Iceberg IceSLEET X6 Thermal (Best Aesthetic CPU Cooler)


Iceberg thermal IceSLEET X6 Intel & AMD is the last entry on the list of best CPU coolers and brings absolute aesthetics into role play.

Shell of an iceberg

You must have never seen anything like this before, since the product is one-of-a-kind. Iceberg shelling is used for the architecture and design of the cooler, giving it a one-of-a-kind and unrivaled appearance. To be honest, this cooler is aimed for people who want to put in unique goods, whether they are costly or inexpensive.

Responses that are generated automatically

The cooler has an AI built in that monitors the environment and the temperature of the chipset. In essence, it controls the fan curve by determining the necessary threshold.

What should you consider before buying the best CPU cooler?

TDP (Total Daily Power)

This is where the complication begins. But why is that? Because the thermal design point is a method of estimating the average dissipation of heat from a component, it may not be as simple as it seems. Here’s how it goes: Assume you have a CPU with a 300 TDP (thermal dissipation rate) and a CPU cooler with a 320 TDP. So, what do you think is going to happen? Surprisingly, the CPU cooler will not lower the temperature, but will, in fact, raise the total temperature of your CPU.

Because the CPU cooler’s TDP is greater than the CPU’s, your cooler is functioning as a warmer. As a result, you should use CPU coolers with lower TDP values than your present processor.

Compatibility with sockets

It’s the most essential consideration since you’ll always need a CPU cooler that fits snugly on your processor. To cut to the point, vendors often send out stock coolers so that the customer does not have to deal with compatibility issues. But what if you’re replacing a CPU cooler? Then you have to be cautious about where the AMD or Intel socket is located. Pose questions to yourself and investigate the options for the finest CPU Cooler.


People are stubborn when it comes to research, therefore it’s the most overlooked aspect. Let’s pretend that a $200 CPU cooler performs identically to a $100 cooler in terms of RGB coverage. So, what are your options? According to the renowned statistics, the likelihood of individuals chasing after an expensive cooler is at an all-time high. It’s all due to marketing tactics, which you should be aware of.

Before buying any cooler, it is usually necessary to establish a margin. Liquid coolers are without a doubt costly, but their performance ratio is what makes them stand out in the pooler. It’s just incorrect to compare an air cooler to a liquid cooler. In any case, before buying any kind of cooler, make sure you have a clear budget in mind.

Liquid coolers vs. air coolers

For years, there has been a heated discussion, and to be honest, nothing has been put into perspective. Some enthusiasts favor air coolers since they need less power, while the other half always choose liquid coolers for two reasons: first, liquid coolers are the way to go if you are into extreme clocking, and second, they are more attractive.

Basically, if you want the best performance and are willing to pay a hundred dollars or more, the liquid cooler is the way to go.

Sound Pressure Levels

When I suggest that sound levels should be disregarded, believe me. No one like the sound of jets in their computer cases, particularly if it’s an air cooler. Because the primary goal of liquid coolers is to restrict the greatest amount of heat lost, they may be as noisy as air coolers.

140mm fans, or as you increase in height, are usually noisier. To find something in the middle, make sure that number one fits on your cooler and that number two is enough for temperature decrease. In summary, choosing CPU coolers is a trial and error process since what is noisy for me may not be loud for you. So don’t give up!

Final Thoughts

I hope you enjoyed the post; I did my best to provide all of the necessary information in the most thorough manner possible. It’s also worth noting that the list is not exhaustive and may grow in length as a result of current technology advances. So, yes, there are still hundreds of good CPU coolers available. What sets these entries apart is that they were subjected to extensive stress and testing before being given to the readers.

If you ask for my opinion, I would suggest Corsair liquid coolers since they are incredible and flexible in every aspect.
