The Q300L from cooler Master is noisy isnt it? the fans area dead quite, but because the air needs to get through small perforated holes there is quite some air turbulence. has anyone else experience this? and has any one have any luck with a solution. I'm going to try and just cutting the steel around the intake fans.

Reduce the fan RPM? That's a much simpler solution...

I tried it took the fans to just around 20% speed, and I get weak air flow, I'm air cooled BTW. I noticed it after moving my fans from my old case and started getting these awful noises that never happened before unless I was using 100% speed.

What does air cooling have to do with anything? Look at your temperatures. I also use air cooling, and all my case fans run at <500RPM, with no measurable temperature issues.

So? The temperatures don't necessarily matter at all.

Yes everyone will have this issue with the cooler master Q300L and the newer Q500L. Those holes are are terrible for airflow and an awful design choice as a whole. The same fan will blow more air and make less noise in a proper fan mount with honeycomb cutouts. If this entire case was honeycombed instead of holes it would be a pretty awesome case. They would probably need to use thicker steel but still....

 

I'd just sell it but if you're set on keeping this case you might need to go with the old school hole saw + wire grill solution. Just make sure that's where you want the fan mounted if you do this.

Those fears were the reason I went with the Thermaltake Versa H18 TG for Blue Build 2018 over the Q300L. 

 

My suggestion would not be to cut the whole thing in a 120mm hole per fan, but rather leave an x or a cross (or reinforce the 120mm hole later with a thick grill) since the material is so thin, removing a good 30% of it will significantly weaken the front panel.

Gamersnexus just reviewed the bigger Q500L if you want real data showing how awful those holes are for airflow.

ok so I just finished cutting it open, and it is awsome, and frankly it isn't even seakend in any way, and I've given it pretty big holes. Now the case is silent and cool, I got around 6 degrees C of now on the same noise level. and I have no issue with it reving up now, it is still quiet enough not to bother me anymore.

I have the Q300L and the case fan is LOUD.

Post pics of the case you cut open! What tools did you use?
