FPS drops after ~20 minutes
A CPU or GPU that starts a session at full clock speed and settles lower as it heats up is throttling, not aging. A well-cooled PC holds its clocks for hours.

Why does my gaming PC throttle mid-game in Singapore?
If your FPS drops after 20 to 30 minutes, your fans get louder as the session goes on, or you hear a faint coil whine under load, your PC is very likely throttling — cutting its own performance to stay within a safe temperature. Singapore's climate makes it worse than most places. Here's why, and what fixes it.
THE SYMPTOMS
How to tell you're throttling, not just "getting old"
Coil whine that gets louder under load
A faint high-pitched whine from the GPU or power delivery area is often just electrical noise, but if it gets noticeably worse as the card heats up, thermal stress is a contributing factor.
Fans ramping to full speed at idle-ish loads
If your fans sound like takeoff during games that used to run quietly, your cooler is working harder to move the same amount of heat — a sign airflow is restricted.
THE SINGAPORE FACTOR
Why this happens more here than in drier climates
Singapore's year-round humidity and ambient heat mean two things for a PC: dust sticks to fan blades and heatsink fins more readily in humid air, and the air a cooler pulls in to begin with is already warmer than in temperate countries. A cooler that would comfortably handle a CPU in a 20°C room has less thermal headroom to work with when room temperature is closer to 28–30°C. Add months of accumulated dust restricting airflow through the heatsink fins, and clock speeds start dropping to keep the chip within its safe limit — that's throttling.
WHAT ACTUALLY FIXES IT
Cleaning fixes throttling caused by dust and dried paste
If your PC is more than a year or two old and has never been opened, dust buildup and drying thermal paste are the most likely causes — not failing hardware. A proper deep clean removes the cooler and fans, clears the heatsink fins, and replaces the CPU thermal paste, which naturally dries out and loses effectiveness over time. If throttling continues after a proper clean and repaste, that points to a hardware issue needing diagnosis instead.

Why does my gaming PC throttle mid-game in Singapore?
Gaming PCs in Singapore commonly throttle mid-game because dust buildup and Singapore's high humidity and ambient heat reduce cooler efficiency faster than in drier climates, and DreamPC's $128 Deep Clean addresses this with a full teardown, fresh repaste and load testing.
