Silverstone stated in the fan specifications that they should not be used with mother board fan headers. Was the fan being used incompatible with (any) mother board fan header, as was the case with the 180mm Silverstone case fan, in a fairly recent thread.

If you see a thread whose title is about a problem with controlling the speed of a fan, does that mean it is true? Did you read threads like that, to see what the outcome was? Meaning, was there really a problem or not, and if so, was it fixed? Show me these problems with three pin fan speed control please. I have so many different fans that I use and then change for another, I don't know how many fans I really have. I have at least 10 ASRock mother boards, and I have never had a problem controlling the speed of a three pin fan on any of them. Many people have problems with three pin fan speed control? I disagree. Just want some clear information on the mobo i want to buy. Why would you think ASRock would not have three pin fan speed control in their products?

Do NOT assume all boards will have this feature, check the specifications for 'Smart Fan Speed Control'. Some models allow some or all of the fan headers to monitor the CPU or mother board temperature to change the fan's speeds. Those fan headers can control the speed of both PWM and three pin voltage controlled fans. Many new model ASRock boards have mostly or all four pin fan headers for the Chassis fans. Actually, I've never tried a three pin fan on the four pin CPU fan header, since I prefer PWM fans. Only the four pin CPU fan header, or the CPU_FAN1 header, when two CPU fan headers are provided, will only work with four pin PWM controlled fans. That particular configuration scheme has not been used for several Intel processor generations.Īny of the fan headers on most ASRock boards, whether three or four pin headers, will control the speed of three pin fans. The description given above by Boltar is correct for some older ASRock boards. More expensive boards have more extensive fan speed control options and settings. The sophistication of the fan speed control available on an ASRock board depends upon the model of board, it is not identical for every model of ASRock board. Yes, of course it does! Controlling the speed of three pin fans with voltage control has been available for years on ASRock boards. So AsRock supports this speed regulation for 3 pin fans?
