How to Play Data Center Fan

The core loop

Every run follows the same rhythm: buy hardware, sign contracts, earn cash and reputation, then reinvest to unlock a bigger facility. You place servers and infrastructure on an isometric grid, and each machine you switch on draws power and produces heat that you must offset with cooling.

Your goal is steady, compounding growth. Spend just enough to keep contracts served and reputation climbing, and bank the rest toward the next tier.

Your first five minutes

1. Buy a server — Start with the cheapest desktop-class server. It provides the compute you need for your first contract.
2. Add power — A basic power strip supplies the wattage your server draws. Without enough power, servers cannot run.
3. Add cooling — A window AC or small cooler removes the heat your server generates. Overheating hardware degrades and fails faster.
4. Accept a contract — Open the clients panel and accept a simple, low-SLA contract. It pays you per second as long as you meet its uptime target.
5. Reinvest — Use the income to buy a second server or better infrastructure, then repeat.

Balancing power, cooling and compute

Three resources keep your facility alive: power (kW), cooling, and compute (vCPU, RAM and GPU). Power must exceed total draw; cooling must exceed total heat; and compute must meet the demands of your active contracts.

When any resource runs short, performance and uptime suffer, which hurts the reputation you need to unlock higher tiers. Upgrade infrastructure a little ahead of demand so a new contract never tips you into the red.

Client contracts and SLAs

• Contracts range from personal blogs to global megacorporations. Bigger clients pay more but demand higher uptime and more capacity.
• Each contract carries a service-level agreement (SLA). Meet the uptime guarantee to earn cash and reputation; miss it and you pay penalties.
• Do not over-commit. Signing a contract you cannot serve reliably will cost you more in penalties and lost reputation than the income is worth.

Handling random events

Events keep every run tense: brownouts, DDoS attacks, ransomware, fiber cuts, hardware failures, compliance audits and viral traffic spikes. Each event offers choices, and your decisions shape your reputation and your bank balance.

Hiring the right staff — a security analyst, a facilities manager — reduces the severity of many events, and the Insurance prestige upgrade softens the worst of them.

Staff, research and prestige

As you grow, hire technicians, network engineers, security analysts, sales reps, facilities managers and a CTO. Staff level up over time and each improves a different part of the operation.

Unlock research to boost income, efficiency and reliability. When you reach the top tiers, trigger an IPO to prestige: you reset the run but earn Innovation Points that buy permanent upgrades, making every future run stronger.

Beginner tips

• Keep a small cash buffer so a surprise event never bankrupts you.
• Upgrade cooling before you add a batch of new servers, not after.
• Chase reputation early — it gates the next tier as much as cash does.
• Repair or replace degraded hardware before it fails during a contract.
• Your facility keeps earning while you are away, so check back for offline income.

Frequently asked questions

How do I unlock the next tier?

Each tier unlocks when you reach both a cash threshold and a reputation threshold. Keep contracts served to grow reputation while banking cash toward the requirement.

Why are my servers failing?

Servers overheat when cooling cannot keep up with the heat they produce, and hardware degrades with use. Add cooling capacity and repair or replace worn hardware to keep uptime high.

What is an IPO in Data Center Fan?

An IPO is the prestige mechanic. At the top tiers you can reset your run in exchange for Innovation Points, which buy permanent upgrades such as more starting cash, higher income and cheaper power.
