Case fans and heatsink running when computer enters sleep, how to fix?

I have a CoolerMaster HAF912 tower. There are 2 fans for intake in the front, two fans on the top for the air to flow OUT, and a single fan on the back of the case (also OUT). I have noticed that when the computer enters sleep mode, after 15 mins of inactivity, all of the fans are still going and the heatsink is still chugging along at 100%.

This is normal when the computer is being used, but I'd like the fans to shut down so they're not running 24/7 when it's in sleep mode. Also, I don't want to have to manually shut down the computer every time I step away. Any suggestions?

Not sure if this has something to do with it, but I just added a fan on the top (OUT fan) since I got a coolermaster 120mm fan cheap on Newegg. Thank you.

Well, think I answered my own question. Unplugged and replugged the fan and viola, now all the LED fans will turn off once hibernation starts (5 mins after sleep mode initiated).
