If so i highly suggest not to buy it unless you already have it. Your case doesnt support 240mm radiator or tall coolers (up to 148mm)

I would buy a new case to fit cheaper and better coolers.

I have the same CPU and MOBO. EVGA ACX cooler (red LED)...and F6 bios. CPU is spiky (hitting 80-100% usage with anything, for example opening Chrome)...and then going down... and again. I can hear my cooler revs up and down all the time. What's Your setup?

Sorry for offtopic...

the 7700k as mentioned is spiky and temps can run high even with a good cooler. i would go with a big air cooler or a 280mm+ aio, depending on what you can fit. and even with that dont expect a huge oc.
