So im playing some Rust and from time to time i noticed my PC LED fan flashing.When PC is idle fan is not flashing.
pls halp

read the motherboard manual to see what the flashing mean

I dont mean motherboard stuff flashing ,i mean my LED fan flashing and he is conected directly to the psu by the molex

dimming could be caused by a voltage drop under load....

But if just one fan, reverse some fan connections to see if it is isolated to just one LED within one fan..

Thats only case fan that i have lol ,and whole thing shuts down i mean LEDS ,idk its maybe PSU problem?

 

[rgd1101]

Maybe is a feature on the fan that flash when not idle?

 

[mdd1963]

Possibly it is set to glow in sync with different load/frequency levels under assorted varying loads....i'd not worry about it if all other performance is ok...

See if it is bright in a Defender scan, and then semi-dim during idle....

If so, it might be a normal 'feature'....

How can it be in sync with different load when its connected to the psu and its like 4 dollar fan.

Then maybe is your issue with your cheap fan. try a good brand name one and see if it still does that

But it only flashes when pc is under load ,so thats kinda scary
