At this time of year we all know that RTX4090 It’s the most powerful graphics card around, and even though its cost is out of reach for most users, it remains manufacturers’ favorite toy for trying new things. This is the case of ACERwho presented an RTX 4090 with special cooling that integrates a liquid refrigeration (radiator included), and which turned out to be worse than any graphics card with a standard heatsink by plane. Is anyone surprised?
It is not that ACER is a manufacturer known precisely for the innovation or the quality of its products, and it is that if you go out of the range Predator in fact, the manufacturer is best known for its low-quality OEM PCs. However, this RTX 4090 does indeed belong to the Predator family, and despite that… well, they wanted to innovate and let’s just say it backfired.
The ACER RTX 4090 with integrated radiator, who invented it?
This is not the first time that we have seen a graphics card incorporating a liquid cooling system to keep the temperature of the GPU at bay, especially in high-end models as is the case. But the novelty in the design of this ACER graphics card is that they wanted to create a GPU with an integrated AIO liquid cooling system, so that it does not have a separate radiator that we have to install in the PC case, but rather in the graph itself.
And of course, what is obvious to everyone does not seem to ACER engineers: instead of removing the radiator from the graphics assembly to keep the heat away as much as possible, they think of nothing other than integrate the radiator between the fans. and the PCB, so the fans push the hot air precisely TOWARDS the PCB, making it hotter and hotter. And I say that the rest of the manufacturers who launched graphics cards with liquid cooling did so with a separate radiator, maybe there was a reason, right?
The fact is that the guys from KitGuru have already had the opportunity to analyze this RTX 4090 from ACER, and they realized that this “innovative” design is only useful for making graphics. It’s hotter than if it had a standard air heatsink, which would also force the graphics card to reduce its performance (Thermal Throttling) to preserve its integrity, which would eventually lead us to be faced with the worst RTX 4090 on the market.
In fact, if you look at the graphs above, the temperature reached by the GDDR6X memory in the graph is more than worrying, reaching 96ºC, a temperature that exceeds the recommended maximum of 90ºC and which is therefore dangerous and could damage the integrity of the graphics. As we said, for us it is obvious that if you have hot air from the radiator coming out towards the PCB it will only serve to heat it more… but for ACER it is clear that this was not not so obvious (or that they didn’t bother to do testing with prototypes before releasing the graphic to the market).
