We are fortunate that today computing has progressed a lot and there are solutions for all tastes and budgets. Now it is no longer enough to have a good horse, now it must also be aesthetic. The composition, which is made in the form of thinnest liquid coolers and more specifically, are all in Ones, but are they better than air coolers?
The cooling liquid itself can have interesting aspects, such as better temperatures. First of all, this type of cooling is important for high-end processors, such as the Intel Core i9 and AMD Ryzen 9. Although, in most cases, they are a worse option than the typical tower-type heatsink.
They don’t let their temper down as much and are quieter
Many stories have been generated about these process heat dissipation systems (and also graphics cards). Usually, it is emphasized that they are more efficient in heat dissipation and that they generate less noise. The truth is that the RL will not always give us better results than the heatsink-type, and there are reasons.
The first system of fans, more specifically, in typology. Although you may not know, there are two types of computer fans: pressure and flow. Generally, flow rates are used more for RL and pressures for narrow heatsinks. The reason is the surface area that the air must cover. Block-type heatsinks are thicker than liquid-cooled radiators.
What is surprising is that both systems use fans, which are at the end, which allow for cooling. The problem, so to speak, is that one heatsink fan is equivalent to RL (more or less). The pressure of the spider is more noise than the floating fans, compared to one. But the more fans, the more noise.
In addition, pressure fans are usually more efficient at dissipating heat. They generate more air, so the temperature is reduced more quickly. Of course, there is even more surface area to cover than an RL radiator.
Actually, the problem is elsewhere.
It must be said that the biggest problem with RL is its simplicity. The custom liquid cooling system is complex and has different components, such as a separate pump and reservoir. AIO systems do not have a reservoir, so there is no “excess” liquid to compensate for the micro-evaporation that occurs through the pores of the tube.
Every plastic tube has pores and when the liquid evaporates very slowly and slowly, it is lost. In discovering (and according to use) the amount of liquid decreases and the circulation of the system increases. It forces the pump to a higher power and in the end to work, burn out or not do its job well.
It is a design flaw in all RL AIOs that results in a lifespan of 2-4 years (depending on usage). A large part does not have a filler cap to replace the loss of liquid. This simple element could make our liquid cooling last forever and it wouldn’t matter. In the end, the origin of all problems is not so far away.
I personally find AIO RLs to be interesting and useful. They are a good product, but they have a design and manufacturing flaw that, for me, makes it a terrible product. Curiously, the first prototypes of this cooling system had this cap that was lost over time.
