ovladanie CPU chladica na K9A2

Ahojte, potreboval by som poradit. Neviem si dat rady s nastavenim regulacie ventilatora na CPU na auto. Nainstaloval som si SpeedFan 4.51 Ventilator ktory mam vzadu v bedni som dal na SYSFAN1 a vpohode reguloval cez ten program. Ale ventilator na CPU (3pin) sa mi vobec nedari ovladat. Ventilator bezi stale na 100% (2700RPM). Neviem ci to treba este niekde niako specialne nastavit? Pred tim bol zapojeny na toto https://www.alza.sk/zalman-fan-mate-2-d101890.htm#popis ale rad by som to mal regulovane automaticky. MB: MSI K9A2 Platinum. Pozeral som specifikaciu MB tak ma tam pin - senzor... Dalsia moznost je smart fan ale to neviem ci ma take moznosti regulacie...

3 pin nejde ovladat, ovlada sa prave cez ten štvrty

no piny by mali byt: GND, +12V, Senzor, Control. Napriklad ten SYSFAN je tiez 3 pin (GND, +12V, Senzor) a vpohode ide regulovat pomocou napatia (ak to spravne chapem...) Alebo v 4pin porte sa neda menit napatie?

A skúšal si pozerať nastavenia v Configure -> Advanced?

Ano, pozrel som sa ze CPU cladic by mal byt chip F71882F. Tak som siel do Advanced a skusal... ale bez zmeny teraz je tam nastavene
PWM mode 1/2/3/4 - Manual set PWM
PWM Type 1/2 - PWM mode (4-wire) / skusal som aj 3-wire
PWM Type 3 - Linear DC
PWM Type 4 - PWM mode (3-wire)

Co by tam spravne malo byt?

Neviem ake su moznosti, tento cip nemam ani na jednej z dosiek, ale vsade chces ten DC mod. Kazdopadne je mozne aj to, ze DC regulacia na tom konektore v tomto pripade podporovana nebude. Riesenim by bolo vymenit ventilator (co sa u zalmanu asi nebude velmi dat), alebo si mozes zosmodrchat "prevodnik" z PWM na DC, cim vlastne zo svojho 3-pin ventilatora spravis 4-pin (len s externym regulatorom).


(nevyskusane, prva "schema" co som nasiel).
