The snake method holds a steady 225–275°F on a charcoal grill by burning briquettes in a slow-moving line — it costs nothing but demands vent tweaks and occasional babysitting. An automatic fan controller like the BBQube TempMaster Pro does the same job hands-free by feeding air on demand, which matters most for overnight cooks and long briskets. Both get you great low-and-slow barbecue; the right choice comes down to how involved you want to be.
What is the snake method?
The snake method (also called the fuse or C-shape method) is a way of arranging charcoal so it burns slowly and predictably over many hours. You line up unlit briquettes in a curved row — usually two-wide and two-high — around the perimeter of a kettle or kamado, then light just a few coals at one end. The fire creeps along the "snake" like a lit fuse, releasing a small, consistent amount of heat instead of igniting all at once.
A typical Weber Kettle snake using standard briquettes will burn for 6–10 hours and hold roughly 225–250°F once dialed in. Add a few wood chunks along the row for smoke, drop a water pan inside the curve to stabilize temperature and humidity, and you have a genuinely capable low-and-slow setup with nothing but charcoal and vents.
How to build a snake that holds 225°F
- Lay two briquettes wide, two high in a C-shape around the edge of the charcoal grate, leaving a gap so the fire can't jump the ends.
- Place 3–4 wood chunks spaced along the first third of the snake for smoke early in the cook.
- Set a water pan in the center to buffer temperature swings.
- Light 8–12 coals in a chimney and pour them at one end only.
- Crack the bottom vent about a quarter open and the top vent halfway, then adjust in small moves to settle at your target.
The key skill is patience: make one small vent change at a time and wait 15–20 minutes to see its effect. Chasing the temperature with big adjustments is the number-one cause of wild swings.
How does an automatic fan controller work?
An automatic temperature controller replaces guesswork with a feedback loop. You seal off most of the grill's bottom vent and attach a variable-speed fan through a grill-specific adapter. A pit probe measures the actual air temperature inside the dome, and the controller runs the fan just enough to hold your exact target. Want more heat? It blows harder. At temperature? It idles the fan and lets the fire settle.
Because the controller reacts continuously — not once every 20 minutes like a human — it holds a much tighter temperature band and recovers fast when you open the lid. The BBQube TempMaster Pro pairs a variable-speed fan with a multi-probe thermometer, phone-app monitoring, and even a sous-vide mode, and it fits Weber Kettle, Weber Smokey Mountain, Big Green Egg, Kamado Joe, and Akorn Kamado with the right adapter. Set your target, and you can walk away.
Note the important limit: a fan controller is for charcoal and close-lid grills. It is not a pellet-grill controller, and it works by managing airflow to a live fire — so you still light the coals and add wood yourself.
Snake method vs. automatic fan controller: which holds temperature better?
Both can produce excellent barbecue. They differ in effort, precision, and how forgiving they are.
Temperature stability
A well-tuned snake holds within about ±15–25°F over a long cook, but it drifts as coals burn down, wind picks up, or ambient temperature drops overnight. A fan controller typically holds within about ±5–10°F because it corrects the fire in real time. If you open the lid to spritz, the fan ramps up and brings you back to target in minutes rather than the half-hour a snake might need.
Hands-on time
The snake is the more involved craft. Expect to check vents periodically, especially in the first hour while it settles and again as the fire nears the far end. That's fine for a lazy Saturday when you're home anyway — but a 12-hour overnight brisket means setting alarms or accepting some drift. A controller removes those wake-ups entirely; the app pings your phone if anything strays.
Cost and simplicity
The snake wins on cost — it's free and uses gear you already own. A controller is an upfront purchase, but it pays back in fuel efficiency (no over-firing to compensate for swings), consistency, and reclaimed time. Many cooks learn the snake first, then add a controller once they're smoking often or doing overnights.
Fuel efficiency
Both are efficient because both restrict airflow. A controller edges ahead on long cooks because it never over-feeds the fire — it burns exactly the charcoal needed to hold your number, so a full basket of lump in a kamado can run remarkably long.
When should you use each method?
- Use the snake method when you're learning charcoal control, doing shorter daytime cooks (ribs, chicken, a small pork butt), or you simply enjoy tending the fire and want to spend nothing.
- Use an automatic fan controller for overnight briskets and pork shoulders, competition-style consistency, cooks where you'd rather host guests than babysit vents, or windy days that wreck manual temperature control.
- Use both skills long-term. Understanding vents and fire management makes you a better cook even after you automate — you'll know why the controller is doing what it does.
Learn the craft first, then automate
We genuinely recommend building a few snakes before you buy any gadget. Feeling how the top and bottom vents balance airflow, watching a water pan smooth out spikes, and learning your grill's personality is the foundation of good barbecue. Once you've got that, a controller isn't a crutch — it's a labor-saver that applies the same principles more precisely than any human can.

Quick reference: doneness targets for low and slow
- Pork butt / shoulder: pull at about 203°F internal for shreddable meat.
- Brisket: probe-tender around 200–205°F; expect a stall in the 150s–170s°F.
- Pit temperature: 225–250°F is classic low and slow; 275°F trims hours off with great results.
- Ribs: done by feel and bend, typically after 4–6 hours at 225–250°F.
Whether you run a snake or a fan, the goal is the same: a steady pit and a relaxed cook. Master the manual method for the knowledge, then decide whether set-and-forget is worth your weekend.
FAQ
Does an automatic fan controller replace the snake method entirely?
For many cooks, yes — a controller holds temperature more precisely and hands-free, so you don't need to arrange coals in a snake. That said, you still light the fire and add wood chunks, and knowing manual vent control makes you a better troubleshooter.
Can I use a fan controller with the snake method at the same time?
You can, but it's usually unnecessary. A controller works best with coals arranged in a basket or ring so the fan can influence the whole fire. A tight snake fights the fan's airflow control, so most people pick one approach.
How long can a snake burn before I need to refuel?
A full two-by-two snake around a Weber Kettle typically burns 6–10 hours on standard briquettes. For cooks longer than that, plan to add fuel or step up to a controller with a large charcoal basket.
Will a fan controller work on my Big Green Egg or Kamado Joe?
Yes. The BBQube TempMaster Pro fits Big Green Egg, Kamado Joe, Akorn Kamado, Weber Kettle, and Weber Smokey Mountain using grill-specific adapters. It's for charcoal and close-lid grills only, not pellet grills.
Is the snake method or a controller more fuel-efficient?
Both are efficient because both limit airflow. A controller usually edges ahead on long cooks since it feeds the fire only as much air as needed to hold your target, avoiding the over-firing that manual swings can cause.
