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... This post has been edited by sHawTY: Jun 27 2006, 01:15 PM |

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!!!

QUOTE(Li[Q]uiD @ Jun 27 2006, 01:26 PM) This thread is useful for those that wanna learn sth new. Ahahaha...Shawty, maybe u can include a guide to add a variable fan speed controller for us when u have time   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... |

Thanks for your comment...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 Just trying to help those newbies in computerisation <--- [I don't even know what's the meaning of that word] This post has been edited by sHawTY: Jun 27 2006, 10:07 PM |

QUOTE(zahri @ Jun 28 2006, 01:23 AM) 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 ). The only way to do that is to connect the fan wires to the PSU molex...I think ... anyone can help out ?? Through it, you'll get the maximum speed 24hours a day... But, that if you can only bear the noise.. |

QUOTE(sniper on the roof @ Jun 28 2006, 11:02 AM) Like that also can...hahahahah... 7 Volts setting? 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   I just learn that today... |

QUOTE(sniper on the roof @ Jun 28 2006, 05:45 PM) Actually there's no real benefit of getting the fan run that lil bit extra. A few extra rpm wouldn't make any difference. Besides, most fans are spec'ed to run at +/- 10% of the stated rpm. Uhhh...Who says so man? My Hyper 6+ , runs at motherboard ranged speed = 42celcius... when set to highest speed = 40celcius... Who says it won't make any difference? Even if the difference is low, it does make a little difference in the temperature... Uhh... Why are u trying to ruin this thread? |

QUOTE(sniper on the roof @ Jun 28 2006, 11:04 PM) Just wanna clarify.. ur siggy says ur using a Hyper 6+ with the 4pin connector. How come the pics are using standard 3pin females? Hahaha...Also found the reason why there such a big temp difference. Ur 100mm Hyper6 fan is pwm controlled (4pin) so when plugged directly into the mobo header, it'll just run at it slowest speed at 1800rpm And you could short them to run them full speed at 3600rpm. http://www.coolermaster.com/index.php?LT=e..._ID=RR-UNH-P0U1 Yes, i'm using a hyper 6+... But that doesn't mean i only have one heatsink lying in my room... I have a lot of intel 478 heatsink... The one i'm using for this thread is an ACER OEM heatsink for my oldskool 3.0D processor... |

QUOTE(sniper on the roof @ Jun 28 2006, 11:18 PM) Ok..my last post in this thread ok. Again, my purpose is just to clarify things. Hey sniper, seems like we're two were the only active in this thread...  - My guess is that ur 2C difference is because of the Hyper6+'s 4pin pwm peculiarities which was stated in coolermaster's website. - All the motherboard headers when running without any software intervention outputs 11.XX V which is close enough to 12V. Hence the fan run's at most 10% slower than rated speed. Finally, would be great if everyone could give it a shot and report in on the findings. That'll be cool. Cheers..  |

QUOTE(AllnGap @ Jun 29 2006, 09:11 AM) it's pretty normal for mini fan like 40m ones to have that kind of speed. ........ coz they are used in 1U servers and they must have super pressure..... last time i sold the ones that runs at 13,500rpm. just imagine 40mm fan can give 23.5cfm. 40mm give output of 80mm fan, so the rpm must be damn fast |

QUOTE(vey99 @ Jun 29 2006, 11:37 AM) That is so cool man imagine you got LEDs on that, you could house it in transparent case and show ur frens ??? Shawty: Thanks for the fan tip, made me reconsider buying a CM Musketeer (of course thats not the only reason i want one...) If you're going to buy a musketeer, go to ALLIT hypermarket at Lowyatt plaza... That's the shop which offers the lowest price for a CM Musketeer... |

QUOTE(Shah81 @ Jul 15 2006, 06:18 PM) This trick will not work if the fan got a built in temp sensor. Ngiahaha...Want to make your fan spin faster.....splice the -5V from your psu and connect the negative wire from your fan to that -5V line. Bam!!! your fan runs at +17V......  » Click to show Spoiler - click again to hide... « You're funny man... Offcourse the fan would die... Tried that setting before liao... 2 off my fans already died... |
