Sovol SV06/SV06 Plus Ultimate Motherboard Fan Mod 92mm

This is a nice build. I went with the type B cover, but did things a little differently. First off, instead of removing the stock fan I flipped it so it would pull air out while having the 92mm fan push. Second, since my power supply is not in my enclosure I decided to just wire in a DC stepdown buck converter outside the case and run it back to the fan. The more I think about it, I might turn them both around so they don't blow air onto the build plate. It hasn't caused any issues yet though.

BTW, if you want to avoid the whole fan coupled with the part cooling fan just wire them in to pin 1 and 2 on the screw in terminal. It is also silk-screened on the board. (edited)

One big drawback of this type A model is that if you are using the nautilus fan, it would crash with the 92 mm fan.
I have created this model to shift the motherboard to the left, thus avoiding the collision.

I had problems with overheating stepper drivers and print would fail midway while printing ABS inside an enclosure.
Did this mod. Hopefully the issue would not occur.
I drilled a hole and added a separate 12v power cable to power the fan.
I added a grill since I did not find the fan cover mesh in the listed files.
Only drawback is that I need to be conscious while printing since I will not be able to utilise full printable area.

Hey. I am considering this mod, but i have some small concerns:
- Using type A, what is the impact of fan draft on the print area? Even if the 92mm fan is spinning slow, i can see it moving enough air to unevenly cool the part being printed, maybe even the bed
- As for type B, it seems to rely on air being pulled through, but the heat generating components and heatsinks are all on the other side of the board, so it goes from active cooling from a small fan to a big fan pulling heat out of a plastic box full of holes

Am i overthinking? Whats your experience?

Instructions and installation were a breeze, minus the fact that I used m4 screws for the fan that interfered with the bracket used to mount the mobo on the gantry. I switched to the fan screws that came with the fan. Chock it up to user error.

Hi,

Just downloaded and printed this (thank you!)

Got the Arctic fan you mention, have you got any advice on wiring this in? I’ve opened it up and seems to be the writing between the two don’t match at all, so any advice on the tweak needed here will be a huge help!

Am I correct in that with this upgrade the new fan will get its power from the PSU directly via the buck converter, instead of the MCU where the old one is plugged in?
