Thermaltake Water 3.0 Ultimate AIO CPU Cooler Review

Bigger is always better and Thermaltake keeps with that thinking with its Water 3.0 AIO (All-In-One) CPU cooler. Thermaltake expands it radiator system to an impressive 360mm's worth of liquid cooling. What is probably most impressive though is it does not have a ton of other generally useless blinky light features.

Results: Temperatures

For our stock testing our i7 4770k will be kept at 3.50 GHz with a minimal 1.00v. For overclocked CPU testing, we will be running our CPU at 4.4GHz with 1.25v. Idle temperatures will be recorded after a twenty minute period of inactivity. Any fluctuation during the last sixty seconds will reset the timer for an additional five minutes. Load temperatures will be recorded after a twenty minute period for air cooled systems, and 30 minutes for liquid cooled systems, at 100% load. To obtain this load we will be using AIDA64 Extreme Edition v3.00.2500. Any fluctuation during the last sixty seconds will reset the timer for an additional five minutes.

Please note we start our charts at 25C which is the ambient temperature at the time of testing. Since we are not testing an active cooling system such as a chiller or Peltier cooler, it is impossible for the temps to be less than ambient. This is why we start our charts at 25C.

At stock settings the Water 3.0 doesn’t do much to impress. It finds itself in the middle of the crowd. Turning the fans up to max helps the situation a bit but not enough to make the top five. But really, running this thing with a stock clocked CPU? Absurd.

Now this is more like it. A lot of voltage and a lot of heat combine to show us what this Water 3.0 Ultimate can do. Clearly, taking the straightforward approach has worked for Thermltake. Using nothing but a more fans and more radiator the Water 3.0 Ultimate is able to demolish the competition and take the top spot. Turning the fans down to the lowest setting makes the unit whisper quiet. It does sacrifice a bit of performance but considering how quiet the unit is, we are thoroughly impressed.

Sound

To test the sound output of the fan we first start by disabling all other fans in the PC. We place our meter approximately four feet away from the test system and then collect the dB data.

With the fans set to the highest speed these make a lot of noise. As I sit here typing this, I have the fans at this setting and it’s noticeable. This is not the setting you want to use for prolonged periods of web surfing or other quiet activities. It becomes very annoying after a while but would likely not come to mind while gaming.

But once you turn the fans down all that goes away. In fact, the fans are so quiet you would be hard pressed to know if my PC were even running. The fans are nearly silent and can easily push enough air to keep my CPU cool.
