NZXT Kraken X73 RGB (CPU Cooler)
Talking about all the high performance of the CPU got the topic heated. Let’s cool it down with our most recommended cooler for 10th gen processors. Running all the latest games at the highest possible setting on the 8k will make the processor’s temperature rise. For our CPU’s temperature to be under control, we suggest equipping it with the best CPU coolers.
What can be better at cooling a processor than a radiator cooler? The recommended and the sleekest-looking cooler for our CPU is the NZXT Kraken X73 RGB. This cooler keeps the temperature under control along with giving an aesthetic look to your rig.
Who wouldn’t like to have an NZXT RGB cooler in their pc? All new 7th Gen Asetek pumps of this cooler provide better cooling and 800RPM, which means whisper-quiet performance. It comes with an 8-year warranty, the 3 120mm fans on the radiator are sure to keep the ventilation in good condition even in the worst possible scenario.
The rubber tubing is reinforced, making it further leakage-proof. The RGB and the NZXT logo give your rig a cool look and the temperatures are sure to stay under control because of its top cooling performance.

For running the games at 8k resolution and still getting the most FPS possible, RAM is a very important component. This can not be compromised. RAM is also responsible for your PC’s performance. These memory sticks will be crucial for running games at high resolutions and on the highest possible graphical settings. Featuring a completely exposed light bar with vibrant RGB LEDs, merged with the award-winning Trident Z heat spreader designed and constructed with the highest quality components, the Trident Z RGB DDR4 memory kit combines the most vivid RGB lighting with uncompromised performance.
This RAM will keep its own temperature under control even when used to its fullest. Getting 32GB of RAM is very important as running all the AAA title games at the highest possible setting uses a lot of RAM. It provides 3000MhZ directly to your computer, pushing performance to the extreme.
I won’t hesitate to say that it gives your build such an aesthetic look that you won’t find in any other. You get the highest build quality and performance along with that appealing look in one, which is why this is the suggested RAM. This specific RAM is also rated as one of the best available.

Yes, we are using an RTX 3090 for this build, but there are a lot of different versions of the graphics card available in the market. Choosing from one of these versions might actually be very overwhelming and confusing for most people as the difference is not very clear. So we suggest you the best available 3090 GPU in the market due to its certain features.
The MSI Gaming X Trio is the best choice for our build as we are going all out on this one. The features of this GPU are better than any other GPU available in the market and it just looks stunning. It will make sure you enjoy all your favorite games with a powerful graphics card that stays cool and silent.
Temperature control is very important in this build, as mentioned. Higher temperatures can actually make the computer’s performance worse, which we don’t want. This graphics card is the best-looking 3090 with RGB that is currently available in the market. The RGB and looks might not be important for some but it matters for most.
The 3 fans on this GPU keep its temperature under control with good ventilation systems. The case we will be using is also very compatible with this GPU. This graphics card might be a little more expensive than most, but it also provides you the highest MHz in any RTX.

NZXT H710i (Case)
We recommend the best-looking case with the best ventilation system and even a proper cable management system. The tempered glass side panel on this case will show off all your high-end components in your rig and the RGB will keep your aesthetic craving satisfied.
NZXT cases are known for their sleek designs and their best cable management system. Cable management actually makes a lot of clearance in your build, so you can easily show off your components while keeping them cool. Cable management is a big factor that most people find hard to deal with, but the NZXT has come up with a solution to ward off the issue.
The above-mentioned CPU cooler fits perfectly on the top of this case while showing the CPU meter on the CPU clearly and the RGB glow is also very prominent. Our RTX 3090 also has a lot of clearance space in this case so the temperature on our GPU will also remain normal.
For cable management, the opposite side of the case is equipped with the cable management bar, which will hold all the cables in position and they don’t hang above your fans. You can even show off your graphic card with a built-in mounting bracket for installing your GPU vertically.
