H100i v2 fan direction(s) - seeking advice

I recently posted about CPU temp and ended up with an Amazon Prime Day deal for an H100i v2 liquid cooler for my 6850k. I'm looking for advice on how to best configure fans for my case and/or someone to tell me to just stop obsessing (I burned out a CPU by being stupid, as you can see in the prior post, so I'm being especially cautious with the replacement).

Here's a photo of my current setup - it's an older photo because I forgot to take a new pic before putting the top on with the new cooler. Anyway, I guess my question is: should I switch one of the fans in the H100i to pull fresh air in while having one push air out, or am I just splitting hairs? I've noticed that when I overclock the 6850k to 4ghz (from 3.6ghz) the temperature of the liquid slowly rises to around 33C and the CPU runs a bit warm at idle (39C). When I don't overclock, it runs around 30-32C at idle and the liquid temp is around 30C. I'm doing exhaust to keep the rest of my components cooler, but maybe it can be the best of both worlds if I have one fan as intake and one as exhaust across the radiator?

Solution
Fans coming with liquid coolers are made so they have higher static pressure to better blow thru dense radiator cells. Because of that it's best to place them to blow thru radiator, preferably to outside of the case.
