fans spining up and down randomly during any amount of load that is not idle

[mangeHD]

so i wanted to make my pc sound less like a semi-truck so i went by linus suggestions and i got noctua fans but not any noctua fans i got noctua ippc 3000rpm pwm fans and i can say that for the like 30 seconds i got it to work they are quiet or what you may even consider silent but as my luck is bad first i downloaded ai suite 3 and got blown away by how shit it was so i uninstalled it with a tool i got from asus website but even when putting it right in to the uefi bios of my asus z170-a it did the same thing then i prosseded to flash my mobo to the newest version and guess what.....    that did not work either it still just put the fans to max about every half an hour and not untill i had went through every forum there is i found speedfan and finally it did not put the fans up to max at idle....... but under any kind of load it is a whole other story to be honest it was not as bad as before but now the things went to max every 10 min and stayed there for 30sec-1min but that just pure bullshit because i spent about $140us on buying the fans and i cant even set a fan curve that is not bugged to shit? so for all my fans the curve looks like this

 

except for the lower front one that looks like this

 

 

 

 

i'll list some specs for you so maybe the ltt community can help me once again

cpu i7 6700k 4.5gh oc with adaptive mode

gpu gtx 970 strix

ram 32 gb corsair lpx 2666mhz

mobo asus Z170-A

psu evga 1000gq 

ssd samsung evo 500gb

cpu cooler : coolermaster hyper 612 ver.2

fans 3x nf-a14 ippc 3000rpm pwm and 1x nf-f12 ippc 3000rpm pwm

 

p.s. the max speed in % for all the fans are 25%

 

i would apriciate any help i can get with this as a dont really want to return the fans as i know they are 100% functonal

For one, Noctua iPPC 3000RPM are not silent fans.

 

Most fans don't move at 10% voltage, which is what you have them on most of the time. Go from 0% which is guaranteed stop, to 30% which is guaranteed running. There's also the hysteresis number, that's the number of degrees that speedfan will let the fans go down before adjusting the fan. If you turn it up, the fans will tend to stay at the higher RPM setting for longer.

well, first thing you did wrong was getting the noctua 3000 rpm fans expecting silence. You want the nf-a14 pwm fans for silent performance http://noctua.at/en/products/fan/nf-a14-pwm  You don't really need a ton of air pushing through your case, 80% of the cooling battle is just having airflow, ~10% is air flow dynamics, ~9% if you have air directly feeding hot parts, and the last ~1% is how much air you push. But seriously the industrial fans are relatively silent for server type stuff, but loud as hell for regular computer users

well i set everything too 30 straight on the cpu fan and then it goes up to 30 on all the others at about 50 degrees and this does not sound to bad im just going to see how it does under load
