Same in my case at 40%. I have it at the moment at 30% and hopefully this is enough. The noise is ok, but could be better and for me i will try a little bit lower, but do not know if this oculd be too low.
This is my system at the moment and i have some things to do and some things to figure out the right solution. I hope you can help me, because i saw some of you are using the Z87 Stinger, too.
At first the picture:
What to do:
-crimping and soldering the pump and the LEDs into the molex 4-pin cable.
AND now the point where I need your help^^
- regulating the fan speed!!! ... In the UEFI of the Z87 Stinger i can only switch to a fixed %-value. So i took 50% which means approximately 460rpm. I do not know if this is enough in gaming and i would like to edit something like a fan-curve. I tried SmartFan, but there I can only choose a fixed value, too. Do you have any hint for me?
edit: really nice setup cncept! like your tube routing!
