Observation - LED Biocube 32 Fan

I just purchased a Silenx Fan for mine.. Should be here Monday or Tuesday. Planning on making an adapter for the 50mm to 60mm. Here is the specs.

Rated dBa: 12
Dimensions 60x60x25mm
RPM:1700
CFM: 14
Bearings: 2nd gen fluid dynamic bearings.

They make 3 different 60mms
a 8 dBa pushing 10 CFM
a 12 dBa pushing 14 CFM
a 16 dBA pushing 18 CFM

This is what I used also, fan is very quiet now. I even used the rubber isolators that came with the fan. These fans are like 10 bucks, I don't get why they just didn't put a better fan on to begin with.
 
Smoke, i found the exact same design. I was going to have a friend make one.. After seeing what Scurvy posted, I'm glad I just went and purchased some lexan instead. I have yet to tear down the lid. Scurvy is there room to put a 2nd fan in there or would it even need it?

I'm going to do the same...get some lexan.
i plan on putting in high end leds for sps after the 1st so ill probably do two fans if they fit

There's plenty of room for another fan. Not sure how you would mount a second fan though since there is only mounting posts for a single fan other than poking some holes in the top of the hood. Also, it is only set up for wiring one fan. I suppose if you know a little about electronics you could figure out how to wire a second fan.

I can't really feel a whole lot of heat coming from the vents when the lights are on so I suspect a second fan wouldn't do much.

I'm going to hold off on the 2nd fan for now. I was thinking I could make another adapter out of lexan and epoxy it to the underside of the lid if I ever did need one..
 
I received my hood replacement today. It's much quieter. My original hood was at least thrice as loud. The new hood is still a bit louder than I would expect (inside the specs of a properly operating fan), but it's a entirely constant sound. No more intermittent soft grinding sound.
 
So they just gave you a new hood and you didn't have to send your other one back?
On a side note, I installed my new fan yesterday.. can't even hear it. Took it back apart to make sure it was even working.. lol
 
Curious. How do you mounted a taller fan? Are the stock screws extra long so it can accommodate a centimeter taller fan?

I misunderstood your question with my other post, but it still applies that you probably have to cut the mounting posts down.

But to answer your question, the thicker fans do not have a solid housing. The screw does not need to be as thick as the fan, in fact, you will probably need a shorter screw.

The fan I bought has these rubber anti-vibration plugs that I used instead of screws on 3 of the holes. I will try to explain what I did. I didn't have to cut down my mounting posts at all with a 60mmx25mm fan..

1.) I used a piece of lexan about 3.5" x 3/5". I set the lexan in the very far corner where the center tab/lip is located and the back of the hood.
2.) I aligned one mounting hole in the hood with 1 mounting hole in the new fan. This if course will only work for one of the holes.
3.) I then marked the mounting post across from that point on the lexan.
4.) I then drew a 60mm circle based on mounting the new fan with the shared hole with the hood.
5.) You will then notice that the mark for the mounting post across from where the fan/lexan/mounting post will be attached is inside that circle.
6.) I drew a tab around that mark so I did not cut it out when cutting the circle out in the lexan.
7.) Cut the circle out without cutting where the 2nd mounting point to the hood would be.
8.) I then test fit the fan/lexan to the hood and marked the other 3 holes that need drilled to mount the lexan to the new 60mm fan.
9.) I then pushed the 3 rubber plugs through the lexan.
10.)I then mounted the lexan to the hood using a smaller screw. This is the hole that has the tab I didn't cut out when doing the circle.
11.) I pushed the plastic plugs through the fan and locked them in.
12.) Lastly I installed a screw in the hole that lines up the fan/lexan/ and the mounting tab in the hood.

I only used the .093 thick lexan and when I was done, the fan was no higher than that divider that is built into the hood.
 
^^^ great reply. Thank you.

What would be a low decibel rating for a 50-60mm fan?

The fan I bought was rated at about 10 decibels compared to close to 30 for the stock fan. You literally cannot hear my fan unless you put your ear to the vents. The key is to find a fan with similar CFM at a lower RPM.
 
Stock is about 36ish. Below 20 would be optimal.. I would just make sure the flow is 12 or more..

Thanks. I'll keep looking I came across a few but they fall in about 25Dba so I'll keep looking.
