Best AIO CPU Cooler Buying Guide:

The best CPU coolers are just as significant as other high end components. Whether it’s your earliest time building a PC or you’re looking to upgrade the components in your existing one. 

Be sure to allocate some of your budgets to getting one to keep that internals fine, cool, and performing optimally. After all, no one wishes to see their gaming PC accelerator when demanding tasks. It can go even worse, catch fire because they got too hot. 

Here are some of the noteworthy considerations you can check out before buying a CPU cooler:

Air VS AIO Coolers:

Liquid cooling is a very popular option for gamers looking to take their gaming experience to incredible results, with frames at high resolutions and maximum graphic settings enabled. Liquid coolers are also great in smaller form factor systems where large air coolers may not fit. AIO liquid coolers provide more cooling potential than many mainstream air coolers, which is great for powerful components and overclocking. 

Thermal Design Power:

The TDP, or Thermal Design Power, is a rating given to computer chips by manufacturers AMD and Intel that indicates their processor products’ power usage and cooling requirements. It can be used as an estimate for what your actual power draw will likely be when using it in all-core load mode. The TDP also has significance with CPU cooler manufacturers, who often give ratings on how much heat output from a chip they’re able to handle based on its specifications.

CPU socket:

There are so many CPU coolers out there, and it can be hard to tell which ones will work with your motherboard or processor. That’s why you should always check the compatibility before buying. Although most of the CPU coolers are compatible with all the latest LGA and AMD sockets. 

Noise Level:

You might not have noticed how loud your CPU cooler is until it starts to make a buzzing noise. Most CPUs don’t go over 60-70 decibels. Still, power users know the louder they can get their computer’s cooling fan running without worrying about overheating, the better performance you’ll have at top speed. But what we have suggested above has the lowest noise level of 20db with full power performance. 

RGB LED Lights:

We all know all these advanced, and new technical components have RGB lights in them. There is no direct or indirect effect of RGB lights over performance, but they are only a showcase or decoration. They are only there to enhance the aesthetics, nothing else. 

Conclusion

When shopping for a processor, most of the time they come in a box along with a heatsink or cooling block with a fan already in place. Many users discard that refrigeration and prefer to buy a separate one that is better. But not so fast. Since it has already been paid for – unboxed processors are cheaper but harder to find in stores – wouldn’t it be nice to give them a try?

The cooling that Intel and AMD include are usually enough to cool a processor that is not overclocked , although they can be louder than others that cost 15 or 20 euros. It all also depends on the PC case, how well it dampens noise, and how well you have the interior cooled. A better-than-normal cooler is provided with certain AMD Ryzen processors, which can be used for normal noise operation. Intel’s 8th Gen Core and later also feature better fans in the area of ​​noise, although they don’t work miracles in this area.

To choose a good air cooling or heatsink, you must first know the maximum height of the CPU fan that the case can install , and its dimensions. Above all, you have to trust where the power connectors of the board are located so that it leaves you space to put and remove the cables if you need it. Some fans are huge blocks that practically obscure the upper area of ​​the plates inside the case, rendering it inaccessible.

You also have to check that it does not collide with the memory sinks , if they have them. The assembly is usually quite simple in the basic ones, and the most expensive or heavy ones need to be secured behind the plate, but it is generally well explained in the product’s assembly manual. Some models even provide a longer-than-normal screwdriver or other material needed for mounting.
