What is a Cooling Fan used for in practice?

Cooling Fans are a rare crafting material that most players start caring about when base progression slows down. Early on, you might sell a few without thinking. Later, you realize they are required in Core System and Framework projects, and suddenly you need several at once.

In practice, Cooling Fans are not something you craft directly. You either loot them or recycle them for wires and plastic parts. Because they stack only to three and weigh a fair amount, inventory management becomes part of the problem.

Most experienced players stop selling Cooling Fans once they unlock projects that require five or more. Selling them early feels fine, but later it often means extra farming runs.

Where do Cooling Fans actually come from?

Cooling Fans are found in Technological loot containers. In real gameplay, this usually means Server Racks inside industrial or data-related buildings.

You are not looking for random crates or lockers. Cooling Fans come from a specific loot pool. If a building does not contain server racks or similar tech furniture, your chances are close to zero.

In short:

• Server Racks are the primary source

• Technological areas matter more than map region

• Outdoor loot almost never drops them

Once you learn to recognize server rack rooms, farming becomes more predictable.

Are some maps or zones better for Cooling Fan farming?

Players often ask if there is a “best map” for Cooling Fans. In reality, it is more about building type than map name.

Good farming zones usually have:

• Multiple indoor floors

• Repeatable server rooms

• Fewer wide-open sightlines

Office complexes, underground facilities, and data centers tend to outperform open industrial yards. The key is density. A single building with four server racks is better than three buildings with one rack each.

Over time, most players settle on one or two routes they can clear quickly rather than roaming the entire map.

How often do Cooling Fans drop from Server Racks?

This is where expectations matter. Cooling Fans are rare. You should not expect one every run.

Based on common player experience:

• You might see one Cooling Fan every few full clears

• Some runs will give none

• Occasionally you will get two in a single run

This uneven drop rate is normal. Planning your farming around guaranteed drops will lead to frustration. Instead, stack runs and accept variance.

How do players run Cooling Fan farms efficiently?

Efficient farming is less about fighting and more about movement and timing.

Most experienced players do the following:

• Enter with light gear

• Avoid unnecessary combat

• Prioritize server rooms only

• Extract early once inventory is full

You are not trying to clear the map. You are trying to hit specific rooms and leave alive.

Many players also farm during quieter matchmaking periods. Fewer players means less competition over high-value rooms.

Should you fight AI or players while farming?

Generally, no. Cooling Fan farming is not combat-focused.

AI enemies slow you down and increase risk. Players increase that risk even more. If you are farming Cooling Fans, your goal is survival, not kill count.

That said, some fights are unavoidable. When that happens, experienced players disengage quickly instead of committing. Losing a run with a Cooling Fan in your bag hurts more than skipping a fight.

Is it better to recycle or keep Cooling Fans?

This depends on where you are in progression.

If you still need Cooling Fans for projects, do not recycle them. Projects often require the item itself, not the materials it breaks down into.

Once project requirements are done:

• Recycling gives plastic parts and wires

• Salvaging gives fewer materials but is safer if needed

Many players keep a small buffer, then recycle extras once base upgrades are finished.

Are Cooling Fans worth selling for coins?

Early on, selling a Cooling Fan for coins can feel useful. Later, most players regret it.

The coin value does not scale with progression, but the time cost to re-farm does. Coins are easier to get from other loot. Cooling Fans are not.

Veteran players usually only sell them when they are certain no upcoming project requires them.

How does Cooling Fan farming affect blueprint decisions?

Some blueprints indirectly increase the need for Cooling Fans by accelerating base progression. When players decide to buy Wolfpack blueprint, for example, they often push into systems that require more rare components overall.

This does not mean the blueprint itself consumes Cooling Fans, but it speeds up the stage where Cooling Fans become a bottleneck. Planning your farms ahead of time prevents getting stuck later.

What mistakes do new players make when farming Cooling Fans?

Several mistakes come up repeatedly.

One is farming the wrong loot types. Players search generic containers and wonder why nothing drops.

Another is staying too long. Greed kills more Cooling Fan runs than enemies do.

A third is selling early drops without checking future project requirements.

Learning from these mistakes usually takes a few painful losses.

How many Cooling Fans should you aim to stockpile?

There is no perfect number, but common practice is:

• Keep at least 5 for active projects

• Hold 2–3 extra as backup

• Recycle only beyond that

This gives you flexibility without clogging inventory space.

Is Cooling Fan farming meant to be slow?

Yes. Cooling Fans are designed as a progression gate. They are not meant to be rushed in one session.

Most experienced players spread farming across normal play instead of grinding nonstop. They hit known server rooms during regular runs and let the stockpile grow naturally.

Trying to force it in one evening often leads to unnecessary deaths and frustration.

Final thoughts from long-term play

Cooling Fan farming becomes manageable once you stop treating it as a special activity. It works best when folded into normal runs with a clear plan and a quick exit.

Focus on server racks, avoid fights, and know when to leave. Over time, Cooling Fans stop feeling rare and start feeling like a steady, predictable resource.
