Web i needed to know if it's possible to hook up or wire and old computer fan with red black and white wire to a new fan with a black red and yellow wire.

Fan yellow wire. Web blue and yellow wires are used in ceiling fans. Web i can't seem to find what kind of signal is sent through a fan's yellow wire. I have an old motherboard that uses the old black red and white three pin connector and i want to use a smaller fan that's newer but has black yellow and red wiring.

What is the yellow wire for on a computer fan? On both, the black wire is ground, and the red wire is the + dc voltage supply. Discover the different color codes and their corresponding functions for the fan's power, ground, pwm, and tachometer wires.

Sometimes it is 1:1 and one period output on the tach line is equal to one revolution of the fan; If i have a case fan with 3 wires to connect to the mainboard and the yellow wire is the one intended to controll the fan speed, will the fan always go 100% speed if i just cut the yellow wire and connect it's connector to mainboard? Web answer (1 of 4):

Web in the ceiling box where the fan is installed, there are: Web 1 bldc = brushless dc (i find this abbreviation uncommon) feb 1, 2013 at 1:06 add a comment 2 answers sorted by: With the fan spinning at 6000 rpm, you would measure a 200 hz pulse rate (6000 rev/min / 60 s *.

If you have a ceiling fan, you will need to connect the hot wire to one of the outlets on the fan. I don't want the fan to have speed less than its 100%. Web connect the green / yellow wire as ground wire from the fan to the household earth wire.

It is similar to pwm output but it is the frequency that is related to rotation of the fan. Thanks to fuggetaboudit, i did some more research, and the pinout, i'd guess, is: *cable coloring varies from fan to fan.
