Delta Fans
#1
Hi,

I plan to replace my current front and exhaust fans with Delta's but confuse which model to choose. From searching the forum, I found 3 models being suggested:
  • AFB1212GHE
  • QFR1212GHE
  • FFB1212EH
My current rig are now running with 3 x 120mm front fans and 1 x 120mm exhaust fan specifically model Jetflow 120 from CoolerMaster (95 CFM, 800 - 2000 RPM).

What model of Delta fan will be suitable for my rig?

Oh and by the way, I'm using Thermaltake Commander F6 fan controller that can support 6 channels (30 Watts each).

Thank you.

You do not want to use deltas unless you are housing the box in a datacenter or have some sort of noise cancellation. Go with noctua's NF-12's instead.

i am not an expert in fans but why NF-12?
his fans run at 2000RPM, 


looking at http://noctua.at/en/products/fan

most of the NF12 series are below 2k rpm, only the  industrial ones are above 2k rpm, actualy only 2 of them has higher RPM than his.

RPM is irrelevant. What matters is the CFM and static pressure. And dB if this is in earshot. And also the power draw in this case since for some reason he's using some fan controller that only supports 30W fans (when most serious fans are like double that.)

If noise level and power is not an issue what will be the recommended model for my setup?

  • AFB1212GHE (Max CFM 240.96, Static pressure 1.082, 29.40W (max 38.88W))
  • QFR1212GHE (Max CFM 210.38, Static pressure 1.170, 21.60W (max 32.40W))
  • FFB1212EH (Max CFM 190, Static pressure 0.700, 24W (max 36W))

I personally have and have used a bunch of PFC and TFC 120mm Delta fans(the closest from your list would be the AFB) and they draw close to 50W from my experience. I had to buy a special fan controller that could do 60W/channel. They are also 252CFM and a screaming 66-70dB. Considering your application and also your case design, you probably dont need insane static pressure since there's nothing up against the back side of the fans that could cause major back pressure(i.e. radiators). Higher CFM does mean better airflow but at some point it doesnt really have much of an effect if that hot air is just being dumped into the room again. The different between the 190CFM fan you listed and the 240CFM fan will likely not be that noticeable, especially with your case design. The most noticeable thing you can probably do for heat after adding intake fans is back up a fan or two to the back of the case and draw the hot air out of the back tips of the cards more effectively. I've done that before and it has made a much bigger difference in desktop style cases like this than forcing air into the cards from the front tip. If you had a sealed up rack style case, forcing air into the cards would be much more effective.
