[SOLVED] Why my 2 front PC fans act like it exhaust air, but actually I configured it as intake fans?

NEED HELP!

Hi, I still confuse till this day why my 2 front PC case fans act like an exhaust fans, but I actually set it as intake fans. My other intake fans work just fine, but this 2 front fans act weird, I 100% sure and have make sure those 2 fans set as intake fans. I still feel a bit air coming into case through that front fans, but when I tested it with thin paper, tissue, even plastic, those 2 fans sucked the objects that I put in front of it. I have no idea why it's happening.

My PC Case: Darkflash DLM22 (doesn't have mesh holes or ventilation in front case, only has mesh holes besides the case, the other side is tempered glass.

My PC fans configuration right now:
1 rear intake fan
2 top exhaust fans
2 front intake fans

Things I've done:

1. Switch the fan with other fan brand (didn't work) (which means it's not about the fan, maybe about the PC ventilation or something)
2. Tried to set new fans configuration, hoping the airflow will get better (didn't work)
3. Open the tempered glass (didn't work)

Your suggestions will be helpful

it's not blocked, actually besides the front fan holder, i just didn't capture it in the photo, there are holes to receive the air that was taken from outside of the case. it is not totally blocked it

What if you put a tissue in front of your case and it sucks in the tissue then its properly set to intake fans. If the tissue blow up in the air then its set to exhaust fans. Don't make this more complicated then it should be, very simple. 😆👶🏽☮🙈

Chalk it up to bad chassis design.
The Bitfenix Enzo does something similar if fans are installed in the front.

I believe the case needs to be completely closed for the front fans to work properly. Both side panels need to be in place.

That is also a possibility.

So...
Tape the tissue on the fan, inside the case.
Close it up.
Power up.
What does the tissue do?

I doubt there's any scenario in which the front actually works well.

From the pictures and reviews I found for your case it has terrible air flow from the front fans.
Not recommended for high performance parts.
The little slots down the side provide half of their air and the slots inside provide the other half of their air.
Which means little air flow and about half of it is recirculated hot air.
Looks good but has terrible cooling.
