How to Keep Your PC Cool Through a Dhaka Summer

Dhaka summers are brutal on electronics. April through September ambient temperatures regularly cross 35°C indoors, and with the load-shed surcharge of stop-start cooling, PCs and laptops suffer accelerated thermal wear. We see board failures, swollen batteries, dried thermal paste and burned fans every week from June onward.

A few habits and one annual service stop those failures before they happen.

Why heat matters more than people think

Every 10°C over 70°C halves the expected lifespan of capacitors on a motherboard. CPUs and GPUs throttle long before they hit shutdown — meaning your PC may already be running 30 to 50% slower than its rated performance and you will never know unless you check.

The 4 things to do every summer

1. Repaste the CPU and GPU annually

Thermal paste dries out in Dhaka heat in 12 to 18 months. Repasting drops CPU temperatures by 8 to 15°C on most desktops and laptops. BAYAS offers an annual repaste service starting at BDT 1,500 at home.

2. Clean dust filters and fans

Dust acts as insulation. A laptop with caked vents can be 20°C hotter than a clean one. Use compressed air on the intake side, never blow dust deeper into the case. For desktops, vacuum the front filters monthly during peak summer.

3. Verify fan curves

Many laptops ship with conservative fan profiles. Apps like HWiNFO64 or the manufacturer's own utility let you increase fan speed at lower temperatures. The noise tradeoff is worth it for the lifespan you gain.

4. Mind your case airflow

Cable mess and full-height GPUs choke airflow. We see expensive gaming PCs throttling because the front intake is blocked by a hard drive cage or a tangle of unused cables. A 20-minute cable cleanup can drop temperatures by 5°C.

Signs your PC is already overheating

• The fans spin loud constantly, even on the desktop.
• Games or video editing apps stutter after the first 10 minutes.
• The laptop body is uncomfortable to touch around the keyboard.
• Random shutdowns under load, even at idle moments later.
• A burning or plastic smell from the vents.

If any of these match, stop heavy use and book a thermal service. Continuing to load a hot system is how a BDT 1,500 repaste turns into a BDT 15,000 motherboard repair.

Office and small business tip

If you run more than three PCs in one room, ambient room temperature is your enemy. A single split AC running 8 hours a day extends the lifespan of every device in the room by years. The math always works in favor of the AC.
