ahh hehe ok i'd definitely have to go with the 200mm fans for overall performance in both airflow and acoustics

as far as the top of the case, it depends on what you are doing with the system. if you are liquid cooling, obviously you'd go with a 240 rad. but if you are air cooling, it depends on where you are putting your system. if you are putting the case in an open area, then intake would be fine after you put some air filter on the top fan. however if you are putting it in a semi enclosed space like under a desk, then you don't want the top fan to be sucking in warm exhaust GPU/CPU/PSU air trapped under the desktop.

You can also use a fan controller for lower noise for regular use/idling and for hardcore gaming/benchmarking just put it on blast biggrin.gif

ill go with 2x120mm on the top and 2x120mm in the front as well. but doesnt really matter though, i just think that 2x120mm is better than 1x200.

pro: alot more choices in aftermarket fans

con: alot more expensive because high quality aftermarket fans are damn expensive.

moving air is alot like moving your apartment, you can make 18 trips in your toyota, or you can make 1 trip in an u-haul.

choice is yours biggrin.gif

120mm fans have an excellent balance of noise and airflow. They run smooth and stable at high speeds because their fin-to-rotor ratio is very well matched, and they have a longer projection of air due to their increased static pressure over bigger fans (making them good for intakes that are a distance from components), and they cause a less wide body of turbulence, making their airflow noise smoother than 140.

140mm is good for exhaust when you can run them at low rpm, due to the increased surface area, but they actually move less cfm per-sound pressure than 120. Not to mention, much more R&D has been put into 120, so there's a large selection of nicely engineered 120's and finding a good 140mm can be frustrating. There are some good ones, like the TY-140, but its 120mm mounting can be problematic in some cases.

120: intake
140+: exhaust
imo.

in the context of computer fans.

however, fan research has begone way before computers were ever invented and much deeper research has gone into aircraft/jet fan blades then computer fans....

the reason 120mm has the most choices atm is not because it has the best blade to rotor ratio, it's because it's the flavor of the year, once 140, 180, and 200mm becomes more popular, 120mm will be just like 80mm and 92mm fans that came before it. 140 and 180mm are more or less transition sizes. IMO the market will eventually settle on 200mm due to current trend and overall case width demands. in another 3 years maybe, you'll start seeing 200mm fans that rival the quality of 120mm fans of today.

but then again, due to die shrinks of the future, the demand for such large fans may not even be an issue. so the market may settle back down to 120mm since there is simply no need for larger fans if ivybridge is only using 70w as opposed to 130w of sandybridge. either way cooling will be lead by the demands of GPU cooling and we may even see the market revert back to focusing on 92mm fans for gpu cooling. who knows, haswell and skylake may only need a 80mm fan to keep cool biggrin.gif

no one has answered what will create better airflow lol

i guess ill just try the 4x 120mm fans at the front intake and top exhaust, then if i don't like it ill move to 200mm's. i already own the fans i just dont wanna do more work then necessary.

The front fans dont bring enough air to cool. The HDD and cage blocks majority to really dont do much.
Remove the top cage completely to allow more airflow through.
A side fan would have more benefit.

For front, I prefer the Coolermaster Megaflow 200mm fans. They do have a nice airflow for the front.
For the top, a 200mm fan will block and use for a ALC cooler, like the Coolit Eco, Corsair H60. Thats when you use 120mm fans for the top.
If a normal heatsink, them a 200mm would be fine.

Which 120mm fan did you actually get?

get some TY-140´s or stay on CM Megaflow
