In olden times, fan control simply wasn’t offered and all fans operated at maximum full speed. The various chips and processors inside a computer must be cooled, but more often than not, the fans tasked with the job are run at speeds much higher than necessary. Our comprehensive guide walks you through the complex configuration and allows you to unlock the full power of this enduring software utility, a favorite of SPCR for years.Īs fans are responsible for the vast majority of noise generated in modern PCs, fan control is a vital feature in the realm of quiet computing. I guess it is wired differently because no motherboard settings were changed.SpeedFan is a free, but extremely powerful and customizable sensor monitoring and fan control utility that works with a huge range of motherboards. It was on when the PC was powered up, and off when on sleep mode. The weird thing is that my old case did not have this LED behavior. :o: My H80i is actually the one with the SATA power cable: Of course that is what it’s doing when double flashing during sleep - distinguishing between power off and nap time. You don’t need the power button to tell you when the pc is on. Obvious fix is to pull the tiny wire for that LED from the block on the motherboard. The blinking power button during sleep is pretty common. I used VRM temp on my X99, but I don’t think that is a Z97 option either. However, I don’t think those showed up on most Asus boards until a few years later. If by some chance you have a 10K thermistor or temp sensor input (2 prong), you can run a sensor wire to the radiator exhaust to approximate coolant temp. You probably need to use CPU temp with a spin up/down delay (12 seconds). Yeah, the control variable is going to be less than perfect. The BIOS cannot take control through the cooler’s controller other than dimming the voltage across the entire package. That header still needs a 100% “full speed” signal from the board to keep the pump going (assuming this not the much older SATA powered “H80i”).
