The CPU cooler is an essential component for any computer because it aids in keeping the processor at safer temperatures and preventing overheating. Overheating must be avoided because it can slow down the CPU’s performance and cause permanent damage.
Several key factors are essential to determine if you can replace a CPU cooler without removing the motherboard. The cooler’s size, the motherboard’s orientation, and the mounting system used for attaching the cooler are all critical factors for determining that.
Larger coolers would require removing the motherboard. Some motherboards also feature connectors, making accessing the processor complicated without removing the board itself.
Long story short, replacing the CPU cooler without removing the motherboard is possible sometimes, but extra caution and effort are required to prevent damage. The best way to cautiously replace the cooler is to carefully follow the instructions provided in the motherboard and the cooler’s manuals.
In most cases, removing the motherboard before replacing the cooler would be ideal.
How to Replace a CPU Cooler Without Removing Motherboard?
As stated above, removing the motherboard to replace the CPU cooler is recommended for safety and cleaning reasons. Still, if you want to replace the CPU cooler without having to remove the motherboard, there are a few steps to follow:
- Disconnect all cables and peripherals from the motherboard.
- Remove both the side panels of the CPU. Removing the right-side panel can help navigate the unscrewing.
- Remove the cooler carefully by unscrewing its screws or clips. If the cooler is a stock cooler, it may rely on a retention clip. To remove the clips, gently lift them on either side of the cooler.
- Before installing the new cooler, clean the CPU. Use a lint-free cloth alongside isopropyl alcohol. This will help remove dust and the old thermal paste from the CPU’s surface.
- Apply the new thermal paste on the CPU.
- Place the new CPU cooler on the CPU with precision. Make sure to align it correctly with the CPU before mounting it.
- Attach the cooler by screwing it properly or attaching retention clips (depending on the cooler).
- Connect all the cables and peripherals to the motherboard again.
Note that replacing a cooler without removing the motherboard is a risky process that needs to be handled carefully to avoid permanent damage to the motherboard and the CPU. We recommend getting assisted by a professional for this process.
What CPU Coolers Can Be Installed Without Removing Motherboard?
There are a few types of CPU coolers that can be installed without having to remove the motherboard, including:
- Stock coolers: The most common type of CPU coolers. They are low profile and come with CPUs. Their design is minimalistic, so they are easy to install and mainly do not require a retention clip.
- Low-profile CPU coolers: Similar in size to stock coolers, these are bought separately from the CPU. They are small and slim and are made to fit tighter spaces. Since they do not require a lot of room, they can easily be installed without removing the motherboard.
- Air CPU coolers: Air coolers rely on a heatsink and a fan to dissipate the CPU’s heat. It is not uncommon to find smaller air coolers that can easily fit into the motherboard without removing it.
- All-in-one liquid coolers rely on a combination of pumps, radiators, and fans to tackle the CPU’s heat. They are prominently more efficient than air coolers but are also more difficult to install. Some all-in-one liquid coolers are made to be installed without removing the motherboard, but most are big enough to require removing it.
Additionally, one must not forget to assess the compatibility of the cooler and the motherboard.
How to Remove Motherboard from the Case?
If the CPU coolers involved in the scenario are too large, you might have to remove the motherboard to properly replace your cooler. Here are the steps to remove the motherboard:
- Make sure to shut down your computer.
- Disconnect all the peripherals and cables from the motherboard.
- Remove both side panels of the case.
- Look for all the screws the motherboard uses for mounting. They are mainly located around the board’s edges but can often be around the center.
- Remove the screws or clips from the motherboard. Some cases use a backplate that needs to be removed before the motherboard.
- Ensure all the screws are removed, and gently lift the motherboard.
- Replace the CPU cooler by following the steps already listed in the article.
How to Reinstall Motherboard on the Case
The following steps can help you reinstall the motherboard on the case:
- Organize and clean up the case before installing the motherboard.
- Align the motherboard with the case’s standoffs and mounting hardware, and then attach it.
- Mount the board on the case by using the provided screws or clips. Make sure to tighten the screws evenly. Do not overtighten either, as that could damage the motherboard.
- Once the motherboard is installed, start mounting other hardware like power supply, RAM, GPU, and SSD/HDD.
- Make sure to follow the instructions for adequately attaching each component.
- Connect all the peripherals, data cables, and power cables to the motherboard.
- You must check the manual provided alongside to locate all the switches for case headers. Plug them accordingly before powering the PC.
