4500 rpm h110igtx .... Extreme Loud

Hi,

I have a question :

When playing games my CPU watercooling Fans Start going mad as soon as my CPU Hits 50degree Celsius.... Its extreme noisy and i dont know why. All the sudden my fans from my h110igtx rotate at 4500rpm.. I cant stop that ... After 10 Minutes of Gaming this will allways happen.

My System :

2x 980 ti Windforce Extreme Edition 6700k Skylake Gigabyte z170 Gaming 7 16 gb ddr4 geil Lucy RAM

Watercooling CPU : corsair h110igtx

Im currently playing Overwatch (1440p res, 120-250 fps , gpu Max temp is 71 and cpu is about 40-55 )

Please help me i have for the newest Version of corsair Link and used the Different Profiles but they all have the Same Problem ....

"Speed fan " cant detect any Fans . And i cant find a way to adjust Fanspeed in corsair Link . And When using Gigabyte App Center i can Control all Fans but not from my AIO watercooling ...

Should i buy Other Fans? Can Limit rpm somehow?

And
