High-performance CPUs generate a lot of heat so to keep them stable you are pretty much required to get a capable liquid cooler. Why not an air cooler? Are liquid coolers worth the extra expense? The short answer is yes. They provide better performance though it’s not always about keeping the temperatures of your CPU as low as possible. It’s a better idea to choose liquid over air cooling as it usually helps to keep your system more stable in the long run and can be less tricky to install.

If you decided that it’s time to eliminate the heat that’s dragging your CPU down and you wish to buy a liquid CPU cooler, there are a few things that you should consider such as:

1. Compatibility

Obviously, the first thing that you need to check is if the cooler is compatible with your system’s case. The radiator is an important component of a liquid cooler and they can be usually found in sizes ranging from 120mm to 280mm in length. You’re going to have check what is the maximum size of a radiator which can fit in your case and this is done by going through the case’s specs. Another aspect that should also be taken into account is the thickness of the radiator and whether you’d like to go for a push-pull configuration which will require more space.

2. Your needs

People can easily get tempted from colorful premium liquid coolers that advertise incredible performance and whatnot but the truth is that you need to analyze your particular needs very well before breaking the bank on a very high-end liquid CPU cooler. Like all PC components, you can find entry-level coolers but also some high-performance ones that come with a premium price. It’s fine if you can afford it but consider well if it fits your current system and usage of the CPU. Many manufacturers add features like LED lighting or built-in fan control which are more or less interesting but some people don’t really care about these. Instead, they try to find the best performance, the best bang for their buck. Even cheaper liquid CPU coolers can have a significant impact on your CPU temperatures when you’re upgrading from a stock air cooler.

If you have a general idea about how your future liquid CPU cooler should look like, it wouldn’t hurt to check out these products below. They have been analyzed very carefully and only selected if they can be truly considered worth the money. You can discover models suitable for a varied range of budgets and particular needs. If you are finally ready for dramatically lowering your CPU temperatures, getting a quality liquid cooler is a very smart investment.
