Question Any fan that is put in the case is buzzing.

[sasastanojevic745]

Okay so whichever fan i put in my pc case makes buzzing noise but only when i play games. I tried changing the fan but when i put a complete new one on the same place it still makes buzz noise and its really iritating. What should i do?
EDIT: I tried unscrewing the fan a bit and makes a little less noise.

Change the case… ?

Umm is there a way to do something other?
I have already spent $80 on my pc case.

What case do you have and in which position is the problem fan (top/back/front)? What make of fan are you using?

Try using rubber washers for the fan screws.

I have a "Alexander Weiss C903" pc case.
The fans that i am using right now are stock fans from coolermaster masterliquid ml240l rgb.
Fans are positioned on top, and the buzzing comes from left fan.
edit: the one that is closest to the back fan

Thanks i will try that.

The rubber pads may well help, could be the case has a small depression on it and is too clos to the blades causing the buzz.

You're welcome. They might counter the vibrations that fans send to the case.

I still have the same problem :/ i guess i need to get a new case.

Does the buzzing stop if you temporarily disconnect the back fan?

No, it doesn't.

Okay, I was wondering about possible resonance between the fans.

Overall, I would focus on the fan versus a new case per se.

You mentioned that unscrewing the fan bit reduced the noise.

Use a rolled up sheet of paper or long cardboard tube as a listening tool to pinpoint the sound's location. Put one end to your ear and carefully move the other end around the fan(s). Then follow-up with a close inspection using a bright flashlight and magnifying glass. Look for anything that can vibrate, touch, etc. Cracks, chips, burrs....

Remember that as the fan comes up to speed all sorts of forces come into play and the fan casing, blades, etc. may all twist, stretch, flex, whatever, and something starts touching. Hence the buzz.

Are there any depressions as mentioned by @Schlachtwolf

Cut and fit in masking tape or electrical tape as needed.

Just seems to me that doing some additional experimentation, even if trial and error so to speak, may prove to be worthwhile before going to a new case.

Are you able to take and post a couple of photographs? Someone may spot something amiss or otherwise of interest.

Sounds to me like something on the case itself in that region is loose and when the fan spins up it is either vibrating from the fan, or, the air from the fan is blowing something that is rattling from the air flow. Sometimes cables have paper tags on the ends. Look around inside with a flashlight while your fans are moving and see if you see anything moving slightly. No need to buy a new case to solve a buzz.
