Why your computer needs a cooler?
When you use your computer the CPU emits heat and this heat becomes much more when CPU has to do computation heavy tasks like gaming or video editing. If this heat is not dissipated quickly it can cause damage to the CPU itself and also other parts of the computer. Especially in a country India where temperatures remain high for most of the year you should keep an eye on the CPU temperature.
Why you need liquid cooling?
Air coolers do good enough jobs in normal use cases like browsing, social media, emailing, etc. but if you are using your computer for gaming or video editing CPU runs at higher speed and that too for longer periods. Liquid cooling is arguably way more efficient in dissipating that heat. If you are overclocking your CPU then liquid cooling is a must. You don’t want your CPU burning in flames.
