ASUS ROG Phone 6D Ultimate has a more detailed cooling system

After launching the program ROG Phone 6 Pro gaming phone, it has left some hardcore fans wondering what happened to the “Ultimate” variant. As it turns out, ASUS waited more than two months before revealing “something else”: the ROG Phone 6D Ultimate. It’s identical to the 6 Pro in almost all respects, except for four things: the new “astro gray” color, the interesting choice of the MediaTek Dimensity 9000+ processor (which is what the “D” stands for in “6D”), the switch to LPDDR5X RAM Faster and new ‘AeroActive Portal’ design for blowing cool air into the internal heat dissipation fins – I’ll short this to a heatsink from here on out.

The AeroActive gate itself is a door flap that opens when the assembled AeroActive 6 cooler is attached, so that part of the cool wind generated by the fan – at 1,000 cubic centimeters per second – is directed through a wind tunnel into the heatsink, with hot air exiting the top vent. The heatsink, of course, is connected to the bulky thermal layers that cover the logic board and battery cells, in order to transfer heat from the components to the airflow. This is to help maintain a high frame rate over a longer period while gaming, and also to ensure that the phone is still comfortable to hold.

ASUS claimed that after 60 minutes of testing Perfdog Jinshin effect At 60Hz in air-cooled mode, the ROG Phone 6D reached 36.9°C (98.42°F), which is 3.4°C lower than the ROG Phone 6 in the same mode. This means that AeroActive Portal seems to make a noticeable difference. Similarly in “Frosty” and “Frozen” modes (with the Peltier thermoelectric chip enabled), the AeroActive Cooler 6 is the only Peltier-enabled cooler on the market that does not require additional power externally – it just needs it in order to set “Frozen” the most powerful.

While the AeroActive portal is only launched when AeroActive Cooler 6 is connected, you can open it temporarily in Settings for cleaning purposes. The cover is tightly closed to protect the phone’s IPX4 splash resistance. It also has a fall detection feature to automatically retract the lid, and the stepping motor combined with the zirconium-alloy hinge seems to be good for over 40,000 flips – both building on learning from the now retired camera flip Feature of Zenfone series.

6D Ultimate packs the same set of key features as the 6 Pro: 6.78-inch 165Hz AMOLED display, 720Hz touch sampling rate, up to 512GB of storage, 6000mAh battery, 65W (42min) fast charging, Dirac tuning Front-facing stereo speakers, ultrasonic “AirTiggers” and a customizable “ROG Vision” color display at the rear. It’s also the same set of cameras: a 50MP main camera with a Sony IMX766 sensor, a 13MP wide camera plus a 5MP macro camera; Up front, there is a 12MP selfie camera with Sony IMX663 sensor.

As for the processor, ASUS has surprisingly switched to MediaTek for its Dimensity 9000+ processor, which appears to score a bit higher than the ROG Phone 6’s Qualcomm Snapdragon 8+ Gen 1. The company added that while the Snapdragon main chips have a better GPU, the Dimensity CPU is claimed to be 10 percent more powerful (albeit at the same 3.2GHz maximum clock speed), which is more important for most mobile games. The CPU is complemented by the faster LPDDR5X RAM as well, although that’s the same reason this is specified as 16GB instead of 18GB here.

ROG Phone 6D Ultimate will be available across Europe very soon, with the only model (16GB RAM with 512GB storage) priced at €1,399 (around $1,400) or £1,199. Once again, this premium model comes bundled with the AeroActive Cooler 6. There’s also an ROG Phone 6D launch alongside, which is basically the ROG Phone 6 (so just the RGB logo on the back) but is packed with MediaTek chips and LPDDR5X RAM instead. This starts at €949 (about $950) or £799 with 12GB of RAM plus a 256GB storage base model.

ASUS also launched the ROG Phone 6 Batman Edition, which is basically either the base 6 or 6D (depending on region) with a special storage case, a small LED bat signal display (you can power it with your phone via USB-C), a special Batman Aero case and a slide pin Batman Logo SIM – This comes with its own stand for display purposes. There is no information on US or European availability yet.
