Hello, I want to improve airflow in my case which is Phanteks Enthoo Pro (link). I know there has been a lot of similar topics, but a few thing still is unclear to me, especially regarding fan type (airflow, static pressure). I hope you can help me with it. :)

I'm trying to create positive pressure. I removed lower HDD cage and I installed PSU cover. With this in mind, I come up with the following configuration:

- 2x 140mm front fans (intake)
- upper SP - SP because there is HDD cage behind it
- lower AF
- 1x 140mm AF rear fan (exhaust)
- 1x 200mm SP top fan (exhaust)

I would like to get your feedback.

Additional questions:
1. How about installing 200mm top fan as intake? There is dust filter at the top.
2. There is a possibility of putting one additional 120mm fan as intake on the HDD cage or at the bottom (directly under HDD cage), but I'm not sure if there will be any difference.

Thanks in advance for your help.

The air filters on the enthoo pro are a bit restrictive, especially if using the top as exhaust fans. I pulled the top off mine, carefully bent the metal tabs straight that hold the grill on and removed the fine mesh screen. For the front intake you may want to use both sp fans. Even though the hdd cage will be removed from the bottom the filter is again a bit restrictive. Obviously you want that filter left on for intake.

Depending how your gpu is oriented, have you considered using the lower cage and removing the middle hdd cage? That's how I have mine so there's a clear path of air to the gpu and rest of the system. The lower cage doesn't block much except the front of the power supply and the power supply will be getting the most...

I can't comment on the 200mm fan as a top fan, I didn't have much luck with the stock 140mm phanteks fan horizontal (like a top exhaust). There was extremely bad vibration. It runs really smooth as a rear exhaust though. Quality 140mm fans work well as top exhaust, I imagine even one would work well near the rear over the cpu and vrm.

Unless your hdd runs really hot, I don't think a bottom fan would help much there. Hdd's shouldn't run overly hot and a bottom fan will mostly be blocked by the first drive it hits anyway if you're using multiple drives. (Multiple drives more likely to cause heat build up from storage devices). Hope this helps.
 
Solution
I have the same great case Phanteks Enthoo Pro.
The case comes with a 200mm in the front for intake an a 140mm in the back for exhaust.
Fan Compatibility page 13 on the manual
Top-3x120mm,3x140mm,or 1x200 fan's
Front-2x120mm,2x140mm,1x200mm fan's
Bottom-2x120mm,or 1x140mm fan's
Rear-1x120mm, or1x140mm
These are just where the sizes will fit in the case, but it doesn't say witch is the best air flow for the intake and exhaust . I guest the rear and bottom fans would be for exhaust IMO my power supply fan is facing down to exhaust the air. You can take the hard drive cage out if you don't need it to get better flow.
 
Thanks for answers!


It seems that your configuration with lower cage might be better. I've just checked position of gpu and it is true that upper fan would have clear path to it.

I don't know that much about air and its flow, but lets consider scenario I provided before with both bottom case and upper hdd cage fans. You still have fan blowing right into gpu (from cage) and additional 'power' coming from combined bottom and lower front fan. Wouldn't this setup be superior?
