Bit of a shit title because I’m not sure how to word what I’m asking sorry. As a bit of a pre cursor, every single pc i’ve ever had run windows 10 reports 100 degree temps in all software other than the bios, so once booted it thinks it’s hot.
Anyways PC go boom, new gpu, new psu, new mobo. Now my case fans seem to run at 100% all the time. I’ve tried Speedfan but it seems incapable of controlling the fans anymore. Also there doesn’t seem to be a max setting in bios only a minimum one (asus).
I’ve used the exact same fans with speedfan before in the same setup and the last thing I’m wondering is could it be the fan header ? Surely all headers support controlling fan speed it seems a given ? It’s driving me nuts sitting next to a jet engine 24/7, I do have a fan controller for half of the fans but the ones causing trouble don’t have molex which my fan control only supports.
Oh yeah heatsink is perfect. It just always reads it as 110 in Speefan/HWM/Speccy etc. If I installed win 7 it would show the actual reading as it does in the bios. Kind of a strange error but I’ve had it on 3 different Win10 systems now.
It’s a cheap Asus board, H81M-P-SI. The problem is it causes the fans to max out. Before i replaced the board I just used speedfan to set the fans at 50%.
Installed the probe driver and ai suite and it lets me adjust the cpu fan but the chasis fan is stuck at 1450rpm (or something like that). I disabled the q fan control in bios and same results. ** in the little preview picture for fan xpert the cpu one looks just like that but for the chasis fan it shows an exclamation mark and no points on the graph.
Something seems to be locking the fan speed. Which is probably why speedfan was redundant. I know these fans can be adjusted with software because I’ve had them working before. Ah well will try again tomorrow.
Depending on the motherboard - or even depending on the specific connection on a given MB - you may only be able to control the speed of 4-pin (PWM) fans.
If its not a 4 pin fan (PWM), and just a 3 pin, then the only way to dim the fan is with a manual reduction in voltage. Some mother boards won’t support this functionality.
