Fans in Dark Base 900 Pro Rev.2

Recommended Posts

Posted · Original PosterOP

Ok, so I am wondering a couple things.
1. Is it possible to have 3 fans (either 120mm or 140mm) in the front, while having an optical drive?
2. If you have an optical drive, then can you still have up to 3 140mm or 4 120mm fans on the top? 
3. Is there enough space on top to have 3 120mm fans and 1 140mm fan?

4. How do fans fit on the bottom? The manual diagram says 1 120mm fan, but later states it can fit 2 140mm/120mm.

you can have 3x140 without the optical drive.

Only the fans, nothing else.

Ok, do you know if you can also have the optical drive if you were to do 3x120mm (I know it ships with 2 140mm)?
How about if you have the 2x140mm it comes with, and then an extra 120mm?
So basically, if the fans are 360mm or 400mm do you know if you can still install an optical drive?

No optical drive with 3 fans!

I know this thread is a little old, but I seen it and thought I could help since I just built a new PC using this case.

Yes, you can still have 3x140mm or 4x120mm fans on top even with the optical drive installed. I don't have an optical drive, but I mounted my 3 top fans on the topside of the case's sheet-metal, under the top case cover. This put them completely out of the way of mobo cables and an optical drive (if I had one installed).

Looking at mine with 3x140mm top fans and doing some measuring, I don't think you'd be able to fit that combination of fans. I think it would be close and they might physically fit, but I don't think the mounting holes of at least 1 fan would line up with the provided mounting points so you'd have to figure out how to secure it. Also, mounting one slightly past the provided mounts towards front of case may cause issues with the wiring from the front I/O panel and wireless charger. Towards the back you have to underside of the top cover that you'll hit. I think 480mm total is all you can fit, not seeing where you can sneak in the extra 20mm trying to fit 500mm total on top.

You might be able to fit two if you have a super short length power supply and even then I don't see it working (mine didn't). The PSU will most likely partially cover one fan mount. I will include a screenshot right from their manual.... pages 90-91 to be exact. You can see the PSU partially covering one of the fan mounts. Their procedure is not mounting the PSU right at back of case. Instead, they have a panel at back with their own switch and power cable pass-thru. You plug their cable into your PSU and the power cable that came with your PSU into their panel at rear of case. I believe they did this because the internal layout of this case can be inverted if desired. Unfortunately, this doesn't let the PSU sit back as far as it normally would, even if you choose the rearmost mounting position for it. If your PSU somehow cleared the rearmost fan, all of the power cables coming out of it would sit right above the fan and may even come into contact with the fan blades if they drooped any. My PSU wasn't even close to giving enough room for a second fan.409331425_casehelp.jpg.0376ac923d46e787a6057b101c26f3ab.jpg
