Every so often someone looks at a modern flagship phone, sees the raw silicon inside, and decides the glass slab is the wrong shape entirely. That’s exactly what happened when a Redditor took a ZTE Nubia Z70 Ultra and rebuilt it into something that looks disturbingly like a small-form-factor desktop PC.
The trick was cooling. Phone chips throttle hard once they get hot, so this builder went full overkill: the Nubia was sandwiched between two enormous CPU coolers, mounted in a custom acrylic case and fed by a power bank. The result is a phone that no longer behaves like a phone — it can run sustained loads without the usual thermal panic.
And run them it did. The showcase was The Witcher 3 at 1080p on ultra settings, holding 20–30 FPS with the Adreno GPU pinned at 99% utilization. That’s not going to embarrass a gaming laptop, but for a device you could normally slip into a jacket pocket, watching Geralt trudge through Velen at ultra detail is genuinely impressive.
The reason it works comes down to the hardware underneath. The Nubia Z70 Ultra is built around Qualcomm’s Snapdragon 8 Elite, running at a maximum clock speed of 4.32GHz, paired with a hefty 24GB of RAM. In a stock phone that silicon spends most of its life fighting a losing battle against heat inside a sealed chassis. Bolt on desktop-grade coolers and suddenly the chip gets to stretch its legs.
For context, the phone this mod is based on is a very real device that launched globally on November 26, 2024. Its full spec sheet reads like a proper flagship:
- 6.85″ display
- Snapdragon 8 Elite, up to 4.32GHz
- up to 24GB RAM
- up to 1024GB storage
- 6150 mAh battery
Pricing starts at US$789, which puts it firmly in flagship territory — though nobody buying one at retail is expected to strap a pair of tower coolers to it.
What makes this build so much fun is that it’s not a product. There’s no crowdfunding page, no pre-order button, no accessory maker promising to ship you a cooler bracket. It’s a one-off engineering stunt, the kind of thing that exists purely because someone wanted to see how far a phone could be pushed when heat stopped being the limiting factor.
It also quietly makes a point about how much untapped performance sits inside modern smartphones. The Snapdragon 8 Elite is a monster of a chip; most of the time, physics and packaging simply won’t let it show off. Give it a ridiculous cooling solution and a game to chew on, and it happily turns into a pocket-sized desktop replacement — coolers, acrylic and all.
