Laptop Fan Replacement Cost Dhaka — Overheating Fix Guide 2026
6 July 2026 · 3 min read · BAYAS Editorial
Laptop fan replacement in Dhaka costs BDT 1,500–3,500 at BAYAS — labour plus a genuine replacement fan. A noisy, grinding, or completely silent fan is the most common cause of laptop overheating, thermal throttling, and unexpected shutdown. BAYAS replaces laptop cooling fans at your home across all 36 Dhaka zones.
Dhaka's climate makes this repair especially urgent — ambient temperatures of 35–42°C in summer mean a laptop fan working at even 70% efficiency can push CPU temperatures above the 95°C throttle threshold, causing the machine to run at 50% speed or shut down entirely.
Signs Your Laptop Fan Needs Replacement
| Symptom | Likely Cause |
|---|---|
| Loud grinding or rattling noise | Fan bearing failure — replace immediately |
| Fan runs at full speed always | Thermal paste dried, fan sensor fault, or thermal throttling |
| Complete silence during heavy load | Fan dead — overheating imminent |
| Laptop shuts down after 15–30 min use | Fan dead or clogged, causing 100°C+ temperatures |
| CPU clock speed drops under load | Thermal throttling due to overheating |

How do I know if my laptop fan is dead or just noisy?
A dead fan is completely silent during heavy CPU loads (video rendering, gaming). Download HWInfo64 — if CPU temperature exceeds 90°C under light load, the fan is likely dead. A noisy fan (grinding, clicking) still moves air but the bearing is failing — replace it before it seizes completely.
Can BAYAS replace a laptop fan at my home in Dhaka?
Yes. BAYAS carries common replacement fans for HP, Dell, Lenovo, Asus, and Acer laptops, plus thermal paste. Most fan replacements take 45–75 minutes at your home. MacBook fans require ordering 1–2 days in advance. WhatsApp 01712-644590 to check stock for your specific model.
Should I clean or replace my laptop fan?
If the fan is noisy (grinding/clicking), replace it — cleaning only delays failure. If the fan is silent but the machine overheats, start with cleaning (BDT 1,500–2,000). BAYAS advises honestly after in-person diagnosis.
