The Iceberg Thermal IceSLEET G6 Stealth Review: Top-Tier Colossal Tower Cooler
by E. Fylladitakis on October 13, 2022 8:00 AM ESTConclusion
Iceberg Thermal is a newly founded and by all means small company, with only a few CPU coolers and closely related products summing up its entire product lineup. There have been many similar startups that came and went over the past couple of decades, with but a small percentage actually succeeding and staying in business. With the IceSLEET G6 Stealth, Iceberg Thermal is boldly challenging the top players of the PC cooling market, trying to establish a reputation with enthusiasts and other performance users.
The quality of the IceSLEET G6 Stealth is impeccable. No matter how closely one examines the cooler, there is not a single weak point, a bent fin, or a flaw on the plating. The mechanical strength of the cooler is excellent and, in combination with the plating, it ensures that the cooler will be unscathed by the passage of time and multiple installations/removals. It would be extremely difficult to mechanically damage this cooler – only the fan may fail after several years of use but any quality 140 mm fan can easily replace it if that happens.
When it comes to performance, the IceSLEET G6 Stealth does not disappoint either. The company’s marketing efforts are not hollow, as the cooler’s noise figures are exceptionally low. Under normal operating circumstances, the IceSLEET G6 Stealth should be practically inaudible, even with the system under load if it is called to cool a mainstream CPU operating at stock frequency. The design and colossal proportions of the cooler allow for the handling of extreme thermal loads with relatively little airflow, placing the IceSLEET G6 Stealth among the first slots of our performance charts.
The Iceberg Thermal IceSLEET G6 Stealth is a strong contender for one of the best CPU air coolers ever made. Nevertheless, it is not without flaws. The massive size of the cooler necessitates a very roomy case and we're concerned that its hefty weight could easily cause damage to the motherboard if the case is to be transported. Its size also means it will almost certainly cover some of the RAM slots – the clearance of 56 mm will allow for some RAM modules to fit but there still is some compatibility risk with high-performance RAM modules, plus it will prevent the installation/removal of the RAM modules while the cooler itself is installed. Such flaws are not unforeseen for any tower cooler that large and are relatively minor for most system builders, but these are factors that need to be assessed nonetheless. Otherwise, the retail price of $80 is a bit steep but we believe it to be fair considering the quality, performance, and sheer mass of the cooler.
In summary, the IceSLEET G6 Stealth is an excellent top-tier air cooler, designed for top-of-the-line thermal and acoustics performance. For a product from a small company that's still working to make its name in the packed cooling industry, Iceberg's towering cooler makes a very big and very good impression.

That TPC 812 has the vapor chamber on the wrong side of the stack.It should go CPU | CPU heat spreader | vapor chamber | heatpipes. Kind of like how the RTX 4090 heatsink is designed.

Expensive, and more important no AM5 version.https://www.microcenter.com/product/635270/icegian...

Meanwhile, MicroCenter is still the seller and selling it with AM5 support here: https://www.amazon.com/IceGiant-ProSiphon-Desktop-...Foeketijn - Tuesday, November 8, 2022 - link
Then don't delid your CPU. The lid is 100% copper, so that'll take care of any unevenly spread out heat output.edzieba - Thursday, October 13, 2022 - link
Can you add a photo of it mounted on a motherboard to the article? Just the cooler on its own makes it almost impossible to judge scale (as cooler baseplates are not a standard size).Harry_Wild - Thursday, October 13, 2022 - link
Exactly what I want only it too high for my case which has 137mm limit on it! 160 mm is to high!

Too bad it only comes with that color option, especially since it's called the "Stealth". At least it's easily removable to paint and not to difficult of an assembly to model and 3d print a replacement.thestryker - Thursday, October 13, 2022 - link
This seems like an interesting cooler, but like most of the high end air coolers there's so much weight. Would love to see something done bracing wise even if it's just some sort of attachment which can screw into the top of the case.Jonny314159 - Friday, October 14, 2022 - link
These results just tell me to keep buying the NH-D15.NeatOman - Friday, October 14, 2022 - link
I think there should be multiple loads they should be tested at. Heat pipes rely on a small amount of liquid in them evaporate (causing it to cool via phase change) and condense to then be wicked back, these evaporative temps can be change by modifying the liquid. This will in turn give you target temperatures that you have to balance with how well your cooling the heat pipes (fins and fans) and the thermal resistance from the heat pipes to the silicon die.Older chips with much larger die would be able to move much more heat into the IHS and it would benefit to set the gas off temperature higher inside the heat pipes. Now with chips so small it would be harder to move so much heat and a lower temperature would IMO help cool the CPU die better.
The next step is what I've seen on GPU's for a long time. Two stage phase change. First is a vapor chamber block sitting directly on the GPU die and then you have heat pipes on top to further move the heat away. It would be amazing to see the Thicc IHS on the Ryzen 7000 series chips be turned into a vapor chamber.
You can see how the new RTX 4090 can suck down just over 600 watts when overclocked yet with a volume of about equivalent to a max size tower CPU cooler it runs surprisingly cool.
DO IT AMD.. DO IT ! would be amazing if someone made IHS replacements that are said vapor chambers :-)
