Fans not spinning

[josh1002]

I have the Deepcool rf120 3in1 fans and when i have my computer off for a while and then turn it on, the fans only light up but don’t spin. I need to spin it with my hand to get them going. Why?

A 12v fan needs more than 5v to start.
Possibly the rgb lighting is draining off too much voltage.

How would that affect it tho because my power supply is more than enough. Also is there a way to fix it?

The startup voltage of the Deepcool RF 120 – 3 in 1 is 7 VDC. Measure the voltage at the fan header when you turn on the system and see if it is at least 7 volts or higher.

Where is the fan connected?
If it is connected directly to a molex connector on the PSU, it should run at full speed always.
More likely, it is connected to a motherboard header.
Look into the bios for fan control settings.
You should want a minimum speed of 500rpm or greater.
If the setting or default is <500 rpm the fan might not start.

MERGED QUESTION
Question from josh1002 : "Fans not spinning on startup"

My Deepcool rf120 3in1 fans are not moving when I turn on my pc. They rotate once then stop and it repeats this. I was told is takes to much power at startup to get them going. Is this because I have the fans plugged into the same SATA cable as my hard drive, are they not moving because it’s putting all the power to the drive?
