Best RAM Coolers and Heatsinks for PC Memory Cooling in 2018

Normally RAM or Memory does not require active cooling solution (i.e. fan) and not even heatsinks or heat spreaders if you are not going to overclock it. However, RAM can heat up a lot in some cases particularly during heavy overclocking or due to bad air flow in your case even when it has heat spreader installed on it. Overheating of RAM can cause system instability and crashes which can be very annoying for anyone. So, to overcome this issue you can use RAM Coolers to cool down your memory and keep their temperatures in check.

These RAM coolers come with a fan that blows air to the RAM modules and keep them cool even during heavy RAM usage or load. RAM Cooling results in stability during overclocking or when using Intel XMP profiles. These RAM coolers sit and clips on the DIMM side latches / locks and they are very easy to install and remove. Here in this post I am going to list down some of the best RAM coolers and RAM Heat spreaders that you can get if you are facing issues with RAM overheating.
