LED Fans

[foster grant]

OK I have These Fans and This Cooler....this morning when I booted my system ...I noticed that the two fans were nice and bright for about 3-4 seconds , But after that they seemed to dim down to maybe half the brightness , This is normal ?

the two fans are connected to the "CPU_FAN" Via the "Y" connector that came with the Cooler itself

The brightness of the LED is linked to the current being drawn by the fan, I am guessing your set up is controlling the fan speed depending on CPU temperature, you wil see the LEDs get brighter when the CPU temp causes the fans to need to spin faster.

See if you can force them to run at full speed (turn fan control off in BIOS if possible) and check the brightness. It could be that they dim with lower voltage

Edit: As above
