This video from 10 years ago saved my life. I found like 35 fans in the garbage, all working, but most of them were 3 pin fan with thermal control. Now I can implement them in new projects.
Interesting video.. I like how the fan had the thermsistor mounted right on the side of the fan (nice and simple). I don't recommend removing this as the life of the fan will go down substantially, but if you decided to, you should also solder the leads for better electrical connection.
Hi, i have an Sensflow EFC0912BF 4W022 with the same thermistor on it, the idea is take off the thermistor and put a potentiometer, the thermistor make 10K ohms on freezer very good for slow speed, so put the 10K pots for variable speed.
If your fairly sure of your soldering skills, I recommend soldering two wires onto the leads of the thermistor & then to a switch. I modified a few of these with switches so I could go from thermal control to full speed when needed. Saves the thermistor & adds another level of control :)
nice tutorial,i have intel stock cooler PWM oem- foxconn and delta both work but after cut the senzor(termostat) is not necessary to stick both wire is work to full speed without stick...is necesarry stick?
My girlfriend calls it hoarding, but I'd like to imagine on a long enough timeline, I'd eventually put to use all these perfectly good parts. My life looks like your shelf.
others have said switches but off = unplug the usb... personally i like to wire control knobs in so i can adjust the speed when i start gaming or on hot days in general.
@CubeComputerChannel would it not be easier and more easily reversible to place a small piece of copper wire between the two poles of the thermistor? It would still bypass it, until you removed it.
I have a ksb06105hb fan from ebay because it looks pretty good and it is a 5v fan, 0.50a. It has 4wires en i can see a ic with 8/10 connections but no thermistor, can i bypass this one?
I have a problem . I have a PC Fan with 3-pin connector. I would like use this Fan on maximal speed but I can use only 2-pin. Can I combinate Tach with plus or minus ?
To anyone commenting about how to bypass a fan with no thermistor, you don't need to bypass the thermistor, as there is no thermistor to bypass. If you want the fan to run at full speed, change your BIOS settings to disable smart fan control.
Great informative video! I have one issue with my fan is keep going on max speed, I am not sure if the thermal burst! but how can I let the fan work again as normal get fast when the CPU gets hot?
pro-tip. if you have an exposed thermoresistor you can just bridge it with a bread tie and snip that off without modifying your fan. while this technique is valid its also over kill. unless you want to hook up your fan to a dedicated (compatible) temperature controller there isn't much need for this mod. other wise you'd need to balance your fan duty cycle to prevent it from burning out withing a year or two of use...
Hello, i would be really happy if you could hellp me. i have a case fan with a thermistor(i use it as a cooler for an old graphic card) that automatically speeds up the fan. I want the fan to be as quiet as possible so i want to reduce the fan speed. is there a way to manipulate the thermistor to make the fan run slower?
If you can determine the resistance value of the thermistor at a given temperature by desoldering the thermistor from the fan and measuring its value with a multimeter, you can replace it with an extension wire with a potentiometer (rheostat) of similar resistance to the thermistor, and be able to control the fan speed.
Hi, thanks for making and sharing this video. Can anyone give me some advice on how to wire a case fan to mains supply. I have an ARTIC F8 PWM PST CO DC 12V 0.09A case fan with three strands of wire attached. Thanks
If you are referring to 120/240V mains, you would need at least a simple plug-in AC adapter that can supply 12V DC 0.09A. If you want the fan to run slower, you can choose a power supply down to 5V DC.
My 48v bldc fan stop working 5 mins after started running. It stopped automatically for a few second and then start running. Could you plz tell me how I can fix it .🙏
I used mine to build a small marijuana grow box, the grow box is strictly for pollinating new strains so now I dont have to risk crossing stuff in my flower room that I dont want crossed and when I'm done breeding I can grow those seeds in the box also. I left the temp chip on my fans so as it gets hotter in the room they push more air but looking back I should have bypassed it
hi..... i have a sheen cpu cooler fan DC FAN 12V .... which is not having that blue coloured something...... It blows very slowly....tell me any idea to speed it... Please!!!!!!!!!
In my opinion, thermistor is resistor that take affect with temperature. Maybe if you replace the thermistor with variable resistor it can be done like that.
Where can I buy. I'm looking for a thermally control fan (about 7 x7cm) with a USB connection no more than 5v 3.1A. I'm in Australia to cool down my over heating Dual Car Dash Camera Video Recorder with GPS
If you wanted to keep the thermal switch you could just run a small bread tie wire around those two leads , twist it up , and cut the excess off. Just keep it out of the fan.
OK, time for the smart-ass reply. If you are just twisting the ends together anyway? Why don't you just grip the thermistor with the pliers and twist it? Cutting the thermistor off doesn't seem to add anything to the finished modification?
@@yangexue6596 - you missed Robert Kubrick's point. The snipping was not necessary. He could have just grabbed onto the thermistor and twisted it until the legs touched. Snipping it off was not needed. It would be bypassed by the short. He could also have just left it alone, untwisted, unsnipped, and wrapped the thermistor's little legs together with some fine, stranded, insulation-free wire, just like a cowboy in a rodeo calf-roping event. Be sure to raise both hands high in the air as soon as you finish, though, so the rodeo judges know to stop the timer!
@@yangexue6596 no you can't, there are no leads left on it this way to be able to do anything else with it. If you could open the fan up, and remove it properly, yes you could. This is not how I'd want to do anything. That will NEVER last, at least solder it.
Ther*mis*tor thermistor. Thermostats use bimetallic switches to open or close a contact, thermistors, which is in fact what this is, use changes in conductivity relative to temperature to vary resistance. Ther mis tor... STOP trying to correct people when YOU are the one who needs correcting. YOU are why there is so much disinformation, stop spreading your ignorance as fact.
@@CubeComputerChannel is there any other way for speeding up the fan which is more easy? Because my fan is not thermal controlled it is stock cooler And this included KMEX Bruhless DC fan DC: 12 volts Ampere: 0.18 amps
It would have been easiest to just add a blob of solder between the two leads. And if I wanted to remove the modification, just reheat and remove the solder.
Usually if you don't see a thermistor on the side of the motor, the fan is not thermally controlled. Many motherboards (especially in OEM brand systems) have smart fan control built in, which throttles down the fan speed.
NIce; you really **don't** need to clip the thermistor off; just solder a thin wire over the 2 legs,leave the thermistor on as it was; you will understand when you study the matter; plus,,it's reversible,any time after that you can remove the *jumper* and the thermistor is as good as it always was ; (i thought i would try to simplify the procedure this way).
there wont be smoke if both of the battery red terminals and black terminals are connected separately not positive and negitive to give it 18 volts that is bad for the fan and it can kill it
just twist a wire around the thermo resistor to bypass it. Once there is a short created, the electricity will be moving along the short, so its pointless to do any extra steps like cutting off the thermo resistor then twisting the metal. Also, what if you break a wire while twisting it? what if you cut too much metal off? Then you can't twist it or tie a wire to it.
I really wish USB fans and laptop coolers were thermally controlled, I end up having to use a thermister in a box that turns the fans on and off. it's kinda lame.

