Hi all!

Hoping to ask some of the more veteran people in here, I'm looking to replace the case fans in my CM 690 III and I'm looking for 140mm fans. Maybe around 3 pieces. Criteria I'm looking for are:

1) A good cfm/noise ratio, (I know more cfm = more noise so I'm looking something that has a good combo)
2) PWM fans preferred
3) Non-led black fans preferred
4) I have a budget of roughly RM50 per piece
5) And hopefully something with a nice build qualiy

I've been google-ing here and there. And I found some that interests me, but there are some that I can't find in lelong such as the cougar vortex 140mm fan. Or do you guys have any other suggestions?

I'm very open to suggestions

Thanks in advance!

Thanks for the suggestion! I've had a look at the CM JetFlo's and have taken interest to it, but I'm really keen on getting 140mm fans. One main reason that I'm opting for 140mm is as I have read, bigger fan=high cfm at lower spin rates. And I'm preffering PWM and preferably not going for fan controllers so I can just change it using software and because I'm just plain lazy(and most of all afraid that I forget) to go change the fan speeds during an insta-go-play-game-heavily-for-long-hours session. lol xD

You got the CM690 III thumbs up bro! Kita geng! ;D

And also in your second pic, I saw a cable running through the side of your HDD bracket, with some sort of resistor? perhaps. May I know what it is?

LOL me so noob >.<

Luckily my mobo got 5 (1cpu+1opt+3sysfan) headers
Gonna go for a nepton 240m soon, so that leaves me with 3 left. And unluckily my exhaust fan suddenly died today (as if it knew I was looking around for a new fan) T.T
