Asus Fan Xpert says my CPU fan can only run at 90% ...

Hi folks!

 

ATM I'm trying to reduce the noise coming from my rig ...

However ASUS FanXpert doesn't let me set the CPU cooler to less than 90% ...

 

I'm using a Noctua NH-D14 with both low noise adapters on a i7-4790k (ASUS automatic OC to 4.6GHz) on a ASUS Z97-Pro Gamer motherboard.

After having run "Lüfterabstimmung" (german ... which should translate to Fan Attunement) I cannot set the CPU fans to run below 90% ... which is really annoying.

Btw: the ASUS Z97-Pro Gamer has 2 CPU_fan headers, which I've both used for the NH-D14s fans.

 

Currently the CPU sits at 23°C right after boot and at 30°C after an hour of gaming ... apart from Prime95 i've not seen the CPU temp go above 35° so far ...

So there is alot of head room for my fans to spin slower, but the ASUS Suit doesn't let me slower the fans ...

what's going on and does anybody have a clue as what i could do here ? ^^

And pls don't suggest to exchange any components of my rig, i could not afford it.

 

Thanks!

 

PS: as was thinking of removing the preinstalled rear fan from my case (be quiet! Silent Base 800) and put it in the bottom next to the PSU as additional intake. this way only the NH-D14 would blow air towards an "exit" ... would this be wise?

 

PS2: oh, and you should be able to see the rest of my build on my profile.

Uh...

I'm not sure.

 

Try messing around with the fan settings in your BIOS and make sure that there's nothing obviously wrong. 

 

I'm not sure how wise removing the outtake fan would be. Someone else can probably answer that.

What's the tachometer showing for the fan rpm? The low noise adapters are just resistors that lowers the voltage at the other end for the fan.

For example: the regular low noise adapter would lower 12v to 7v so that 10.8v (90% of 12v) would end up as 6.3v (90% of 7v/actually 52.5%).

as shown in FanXpert3: 90% and 870-880 rpm for CPUfan and CPUopt ...

Yeah--it's the low noise adapters. 

90% of 1200 and 1300rpm is 1080 and 1170rpm.

I wouldn't add extra intake unless you are having problems with cooling GPU. You can disconnect it and see how your temps change but bottom intake rarely have any real effect on cooling.

 

As for control problem. Updating BIOS and checking that there isn't any conflicting settings in there is good way to start solving this.

kk ...

 

would it be an improvement to get rid of the low noise adapters since the motherboard can handle fan speeds or would it be wise to add PWM fans to the cpu cooler?
