Overheating is a silent killer of computers. It doesn't break hardware instantly but gradually: first the PC slows down, then gets noisy, then starts shutting off, and eventually the graphics card, motherboard or power supply fails. The good news is that overheating can almost always be fixed — and fixing it costs far less than buying new parts.
What happens to an overheating computer
Modern processors and graphics cards protect themselves: when they reach a critical temperature they lower their clock speed, which is called throttling. The computer doesn't burn out, but it can lose up to half its performance. Games stutter, video renders take twice as long, the browser lags. If cooling can't cope even at reduced speed, an emergency shutdown kicks in.
The worst part is the long-term damage. Every extra 10 °C roughly halves the lifespan of electrolytic capacitors. Solder joints under graphics chips suffer from constant heating and cooling cycles, and fans running flat out wear out faster. In a Tbilisi summer, when rooms reach 30 °C or more, the problem becomes especially acute.
Signs of overheating
- CPU above 85 °C or GPU above 80 °C under load;
- loud fans even during simple tasks;
- frame rates dropping 10–20 minutes into a game;
- sudden shutdowns or restarts under load;
- hot, dusty-smelling air from the case;
- on-screen artefacts such as stripes or coloured dots.
Why computers overheat
Dust on heatsinks and fans is the number one cause. Dried thermal paste loses conductivity after 2–4 years. Poor case airflow — fans working against each other, or too few of them. A weak cooler not designed for a powerful CPU. Location — a PC inside a closed cabinet, next to a radiator or in direct sunlight. Worn fans spinning slower than they should. Often several of these factors combine, which is why we measure before changing anything.
How we fix overheating
- Measurements. We record temperatures and clock speeds under a stress test as a baseline.
- Cleaning. Full disassembly of the cooling system and cleaning of heatsinks, fans and filters.
- Thermal interface. New thermal paste on the CPU and GPU and, where needed, new thermal pads on graphics memory and power stages.
- Airflow optimisation. Arranging intake and exhaust fans correctly and tidying cables.
- Cooling upgrade if required: a stronger tower cooler, extra fans or a better-ventilated case.
- Final measurements. We show you the result — typically 15–30 °C lower.
We recommend servicing the cooling system before summer, especially for gaming PCs and machines that run around the clock. A short visit in May is far cheaper than replacing a graphics card that cooked itself in August.
