2x 120mm Vs 1x 200mm... Help? - Page 2

post #11 of 16
Do not buy the 200mm Megaflow fans from Coolermaster if you ever decide to stick to 200mm fans. I bought one of these only because of the advertised 100+ CFM but this thing barely moves any air. I've compared the airflow with my stock corsair 200mm fan that has 87 CFM rating and it pushed much less air. I RMAed the fan right away.

The 200 may push quite a bit of air but greatly lacks preasure. I still use a pair on my 932, they do cool at near silent levels but no as much as some 120s with higher preasure.

I think their junk. They don't move any air and they do not cool anything. Plus they won't spin. The RPMs are just terrible slow. These big fans are just not a cooling option.

Well the RPM's be able to be monitored as well?
I wanna use a Scythe Kaze Master Ace fan controller with it!

Cheers,

I'm 99.9% sure that the Kaze Master Ace will show your fan RPM's. I love the Sunbeam Rheosmart, its almost a perfect controller for me, becouse it can split the CPU PWM fan signal to any fan plugged into it! I to am into extreme gaming:) and am outffting my case with some INSANE airflow, will make a HAF case look like a joke:) right now I have 2 of these, I love them. The static pressure is just wicked!! Going to use those on a H70 set up for the wife. I'm also looking into AP-30/31's(they move 100CFM and 150CFM)

When I go and start this up one or more will not start. They move back and forth but will not spin with out some help from me. So I have to spin them around with my finger to get them going ha ha. But I been thinking getting some 140mm fans instead of the 120mm.


Something like these

I like the high RPM and the dual bearings.
If your looking for high RPM there are only a hand full of case fans to look at:P
I use the San Ace 1011's linked above, and love them to death! I've said it befor, I'll say it agin. I HATE non 120mm fans, There is not choice for upgrading, have almost no static pressure. I would make a custom bracket to use 120's in any 200mm case bay. but this is my opinion:)

@KhaoticKomputing I agree.

But I decided to get some 120mm fans to replace these case fans.

Any idea on this Q?

Most companies that sell case fans sell directly to consumers, so they do not need to have very specific stats on airflow and noise.
It is better to get fans from manufacturers who cater to companies that build servers and such. The specs from those are much more accurate, as they are selling to a much pickier clientele. That is why a Scythe Gentle Typhoon costs more, pushes more air, and makes less noise than a fan from Cooler Master, for example.

You can control any fan with a fan controller. All a fan controller does is adjust the voltage going to the fan. Case fans run at 100% at 12 volts. As you turn the fan control down, you are just turning down the voltage running to the fan. Keep in mind that some fans do not undervolt as well as others.
