Hello.
The GAMMAX 400 can be noisy sometimes. I've long since replaced mine with a PWM Cougar fan. As for performance, with the stock fan, the Hyper 212X should be better. The Gammax 400 wasn't better than the 212EVO after all.
Check that here:

When looking for a casing, check the rated "Maximum CPU Cooler Height". The GAMMAX 400 is 154.4MM high, and the 212X is 158MM high.
CRYORIG H7 - Entry Level Cooler Price: Rp 450,000
Cooler Master HYPER 212X TURBO Price: Rp 540,000
Deepcool Gammaxx 400 - Fan 12CM LED Price: Rp 308,000
if Hyper 212X turbo is FAR better than Gammaxx 400 in every aspect. then, I will justify the extra cost. if It only wins slightly then I will stick with Gammaxx 400
