This article will discuss the TDP of the 11900. Additionally, we will provide recommendations for compatible CPU coolers, motherboards, and memory.
Intel CPU specifications indicate this power dissipation number as "Processor Base Power."
The Core i9-11900 has a TDP of 65 watts.
Check out our Recommended LGA 1200 Coolers below.

A CPU cooler's TDP (Thermal Design Power) rating indicates how much heat it can dissipate in watts. If the cooler can't keep your CPU cool enough, your CPU may throttle (slow down), and your cooler will constantly run at full speed.
Intel CPU specifications indicate this power dissipation number as "Processor Base Power" and "Maximum Turbo Power."
The Core i9-11900 has a TDP of 65 watts.
A CPU cooler can still work with a lower TDP rating than the TDP of a CPU. However, the CPU will eventually throttle itself to a lower frequency to allow itself to cool.
The CPU may not achieve or maintain maximum turbo speeds without adequate cooling.
Types of Coolers
Air coolers use a combination of heatsinks and fans. They are the cheapest, but also the loudest.
A Closed-Loop Cooler (CLC), also called an All-in-One (AIO) cooler, is a type of liquid cooler. All-in-one liquid coolers provide a more straightforward setup in a single pre-built package.
Liquid cooling can provide even better TDP performance at lower noise levels but are more expensive and take up more room. The noise level and ability to cool your CPU will depend on the liquid cooling solution's radiator size and the number and size of the fans.

Open-Loop Coolers are also a type of liquid cooler, except you construct them yourself. They allow for more flexibility in building your perfect cooling solution but can also be more complicated to set up. Open-loop systems give you the flexibility to cool additional devices, such as your graphics card's GPU.
More fans typically mean better cooling. However, they also mean more noise.
Larger fans are typically quieter than smaller fans, as they can move the same amount of air at lower speeds.
If a cooler is struggling to cool a CPU, it will run at its maximum speed, which will be louder.
Fan noise levels are measured a dB. Lower dB values are quieter.
You can often configure your motherboard's BIOS to use specific fan speeds at particular temperatures. This configurable fan speed allows you to have a near-silent computer while your computer is idle.
CPU coolers can have various mounting brackets to work with different socket sizes. Make sure that your cooler comes with a compatible mounting bracket.
The easiest way to find a CPU cooler that will work for your computer is to search by socket type. For example, the 11900 uses an LGA 1200 socket, so you would search for an LGA 1200 CPU cooler.
In some cases, such as when a new socket size is released, there may not be many compatible coolers. In these cases, you can often purchase a separate mounting/retention kit to work with the new dimensions.
Before buying the biggest cooler possible, ensure that your case and motherboard configuration have room.
Also, ensure that other components on your motherboard won't interfere due to size constraints. For example, do your memory modules (DIMMs) have tall heat spreaders?
Dual-fan coolers often take up quite a bit of room. Liquid cooling solutions typically position fans at the top or bottom of the case.
Some CPU cooler fans come with LED lighting. Similarly, liquid cooling pump heads can also come with LEDs or even LCDs!
If you want to turn off the lights when they get annoying, make sure your CPU cooler has that option.
In general, air-based coolers will be lower cost than liquid cooling systems.
CPU coolers that support a higher TDP are also typically correlated with a higher price.
The more advanced lighting features tend to also come at an extra cost. You can decide between a practical, low-cost solution and a dazzling light show.
Locked Intel CPUs may come with a stock CPU cooler. These CPU models do not have a "K" in the name. While stock coolers will prevent your CPU from overheating, your CPU will throttle its performance during games and other intensive tasks. Higher TDP coolers will keep your CPU at turbo speeds for longer durations. Stock coolers are often quite loud at their maximum speed.

For Intel's 11th generation Core i9 11900 processor, you'll need a motherboard with an LGA 1200 socket and a compatible 500-series or 400-series chipset.
Motherboards for Intel processors are made with chipsets provided by Intel. Each chipset offers a unique set of capabilities. However, motherboards must explicitly support features and capabilities for you to use them. Verify that a motherboard supports the features and capabilities you desire.
The lack of a "K" suffix in the model name 11900 means it doesn't support overclocking. Because of this, there is no need for you to use the top of the line Z590 or Z490 chipsets which support overclocking. Instead, you can use a motherboard with Intel's other 500 or 400-series desktop chipsets listed below.
For compatiblity with Intel's 11th generation Core processors, you can use any of the 500-series chipsets: Z590, H570, B560, H510. These are roughly sorted from most to least functionality. The W580 and Q570 chipsets are also compatible, but are intended for workstation and business use cases; their availability in stand-alone motherboards is limited.
While the budget-friendly 400-series B460 and H410 won't work with the 11th generation Core processors, the Z490 and H470 400-series chipsets are compatible. However, these chipsets were originally designed for the 10th generations Core processors, and will limit the capabilities of your system. The W480 and Q470 chipsets are also compatible, but are intended for workstation and business use cases; their availability in stand-alone motherboards is limited.

Before purchasing memory, review your motherboard specification to verify which speeds are supported. For example, if a DDR4 motherboard stated that it supports "DDR4 3400(O.C.) / 3333(O.C.) / 3300(O.C.) / 3200 / 3000," that would mean that it could support DDR4-3400, DDR4-3333, and DDR4-3300 with memory overclocking, and DDR4-3200 and DDR4-3000 at stock speeds. Motherboard specifications also indicate the maximum capacity per stick of RAM (DIMM) and across all slots.
