140mm fan for radiator

[Tsumi]

So I got myself a HWLabs Black Ice GT Stealth 420 radiator, one of those with a ridiculously high FPI, so static pressure would be more important than airflow. It is a 3x140mm radiator. I'm in need of some suggestions for fans (prefer performance over noise, but not overly so, would like somewhat of a balance). I will be using a fan controller, most likely one of those Sidewinder rheostat controllers, since I will be modding my case. The door on my Cosmos 1000 makes getting to the fan controller a pain, so I will be modding the top to accept two of those rheostats. I am also somewhat on a budget. I will need 4 fans, as I already have 2 Aerocool Silver Lightning fans.

I was looking at the Yate Loon D14SH-12 fans, with 140 CFM ratings. On PerformancePC's, they have a fan speed rating of 2000 RPM, while on the Yate Loon site, they have the RPM at 2800 RPM. I'm more inclined to believe it's at 2000 RPM, a site suggested that it really spun at 1800-1900 RPM, and that it also has really poor static pressure. At around $5-8 each, they're not a bad value.

Then I looked at the Koolance 140mm fan offering. It spins at 2200 RPM, has a max airflow of about 91 CFM, and a static pressure of 1.9 mm. These go for around $15 each, so for each one of these, I can get 2-3 Yate Loons.

After researching a little more, I decided to take a look again at the fans that I already have, 2 140mm Silver Lightning fans. These are supposed to spin at 1500 RPM, airflow of 73 CFM, and a static pressure of 2.05 mm. Initially, I didn't even think about these fans, because I saw 0.081 as the static pressure, which seemed really low. Then I realized it was in inches, so I found the conversion, which is approximately 2.05. It's the highest static pressure that I can find for regular 140mm fans (the Yate Loon is still an unknown). But at a cost of $16, it's the same story as the Koolance fan.

So, any suggestions on what to go with? Any advice/input would be appreciated!

Oh, and leave out the Noiseblocker fans altogether. $25 is way more than what I would like to spend on a single fan.

Do the Silver Lightnings give you the performance you want at a tolerable noise level? If so you could just go with more of those. At least you know what you're getting.

As for the Yate Loons, they are cheaper, but with low static pressure they aren't very good rad fans. What you could do is buy double the Yate Loons and put them in push pull on the rad. Having 6 fans on the rad, I think would make up for the lower pressure. It's really up to you, what you want to do with it. Nobody said watercooling would be cheap.

Well, I am going to do push-pull regardless of the fans I use. It's looking more likely that I go with 6 Silver Lightning fans. Just wanted input/advice, especially if anyone else knows any good 140mm radiator fans. Having the Silver Lightnings at 40% on my NZXT fan controller is virtually silent, and on max they aren't bad either.
