How can i increase fan speed?!

post #1 of 5
Thread Starter 
I recently updated my bios and had a few problem but mostly it let me fix a bunch of others. I was finally able to connect my 120mm fan to my motherbaord without getting the error but now its going much slower that it was before, i am actually looking at two of the same fans and you can see the spped difference. Sppedfan is telling me that the 120 mm fan is going at about 390rpm. (im talking about the fan that comes stalk at the rear of the half 912 case if any1 has it.) Another thing my cpu fan i think its 60mm and its spinning very slow and my cpu is pretty hot core 0 is always over 50c(even when at idle) speedfan says its spinning at 1500 rpm, I have a 2 year old hp computer so i am not sure if i can do anything in the bios. Is there a way i can speed up the fans. OH and the cpu fan's rpm never changes..., its always between 1500-1600 rpm. All help is appriciated thanks!

The simplest options would be to bypass the motherboard entirely. Just hook the fan straight up to a 12v molex or get a fan controller.

Something like this will work but your fan will always be at 100% speed.

If you want it to be slower you should get a fan controller. Then you can have manual control free of any software.

You can bypass the fan error message in the bios (at least you can on mine). My motherboard lets me boot even with the fan error message. I just have to press F1 to acknowledge the error. Not sure about yours.

I don't have a single fan running on my motherboard. All are directly on molex or a fan controller.

I have a hp pc lol, mabey thats why, i can bypass the system fan error, but not cpu fan error and what gets me mad is that the cpu fan speed never changes, is there any program that will adjust fan speed beides speedfan?
Oh and dont you find it annoying to have to press f1 every time you boot? thats why i have that one fan pluged in, the problem is that i think my motherbard only works with that fan, if i swich it out i get the wrror again, thats why i dont want to which my cpu fan out i think ill get the same with that.
