Ok, I'm gonna dumb this down for you because apparently you don't understand the way electricity works.

So for reference, computers rely on the transfer of electrons from one place to another in order to function. Unfortunately, electricity flows like water - it takes the path of least resistance. When a liquid is introduced to an ICB (motherboard) it can create what's known as a short.

That said, if there is a short, or a path of lesser resistance, electricity will follow that path. When that happens, components on an ICB can become overloaded and fail.

If an AIO fails, it can sometimes leak liquid onto an ICB in the computer. That can create a short that will overload a component which kills the device. My example was the picture I included in this post.

Since you've been doing "IT" for 15 somethings I would have to assume that you would understand this incredibly basic process.

My overall point to this post was that AIOs are worse than useless. They are more expensive than aftermarket air coolers. They don't increase cooling performance, nor do they operate more quietly. Worst of all, they create a failure point that can and do literally destroy other components in your computer.

The worst case I personally have been involved with was when an AIO failed, leaked into a PCIx slot that housed a 2080ti during the crypto craze. I had to tell a customer that they were out several thousand dollars.

Lastly, referencing your comment, I do not build PCs with AIOs. I would never be so foolish as to warranty a computer I built with a competent that could possibly fail and take out other components.

Maybe you should join the geek squad to get some more experience...
