A must-have for serious gamers

The Asus ROG Phone 6 Pro was recently launched and it is one of the best phones I have ever used. It pretty much threw everything and the sink into a single device, and it launched alongside a range of pretty incredible peripherals. One such peripheral is the Asus AeroActive Cooler 6, which cools the phone via a built-in fan. In the most extreme conditions, with external power, Asus says the phone can be cooled to 25°C, although most users won’t need close to that kind of cooling.

But what’s the point of the AeroActive Cooler 6? For long gaming sessions, the goal is twofold. First, it cools down your phone to prevent thermal throttling, extending your gaming session for as long as you need it. The second reason is that it makes the phone more comfortable to hold for longer periods of time as it doesn’t transfer as much heat to the edges of the phone. It also has buttons on the back that you can bind to touch input in your games if you want to use it, so it’s not only a cooler attachment.

If you have the Asus ROG Phone 6 Pro and are looking for a peripheral for it, the AeroActive Cooler 6 is probably one of the first to go for. Unfortunately, it doesn’t come in the box, despite how essential we’d find it to be for mobile gaming. It keeps the phone cool and prevents it from being smothered while playing your favorite games for extended periods of time, and what’s more, it also pairs well with the Asus Kunai 3 Gamepad. It also comes with its own compatible case in the box, although you can use it with or without that case.

    The Asus AeroActive Cooler 6 is probably the first peripheral you should get if you have the Asus ROG Phone 6 Pro. It keeps your phone cool while adding extra buttons and powers itself through the USB-C port on the side.

About this review: I received the Asus ROG Phone 6 Pro from Asus on June 17, 2022 along with the AeroActive Cooler 6. My colleague, Aamir Siddiqui, also received the device from Asus, along with the cooler. Although the company has provided us with review units, it has not had any input into the content of this review.

Features and cooling options

The Asus AeroActive Cooler 6 has a few features up its sleeve that make it unique. For starters, there are four cooling modes, although the latter can only be accessed when the phone is charging. The reason for this is that each cooling mode consumes more energy, so as you cool your phone, you drain your phone faster. The USB-C port on the side can’t supply enough power to support “frozen” cooling mode, so the phone must be plugged in at the same time. This connection has to be done through the port of the cooler, as the phone won’t let you switch to “frozen” if you plug the cooler into the side port and then charge through the bottom port of the ROG Phone 6.

The cooler also has a small kickstand near the charging port that flips open to allow the phone to stand upright. It’s a bit flimsy – I let it come off a few times and had to snap it back in. Despite all that, the Asus AeroActive Cooler 6’s obvious primary job is to keep the phone cool and avoid thermal throttling, so how do you like it? As it turns out, pretty good from our tests.

Plus, the cooler even has built-in RGB lighting that can be configured through the phone’s Armory Crate app. You can match it with the Asus ROG Phone 6 Pro wallpapers if you want, or just match it to whatever you want.


First of all, this cooler is of course mainly aimed at gamers. Between its aesthetic (in addition to the overall ROG aesthetic) and the trigger buttons on the back that can be mapped to touch input, it’s clear what Asus was looking for here. We tested both in Genshin impact and when emulating The Simpsons: Hit & Run via AetherSX2 and received phenomenal results.

With the cooler turned on, we could play constantly Genshin impact for over half an hour at essentially 60 FPS, something this phone barely struggled with without the cooler. Without the cooler, the measured temperature around the phone was around 37°C towards the sides where your fingers rest, while the SoC reached more towards 45°C.

As regards Hit & Run by Simpson, we tested both with and without the cooler. Without the cooler, the phone reached 43°C after half an hour. This temperature is still fine, but the phone feels warm to the touch and can be uncomfortable for extended periods of time. By mounting the cooler and using it in “icy” mode (the second highest mode, and the highest you can use it when not plugged in), we found that the temperature hovered around 36 degrees at its peak. °C/37°C. Finally, when the phone is plugged in with the bypass charging mode turned on and the cooler in “frozen” mode, the phone will move up and down between 31°C and 35°C.

The Asus AeroActive Cooler 6 gives quite impressive results for intensive gaming sessions.

Whatever happens, these are pretty impressive results for intense gaming sessions. Even if you run it on its second-highest mode, it keeps your phone much cooler than it otherwise would have been without the cooler, protecting the inside of your phone from overheating and allowing the chipset to maintain consistently high clock speeds. .

CPU Throttling Test

CPU Throttling Test is a freely available app on the Google Play Store and it repeats a simple multithreaded test in C for just 15 minutes. We have extended the time to 30 minutes. The app charts the score over time so you can see when the phone starts throttling. The score is measured in GIPS – or billion operations per second. It is essentially a test that can measure the sustained performance of a chipset. While the phone does heat up, it’s not unbearably hot and is perfectly usable even on the hottest it’s reached.

With the AeroActive Cooler plugged in, I also noticed that the Asus ROG Phone 6 Pro did perform better than you would expect. It achieved a maximum of 377 GIPS, while the maximum without the cooler was 341 GIPS. That’s an almost 10% increase in maximum performance, and the average was also similarly higher with the cooler attached. It’s not a necessity, but obviously you’ll definitely get some benefits from using the cooler on your phone.

The AeroActive Cooler 6 is not for everyone

It’s not all good for the Asus AeroActive Cooler 6, though, and there are a few things I’d like to have. For starters, it would make perfect sense both to extend the length of the cooler a little bit, and to vent the air at the top and bottom instead of the sides. The buttons on the back can be harder to reach when playing games, as the ROG Phone 6 is a long phone, and hot air being expelled over your fingers is an uncomfortable experience during longer sessions.

Here again there is the question of position. It’s a thin stand that only allows one viewing angle, and it’s just a little wider than 90° on a table. It’s quite impractical. It might have made more sense to have a stiffer hinge, but on the opposite side of the hinge’s current position at the bottom, and get more movement in that.

Finally, while I understand it’s a Asus peripheral, I would absolutely love it if it was more “universal”. A lot of people could use something like this, but to even make good contact with the phone, it has to be shaped to it. There are some competitors (like the Razer Phone Cooler Chroma or the GameSir X3), but the first is just a cooler and the second is a full-fledged controller. Both also require external power, while this cooler can be powered by your phone. I understand the logistical difficulty in creating a one-size-fits-all solution, but it’s such a good peripheral that I feel like I can be a bit picky and hope it comes to other devices too!

Should you buy the Asus AeroActive Cooler 6?

This is the first peripheral to buy for the Asus ROG Phone 6 Pro

If you have the Asus ROG Phone 6 Pro and are looking for your first gaming-related peripheral to pick up, make sure this is the first. Between the buttons on the back and the extensive cooling capabilities of this fan, it’s hard not to recommend it. It makes games so much more playable over a longer period of time, and you really notice the long-term performance improvement when playing intensive games on your phone.

Asus also plans to launch one of these coolers for the Asus ROG Phone 5 and 5s, so if you have one of those devices and really want a cooler for your phone, you can wait and wait. It will use the pogo pins on the back of the phone, though the company hasn’t said when it plans to launch it.

If you want to cool your ROG Phone 6 on the go for long gaming sessions, you can’t go wrong with the Asus AeroActive Cooler 6. I love it, and it’s been a fantastic addition so I can play games without worrying about getting burned. from my hands or damaging my phone from the heat while making sure to maintain its performance. It’s coming to the US market later, but you’ll be able to buy it soon in Europe for $89.99.
