the casing is Meshify C w/ 2 corsair AF140 quiet for intake. 1 AF120 for exhaust.
here is my idle temperature. https://prntscr.com/hrokps, is it good or bad? when I browse the web it randomly spikes 50+ to 60c. and when I run Nox it reaches 70c+
which is much better? cryorig h5 universal or be quiet shadow rock 2?
Not much difference there. I'd stick with your H5. Temps will be high with the i7-7700K unless you get a good liquid AiO or delid and replace stock TIM with liquid metal. As long as you're not seeing 80C+ on a regular basis, I wouldn't bother spending the extra money on cooling.
