I may end up doing the bucket alternative I see here with the storage bin and the double barrel vans/vents.
Are people trying to give me a stroke! The gap is needed!!! It is an essential requirement.
If the gap is insufficient, then you're limiting the cooling potential and may be drying out portions of the pad and thereby mixing in some hot dusty air into the air you've cleaned & cooled.
Post some photos and we'll [strike]slap[/strike] critique your implementation.
If you need more airflow/volume for the size of your structure, go to one of the Quiet Breeze designs; amazing fan.

Perhaps mine worked fine because I used a fan with a very high static-pressure rating (Noctua SSO2 NF-A14 iPPC-3000) ...
If it has the usual number of holes of the original size, or smaller holes not under 1" diameter providing the same total hole area, then you are fine.
I love those fans for my computers. But that one only has 10,52 mm of static pressure. You're a little low on static pressure, so you'll be a little low on sucking airflow through the pad...
How about posting photos so we can see if there are any deficiencies in pad installation, gap, etc.?
Since you're an old hand and should know better, we won't slap you hard unless you pay extra.
The original recommended fan is the first one here (SHE):
- AFB1212SHE-CF00 190 cfm, 17.74 mm H2O, 1.6 A, 55.5 dBA, 4100 rpm
- AFB1212GHE-CF00 240 cfm, 27.48 mm H2O (22), 3.24 A (2.45), 66 dBA, 5200 rpm
So the GHE looks like figjam's original SHE, but on steroids: more pressure, more cfm, more noise and - more amps.
We're waiting to hear back on how the GHE works. As in, is it too much airflow for the pump to keep the pad wet. Noise, etc..

I think I have a pretty solid case against the creation / use of a swamp cooler at this point--and instead using a manufactured air conditioner.
Figjam has already explained about gap and "newer".
Actually, you make the case for what we keep saying over and over and over again. Don't vary from Figjam's designs if you need/want cooling, unless you really know what you're doing. (Or want something to play with.) If you need/want to vary, then ask. Photos help a lot.
