" rel="nofollow - Hello from Poland. I have Z77 Pro4 motherboard and i noticed one issue. To be precisly, CPU fan control has a lag (i'll try to described well) I set target temperature on bios to 60c - then i run OCCT for test. Of course if 60 is reached CPU Fan accelerates from 700RPM (i set level one on Bios for idle state) to 1300 (I have Macho2 ver B) but all proces take too long - why im asking? Because when i start a test CPU temperature grows immediatly from for example 35c to 65c and higher in 10 seconds. Before motherboard noticed reach 60c and give information to CPU Fan "get faster" temperature on CPU they can reach 80c. All operation start CPU fan higher to max RPM takes 2-3 minutes. So my question is - whether there is a software or options can give immediatly signal CPU fan to speed up? In AMD motherboard i have stock cooler and when CPU is heavy load CPU fan immediatly start RPM to higher (not accelerating but immediately 100% RPM) and if CPU is done heavy load, immediatly fan is slow down. On Asrock, of course everything is work, but too slow. Thank you for answer :)

PS - I'll try to set CPU target temp to 50 trying to prevent rapid growth CPU temp, but is not an resolve for me, still waiting to CPU RPM speed up take too long
