The high ambient temps are going to be an issue...you have to have a jacketed conical, and you'd do well to insulate the legs and any parts of pieces that stick out.
All those things--handles, ports, legs, chiller ports--act as reverse radiators, drawing ambient heat into the fermenter. You're going to need a glycol chiller to be able to combat that, in addition to whatever insulation you might be able to add.
One other possibility is this: you can build a small "closet" inside which you place the fermenter. The coolness lost to normal processes will cool that "closet" to temps lower than ambient, and that will help. I found that 2' sections of hardboard (what pegboard is made from with the holes) will do that. Pieces of 2x2 on the corners to screw to, maybe some 1" foam board insulation inside, and you have a more moderate environment in which to chill.
Here's something I did; you can see the black chiller lines coming into the box from the upper right where they exit the camoflage refrigerator:
I have the Spike CF10 with the temp kit, running off my home-made refrigerator/freezer chiller. It's not enough of a chiller to do the job--I have a Penguin on the way--so to try to make up for that I built the thing you see in the pic above.
The sides are 4' high, 2' wide, and then a 1-foot "cap" on top.
FWIW: My ambient on hot days is in the mid-to-upper 80s. Just too hot for my homemade chiller. So the idea behind the "closet" was for me to put a window airconditioner in, and direct the cold air flow into the "closet" through a hole in the "cap." This dropped ambient to the 50s, which helped. My design above used actual 1/4" pegboard for the sides, so the air would be able to flow through and out those holes. If just for insulation, I'd have not used pegboard, I'd have used regular hardboard. Of course, plywood, osb, any sheet good would work.
In the end, my homemade chiller wasn't able to get temps down to where I wanted--my goal is 32--and it just wasn't enough. Several reasons related to the design of my chiller, which is more than able to manage ale fermentation temps in a warm garage. But I want to cold-crash low, and it just couldn't do it.
Hence the Penguin. If you're getting the sense I'm suggesting you're going to need one, well, I am. You are. But given the ambient temps where you live, I think you also may need something to isolate that fermenter from ambient as much as you can, and you're still going to need to insulate the "pieces" sucking heat into the fermenter as much as you can.
This is going to apply no matter which fermenter you buy. Good luck! Loving my conical. You will love yours.
