Question Direct air cooling

[demoncheg]

I tried blowing on the processor with a cooler with the radiator removed, but it quickly overheated. I think the dense air flow of the big cooler should be directed into a narrow hole, blowing over the exposed chip. There are no such fans on sale.

Probably because the cost of making a large bladed fan with a tiny motor would be more than unfeasible. To add, you're trying to make salad in a bowl without the ingredients, namely in your predicament, the heatsink. In case that didn't register, you're trying to reinvent the wheel. To that, please don't.

If that still didn't make sense, try and go back to the drawing board, learn a thing or two about surface area, thermodynamics and convection cooling.

On a side note, this thread will meet the same fate as your prior thread here;

Discussion - Direct air and flow liquid cooling

If you put a fan inside the bearing, you can cool the processor with a direct stream of air. A sealed waterblock will allow the chip to be cooled by a stream of water.

maybe you are doing it wrong. design your own processor that don't need cooling

processor that don't need cooling

But the colder the processor, the more powerful it is. Modern cooling is minimal.

Ask your self this, if your design was so obviously good, don't you think it would have been adopted by now? Just air being blown directly onto a CPU is not going to have enough cooling effect and still be able to be housed in a typical PC case.

In addition, the CPU's IHS doesn't have enough surface area to just rely upon air to cool it. Heatsinks help distribute the heat and provide additional cooling area.

Do they not teach logic in schools anymore?

A reasonable person would figure that if you reduced the surface area by 100x, then you would probably need somewhere like around 100x more airflow to make up for it. That amount of airflow concentrated into a small spot would probably be impractical to achieve using a fan, but pretty easy with a large air compressor, though noisy and with high energy consumption.

Thinking that you could just remove 99% of something and it would still work is magical thinking, as it's unreasonable to assume things are routinely made 100x better than they need to be.

No matter how fast you could blow the air, it wouldn't be nearly as fast in dissipating heat as conduction through an appropriate metal.

But the colder the processor, the more powerful it is.

If you get your CPU down to -250°C with Liquid Helium, it'll certainly run faster (9GHz).

Perhaps you need a really big radial fan generating huge volumes of air. Try this 1.5kW fan with a custom made nozzle aimed into the "narrow hole". Make sure your computer is strapped down.

Basic concept exists, and doesn't make sense for a personal computer:

You will need the radiator to quickly absorb the high focused heat load, unless you can think of another material to soak the heat and then use your fan method, maybe experiment and let us know how it goes

 

[rgd1101]

I think the OP make believe the little fan he have can push out off the heat.

Yea I think so, I am kind of hoping he pulls a mad scientist and finds some new way to cool a cpu by accident.😎
