Need help from people who have cooler master mega low fans

post #1 of 8
Thread Starter 
Hey guys,

I just got my cooler master megaflow fans but I'm not really sure if this fan is indeed 110cfm as it says on the package. I put this fan in place of the corsair 200mm fan in the front and honestly, it's really weak... The corsair fan has lower cfm around 80 and I'm not convinced that this megaflow is pushing decent amount of air in comparison to the stock corsair fans.

I connected the fan to the molex and both the fan controller and in both instances the air push was similar. I also put this fan into the motherboard and looked at the rpm and it said 700rpm which was what was indicated on the box.

I have no comparions that I can make for this megaflow's performance so I need help from other owners. Did I get a bad fan? Or is it just me thinking weird?

It MAY still be pushing that many CFM, but your Corsair stock fan MIGHT have a higher amount of static pressure. So it may be moving what it says for CFM, but not the same static pressure as the stock Corsair.

Hmmmm yeah, I was speculating there might be difference in static pressure. Should I keep the megaflow over the stock corsair 200mm?

Is that the same fan used in the HAF 932?
If it is, the thing barely pushes anything IMO.
but i guess it's just how it's supposed to be (i don't get it but what do i know lol).

Yeah, that's the same fan. I bought it because the stock corsair 200mm fans make a lot of noise and as this megaflow was the only upgrade possible. Yeah, I'm noticing the same lack of air push with this fan unexpectedly..

I can attest to the CM 200mm fans being weak. The 200mm from the top exhaust of my Antec 900 was much more effective at moving air only a slight bit louder but not a big difference.

Looks like a consensus is building on the megaflow not performing as well as expected...disappointing. No decent 200mm fans on the market.

I have Megaflow 200s also in my HAF X system. They really are very weak. It seems as if they are BARELY pushing any air at all. They do run pretty quiet but I just cannot believe that they make ANY difference with regards to temperatures in a system.
