I am big on the Noctua NF-F12 fans and I have three on my Monsta 360 running at 100% and I can barelly hear them. I can't say much about the Vardar fans as they were not in production when I put my loop together. I may give them a try someday as I have seen nothing but stellar reviews about them.

I use some Cougar Vortex 120 mm fans too but they are louder and I use them on the 240 radiator in the top of my case to keep the noise down some: http://www.newegg.com/Product/Product.aspx?Item=N82E16835553002
 

Great suggestions so far. What are you after good pressure, low noise ,or both? I'm disappointed to hear about the noise from the Vardar fans. I have always been looking for a good replacement for the AP-15's. I like the Corsair line-up, and some of the Noiseblocker series.  You have to really pay attention to the Corsairs, as far as PWM /not PWM, and also the spec's. I like these:

I would recommend to run a fan controller regardless for fine tuning.

I think I'll order those Noctuas.

If you're mouting them on a top radiator you can't see them anyway so the color doesn't really come into play for you. I was using those white bladed fans from my Swiftech H220 on my top 240 mm radiator until one got noisy. The Cougar Vortex fans work better but once again the orange color of the blades is annoying to me so I put them up top where I can't see them. Corsair makes some nice case fans that I use on the front and bottom of my case for intake. No high static pressure but they move plenty of air through the case for me which is what I was looking for anyway. Having cool air blowing across the backplates of my EK full cover blocks lowers my temperatures considerably. The EK backplates have a machined area to assist in cooling the VRM and VRAM using thermal pads and cool air blowing across them makes them much more efficient.

It will be mounted at the rear of my case so it will be visible. 

It's hard to find a high static pressure fan with LEDs if anyone even makes one since most high static pressure fans are buried under or attached to a radiator where lighting woulld be difficult to see.

I have trouble when choosing a fan for the highest static pressure available since manufacturers use different measurements making it difficult coverting the volume of air being pushed. Using the Scientific Unit Conversion calculator built into Windows the conversions I come up with are way off target or I just don't understand the concept. I see cubic cm, cubic ft, cubic anything that sounds bigger than something ellse. I really wish they would standardize the flow and pressure ratings for all manufacturers then enforce them to adhere to the standards.
Here are my Cougar fans in action and there is no way to see them unless you really contort your neck. IDK but orange fans just don't seem to fit any color scheme I have ever seen. I don't mind the Noctua fans being visible since anyone who knows anything about PC fans recognizes the signature Noctua color and knows they are high quality.

Believe it or not, I had two of those fans on my Megahalem a few years ago. I used to fold 24/7 when I lived on base. I would run all the fans in that rig at 100% all day lol. I had 2 GTX 460's folding alongside this i7 and another LGA 775 rig with 3 GTX 260's and a 9800 GT. My tiny dorm room was a sauna that sounded like a server room.

Corsair has some magenetic levitation fans that just came out that are supposed to be best of both worlds and there are with and without LED's. They are ridiculous expensive though. Corsair ML series

+1 Just read the review by our forum member vsg28. <<[I'm a bit slow] Great review! I would like to try them but they are pricey, though seem quite good. http://forums.evga.com/Review-of-the-new-Corsair-ML120-Pro-fans-m2513437.aspx

I'll put a good word in for the EK Vardar series. They seem to give Noctua level performance and typically are around the same price, but with a nice look to them. I believe they come in black and a greyish color similar to old Gentle Typhoon fans.
 
The 1850RPM versions are what I have, they're absolutely silent at idle and whisper at full load. They move a LOT of air.
