R6 Define - Improve GPU-Cooling & Use fan-hub
Posted: Thu Aug 08, 2019 2:02 am
Hi!
Im building a quiet build with a Define R6-chassi. I wish to be able to control the three included stock fans (Fractal Design Dynamic X2 GP-14 140 mm) with fan curves to avoid having them spinning at 1000 rpm all the time.
As I learned from another forum, the fan hub can be used by connecting it to a CHA-FAN input and then set fan curves based on for instance MOBO-temp (and having the CPU-FAN separately connected to to just the cpu-fan, which is a NH-D15). BUT, to be able to use the stock fans (non-pwm), i need to atleast input 1 PWM-fan in to the hub. I have a B450 Tomahawk MAX motherboard, does anyone have any experience with this combo?
Plan:
1. Replace 1 front intake fan with another premium fan to 1) Increase static pressure at 2) a lower noice level. My intent is to replace the lower fan to a higher performing fan and then directly aim this 140mm fan at the GPU (which is the R6 weak point).
2. Place the removed stock fan as a bottom intake fan as far in the chassi as the PSU will allow and then cover up the remaining mesh (from the fan towards the front) with cardboard to remove any posibility of cold air leaking out the bottom (big cred to Teodoro who did thorough testing on this viewtopic.php?f=15&p=610653#p610653). I will also raise the chassi 5-10cm above the ground to improve airflow from the bottom for the PSU and the bottom intake fan.
3. This would leave me with 3 intake fans (1 Stock in front, 1 Premium in front directed to the GPU, 1 stock in bottom) and 1 fan in the rear blowing air out.
Questions:
1. Thoughts on the plan?
2. Never modified a chassis fan-curve before. Any tips on how to think when testing out and optimizing the fan curve? Recommended temperature reading to base the chassi fans on? (heard that CPU is a bad idea to the aggresive temperature changes it goes through). Can i just do it in BIOS for the MSI Tomahawk or should I use a software?
3. What Premium Chassi Fan? I want to increase the airflow to the GPU and want it to be more silent than the stock fans. Based on these forums and other I have kind of narrowed it down to the following options and I've added some specs whereof I assume that the static pressure is the most important for a front intake case fan?
a. Stock Coolers (Comparison) - 1000 rpm - 18,9dba - 0.71 mm H2O static pressure - 68.4 CFM
b. Noctua NF-A14 PWM 140mm with LNA - 300-1200 rpm - 13,8-19,2dba - 1.51 H20 static pressure - 52 - 82.5 CFM
c. Be Quiet! Silent Wings 3 PWM 140mm - max? 1000 rpm - Max 15,5dba - 1.08 mm H20 static pressure - 59.5 CFM
Based on this, the Silent Wings 3 would increase the static pressure would by 50% while reducing the maximum by ~20%?
The NF-A14 would increase static pressure by +110% while increasing maximum noise by 0,3dba (while lowering it when not maxed out)
What do you think? I can get the NF-A14 for around 21 EUR and the Silent wings 3 for around 25 EUR.
Thanks alot!
