"I really don't understand the hype. Coming off of premium aio with minimal wiring, this thing is cheap, looks cheap, performs just fine but let's be honest anything 360 and above is overkill anyhow if youre just cooling a cpu... even at 25 percent, these fans were so loud. Like I use a full size sound bar for audio and this thing literally drown it out. All the fittings are plastic, if you want to run the pump, the fan on the cpu and the radiator fans at separate rates, you have to run like 4 wires off the face of your gpu all over your mobo, you can see through the faceplate on the cpu to the ugly magnet that holds it on. The fans are ugly. This is a perfect aio if you only have 100$ and plan on drowning out your whole family and everyone around you"

I couldn't be happier with this ARCTIC Liquid Freezer III. The ease of installation was a total breeze, which is rare for such a large AIO. It looks phenomenal in my white PC build and it worked perfectly on the very first try! Great quality and definitely worth it for the performance and aesthetics.tommy

Pros:- one of the top AIOs in terms of cooling performance- quiet- nice RGB- offset mount and thick radiator help cooling- long tubes so should fit into even very large casesCons:- not many cases support 420mm radiators and of those that do some as front mount only; double check!- the CPU mount has a good chance of blocking your top SSD, meaning you'll have to install the SSD first and if you want to replace that SSD you'll have a bit of teaar down/rebuild work ahead of you- for some boards, cannot install if the heatsink of the top SSD slot is too high without rotating the CPU mount 180- if CPU mount rotated 180 very difficult to get both sides to "catch" when installing (180 rotation also means VRM fan no longer in its ideal position)- might want to swap included fans out with yours that vibrate less at high speedNeutral:- about middle of the pack in terms of ease of installation: some have easier setups; some more difficultOverall:Absolutely amazing value for the money and often on sale for even less! Great performance in terms of both cooling and low noise, although a few other AIOs can do better. Most cases can accommodate the thick radiator (38mm versus the standard 25mm), but in some, you'll have a very tight fit. Confirm your case's measurements.The included fans are quite good but not as vibration-resistant as the best (e.g., Noctua) at high speeds. OTOH, there is no good way to avoid noisy fans if you truly insist on running above 60% to squeeze a degree or two more Celsius of cooling, which your CPU probably doesn't even need anyway,What Customers Talk About
