CPU fan Reving up and down again ?help.

scotslad · 9 Jan 2016 at 19:12

I am already tired of hearing my CPU fan reving up and down when just using the computer for general use which is more or less idle apart from web pages and watching some videos which don't really make it very warm even, the CPU temp fluctuates between about low 20's to 30's under the said conditions.

So to me the fan is sensing slight changes in temps and adjusting up and down etc, it is a little annoying the noise, my case fans are near silent so they are no concern, its the stupid CPU fan for sure.

I am pretty sure I set it to manual in asus Qfan control in bios.

Question, is there a way to get the CPU fan to remain more solid and at a constant Rpm rather than this reving up and down etc ?

If so could you please say how as I cant see how ? thanks.

(main parts of my system are in my signature)

Hav you tried to set the Qfan control to silent ?

yeah, I think that makes it even worse from what I remember, maybe its sensing warmer temps and keeps jumping up or something, I tried the corsair link thing too but that's pants man.

How many fans do You need 120mm i guess 4pin or 3pin ?

Errm, I think the corsair H80i GT is 4 pin, or is it ? hmm, think so.

What is your case fan setup?
What specific fans are cycling up and down in speed?
What are your CPU and GPU temps?
What are your CPU and GPU cooler intake air temps?

its a Fractal Node 304 case (ITX) with its two front fans ( https://www.overclockers.co.uk/fractal-design-node-304-htpc-chassis-white-ca-024-fd.html )

And simply a Corsair H80i GT sealed loop rad system but only with one fan as I am restricted to space in this tiny build which is otherwise great.
( Corsair H80i GT Hydro Cooler )

With regards the temps I am not 100% sure to find out what exactly you ask, I can however say that Aida64 tells me the cpu temps as I type this are approx 23 to 26-28-ish on the cores and that's in a room that is approx 25C warm just now with central heating on etc according to my desktop thermometer.

You may need to disable fan control on the CPU_FAN header to get the Corsair link software to work correctly.

why doesn't the bios fan control seem to hold the fan speed steady though ?

and do I disable the cpu_fan header ? and could that make it work better in the bios Qfan too ?

I had that happen with 3 corsair H80's. RMA'd them and they said they were faulty. Was the pump each time.

were they the H80 or H80i GT's though ? different units.
