Many installed users tend to prefer tower heatsinks when choosing CPU heatsinks, but we know that there is another type of heatsinks that are pressurized heatsinks, but unless it's a small case, basically no one chooses this so why not opt ​​for a pressure heatsink? Is heat dissipation effect of tower heatsink better than that of down pressure heatsink?

Introduction to radiator

The CPU heatsink transfers heat to heatsink cooling fins through silicone grease, copper tubes, bases, and other thermal media, and then uses fans to dissipate heat. From point of view of principle of operation, effect of heat dissipation may be affected by effect of thermal conductivity of heat transfer medium, as well as size and speed of fan.

Therefore, a good heatsink should have a smooth base, a heat pipe with high thermal conductivity, a good fin design (contact process, quantity, area, etc.), and a fan with a sufficiently high speed and a sufficiently large speed. But whether it is a tower radiator or a pressurized radiator, such a radiator can be made, but why do people prefer tower radiators?

A tower radiator at same price is better than a drain?

Yes, indeed. First of all, we can compare overall structure of heatsink with presser and tower heatsinks. It can be seen that size of radiator gap is very large, so in a small case you can only choose a pressure radiator. Both heatsinks are designed to be in direct contact with processor with four heat pipes.

Comparing thickness of two heatsinks, it can be seen that tower heatsink is about three times larger than down pressure heatsink, that is, when area of ​​the cooling fins is same, tower heatsink The area of ​​the heat dissipation fins of heatsink is about 6 times that of pressure radiator.

However, if you compare their bases, you will find that base, whether tower type or pressure type, is basically same, and area of ​​the heat pipe is also similar. There is no difference, which means that biggest difference between tower radiator and pressure-type radiator is total area of ​​the cooling fins.

Even without testing, we know that larger area of ​​the cooling fin, better cooling effect. In terms of contact between CPU and base, heat conduction efficiency is similar, but since tower heatsink has a large area, heat dissipation fins can dissipate heat faster and indirectly improve heat conduction efficiency between CPU and base.

Does a tower type have to be better than a push type for same price?

Tower type is generally better than presser type for same price, but it's not absolute. The direction of wind from tower radiator and lower pressure radiator is different. The tower heatsink blows sideways, while direct pressure heatsink blows directly onto CPU. While CPU generates a lot of heat, CPU is not only source of heat. source for motherboard. For example, heat generated by CPU power module is not small, and there are memory cards, etc., and tower heatsink can only manage air circulation, because it is blown from side, and cannot solve problem of heat dissipation, different from CPU, but downward pressure type is that it directly blows on CPU, so it also indirectly provides cooling conditions for other components such as motherboard.

When do you need a downforce radiator?

Large cases and high-end motherboards generally don't need a pop-up heatsink because high-end motherboards will have cooling modules for components that need to be cooled, so vertical heatsinks are best choice and only need to cool CPU. For motherboards with poor heat dissipation design, mid-range and low-end processors, and a small case, a pressurized heatsink can be selected.
