So you want quiet high airflow high pressure fans Me thinks that's a pie in the sky. biggrin.gif

You might have better luck asking over in the water cooling forum
http://www.overclock.net/f/61/water-cooling

A mate has a VTX3D Radeon HD 7950 X-Edition in an Define R4 that we made quiet. All case fans are PWM with 2x front intakeTY-147 fans controlled by CPU fan PWM signal and bottom intake TY-147 controlled by GPU PWM signal. The GPU radiater was 240mm long so we took the cover off of the GPU radiator and mounted 2x Arctic F12 TC fans on it (used them because it was all he had) with pull-ties. We figured the F12 TC's would be temporary but with the sensor between the cooler and board they work great. GPU went from screaming load to quiet and temps dropped from 70's to mid 50's ultra setting solid 60fps. We did raise the base so he has 45mm clearance for fan intake airflow. wink.gif

I recommend Scythe Gentle Typhoon 1850 RPMs for 120mm fans, and Corsair AF140mm and Cougar Vortex 140mm PWM for 140mm fans. Noctuas are fantastic, as well, but really ugly. They are pretty much the best fans, though. NF-F12s for 120mm, NF-A14 FLX for 140mm.

I probably should have posted in the water cooling forums. The reason why I posted here is due to the fact that liquid cooling is a near future endeavor. It was something I wanted to keep in mind nonetheless with some fans costing around $20.00 each. I am well aware that there is a trade-off of loud noise with a combination of very high CFM and pressure. Delta fans are a good example. My opening posts do indeed appear to be asking for exactly that. In actuality, I am looking for a good balance of all three instead of nonexsistant perfect fan. Exaggerated manufacture ratings do not help with the decision process. lol

Too bad there is not a Noctua NF-F14. I thought choosing a computer chassis was hard. sonic.gif

I would rather have NF-Pxx than NF-Fxx EDIT Should be NF-Fxx than NF-Pxx. Reason is Pshould be F will move air with resistance when F should be P won't . All we every see is maximum static pressure and maximum cfm. Simply running a fan on a bench develops a little pressure differential between intake and exhaust... put it in a case and that differential is much more.. grill, filter, fan, HDD cage, cables, etc.

Silverstone has a nice little writeup and data on how much resistance just the grills produce:
http://www.silverstonetek.com/techtalk_cont.php?tid=wh_chessis&area=en

At maximum static pressure there no cfm!!! Static is stationary, no movement.

We need to see a graph of static pressure vs cfm. Than we would be able to see how much air the fan actually moves.

This chart was done using a Silverstone SST-AP121 fan; 35.36cfm, 1.72mm H2O.
The exhaust air ratio is the percent of air that goes through... grills loose 30-70% of airflow with a 1.72mm H2O static pressure fan!! Remember more static pressure the fan has the more air it moves against resistance of grill, filter, etc. Still want a fan that has low static pressure rating? wink.gif

I think you mixed up here.

Anyways, the problem of the NF-F12 is that it performs poorly is pull configuration so not really versatile if you want to use it on a rad. I'd go straight with GT's personally.

doh.gif I sure did.. redface.gif I just had it hit me and was going to change it... you caught me first. thumb.gif I will edit my original and hope nobody took my word for it before I got it corrected.

Some days it doesn't pay to get out of bed. doh.gif
