Hello All,
I have had my Flashforge Creator pro for almost a year and love it except for the power supply fan noise.
Is there a power supply such as from a computer that I could upgrade this with to reduce the noise? I am moving soon from an apartment with a garage to an apartment with no garage and might have to keep it in my room for the time being.
I will most likely build a sound deadening box with ventilation to the window for ABS prints, but would like to know if a power supply upgrade is complicated or even possible?
Thanks,
Mason
Is there an upgrade for this such as a computer power supply that I could replace this with to reduc
Generally the Power Supply itself isn’t too loud and it doesn’t run its fan unless it needs to. There is a small 40mm fan that blows air over the main board that is rediculoulsly loud. I removed that fan on both of my printers. The Stepper drivers are running at about 20% of their rated capacity so they don’t get too hot. The other route to keep a little air movement going is find a quieter fan to replace it, or if you can’t find a quieter one try one with a higher voltage rating. Then the fan will at least move slower and should be quieter.
Wow, thank you so much and glad its just the tiny fan. Gonna rep;ace that asap cause that thing is ridiculously loud.
This power supply also works great, it’s fan-less and has the exact specs. I use it on my FFCP. Plus it’s fairly affordable compared to other Meanwell products. http://www.trcelectronics.com/View/Mean-Well/ERP-350-24.shtml
Thanks.
Anyone have any suggestions for upgrade fans? Looking for 24v DC 40mm around 20db
Not sure what the current db is buts its loud
Actively cooling the powersupply is recommended since it is under the machine. Meanwell power supplies are good, but watch for counterfeits. The recommended Meanwell supply is SE-350-24. This isn’t a power supply problem for the noise though. The stock Flashforge supply is just fine. It is the main board fan that is loud. I have been running with it unplugged for several months and all is good.
Thanks again.
Ended up buy one from digikey.

It was expensive but had a db of 22 and should be better then anything off of amazon.
Mouser has a few one that are lower db but a little more expensive or with a huge lead time.
The fan that blows over the motherboard is louder than the power supply fan and it isn’t even necessary. That fan was added in the original Rep 1 specs by MakerBot because they thought it might help prevent the voltage regulator from burning out. It turns out they were over driving the regulator and a simple fix was implemented to drive it off the lower voltage coming out of the other regulator. That fix didn’t make it into the published specs, but FlashForge implemented it anyway. But then nobody went back and removed the fan, so there it spins just making a racket for no reason.
Yes! I had the same annoyance with the fan noises, you need
1-24v 100mm x10mm ball bearing fan
1-12v 100mmx10mm ball bearing fan
The 40 mm fan you hear running all the time is blowing on the stepper drivers its 24v I removed that and placed the 100mm fan on the flat steel undercarriage. Place it centered over the stepper drivers mark/drill the four fan mounting holes and the remove the material below the fan so the air can flow. MAKE SURE it is drawing air from UNDERNETH the matching blowing ONTO the stepper motor drivers/control board .Mine is so quite I have to walk over to it to see if it is running.
The power supply fan only comes on every now and then as it has a temp sensor built into the power supply modification is a bit more tricky… You have to remove it to make the following modification.
Remove the power supply and then remove the aluminum cover, the power supply is fitted with an 60mm fan, again place the 100mm over the existing fan location and mark/drill the mounting holes. Then again remove the material in the aluminum cover so the air can flow. Now the 100mm fan WILL NOT fit inside the power supply and must be attached to the outside (that’s why it’s only 10mm thick) ensure it draws air from INSIDE the power supply blowing down.
If your printer is set in a permanent location as mine is I cut a 3 1/2 hole in the counter exactly below this fan and printed a countertop bushing.
The air is drawn into the machine from the other fan that cools the stepper drivers/control board then the air is sucked through the power supply and discharged out of the bottom into the bushing in the counter and away from the machine.
ive had this setup for over 3000 hrs and it works perfect, I will load pictures as soon as possible.
Hi,
A unique out of the box, well you may call it in the box solution is that you place the unit inside a cabinet and insulate the inner wall of the cabinet with styro or cork. Keeps the heat in plus takes the noise out. Sometimes a non engineering solution can be beneficial too. Hope this helps.
