About Iceberg Thermal

Iceberg Thermal is an American company based in Tempe, Arizona. I’ve previously tested their G4 Silent Air cooler and found it to be a great value with good cooling capacity and whisper quiet noise levels. Today we’ll be looking at Iceberg Thermal’s higher performance air cooler – the X7 Dual.

While on the books Iceberg Thermal was only founded 3 years ago, their team of experts have over 15 years experience designing cooling products. Their companies lineup currently includes fans, air coolers, thermal pastes, and more. Their expertise doesn’t end with consumer products – they are also experts in industrial cooling solutions with some of their clients including BMW, Panasonic, ASUS, and many other well known brand names! I briefly spoke with IceBerg Thermal’s CEO at CES 2023, you can read more about that at our previous article: A new player enters the cooling game: chatting with Iceberg Thermal at CES 2023


In the past I’ve mentioned how my past testing of coolers had focused on Intel CPUs because they were the most challenging to cool and also consumed the most power. When Alder Lake was released, I noticed that the thermal difficulty of cooling the 12900K was more difficult compared to prior generation products – only a few coolers were able to keep it under TJMax.

Intel’s i9-13900K and AMD’s Ryzen 7 7700X CPUs can be even more difficult to cool in heat intensive workloads – and this trend is likely to continue with future generations of CPUs. As CPUs continue to shrink in size, thermal density rises, increasing the difficulty of cooling. Indeed, it is no longer worrying to run a desktop CPU at it’s peak temperature – it is to be expected in intense workloads (for example: rendering) without power restrictions or undervolting.

2 fans – 1x 140mm, 1x 120mm

There’s more to a cooler than just it’s heat sink, the fans paired with a cooler have a direct impact on total cooling capacity and noise levels.

Included with the X7 Dual includes 2 fans of different sizes : 1x 120mm and 1x 140mm fan.

Iceberg Thermal advertises the following with these fans:

  • Mechanical Automatic Start/Stop
    • Creates a quiet environment and reduces power consumption, decreasing heat, to create a more comfortable work/play experience. When the fan is in off mode it goes silent, until the PWM duty cycle reaches 21% loading.
  • Gleaming ARGB Control Function
    • ARGB function allows YOU to customize the colors you want gleaming from your CPU cooler.
  • Dual Heat Sink Towers with Dual Fans for DOUBLE the Effectiveness
    • Two heat sinks connected to the heat pipes with one 120 mm fan and one 140 mm fan. This provides the pinnacle in push-pull technology, creating optimum airflow, allowing you to overclock!

AMD Ryzen 7 7700X Thermal and Acoustic Results

As I’ve only had time to complete testing of eight coolers on AMD’s AM5 platform, the data I have is currently limited. This will grow as I continue to test coolers.

For thermal results, I’ve tested the CPU in three configurations:

  • At the default power limits
  • With a 95W PPT enforced
  • With a 75W PPT enforced.

Noise Normalized Results

Performance only scales by a limited amount with improved cooling capacity with Ryzen 7000. This also means that there is less of a benefit to running fans at higher performance levels. As such, it can be useful to see how coolers compared when noise normalized for quiet, silent operation.

In this noise normalized scenario for silent performance, the IceSleet X7 offers a moderate increase in total cooling capacity vs lower end air coolers. At 111 vs 107 watts, we’re looking at a 3.7% increase in total cooling capacity vs DeepCool’s midrange cooler offering when fans are set to run quietly.

Default Power Limits

At the default PPT of 105W, the most intensive loads can be difficult to cool and result in the CPU running at TJMax with anything less than the strongest coolers. DeepCool’s LT720 and EKWB’s EK Elite coolers are the only two I’ve tested (yet) which can handle that much heat. As such, we’ll be looking at two metrics in this situation where coolers run with the CPU reaching TJMax (95c): Noise levels and watts cooled.

Iceberg Thermal’s IceSleet X7 does well here, cooling just over 10W more than their G4 Silent air cooler and a few watts more than DeepCool’s AG500.

At 48.7 dBA, the total system noise levels are certainly audible but not what I would consider loud.

