Best led fans for kraken x61

I recently built a new pc and i got the kraken x61 as the cooler its a very good cooler. Got an amd 8350 and it never got over 30C under full load. What im looking for though is fans for it in particular led fans to help light up the inside of my case but without sacrificing performance. I have been looking and think that the cougar linup of led fans are good compared to the sp from corsair. The sps have a bunch of bad reviews of the leds burning out so any suggestions are welcome. thank you for your time. btw im new to the forums so go easy lol

I've had  2 AF's and 2 SP's running for a couple months now. no hiccups. also all four are blue

Afs on the bottom side? Still kinda meh on exactly where to use static pressure vs airflow. But I assume af on bottom and sp on top correct? Also it looks good

actually sp's for intake (its tight) and af's for exhaust
