Arc Raiders drops you into a brutal world where every raid counts, and nothing stings quite like staring down an expedition deadline with zero Cooling Coils in your stash. These rare industrial beauties are key for phase two crafts – you need four alongside stacks of Durable Cloth, Wires, and Electrical Components – and they're notoriously stingy on drops. I've burned through dozens of runs myself, dying to ARC swarms and rival raiders, just to pry open that one red locker with the goods. But after mapping it out, I've nailed consistent farms. Here's the no-BS guide to scoring Cooling Coils fast, from low-risk scraps to high-reward death traps.

That coiled hunk of metal? Sells for 1,000 coins, recycles into 6 Chemicals and 2 Steel Springs. Salvage for pure springs on Topside. Always stash in your Safe Pocket – death means goodbye loot.
Unlike common junk, Cooling Coils hide in industrial zones (spot the factory icon on maps). No crafting or trading them directly – pure RNG grind. Drop rates suck; expect 1-2 per solid run if you're thorough. Pro tip: Pair with Adrenaline Shots for speedruns, and unlock Breach & Search early for locked goodies.
Dam Battlegrounds reigns supreme – compact, loot-dense, but player-infested. Spaceport's massive but spread out. Blue Gate's safer for solos.
| Map | Best POIs | Risk Level | Avg. Coils/Run | Notes |
|---|---|---|---|---|
| Dam Battlegrounds | Hydroponic Dome Complex, Water Treatment Control, Power Generation Complex | High | 2-3 | Red lockers galore; grab Dam Surveillance Key for locked rooms. |
| Spaceport | Rocket Assembly, Vehicle Maintenance, Container Storage | Medium | 1-2 | Multi-floor lockers; northern Rocket Assembly is gold. |
| The Blue Gate | Warehouse Complex | Low | 1 | Top-floor locker row; inconsistent but chill. |
| Stella Montis | Lobby Metro, Loading Bay | Very High | 1-2 | Endgame only; aggressive PMCs. |

See that highlighted Hydroponic Dome on the Dam map? Southwest corner, packed with domes hiding the prize.
Drop in Dam and beeline southwest – Hydroponic Dome Complex is your mecca. Larger domes pack red lockers (your coil jackpot), breachable metal crates, and toolboxes. Clear ARC patrols first; it's a hotspot for squads. I've pulled 3 in one run here, but watch flanks – raiders camp entries.
Next: Water Treatment Control. Nab the Dam Surveillance Key (drops nearby) for the locked room – left-side locker row often coughs up coils. Check generators, car hoods outside.
Power Generation Complex nearby for overflow. Scrap Yard south is low-risk filler, but skimpy yields. Loading Bay (between Research/Admin and Primary Facility) is underrated – dense crates, low traffic.
Route: Spawn > Hydro > Water Treatment > Extract. 10-15 mins, 2+ coils average.
Big map, big risks from distance. North Rocket Assembly: Hit floors 1-2 for red lockers stuffed with epics and coils. From there, short hop to Vehicle Maintenance and Container Storage – more lockers, generators.
Shipping Warehouse north edge is a trek, low odds. Spawn close or skip.

Rocket Assembly's yellow zone on this Spaceport map? Prime real estate.
Warehouse Complex center: Top floor lockers. Adorned Wreckage west if you spawn near. Great for quick ins/outs.
Stella Montis for vets – high loot, high sweat.
Prioritize these – wiki-confirmed spawns.
| Container | Spawn Rate | Best Map/POI |
|---|---|---|
| Red Locker | High | Hydro Dome, Rocket Assembly |
| Industrial Drawer | Medium | All industrial |
| Car Hood/Tool Cabinet | Medium | Vehicle Maintenance, outdoors |
| Mobile Generator | Low-Medium | Power Gen, Water Treatment |
| Metal Crate/Bus | Low | Scrap Yard, Loading Bay |
