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

post #1 of 16
Thread Starter 
Hey All,

Im looking to get the HAF 912 Advanced, and im not sure if im sold on the big 200mm fan at the front of the case, it says you are able to change it out for 2x 120mm, so im wondering which would provide better airflow?

The 120mm fans i was considering are Coolermaster Xtraflow, or the Xigmatek
On a side note, is the Xigmatek's Fan speed adjustable with the aid of a fan controller?

Againts the stock 200mm fan which outputs 110CFM

All advice and opinions would be greatly appreciated!

Cheers,

Ishi

You will sacrifice noise for airflow. A 200mm fan can move a lot of air at low dBa.
Also, I would take the specs on the fans you linked with a grain of salt.

To OP: I agree with spaceballs, do not trust the specifications listed on the site. Look for a review for it's true specifications.

The specifications give an estimate and are usually wrong.

Yes, they can be controlled.

My opinion, I cant stand it when a case puts bigger than 120mm fan mounts. There are what like 3 fans you can use? no options what so ever.I would swap out the 200mm fans for 120's if you can. Why? becouse you have options! you want high flow? there are 120's that make 200's look like a joke! Silent operation is your thing? NP, just get some TY-140's, They have 120mm mounting holes(but are odd sized), if the TY-140's dont work out, there are always Scythe GT fans:)

I was having a hard time choosing between the HAF case's and CM690IIAD. I went with the 690II and am so happy I did!

Also, Any fan will work with a fan controller. The fan controller limits the amount of juice the fan has to work with, thus lowering the RPM of said fan. ALL FANS work that way(at least the fans we use). However some fans might make some odd grinding noise, or click when undervolted.

Thanks for the reply, im just getting back into gaming, and computer, after about a 3year sabbatical... Not only am i getting back into it, im getting more involved and more raddical as well!

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

Cheers,

Hey guys not to bump this thread but I too am interested in changing out my enormous case fans to something smaller. But my problem is that these fans are defective. 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.
