Pros:

They have nice aesthetics. They look far better than air coolers as air coolers look clucky and resemble a chunk of metal hanging off the motherboard.

Some 240MM AIO coolers can outperform the best air coolers. This cooling performance means you can achieve decent overclocks as long as your whole system is correctly ventilated.

In terms of installation, AIO coolers are easier to install than custom water cooling loops

Cons:

They’re more expensive than their air cooling counterparts.

They’re louder than air coolers due to having pumps and fans.

The decent cooling performance comes from partially the AIO pump which is able to displace coolant far better than the previous versions, and other 240MM AIO coolers. Also, the Aer p fans are great at operating silently, whilst being great at cooling the liquid in the radiator.

You’re able to fine-tune the performance inside the CAM software to enhance cooling performance in certain situations.

If you take full advantage of the CAM software, you can take control of the RGB, and make use of all the RGB lighting presets it has. Preset Modes: Fixed, Breathing, Fading, Pulse, Spectrum Wave, Marquee, Covering Marquee, Alternating, Loading, Heat Exchange.

Installation was made to be as painless as possible. The instructions it comes with are very user-friendly.

Altogether, you get a cooler that offers decent cooling for your dollar, and that’s quite rare for AIO coolers.

The EVGA CLC 240MM is a well built & overall strong CPU cooler. EVGA has an efficient cooling block for increased flow rate and heat transference.

Variable controlled fans mean that the fans are controlled by the temperature of the CPU. If the CPU is hot, then the fans will operate as a higher RPM. On the contrary, if the CPU is cool, then the fans will operate lower.

Noise levels can be extremely low because of the nano bearings the fans utilize. As long as the CPU isn’t hot to the point the cooler cannot keep up, noise levels will remain low. Make sure your PC is properly ventilated, and you’re properly exhausting hot air.

Build quality was EVGAs top priority when designing this cooler. They’ve equipped the tubing with sleeves to enhance the durability. On top of that, the fans are highly durable because of the Teflon nano bearings. Vibrations are kept to a minimum, which increases the lifespan of the entire cooler.

EVGA CLC 240MM | PROS & CONS

Pros
  • 100% copper base. Good heat transfer.
  • Good bang for your buck.
  • Extremely durable.
  • Good cooling performance.
Cons
  • Manual could be better for installation purposes.
