Acer Predator Helios 300 Fan Set — High-Performance Cooling Restored
The Acer Predator Helios 300 Fan Set is the correct dual-fan replacement unit for one of the most popular gaming laptops in Pakistan. The Predator Helios 300 carries high-TDP Intel Core i7/i9 CPUs paired with NVIDIA RTX graphics — a combination that demands reliable, high-airflow cooling at all times. When one or both fans begin to rattle, stop spinning, or fail to ramp up under load, thermal throttling kills frame rates almost immediately. This fan set resolves that exactly, restoring the original dual-fan airflow architecture without any chassis modification.
Each fan in the set is built with an aluminum frame and precision ball bearings, matching the original OEM RPM curve and 4-pin connector pinout. Tested and quality-checked at our workshop at Hafeez Center, Gulberg III, Lahore — we spin each unit and verify the connector continuity before it goes into a box.
Signs Your Helios 300 Fan Set Needs Replacement
- Loud grinding or rattling at medium or high RPM — bearing wear, not dust
- CPU or GPU temperatures above 95°C at moderate load — airflow is compromised
- Thermal throttling mid-game — FPS drops sharply when the chip hits its thermal limit
- Fan not spinning even when the laptop is hot — motor or connector failure
- Fan error at POST — the BIOS detects zero RPM and halts or warns
Compatibility Details
This fan set fits the Acer Predator Helios 300 PH315-52, PH315-53, PH317-53, PH317-54 and closely related Helios 300 variants produced between 2019 and 2022. The model number and chassis revision are printed on the sticker underneath your laptop. If you are unsure which revision you have, WhatsApp Sayam at 0314 4000131 with a photo of that sticker — we will confirm the part number before you order. Customers from Lahore, Karachi, Islamabad, Rawalpindi, Multan, and Faisalabad do this regularly.
What Is in the Box & Installation Notes
You receive 1 x Acer Predator Helios 300 Fan Set — both fans (CPU heatsink fan and GPU heatsink fan) as a matched pair. Installation requires a Phillips PH00 screwdriver and takes 25-35 minutes. During reassembly, apply a thin layer of quality thermal compound to the CPU and GPU die contact points on the heatsink — the old compound will have dried out and should be fully cleaned before applying fresh paste. Cure time before full-load use is about 2 hours for the compound to settle.
