What to Expect From Your Open-Loop PC



The following are considered normal characteristics of your open-loop PC system. Understanding them will help you ensure optimal performance.
Expectations
System Temperatures
GPU
- Ideal: 30–65 °C during normal usage
- Maximum: Up to 85 °C under heavy load, depending on your GPU model
CPU
- Ideal: 40–70 °C during regular use
- Maximum: Up to 90 °C under heavy load, depending on your CPU model
Note: Temperature limits can vary based on your specific CPU and GPU.
Coolant Evaporation
Drops in coolant levels over time are normal. These may need to be refilled every 3-6 months. (Distilled water is only suitable for top-ups)
Noise from Pump and Fans
Continuous noise from the pump and fans is normal; they maintain optimal system temperatures. After transit, air bubbles may temporarily increase noise.
Tubing Wear and Tear
Minor discolouration or wear on tubing over time is normal. Regularly inspect for blockages or leaks.
Scheduled Servicing
Service your open-loop PC every 18 months for peak performance. This includes coolant replacement and a system check. Note: Servicing is at your cost. Contact us for assistance.
RAM Training
Systems with large amounts of DDR5 RAM may take longer to boot due to RAM training. This is normal and ensures optimal performance.
Fan Behaviour
Fan spikes (increase in speed and noise) are normal as the PC is used. The system's fans may take time to spin up as the coolant heats up gradually. After intensive use, the fans will take time to return to their normal operating speed as the coolant cools down.
