Is that VRM fan even remotely necessary though? Even a 3900X or 3950X tops out at 150 or so watts unless you're doing fixed clock OC at unsafe voltages, so 110-130A at most, I would assume a premium VRM with even a middling heatsink and some access to air would be able to cool that just fine.

The fan it's a 6.9mm 30x30mm. I couldn't find any replacement for it. The closer is a DELTA but is 5V, so it didn't work!
That is an odd size. I wonder if Asus uses this for the Z490-I Gaming too. Do you know?

BTW, I did a quick search and 30x30x7 12V fan does not seem to be rare.
Eg this one has 5V and 12V versions, but only 2-pin (ie no PWM)

Then, this one says PWM is available too but min order is 500 units.

I think, if one digs a little deeper, a replacement fan can be found.

Ended up on chinese internet to find all about its bigger sister, the X570-I Gaming.

It Indeed uses 2x ASB0312HP-00 30x30x6.9mm 12v fans to cool the VRM and the chipset. So chances are they reused the same one.



As mentioned, it might a modified version of the Delta ASB0305HP-00 (5V).

By the way, that chinese site as huge technical informations about the X570-I...

Yes! I was only able to find the 5v on digikey, discovering too late that wasn’t working because 5V.
IF the VRM heatsink will be a bit different, you can mount the A4x10 from noctua actually. On the X570 wasn’t fitting for a few mm. But the VRM really doesn’t need a fan though, the temps with the 3950x were around 80C under load without the fan!

Found it in Taobao. There could be more sellers but this is just the one I found anyway.
