Problem with Fun

Hello. I have a 

COOLERMASTER R4-JFDP-20PB-R1 JETFLO

with led light. Fun's led brightness depends on how fast the blades rotate. I mean if the fun is rotated at low rpm the led is almost turned off, on the other hand if it is rotated fast, the led is very bright. Is this usual?

That does not seem normal to me if it's using PWM, but if it's DC controlled than the whole fan gets less voltage so than it's logical.


PS. I am not english myself so it's no problem that you misspelled "fan" as " fun"  but its just a really funny mistake

I make Rainmeter things and other art :D

I assume you connected the fun via pwm

Yes..Likewise, because the cable is short to reach the motherboard, coolermaster provide 2 extensions with the fan, One 1200 rpm and one 1600 rpm. I tried both and on different fan connectors but remain the same problem.

i was legit thinking you had a problem with haveing too much fun or something... xD

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

Builds:

The Toaster Project! Northern Bee!

 

The original LAN PC build log! (Old, dead and replaced by The Toaster Project & 5.0)

"Here is some advice that might have gotten lost somewhere along the way in your life. 

 

#1. Treat others as you would like to be treated.

#2. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt.

#3. There is nothing "wrong" with being wrong. Learning from a mistake can be more valuable than not making one in the first place.

 

Follow these simple rules in life, and I promise you, things magically get easier. " - MageTank 31-10-2016

Is mobo set to control fan with PWM instead of DC?

The silent mode adapters don't use pwm. If you want to keep the led bright, use pwm without the adapters.
