    Things to Consider When Buying a CPU Cooler for i9 9900K

    1. CPU Cooler Budget

    Having a spending range in mind can help you decide properly on the CPU cooler model that is right for you.

    Spending too little on it may get you an incompatible CPU cooler that is too weak for your processor. On the other hand, overspending may result in your having a cooler that is cut out for a better CPU than yours is -the money which you may have spent on another component.

    Once you take into account all the factors described below and explore them, you will get the idea of an approximate price for a CPU cooler with the decent build quality.

    2. What Is the Cooler For?

    The intended use for a cooler dictates which type you are to buy.

    It may be a computer with a high level of expected performance. It may be a computer set up on a budget or one that will be used for average performance, so a strong cooler isn’t necessary.

    It may also depend on the other computer components, such as in our case here. Now, we are looking for the best CPU cooler for i9 9900k processor.

    3. Air Cooling or Liquid Cooling

    This is one of the most important decisions to make. To make things clearer for you, here are the lists of pros and cons for both options.

    It can be noted that there are other cooling systems, usually based on these two main ones, that are far less efficient and will not be mentioned here.

    Air Cooler

    Pros:

    • A decent quality for price
    • Longer lasting than liquid coolers
    • Very little maintenance needed

    Cons:

    • Not suitable for computers that need extreme cooling
    • May be of a substantial size

    Liquid Cooler

    Pros:

    • Better performance than air coolers
    • Clearance issues not likely

    Cons:

    • Leaking risk
    • Need regular maintenance

    4. Thermal Design Power (TDP)

    This feature is also known as thermal design point/profile/parameter.

    When a PC works, its components get warmer. Under an intense workload, they can get quite heated. There is a maximum heat a component can withstand without getting broken.

    Put simply, TDP is the amount of heat a PC component (such as CPU or GPU) generates when it is under the maximum workload. It is stated in watts.

    Even CPU coolers have a TDP stated in the specification sheet. As a way to see whether a cooler is appropriate for a processor, you should compare the two numbers.

    A CPU cooler needs to be strong enough to cool the CPU when handling the heaviest workload. Thus, the TDR rating of the cooler should be bigger than that of the processor.

    Small, medium-sized, or big coolers are available for various processors.

    5. CPU Socket

    There is more than one type of socket that may be designed for a processor. Hence, your CPU cooler needs to have a proper bracket for it.

    Certainly, most producers of cooling systems will make them fit most CPU sockets.

    However, some CPU coolers fit only particular types of sockets, so checking that is an important part of choosing the best CPU cooler for your needs.

    6. Clearance Space

    You should mind whether your preferred CPU cooler fits physically into your computer case. This factor includes three aspects:

    • Height – There are coolers that are too tall for some cases. Check the height on the specification sheet and the RAM clearance of your computer case.
    • Bulkiness – If a cooler is too bulky, it will take too much space inside a case and other components won’t fit.
    • Size of radiator – Radiators come in many different sizes. So, maybe the size of the cooler in its entirety won’t be the problem as much as the size of its radiator. This goes especially for liquid coolers.

    7. Noise

    The cooler is the noisiest part of a computer, more precisely, its fans are.

    A smaller fan tends to be louder because it needs to make a lot of spins for a certain level of cooling. On the other hand, a bigger fan can spin more slowly for the same result and is thus quieter.

    Also, when we compare one fan versus a few, the cooler with a few fans will be quieter. The reason is that its fans, don’t need to spin as fast as the cooler with only one fan to produce the same result.
