Hey you guys I've been wanting to buy a new case for some time now and I've narrowed it down between the cooler master 692 advanced and the Li Lain lancool pc-k62 both cost about the same and are packed full of features. I want to know which one is better for cooling mainly I don't really care about the looks of either one because they both look nearly the same. It's just the CM 692 has a bunch of extra fans slots over the pc-k62. But if I get the CM I'm going to loose the totally tool less design of the pc-k62 so is it worth it. And also I've read that the cm does have as good of air flow even with all of the fan slots filled so what should I do.
Both certainly have excellent cooling with stock fan setup.
You can improve on both by adding optional fans. Not that you'd need to do that.
And you can always add fans later, after you've finished all your multi-GPU CF/SLI and overclocking setups.
Measure your temps before and after - that will let you know if you actually need more case cooling fans.
