Removing Grill from Exhaust Fan

SIMP · 04-15-2008, 04:41 PM

All,
How much difference will it make to cut out the perforated grill at the back exhaust fan? Seems to me that that grill limits the amount of air that fan can pull out of the case? I own a Centurion 534 as shown below.

I did it to my case, and I used tin snips.

I say more air is coming through, and its slightly quieter, but that is based on the un-scientific ear test.

i can assure you that it is not the grill that limits airflow, there is no way a case fan is pushing things to the max. all you are going to do is get your fingers caught in the fan. i really dont think it would help you

Wrong.

Removing stock fan grills is always a good idea.

*taking notes here* I was asking myself this very question this morning, as to whether or not it's a good idea.

Removing the grill makes a pretty noticeable difference in air flow, and a slight difference in sound levels. I would recommend putting on a fan grill afterwards though, so you don't get your hand caught up in it.

OP's picture actually looks pretty open. It looks sort of like the honey comb design on Antec cases.

On my CoolerMaster case, it had tiny little holes. It was more closed than open.

I doubt it limits too much airflow...however I may be wrong.

The only thing I've ever seen that needs to be removed/cut to get better airflow is the plastic on top of the TT Armor Case. It has extremely small holes, and almost no air gets out. Bad Design.

2 1/4” works good on the 80 mm and the 92 mm. I would not use these sizes of bits where they will show but on the back and under the front cover it works good. Yes a cheap wire fan guard is a must.

IMO it will cut the fan noise by 1/3 or more and you can feel the difference in air flow. 2 1/4" is 83 MM if I’m thinking right.

I was thinking this myself actually...

Would it be worth doing it to the Antec 900, and what tools can you use?
