What does the fan on this AIO cooler do?

It says in the product description in the newegg link:
An additional 40 mm fan next to pump helps cool the motherboard's VRM chips. This prevents overheating, especially when overclocking, and allows continuous heavy loads.

Wow, that's one gimmick I'd actually be interested in.
If it doesn't add to the price, and the reliability of the pump itself is the same, I'll probably get that one for my next build.

Think of it this way: With normal air cooling, there's at least some side draft that occurs that will blow a small amount of air across the nearby motherboard components.
But with watercooling, the air is stagnant everywhere except the radiator. Well, now it's not stagnant anymore.

However, if that tiny fan makes ANY noise, I'd probably laugh and keep walking. So I'll read more reviews on it first to see if it's as interesting as it appears.

The Arctic Cooling AIOs tend to be some of the cheapest especially when you consider how well they cool for the money. Also the little fan can be unplugged if memory serves.

I would expect a small surge in their quality, as I recently saw some benchmarks that compare one of Arctic's fans very competitively against Noctua.

I doubt they'd want to miss their chance to shine if the spotlight is on them.

This thread reminds me that I was going to pick one of these up. If it's good enough for Steve of Gamer's Nexus, it's good enough for me.

They aren't easy to come by currently at MSRP. Couple 3rd party scalpers on Amazon have them.

Ooops. :censored: Shame on me for not reading the full product description. :wideyed:

As the OP, I found this thread lvery, very helpful. I was going to get that high-end Noctua air cooler, but now I'm leaning to to Arctic Cooler II 360.

I’d rather just put a fan bracket over top of the socket area and run a large, quiet fan. But again, mostly not necessary if you have good case airflow.

Speaking of that, I've wanted to get one of these:

Just mount it to a top or rear case fan (you can double it up on a regular fan) and aim it at the VRM/chipset/SSD/whatever...

But man, they're expensive.

EDIT: Just looked, seems you can't even buy this thing anymore.
I guess $80 for one fan was asking a little too much... not enough RGB?

Could probably make something similar to just mount standard fan to. Maybe 3d print it or something.

True, but my desire was more out of curiosity than anything, I don't really have a personal benefit. Maybe if I get a board with a really horrible VRM or heatsink.
Time to build one yourself? https://www.amazon.com/Soldering-Flexible-Alligator-Electronics-Assembly/

Check out that sort of thing.

The glorious infinity of technology awaits you. It's time to stop being a consumer- Enter the world of supreme engineering.
Link is broken, but I know what it is. I like the articulating arm idea though, maybe with a GPU fan attached so you wouldn't have to deal with a big clunky frame.

I have this Cryorig AIO with a fan:

https://www.newegg.com/p/2SA-0005-00003?Item=9SIA4UF3GA3246

It does seem to work, and I was able to get to 5.0GHz with it.

Only problem is that the fan and pump can become annoyingly loud to the point where I wonder if something is going to break.

If I run everything on stock or with a light overclock, it is fine, I have it back on stock now so I don't overwork the machine.

it's a gimmick but it does work though.. at least it's not a gimmick used to justify a higher price.. cough rgb cough..
Haha I agree rgb is gimmicky as hell. However, I knowing this, still purchased the piss out of it haha I love RGB but just wished it wasnt such a premo price.

A real 60mm fan or other tiny fan placed where your actual vrms is better than this and that would only cost ya 5 bucks. And then you can control its speed and not be annoyed by the noise.

Meh gimmicky af

If your board cant cool the VR mosfets without added 3rd party cooling you have a shit board.

lol...

Gimmick that actually does something potentially useful on a product that costs less:
"How Lame"

Gimmick that adds nothing to functionality on a product that costs more:
"OOOOOOoooo Gimme THAT one!"

If you saw the review I posted above, or any other review of this thing, you'll see it doesn't create any noise, very low RPM. But yeah, you could pay more money for a fan you likely don't need anyway.
Also you would see in any respectable review that the VRM fan is not the main reason to buy the cooler.
The main reason to buy it is CPU cooling performance that beats Asetek designs while being $20-$40 cheaper.

The problem is that virtually all motherboard VRM heat sinks are designed with air cooling in mind. They are designed to be cooled with the air that comes off a typical CPU air cooler. Water coolers, including AIO's don't provide this airflow and as a result, motherboard cooling is less than ideal. Even if your fancy X570 or whatever motherboard can handle not having any active air flow over it's VRM heat sinks, this still isn't how they were designed, nor will it produce the best results.
