Tell me if all the water makes it to the other side. If not, you just just experienced restricted flow.... I'll bet money you end up with a significant portion of that water puddled on the ground below the grill. Same thing happens when you try to push air through a grill (minus the puddle part ).

You say you haven't experienced the "problem"....but you haven't cut your grill to experience the difference either. Those of us that have cut our grills can give some first hand experience, and it does make a difference. More air moved out of the case, and less noise....plain and simple.
Aside from the fact that I effectively agreed with you when you revealed that you didn't have a good seal with your fan, you simply cannot have more input into a system than you have output. That's what is plane and simple. And the only way for you to have that significant a drop in your temperatures by cutting off the grill is because you did have a bad mounting job so air was escaping - but again, you never implied you did so I had nothing else off of which to go. Resitrcting flow changes the pressure and velocity of the fluid. It doesn't change the amount.

I've already stated that you needed adequate input (or intake vents)....which my rig has plenty of. And it had as good a seal as you can get with the mounting screws. Back pressure still forces air back through the fan around the blade edges, and can even slow down the speed of your fan blades. You have a limited amount of power turning the blades. Increase the resistance by keeping a grill in front of it and the blades slow down... Drastically? No. Enough to reduce the amount of air being pumped out of the rig? Yep.

You must be still in college taking your first fluid dynamics class.... J/K You act as if the air in a case is a perfectly pressurized pipe or something, flowing in a single direction. There are "local" flow areas all throughout the inside of a case, and "leaks" everywhere. We're not in the class room talking about a simple flow through a single pipe in a single direction. Reducing restriction in a localized area (a few inches from your CPU...you know...where the exhaust fan is) will increase the air pumped out of that zone (with adequate input vents or fans). Especially using a heatsink like mine with an attached fan blowing at it. I doubt you will find one person that will claim that they didn't see a big increase in airflow out of the case in an area where a grill was removed. You keep believing that if you want to, it'll be you that isn't benefiting from the improved temps.

No ****. Go back to that water hose with the adjustable nozzle example... Increase pressure will also cause the fluid to find a less restrictive path if it's available....and inside a case, there are plenty of available paths for the air to go other than small holes through a grill....mainly, right back towards your CPU until if finds another path out.

Actually, I had that removed from my post well before you posted to avoid getting into this further with you, but if you want to play that game then go ahead.

Seriously, grow up! Why you are still dwelling on something I've already conceded given you suggesting you had a poor mount of the fan? And if you agree with my statement about the restricting of flow not changing the amount, then I must ask again why you are still whining.

Sigh... Let's start twisting words, too, huh? I guess not being able to drop something wasn't childish enough, but given the fact that you have now resorted to twisting my words through this post it is clear you wish to act like a child and aren't simply ignorant to this topic.

Yes, I saw that...and edited my post accordingly. My bad for following your lead with the insults.\\

Whining... I can see that any type of discussion with you is probably pointless. When you don't agree, you insult. Nice....

I continued what I considered to be a "discussion" so the OP and anyone else reading this thread would see that cutting your grill can and mostly WILL help reduce temperature and noise in your case.... Call it whining if you want.
