Quick Answer

Fortnite crashes due to cooling issues happen when CPU or GPU temperatures spike past 90C, triggering thermal protection mid-match. Clean dust filters, reapply thermal paste if your cooler is older than 3 years, and add intake fans - this fixes the vast majority of thermal crashes in SA gaming setups.

Why Cooling Crashes Hit Fortnite Specifically

Fortnite's UE5 update pushed CPU and GPU loads sharply higher than the older UE4 build. The combination of high frame rates in competitive mode and Lumen lighting in Performance mode creates sustained loads that expose marginal cooling. Cape Town summer ambients of 30C+ inside an unaired room push case temps another 5-10C. SA gamers on stock AMD or Intel coolers often see Ryzen 5/7 chips touch 95C in long matches, triggering Windows Hardware Error events that crash the game.

Step-by-Step Cooling Fixes

Pop the side panel and check dust load on intake filters and the GPU heatsink first - if it looks fluffy, it's choking your airflow. Blow it out with compressed air. Next, monitor temps with HWiNFO64 during a Fortnite match - CPU package temp should stay below 85C and GPU below 80C under sustained load. If they're higher, check your cooler. Stock coolers struggle with Ryzen 5 5600 and up - swap to a 120mm tower like the DeepCool AK400 or be quiet! Pure Rock 2 for around R600-R900 from Evetech. Reapply quality thermal paste like Arctic MX-6 if your build is older than 2-3 years.

Case Airflow and SA-Specific Tweaks

Two intake fans front, one exhaust rear is the minimum for any modern build. Cable management matters - tucking cables behind the motherboard tray opens up airflow paths. SA summer gaming benefits from desktop fan circulation in the room and cracking a window if security allows. Avoid placing the PC in an enclosed cabinet. Evetech ships coolers and case fans nationwide with same-day Gauteng dispatch.

Frequently Asked Questions

What CPU temperature is too high for Fortnite?

Anything sustained above 90C is risky. Brief spikes to 92-94C during loading are fine, but long stretches above 90 indicate a cooling problem worth fixing.

Does an AIO cooler help with Fortnite cooling crashes?

Significantly, especially for Ryzen 7 and i7 chips. A 240mm AIO drops sustained gaming temps by 10-15C compared to most stock coolers, eliminating thermal throttle crashes.

How often should I reapply thermal paste in SA conditions?

Every 2-3 years for tower coolers, sooner if temps creep up over time. SA dust accelerates pump-out on older paste, so an annual visual check pays off.
