Corsair Hydro Serires H110i GT 280 Extreme Performance Liquid Cooler

Speaking of fans, coolers, and 750D cases...

I'm a fan of these fans: Noctua.at - sound-optimised premium components "Designed in Austria"!

They are pretty loud at higher RPMs, though not bad considering how much air they move and their extremely high air pressure potential (great for dense radiator/heat sink fins). But, they're decently quiet at lower speeds. I have them set up on custom fan curves on my motherboard based on CPU temps, so they never really get too loud to ever be an issue. They are definitely some powerful fans when you want to crank things up to rip-the-paint-off-the-wall levels for overclock testing and benchmarks though.

Two of these fans are on the top cooler, one in the back, and two in the front.

That's a gorgeous build.

Thanks, though this all reminds me that it's due for a cleaning. (I have it on crunching for BOINC and hosting Minecraft servers nearly 24/7, so as you can imagine it takes a bit of upkeep now and then.)

That is pretty sweet Wrend :)

Looking great Wrend

This ventilation stuff is pretty interesting,
Seems a lot more inlets than outlets
The only outlets seem to be on the back of the case Top back and I suppose the psu is a outlet,
Top/ Front and Bottom are all inlets
Which makes sense they are filtered

Started reading a bit about the fans suggested from LBB and landed here NF-P12 and NF-F12
With a response from Derico a little down the page about manufactures recommended to pull and push...

Yeah. Generally people prefer having higher air pressure inside the case than outside by having more intakes than exhaust and having some air filtration on the intakes to help reduce the amount of dust buildup inside the case. This way you don't get as much dust built up around the nooks and crannies either.

My setup is prioritized more for cooling than for air filtration though, since the fans on my radiator are exhausting the air out the top of my case instead of pulling it in. This way the heat from the CPU is removed from the case and doesn't serve to heat up my GPUs. However, with the air going over the radiator this way, having the fans in this kind of pull configuration, it is easier to keep the radiator itself clean by cleaning off the bottom of it. My setup also works with convection instead of fighting against it and has a fairly consistent and linear path through the case, front and bottom to top and back, to help reduce turbulence and heat buildup inside the case.

I have the bottom vents opened up for intake to help feed the higher exhaust (low) pressure, balancing the pressure out a little more, keeping the case inside a little cooler, and helping to reduce the amount of dust buildup in the nooks and crannies, such as inside my optical drives. I do at least have filters in front of the front fans and on the bottom of the case below the intake vent for the power supply's intake fan (this air is then exhausted out the back of the case after cooling the power supply).

Yea that is one of the issues I see with pulling in air from the top is the top of objects with collect dust regardless of suction = over night or left all day unused so that would be a often cleaned spot,
Of course the bottom is a dust vacuum cleaner too

Then you have fun with the noise levels lol
Cheers.
