iQOO Neo12 has a cooling fan, a 9,000mAh battery and a 185Hz screen

The iQOO Neo12 will have a cooling fan inside it. iQOO confirmed it on 9th October 2026. The phone launches in China later this month.

iQOO is vivo’s gaming brand. The Neo phones are its cheaper line, sold below the numbered flagships such as the iQOO 16. iQOO now says that from the Neo12, the Neo line becomes a second flagship range next to them. No Neo phone has had a fan before. iQOO first put one in a phone in February, in the iQOO 15 Ultra, its top-end gaming model.

Luo Jiahui, iQOO’s Neo product manager, said in a video on 9th October that the Neo12 is coming this month with a new version of iQOO’s Ice Dome fan and a redesigned air path. A day later, in a longer post, she called it iQOO’s biggest fan yet.

So the questions are what a fan does inside a phone, what the catch is, and whether you can get one here.

Why a phone needs a fan

Your phone’s chip gets hot when it works hard, and games make it work hardest. Most phones have no moving parts to deal with that. Inside them is a vapour chamber, a thin sealed metal plate with a little liquid in it. The liquid turns to vapour over the hot chip, then condenses at the cooler edges, so the heat spreads out across the phone. The frame and the back then pass that heat to the air around them.

That works for a while. But after half an hour of a heavy game, the whole phone is warm and there’s nowhere left for the heat to go. So the software slows the chip down to protect it. That’s called thermal throttling. It’s why a game that ran smoothly for the first ten minutes starts to stutter, and why the phone feels hot in your hands.

A fan changes that by moving air. It pulls cooler air in through a small opening, blows it across the hot parts and pushes the warm air out of a vent. Because the heat leaves the phone, the chip doesn’t have to slow down as soon. That’s what Luo pitched in her post: hours of play at the highest settings without the frame rate falling or the phone getting hot.

So if you play heavy games for long sessions, the fan is the part that decides whether the game is still smooth an hour in. For calls, chats and social media, your chip rarely gets hot enough for it to matter.

What iQOO has confirmed

iQOO’s official poster from 10th October lists four things.

1. The first is the fan, which iQOO calls Ice Dome air cooling.
2. The battery is 9,000mAh (iQOO’s typical figure) in a single cell, made with silicon-anode technology, a battery chemistry that packs more charge into the same space.
3. The screen is 2K at 185Hz.
4. Then there’s a pair of chips: Qualcomm’s Snapdragon 8 Elite Gen 5 and Q3, iQOO’s own gaming chip, which handles extra graphics work such as adding frames so motion looks smoother.

The Snapdragon 8 Elite Gen 5 is last year’s flagship chip. The iQOO 16 and the OnePlus 16 both moved to the newer Snapdragon 8 Elite Extreme Gen 6, which we explained last month. That makes the Neo12 a close match for the iQOO 15 Ultra from February, which has the same two chips and a fan. The Neo12 adds a bigger battery and a faster screen.

The screen comes from Visionox, a Chinese display maker, and uses a light-emitting material it developed with Tsinghua University. They say it uses more than 12% less power and lasts 15% longer. iQOO, Visionox and Tsinghua will explain the screen at an event on 14th October at 7pm China time, which is 2pm in Nairobi. vivo’s online store in China is already taking sign-ups for the phone.

What the iQOO 15 Ultra’s fan tells us

iQOO has published nothing about how the Neo12’s fan handles water, dust or noise. The iQOO 15 Ultra, the phone it’s closest to, gives an idea of how iQOO did it last time.

On the iQOO 15 Ultra, the fan is 17mm by 17mm with 59 blades. Air comes in through a hidden intake behind two dust screens. iQOO rates the fan and its air path IPX8 and IPX9, the same ratings for water as the rest of the phone, which means it survived 30 minutes under 1.5 metres of water and a high-pressure hot-water spray in iQOO’s tests. The fan has three automatic speeds and a manual mode, and iQOO puts its quietest setting at 20dB, quieter than a whisper. The phone comes with a dust brush, and vivo cleans the fan for free at its service centres in China, up to 12 times a year for vivo members.

Those details tell you the catch with any fan phone: there’s an opening, so dust can collect and the fan can be heard. iQOO hasn’t said the Neo12 gets the same dust screens, water rating or free cleaning.
