PSU + mobo allows me to have more than 2 case fans? Thanks

Its all good. If your mobo doesn't have 4 connectors just get an adapter.

Well, it looks like your motherboard has only 2 fans headers. If your fans has the molex connector you can connect them in your PSU with no problem though they will run at max speed all the time.

If they have a 3 pin header then you can put them in your mobo and also you can control the speed of the fans.

This is a molex fan and you put it in your PSU:



This is a 3 pin fan and you put it in your mobo:

the fan came with a 3 pin to 4 pin adaptor if thats what you mean? But i can't see an unused cable from the PSU to connect it to tho? The unused cables are labelled HDD or DVD or something or other... thanks

As much as you want and depends on your case too.

lanboy air can have up to 15 fans.

It's listed in your manual,

But you have (1) 4 Pin CPU fan connector, and one 3 pin on your motherboard.

You can add as many fans as you like. If your 3 pin on the motherboard is not being used, and your extra fan has a 3 pin, you can plug it in there when the power is off, Power Supply unplugged. Now, if it's not available, you can plug them into a 4 pin molex. If your fans do not have a molex connector; you can get a 3 pin fan to molex converter, or even a fan controller. The fan controller will allow you to change the speed of the fans connected to it, run quieter, or better performance (louder)

Your PSU has 4 molex connectors so you can use those.

Search for a cable looking like this one:

If your power hasnt free 4 pin connector use 3 pin fans and conncet them to your mb.Your mb have at least 3 three pin connector.

Q: How many case fans?
A: The PSU is the limit and i will tell you why.

Firstly you will use the 3 PIN headers (consult your mobo manual to locate them and be advised the 4 pin header is mainly for the CPU if the CPU cooler fan is PWM).

After you run out of fan headers you will resort to the PSU Molex connectors, that's why i said the PSU is the limit. Fans that are powered up by the PSU will run all the time at 100% speed (unless they are some fancy ones which come with an incorporated fan controller).

From a quick glance of your PSU specs i noticed you have 4 Molex connectors?
Cable Connectors
ATX 12V 24-Pin 1X
4-Pin Molex (HDD) 4x
4-Pin Floppy (FDD) 1x
SATA 5x
4-Pin 12V 1x
6+2-Pin PCI-Express 2x
8-Pin 12V 1x

So mobo headers + PSU Molex connectors = maximum amount of fans.

But ofc the case can be a limit as well, it will probably support less fans than your max amount of fans that can be powered up. BUT you can always do a mod of your case and drill holes/cut-outs for extra fans if your so desperate.

PS: i didn't mention fan controllers since i never used them, they might extend the number of fans, i frankly don't know.

PPS: If you actually check your motherboard manual (on page 8) you will se the number and locations of fan headers.
http://www.asus.com/product.aspx?P_I...NvL&templete=2

I checked it and you have 1 x 4 PIN CPU fan header and 1 x 3 PIN chassis fan header located on center left side of the mobo. At first glance this is all i spotted. Pretty weak, my 88TD-V EVO also has only 2 chassis headers plus one 4 pin CPU fan header. AM3 mobos don't seem to get much fan love, pwn intended.
