When choosing a RAM heatsink, consider whether multiple heat spreaders or a single heatsink is more practical. RAM coolers with fans require power and vary in airflow. Quality materials and craftsmanship can affect performance.
There are a number of options available when purchasing a random access memory (RAM) heatsink, and most of them have to do with performance. A quality RAM heatsink should be able to quickly transfer heat from the memory to keep it from overheating. While this is often easier said than done, the overall size of the RAM heat sink also plays a critical factor as many memory sticks are often found within a computer system with very little space between them. Some coolers will cool multiple sticks of RAM at once, while others are designed to be installed directly on each memory stick. Actual fan systems can also vary greatly between budget and high-end RAM cooler models, which usually accounts for the large difference in price.
When comparing RAM heat sink designs, the first choice a consumer has to decide is whether multiple heat spreaders or a single heat sink would be more practical. Keeping memory fresh can improve performance by up to 30% in many computer systems, and the overall size of the system often decides which technology would be a better fit. Heat spreaders are often sufficient within large, well-ventilated devices that already have good airflow within the system, while a true RAM heat sink would provide superior ventilation within smaller systems and compact. Many laptops and micro computers fail due to this oversight, simply because there isn’t enough room for air to circulate inside.
When choosing a RAM cooler with fan, it’s important to consider a few options within the various models. The fan itself will require electricity directly from the power supply or motherboard, so checking that the required input is available will ensure compatibility. Additionally, the amount of power required will also vary significantly, and many premium RAM heatsinks are designed to be powered only by high-power supplies. When the system in question already has numerous fans and other optional devices running, adding a RAM heat sink may not even be possible without upgrading the power supply.
Another aspect of fan-based RAM heat sink types is the amount of air they move through the system, with the better models providing the greatest airflow. Price alone is often not indicative of this feature as many generic models work very well, with the only noticeable difference coming from the quality of materials or craftsmanship. Consumers should manually check how much air each RAM cooler is designed to supply for various workloads, as many of them can be programmed to spin at a higher RPM when the RAM gets too hot.
