Question Recommended Fan control software that overwrites BIOS?

[Cravez]

Hi all

Recently built a new PC couple days ago, with NZXT H9 Flow case, LS270 360mm Liquid Cooling, bunch of Artic P12 and P14 PST fans in regards cooling etc.

All with the computer is fine, however I've noticed the CPU fan connected with the LS270 cooler, and also one of the SYSFans (SYSFan 5), are running at far higher RPM (2500 and 5000 RPM respectively) than the other fans. Going into the BIOS and checking, I usually set Fans to Smart control so the fan speed is automatically controlled, however in these case of CPUFan and SYSFan 5 are smart controlled like the others, but they are not reducing their RPM. The Other fans are running at 900 RPM or so.

The temperature charts show that they should also not be hitting anywhere near the RPM given the current CPU/SYS Temp. I honestly don't know why these fans are running this fast and can't seem to change the conclusion in the BIOS.

Is there any good free Fan Control software that might be able to help for me to change CPU/SYS fan settings that will overwrite BIOS?

any help appreciated.

Hi
Have you checked what those headed are set to pwm or Dc voltage ?

You can try this that Jaztwocents featured.

He also did another video on doung some custom Ui with that software.

SW controls fans thru BIOS, if BIOS can't control it neither will SW.
Considerations for BIOS fan curve control.
Type of fan and header. 3pin Dc/voltage control or 4pin PWM. They have to match.
Some MBs and BIOS allow each header to control fans from different temperature sensor.
Don't mix different types of or speeds fans in same header.

First, as far as I can tell all software utilities that allow you to observe and adjust fan speeds actually use the mobo's fan control systems in BIOS to do their job. They merely change the settings of those mobo systems, just as you might do manually from inside BIOS Setup. So they do NOT replace the mobo systems, nor do they re-write the BIOS code.

Small point of info. I suspect your AIO system is a DeepCool LS720, not 270. Right?

Next, one bit of your post is hard to accept. You say the fan on SYS_FAN5 reports a speed of 5000 rpm. None of the parts you cite will run that fast. There are a FEW very high-power fans not commonly used in computer cases that can do that, but you do not say you have any of those. You can get such readings (but wildly fluctuating) of you have two or more fans connected to a single header without using a proper fan Splitter, but you don't say anything like that, either. You MIGHT have a bad connection on that header OR it may be faulty. Have you tried swapping any other fan onto that header to see if it changes things?

Regarding the CPU_FAN header speed, with that AIO system the speed you get in BIOS Setup on that header is the PUMP speed, not the rad fan speed. That
AIO system says its PUMP speed is normally fixed around 3100 RPM. So if that is what you read, that is normal.

It is not clear from the DeepCool LS720 web page how the RAD FANS for that system are controlled, nor how you might "see" their speeds. Those speeds may NOT be displayed anywhere.

Hi all. Thanks for the replies, and sorry for the confusion in stuff. I'm still not 100% familiar in regards cooling and how properly it works etc. I decided to switch some fan headers and de-couple some fans connected together and runs a bit better now. i was more concerned with the PUMP fan running at 3000 RPM but if that's considered normal and fine then I'm okay with that. Maybe I might invest in some Artic P12's to replace the stock LS720 to try reduce the noise a little.

Thanks again.
