A gamer had enough of the extreme heat in his gaming room. His powerful gaming PC turned the room into a sauna. So he designed his own solution to tackle the problem.
In his post on Reddit, a user talks about his heat problem. Between an RTX 5090 and a water cooler, his PC generated so much heat that the room became nearly unbearable despite an air conditioner with a double hose system. An air conditioner with a double hose system is already more efficient because it draws fresh air from outside and vents warm air separately.
To improve the situation, he built a structure out of ventilation hoses, wooden boards, and several fans that were supposed to blow the hot exhaust directly outside. “It felt like a sauna every time I played,” he describes the initial situation and posted pictures of his creation.

From Heatstorm to Cool Silence
This is the structure he built: As seen in the pictures in the Reddit post, the gamer first crafted a cover for his 360mm radiator. Two high-speed fans blow the hot air through a hose directly out of the window. The rear case fan was also repurposed into a second exhaust channel and upgraded with another fan.
To keep the appearance as discreet as possible, he built a custom wooden frame for the window – clearly visible in the photos – so that no improvised plastic solutions were necessary. The hoses from the PC and air conditioner are routed so that both systems efficiently direct heat outside in parallel.
Does the ventilation help? According to the creator, the difference is enormous. The room temperature now remains pleasant, the air conditioner can operate effectively, and the PC temperatures are stable. Measured exhaust temperature: around 110 °F (about 43 °C). “Now it’s really cool in here without the hot PC air circulating,” he writes.
He admits that there is still a slight negative pressure in the room, but it is significantly lower than before with a standard air conditioner. He has also managed the noise level by switching to controllable iLink fans.
How the community reacts: Many users are impressed by the clean implementation. Some share their own experiences with heat-intensive PCs and offer further tips, such as additional insulation or more powerful fans. Others jokingly comment that such “PC heat shafts” should be planned into new houses from the start.
Particularly praised is the “stealth” appearance of the window frame, which is hardly noticeable from the outside. Some Reddit users want to replicate the system to keep gaming cool even in summer.
Anyone who games with high-performance hardware knows the problem: Heat builds up quickly in the room, and cooling becomes a priority. But not only technology suffers from high temperatures; we must also be careful during extreme heat. In the heat, it’s better to reach for tea instead of ice-cold water to cool down.