Hook up potentiometer to the thermistor wires and there you go a variable speed fan

I have changed my ups fan but the new fan creating extraordinary noise and also running at high speed RPM... Can we fix this issue
Of course it does make sense cuz it will act like speed controller
Thank you bro, Its working
I also have thousands of cooling fans of different styles in stock, but my video is not as wonderful as yours. Good Job！
That worked for me!!!!!!!!!!!!!!!!!!!!!! THANKS DUDE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

If you did this, then you have to undo whatever you did. Thought that'd be pretty obvious.
I couldnt find this kind of exposed thermistors on any fan that i came across. Is there any other technology..?

either cool the thermistor, or replace it with a different resistor of higher resistance (a variable resitor would probably be best)

Well you could use speed fan or msi after burner if your a pc gamer
One more thing i want to know is, if i remove the transistor, how much voltage this fan will use and that 9V battery will last how long?
That uses more than 1 amp so it wouldn't last long
thnks
Dam now I finally finish my invention
Which computer models come with that type of fan??
The cheap ones.I got one of these and all of them got only in a cheap
Is there a way to control the speed instead of clipping the thermsistor? I’m powering my fan from a ac/dc wall socket.
In my opinion, thermistor is resistor that take affect with temperature. Maybe if you replace the thermistor with variable resistor it can be done like that.
I will try it.i have weaker cooling fans.i need to find a powerful car booster avc fan is rated to 7.2 Amps.
buy an EDF used in model rc jets 😂😂😂😂
@@shutdahellup69420 ok I will buy one when I become rich and famous LOL

you can buy all kind of Computer's fans at www.surplusandparts.com
OMG i have the exact same fan and i want to run it at max speed.
thank god new motherboards has 4 pin PWM headers for controlling RPM of 4 pin fans.. no thermistors needed anymore.
And how about if my fan haven't yet a thermistor
Wow I have the same fan as you haha
How can i open the fan completely
Is it a blowie matron now?

oh and i have a idea insted of braking it brige it so if you whant it heat controlled its not reatach it -.-

Thx bud
Could have just bypassed it but thanks for the video.
nice
But if I use only the thermal energy as the main source would it be easy to make the current speed of fan develops
More higher
Ok so its beem 9 year old video but still helps me
what about connecting a variable resistor with which we can adjust its rpm ?
+Chamjisky Khan That can be done as well.
A Vantec Tornado 80x38mm @ .79Amps is still louder LOL (5700 RPM 84.1 CFM)
Won’t that burn the fan?
i don't have a thermistor on my Foxconn fan the rated stuff is:

I think you could make this a lot easier if you just grabbed a piece of thin wire and wrapped it around the thermistor.

do you know how to do that for a fan that does not have one of those

so is there any way to speed it up then
Yes more voltage.
but dont plug it in your USB an USB is only 5 volts try to find a way to run it at 12 volts
cut the blue wire
I always see 3 or 4 wires, but I've never seen any thermistor on these.
where is thermistor in 120mm fans?

what will happen of I connect 2 9v batteries to it
You might notice a hint of a burning smell and see some smoke.
there wont be smoke if both of the battery red terminals and black terminals are connected separately not positive and negitive to give it 18 volts that is bad for the fan and it can kill it

I thought he was never gona stop twisting those wires together
Probably his first time modifying components in a risky way, I have had my fair share of heartaches from damaging things I try to make better.
well isent a stress controller a better idea
the disliked this video are those who don't have the same product like you. because the pin maybe... on that fan...
maybe
why add a switch when you could add a knob to twist the speed high low much easier and then you can set to your desire
Dan Madden A proper rated rheostat will work in place of the thermistor.
