Fan question

On the new Rostock Delta mini that I am building, a fan comes with the kit that must be mounted below the platform, blowing at the object for cooling.

On my current printer (Orca v04x) a fan is cooling the input side of the hot end. No fan on the object and I have never missed it.

So.. what is the reason the Rostock has a fan below ? Can I leave it away ?

It is just a layer fan for when you print pla. You don't need it, but many add it to reduce stringing and come out with a better part. I currently do not have a layer fan equipped on my rostock, and my prints have been good, but I am planning to print a layer fan shroud later today.

Thanks,

I will start without, as I always print PA on my Orca without and I don't know what i miss "-)

It really depends what you intend to print. I have always found small or pointy parts come out much better with a fan blowing air over them. I've always figured that they are easy to fit and can't hurt. I actually have the opposite problem as I use Cura and keep forgetting to turn the fan off for ABS prints. I spent ages trying to figure out what was causing parts to warp off the bed that had always printed ok before. If nothing else it proved the fan was effective!
