How to Cool Down a High CPU Temperature

The Central Processing Unit is the brain of your PC. It calculates millions and trillions of data every second. Unquestionably, this load will produce heat that can damage the sensitive electronic components if the temperatures are not kept under control. This necessitates the use of processor coolers.


The processor cooler sucks the heat from the processor and dissipates in the air keeping the temperature under control. When we overclock the processor, the temperatures increase even more necessitating the use of a better cooler. 

There are two types of processor cooler available in the market i.e.; Air Coolers and Liquid Coolers. Both are effective in cooling the processors – liquid coolers are slightly more effective and if you are buying a top-end processor like Intel Core i7/i9 or a Ryzen 3900XT or 5800X or 5900X you can opt for a liquid cooler to get the best cooling.

Also, if your PC cabinet is not too big you may want to check the height of the cooler before purchasing. Liquid coolers with a single fan are compact and can usually fit in most cases.

Too Much Dust

Cleaning out your computer can do wonders for the temperature gauges. If your fan speed sounds too high, you may need to open your PC and clean it out.

Too much dust can clog fans and heatsink fins, but fortunately, cleaning the inside of your computer is easy: Ground yourself by touching metal to avoid electrical discharge to computer parts. Using compressed air from a 6-inch distance, blast away clumps of dust from fan blades, the power supply, motherboard, and all other components. For hard-to-reach places, use a Q-tip dipped in >90% isopropyl alcohol.

Reapply Thermal Paste

Thermal paste fills in the gaps between a CPU processor and the heatsink and aids in efficient heat transfer. Running a CPU with no thermal paste is like driving a car without oil. And what happens when you ignore obvious warning signs, like a check engine light? Instant engine failure.

Here’s a quick guide on how to apply thermal paste to a CPU:

To check if your CPU needs new thermal paste, locate the heatsink and remove it from the processor. Wipe off any excess paste and squeeze a pea-sized amount of paste onto the processor. Place the heatsink back on the processor (which will evenly spread the paste outward) and monitor the temperature over a few days using Speccy.
