So I am going to be building my first build pretty soon and want it to look pretty cool, It is currently white and black and i will be using rgb lights to reflect off of the white component areas. I have been looking into cpu coolers and decided that although an aio would look better I would rather not risk a leak. So it has been put down to air cooling and although i know that many people like the big heatsink coolers i do not and have to say my favorite of all the coolers are the flat on slimline ones like this which show the fan, my only concern is their ability to cool, i know their main use is for itx/matx but i am just using atx and like their looks. I will be lightly overclocking an i5 7600k, thanks