Some of y’all might notice that the graph starts at 36 instead of zero – this is because my sound meter cannot measure noise levels lower than 36 dBA. Since that is the noise floor of this meter’s recording capabilities, 36 dBA is the “zero” for our testing purposes.

For those concerned that this might distort results – there’s no worry. If anything, the graphs above will minimize the differences in noise levels because dBA measurements are logarithmic – which means that the perceived total volume doubles every couple of dBA depending on the sensitivity of your ears.

BeQuiet! made a video explaining this relationship better than anything I could ever put into words, it’s embedded below.


Imposing even a minor power consumption limit on AMD’s Ryzen 7700X reduces cooling difficulty dramatically resulting in the ability to easily to cool the CPU under TJMax (95c), as such in these situations the total noise levels are more important. It’s also important to test in these TDP restricted situations, because most “real life” workloads will not push the CPU to it’s limits.

The results in this scenario show that most air coolers will likely perform similarly in this scenario, with Iceberg Thermal’s X7 matching the results of DeepCool’s AG500. When tied to my motherboard’s default fan curve, it was one of the louder offerings in this scenario.


Lowering the PPT to 75W further reduces the cooling difficulty, bringing CPU temperatures down to 40C over a 23C ambient temperature. The thermal results for this low power result were interesting, with the IceSleet X7 slightly outperforming Fractal’s 280mm AIO.

At only 40.9 dBA when running at the default fan curve of ASRock’s b650E Taichi, the noise levels here are relatively low. It’s important to remember that if you prefer fully silent operation, the noise normalized results shown earlier demonstrate that you won’t lose any performance in these power limited scenarios if you set fan speeds to run silently.

Intel i9-13900K Thermal and Acoustic Results

No Power Limits

Source: Tom’s Hardware

We’ll start by first looking at performance with no power limits enforced whatsoever. There are “only” eleven comparison coolers shown here, so I’ve included some of the testing results I have submitted to Tom’s Hardware to give a better idea on how Thermalright’s Frozen Notte compares to other coolers. These results are directly comparable because they were performed using the same system, by the same person (me!).

I’m only including the maximum watts cooled results from Tom’s Hardware in this article. If you’d like to see the rest of the comparison results with the coolers listed below, please check out my reviews there!

The overall cooling capacity results here are quite simply disappointing, cooling 4W less than Iceberg Thermal’s entry level G4 Silent air cooler.

To ensure there was no chance of user error, I tested – and retested – it many times. First in December of 2022, where I tested it and remounted it. I reported the results to Iceberg Thermal at this time, which conceded that this cooler was not optimized for LGA 1700 platforms.

I then put this cooler aside for some time, until after I had setup a Ryzen 7700X system for testing – and then retested it on both Ryzen and Intel platforms. The Intel results, unfortunately, were the same as my initial results in December. To be fully certain, I again remounted and repasted the cooler and the results were essentially the same as December’s previous testing.

200W Thermal & Acoustic Results

Most loads that common users run won’t use more than 200W, so this is a better analogue for a worst case scenario of what folks might actually see in day to day usage. At “only” 63C over ambient the CPU isn’t throttling – but is amongst the worst results I’ve seen in this scenario.

All results shown on Boring Text Reviews are tested in an environment at 23C ambient temperature.

125W Thermal & Acoustic Results

When restricted to 125W, thermal performance really isn’t a concern – though I’ve included that information in the graph below. Really, any cooler should be able to handle this load – even Intel’s stock cooler!

Acoustic performance is much more important in this scenario and in this scenario the X7 Dual performs well, matching my quietest results I’ve recorded in this system while limiting to 125W – however, even with system fans restricted to 35% the system fans of my HAF 700 Berserker case makes 40.9 dBA the noise floor for testing.


Iceberg Thermal’s IceSLEET X7 Dual offers a unique aesthetic with it’s clamshell design and provides great performance with Ryzen’s 7700X, especially when noise normalized for silent operation. I highly recommend the IceSLEET X7 Dual when paired with AMD’s Ryzen 7 7700X.

However, it’s performance is simply disappointing with Intel’s i9-13900K. I do not advise pairing it with a LGA 1700 system.

The IceSleet X7 Dual is currently available for $79.99 USD at Amazon.
