Benchmarks Of The Best 240mm AIO Coolers
Knowing a CPU cooler’s thermal performance is the most important factor to consider before making a purchase decision. Therefore, after testing various coolers, here are our findings of the best 240mm AIO coolers compared to their competition under similar circumstances.
Why We Didn’t Go For These 240mm AIO Coolers
Our hardware experts have tested countless 240mm AIO coolers, but here are a few honorable mentions that didn’t make the cut for our list and why:
- NZXT Kraken Z53 RGB: A higher price for lower performance makes it a less viable purchase.
- DeepCool Castle 240EX: It has an older generation pump, making it less suitable for the latest high-end CPUs.
- EK AIO 240mm D-RGB: It has been discontinued and doesn’t support LGA 1700 right out of the box.
How We Picked & Selected The Best 240mm AIO Coolers
When it comes to choosing an AIO for your CPU, we always advise our users to consider all factors before making a decision. Choosing an AIO cooler can sometimes be difficult due to the variety of options available, but don’t worry; we’ve collected a list of buying recommendations to help you make an informed decision.
- Socket Compatibility: Every CPU has a different number of pins, meaning a different socket size. Before choosing a 240mm AIO, make sure it supports your CPU socket. Buying an AIO with the wrong CPU socket compatibility will not work. To check the socket compatibility options for your preferred cooler, visit the manufacturer’s site.
- TDP: Knowing your preferred AIO cooler’s Thermal Design Power is another important factor, as you don’t want the AIO’s TDP to be lower than the CPU’s. Otherwise, you won’t be able to cool your CPU correctly, leading to thermal throttling and lowering your PC’s performance.
- Noise Levels: Sometimes, some users prefer dead silent PCs; that is why we always say to make sure to do your research before purchasing a product with so many moving parts. AIO coolers contain fans and pumps that tend to make a lot of noise at times, and lowering RPM speeds reduces thermal performance, too.
- Aesthetics: In the end, you can always go for good looks. 240mm AIO coolers are available in countless shapes and designs, from the good-looking Corsair 240mm radiators to the decent and silent be quiet! You can always choose the AIO that best suits your personality.
