anyone else have issues with the motherboard fan randomly not working properly and makes a horrible grinding noise? it will work normally sometimes, but about 75% to 80% of the time it wont. and its not just noise, the air it normally moves is greatly diminished to the point i worry it would overheat if i ran it like that. had multiple prints ive had to abandon mid print because the fan decided to not work in the middle of it. lost about a spool worth of filament because of this happening.

Open up the motherboard case & check the fan. My had broken screw inserts & was just lying in the case, it fell out when I opened it. I had to use different screws to secure it until Sovol sent me a replacement case.

If you are under warranty Sovol will ship you a new fan. However MANY users have chosen to buy a larger fan in and run it shower. Better cooling AND much much quieter. There are similar mods for the power supply if you search.

The SV06 case is smaller than the ACE. The ACE is roughly 1" longer & 1/4 wider. Maybe something like this: [image] Sovol - MBO cover for bigger fan / SV06 ACE and SV06 PLUS ACE by The Bear |... [image] Sovol SV06 ace cover - increased airflow by lanbov | Download free STL model...

Same here. In most cases it is ok, but sometimes it is extremely loud doing same operations. It looks to be secured well inside the case. I might replace the fan to a larger one running at lower rpm if I will find, current is 4010 24V fan. Maybe anyone of you could give advice for replacement?

When I replaced my case, I did the fan also as it started whining & cleaning didn’t help. 4010 Hydraulic Bearing

sovol was good to me and replaced the fan! i think in the future i will be doing a fan upgrade like some are saying.
