I wonder...
Would this prove useful for everyone?

I'm thinking of posting some pictures on how to making the fan on the heatsink turns in the maximum speed...

This thread is only for those fans that uses the 3pin / 4pin that must be connected to the motherboard fan pin...

It's a simple modification yet, it's very useful for everyone...

I'm done with editing, posting it now...

Just post it and then everyone could review it and post their opinion

Step 1)
Knowing your 3 Pin Female Fan Molex

I've state it as Pin1, Pin2, and Pin3

Take a look at the picture:
Side Closeup
[attachmentid=117190]

Top Closeup
[attachmentid=117191]

Take note that there are alot of fan manufacturers that uses different kind of wire colors, so don't remember by the color, remember it by the position...

Just make sure that when u look at the top of the fan molex, u see the 2 plastic lock (The one that is on the left and the right)

Remember which pin is number 1, 2 and 3

Do not make mistakes...

Step 2
Knowing your motherboard 3 Pin Male header...

Normally, you would put it like this, but remember that by doing this, you would not get the highest speed for your fans and some motheboard stop the fans from operating...
[attachmentid=117174]

Take a look at the picture, this board is a socket 478 board, so it'll be using 3 Pin fans...
[attachmentid=117175]

Step 3

Knowing your PSU molex wires...

I will not type a lot of things here...
Just look at the picture and you will understand it by yourself...

[attachmentid=117176]
[attachmentid=117177]

Step 4)

Taking out the 2 pins (+Ve [Positive] Wire & the -Ve [Negative Wire]) from the fan molex connecter...

Take note please, just take out the pin 1 and pin 2...
Leave the pin 3 on the molex as the pin 3 is used for Speed Sensoring...

For this step, u need to use a sharp tools such as a small flat screwdriver as seen in the picture...
**Becareful with sharp items, it could harm you***

a) Push the pin 1 lock
[attachmentid=117179]

b) Push the pin 2 lock
[attachmentid=117180]

Then, this is what you'll get:
**Remember which wire is the pin 1 and which is pin 2...** <-- Important!!!
[attachmentid=117181]

Step 5

Putting the pulled out pin 1 and pin 2 into the Female PSU molex connector

You have two choices here, either to maxed out your fan speed, or to make your fan silence...

Remember which wire on the molex psu is the 12 volts or 5 volts?
Well if you don't this is the easiest way to recognise it:

Yellow Wire on PSU female molex connecter : +VE Positive 12Volts

Red Wire on PSU female molex connecter : +VE Positive 5Volts

Two Black Wire on PSU female molex connecter : -VE Negative

Choice 1) [Full speed 24/7]
Put the Pin 2 into the Yellow wire PSU molex hole and put the Pin 2 into any Black wire PSU molex hole...
[attachmentid=117192]

Choice 2) [Low Speed @ Low Noise 24/7]
Put the Pin 2 into the Red wire PSU molex hole and put the Pin 2 into any Black wire PSU molex hole...
[attachmentid=117193]

Final Step

Putting the FAN female molex connecter to the motherboard male 3 pin header...

Do as what you've seen in the picture...
This is important so you could now how fast your fan is operating...

[attachmentid=117184]

The end of the modification would look like this:

[attachmentid=117185]

Done!!!

Plug directly into the psu kau tim already wat.

yup i'd very interested to learn

but then the fan would spin at the max speed plus the noise would be unbearable....

If you have 3-pin connector and you connect to the 4-pin on mainboard you get full speed all the time right? I see some HSF box description got write it as "foolproof" intheir specs

tot using controller better than direct plug to PSU??

Actually I don't really know what's the purpose of this also.... I don't want my fan to run full speed.....I wanna run fanless if I can.

For everthing else....there's always tornadoes and focus flows.

There, I'm done with my tips on how to maxed out to reach maximum speed and highest CFM out of your fan or how to slow your fan speed so it would be less noisy...

Any comments is much appreciated!!!

Chiao!!!

This time, i only post out on how to maxed out those fan with 3 pin...
For those 4 pins fans users, please wait for a while as i have a lot of things to do now...

Really sorry for the delay of the 4 pin fans speed modifications...

This thread is useful for those that wanna learn sth new.
Shawty, maybe u can include a guide to add a variable fan speed controller for us when u have time

Ahahaha...
The problem is, i didn't even know how to make that so called "Variable fan speed controller"

Maybe i'll ask my brother to built one and later on will post it in this thread on how to do it...

Or should i copyright it so no one could steal our design?
Muahahaha...

Just kidding... i'll ask him to do it later on...

if i wanted to make articles like this, i think i'm gonna take up a lot of space......

bro, you still got a long way to go

and btw, make sure that the header to the molex stays there or else they might cause a short in the PSU

Thanks for your comment...
Just trying to help those newbies in computerisation <--- [I don't even know what's the meaning of that word]

question here: is the mobo fan connector already provide 12v?

yes it provides 12v too, but the mobo fan connector limits the voltage supplied to the fan, therefore not fully utilizing the fan (max out ).

I think ... anyone can help out ??

The only way to do that is to connect the fan wires to the PSU molex...
Through it, you'll get the maximum speed 24hours a day...

But, that if you can only bear the noise..

i think u mean psu can supply more current than the mobo right?

well if the noise get annoying jz turn up the speaker volume

Like that also can...hahahahah...
That's a lil insecure dun ya think? Suddenly one wire falls off and u'll get a fried cpu..hahahha

Better still...just use some spare molex connectors and make a dongle so you can plug the fan onto 12V, 7V or 5V
