I not see in Helios64 assembling guide, how should be set coolers.

Where should be directed airflow? Inside or outside the case?

Helios64 assembly instructions have you mount the fans as to pull fresh air trough the front grill: https://wiki.kobol.io/helios64/kit/#step-7-install-back-panel

Thank you for tip.

But I not see that on link you provide. Maybe be better to add that info it clear text into document you refer to.

Strange that the website doesn't display properly for you. You might have a rogue extension installed.
Here's a screenshot of installation step number 7, which is the step that takes care of fans.

 

I see that picture, but not see there airflow direction.

Possible this mark should be more clear or bright.

Is it so hard to just text something "air should go inside" or draw an arrow?

That certainly could be added. I think the assumption was that as long as people were following the directions it would be fine. Otherwise, since the rule is that air exhausts on the side of the fan with the motor, it's clear from the picture that air would be pushed out the back of the case.

Hi! I'm not sure what you mean by "air should go inside"... If you follow the pictures carefully (and you observe the fans blades orientation) you'll notice that fans are mounted in such a way that they pull air outside through the case back panel. Which is what you should expect typically anyway. Fresh air comes inside through the front grill, flows through disks and the Helios64 SBC board and then is pulled out by the fans. But yes, I agree that ideally and to avoid any possible misinterpretation some arrows/text should be included to indicate the proper airflow direction.
