AIO ARE SIGNIFICANTLY BETTER THAN AIR COOLERS
You are switching your good trusty air cooler with your recently bought AIO, you install it, start the system, open AIDA64 and start a stress test. 21-21 ⁰C on idle and 45-50 ⁰C on stress. Maybe 20 30 degrees of improvement. That’s NOT true. As I said before, liquid based fluids take much more to reach the max temperature due to their nature (Hydro-electrical bonds).
Let me explain better: Every substance has a specific value that measures the amount of heat required to raise the temperature of the unit mass of a given substance by one degree. It takes the name of SPECIFIC HEAT CAPACITY [J/(g*⁰K) ]. Copper has a SHC of 0,4 units while H2O has 4.2. That’s more that 10 times higher. That means that water takes more time to raise and decrease his temperature and 10 or 15 minute of stress testing is not enough. With a watercooled system the minimum goes from one to one and a half hour. NOTE: I’m not saying that air cooling is better or equals to aircooling, it depends from a multitude of variables and models.
CUSTOM WATERCOOLING IS SIGNIFICANTLY BETTER THAN AIOs
Here is the same, testing has priority, and between an AIO and a Custom loop (with the same radiator and with the same fan and fan speed) there are only a few degrees of difference. People usually choose custom loops for different reasons (expandibility, aesthetic, to watercool also the GPU with a full size acrylic waterblock).
AIR BUBBLES IN THE LOOP WILL KILL YOUR PUMP
This is a partial truth, because massive air bubbles that goes constantly through specific types of pumps, can possibly kill them overtime, but with small ones you are totally fine. (AIOs also have in their loop small air bubbles most of the times)
WATERCOOLED BUILDS ARE QUIETER THAN AIRCOOLED ONES
That’s not always true. Watercooling loops have fans attached to the radiators, so if you have only one 120 rad the amount of noise compared to a great aircooler is almost the same. In order to reduce fan speed and noise you must add radiators, to increase also dissipation capacity.
WATERCOOLING IS THE BEST WAY TO COOL A PC
Well if you’re a daily user maybe YES. But in order to achieve extreme overclocking people cool their systems with LIQUID NITROGEN. There are international competition where hardware is pushed to the limit to get an higher, stable overclock, sign a world record, and make great benchmarks scores.
