Best fan EVAR!!

[doyll]

Like ehume, I think the TY-14x fans are fantastic, no pun.
I'm running TY-140 fans in my old Define R2. I had to modify the front to accept 140mm fans but end result is a very quiet case with great airflow.


I know a few people who modified TY-140, TY-147 or TY-147A fan for use in Define R4 with great results.

Like ATMINSIDE, I believe the use of good fans using CPU and GPU temps to regulate their speed so they cycle with CPU & GPU fans to supply smooth airflow is the best.

Here is a basic guide to using CPU and GPU PWM control for case fans.

If you use PWM fans with a PWM splitter w/ PSU power you can control their speed with CPU fan header PWM signal. Can use GPU fan PWM signal for some fans too but takes more adapters.

Controlling case fans with PWM signal from motherboard CPU fan header and GPU fan header.

There are some limitations:

• Obviously motherboard and GPU must have PWM
• Obviously fans must be PWM
• Motherboard can only support 8-9 fans (PWM signal strength gets too weak)
• No idea how many fans GPU can support.

Setting up motherboard PWM control of PWM case fans:

• Use a PWM splitter with molex/sata connector. Gelid and Swiftech are my preferred.

• Plug PWM splitter to motherboard CPU fan header and PSU
• Use CPU cooler fan as "master" fan. This is the fan that sends rpm signal to motherboard PWM header.
• Additional CPU cooler fans and case fans will ramp u and down with CPU fan.
• Can use a second PWM splitter on 3-way & 4-way PWM splitter.
• Setup fan speed curve with motherboard bios or software. Gigabyte has EasyTune 6 and Asus has SmartFan. I set minimum at 30% fan @ 30c and maximum at 100% @ 65c. Than watch temps and see if you want more or less rpm to keep temperature and noise where you want them. My sig rig idles 24-29c @ 700rpm; 100% all cores is 42-48c :950-1050rpm.

Setting up GPU PWM control of case fans:

• Obviously GPU fans need to be PWM. Because the GPU PWM header/plug is smaller than normal PWM we need a Mini 4-Pin GPU (Female) to Mini 4-Pin GPU (Male) / 4-Pin Fan (Male) Cable Splitter Adapter is needed-. The blue wire going to normal PWM socket needs to be cut off of mini PWM plug. (You can use this wire to monitor rpm on case fan by connecting it to a normal 3pin fan plug in the rpm position.) Plug a PWM splitter into the normal PWM socket and PSU for case fans.

• Case fans hooked onto this splitter will ramp up and down with GPU fans.
• Use GPU software or Bios to setup fan speed curve

For PWM control of 3-pin variable voltage fans there are two ways to do it:

• Use a Phanteks PWM controlled 3-pin fan hub. These are designed to use PWM control with PSU power to control and power up to 30w / 11 fans.

Personally I use these as case fans:
Noctua NF-F12 industrialPPC-2000 PWM
Noctua NF-A14 industrialPPC-2000 PWM

Then I control them all off of the CPU fan header with one of these:

The 2x 120mm in my Hadron Air do a great job pulling air through the case to get heat out from both the CPU and GPU.
Here though the added bonus is that they idle down automatically and you control all your fans off the motherboard's fan curve.

Agree with ATMINSIDE

I am running 4 of these in push/pull on my H110i. At 1300 RPM, I can barely hear them. The 4 of them are quieter than the ACX 2.0 fans on my graphics cards running at 50%.
