hey hi guys, my self phani....im from India, i am using Sapphire toxic R9 280X graphics card, and here in my place the temperature is too high, the stock coolers which are given by sapphire are not at all sufficient, i am looking forward to buy NZXT kraken G10 for my GPU, it's been three months that i've purchased sapphire toxic r9 280x, here the issue is if i remove stock cooler from GPU i am going to lose warranty, is there any way to avoid this problem? without loosing warranty how can i fix NZXT?
