View Full Version : 5V rail low. Too many 5V fans?

I have an Antec True Power 480. My 5V rail is at 4.53 V, 12 is at 11.88 and 3 at 3.23. The 12 and 3 are acceptable, but the 5 seems very low. I have 4 5v 80mm panaflos and 1 5v 120mm fan. Do you think all these fans drawing from the 5v rail could lower it so much?

These voltages are all measured with a multi-meter.

Thanks in advance.
Cheer.

p.s. This is what I have in my computer:
Gigabyte 7VRX with Athlon Xp 1600+ @ 2000+
Sapphire 9800 Pro
1 x 80Gb WD
1 x 60Gb Ibm
1 Gb ram
sound, lan etc...

Try unplugging all the fans you don't need and see if the +5 goes up.

Are you sure those fans are 5v? I've rarely seen 5v case fans. especially a 120mm one.

yeah, unless you modded your fan wires, they are all running at 12v. not a lot of fans will run very well at 5v

Yeah I'm sure they are 5V. I modded them for silence.
