Fans flickering in computer

[Oldnavy180]

Hello, I have a 530w psu and a motherboard with 2 fan headers. One of my fan headers has 4 fans hooked up to it and my other one has one. My lights flicker when I turn up all of my fans. I don't think my psu is an issue because on average my computer uses low 300w of power. My fans are 4 corsair af120 quiet edition blue led fans and 1 corsair af120 red led fan (red came with case)

Why is this? Is there anyway to solve it?

Running 4 fans with LED could eventually lead to a failed fan header. You may be able to connect 2 and then use a fan controller for the other 2.

Is this a good fan controller? http://www.amazon.com/gp/product/B00KJGYLNM/ref=s9_simh_gw_p147_d0_i1?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=desktop-2&pf_rd_r=00RAQM2V325XQQRAX3EK&pf_rd_t=36701&pf_rd_p=2091268722&pf_rd_i=desktop

Yes but there's also http://www.amazon.com/NZXT-Technologies-Sentry-Controller-SEN-MIX2-M1/dp/B00DN3IT7M/ref=sr_1_1?s=electronics&ie=UTF8&qid=1434247117&sr=1-1&keywords=NZXT+SEN-MIX2+Sentry&pebp=1434247435472&perid=C519C860612545559942 According to a few reviews, those controllers may not allow running the fans at less than 40% of their maximum speed.
