Hi! I'm having problems with the fan of my CPU. It always cycles at more than 3300 RPM and generates some noise. It doesn't matter if I enter BIOS or boot Windows, it always runs at full speed. This is my system: - Motherboard: AsRock H81M-VG4 - Processor: Intel Pentium G3250, Socket 1150LGA - CPU Cooler/Fan: Intel Stock E41998-002 "Delta" - No case fans or GPU fans - RAM: 12 GB DDR3 - Internal GPU - Windows 10 - All latest AsRock .INF drivers have been installed What I have tried already: - In BIOS: - I set the CPU fan from "standard" to "silent", no difference - I updated the BIOS to version 1.5, nothing happens. I have also updated to the beta version 1.7 but I still cannot control the fan speed. - Installed A-Tuning and performed a test with "FAN-tasting Tuning". The table of results show that at 10% the fan speed is 3384 RPM and so on until 100% with 3402 RPM. All the percentages are similar, always above 3300RPM. Changing the points in the graph and clicking "apply" has no effect at all. - I installed "SpeedFan" to see if I could change something, but nothing seems to have any effect. Please, your help will be greatly appreciated. |

Hi RLGL. The temp of both CPU cores is always between 35 and 40 C. Thanks. |

And when the PC is idle the temp of both cores falls all the tiem between 25 and 27 C, no more. Thanks. |

What header do you have the fan connected to? Try it on other headers on the board and see if that will allow you to control the speed. -------------

Hi Xaltar. It was initially connected to the CPU_FAN1 (number 21). Then I followed your suggestion and connected it to the CHA_FAN1 (number 15), and I set the Chassis fan in BIOS to "silent" but nothing changes. The Fan is still spinning at more then 3300RPM. A-Tuning reports the same speed. Here's an image of my motherboard layout and the headers I mention above: https://paste.pics/IGN5X" rel="nofollow - https://paste.pics/IGN5X Thank you in advance. |

I just bought a new Fan: DeepCool CK-11509: https://www.deepcool.com/products/Cooling/cpuaircoolers/2021/14443.shtml" rel="nofollow - https://www.deepcool.com/products/Cooling/cpuaircoolers/2021/14443.shtml Unfortunately, this new fan also operates at maximum noisy speed. In UEFI settings I selected again "Silent" but it has no effect whatsoever. The "A-Tuning" app shows it's rotating almost at 3000RPM all the time. The "Fan-tastic tuning" test shows almost the same values for 10% and 100%. The CPU temp is always 31. Please, is there anything that can be done here? |

Please, can someone confirm that this Motherboard model "AsRock H81M-VG4" just cannot control the CPU Fan speed whatsoever? As I mentioned before, I have tried everything with no success. Is this Motherboard model designed to make the Fan run at top speed all the time? Thank you. |

| As far as I can see on the asrock product page for this mb, your board supports CPU Quiet fan. So as long as you have a 4 pin connector on your cooler, you should be good to go. Have you tried resetting cmos or updating the bios? If those things don't work, I'd start looking for a replacement board, it seems like some controller is broken on it in that case. |

Hi Tom, thanks for your answer and help. Yes, I have a 4-pin connector on the fan. I also bought a new fan with no success. Yes, I have reset the CMOS and I changed the battery. As I mention on my first post, I updated the BIOS first to version 1.5 and then to beta version 1.7. I also thought the board could be faulty, but I have 2 PCs with the same identical board and both of them have the same full-speed-fan problem. It's frustrating. |

You could update to the beta BIOS but there is no changelist in the archive. It may fix the fan problem or it may brick things. You do have a recent CPU for that BIOS. The beta BIOS is from 2018 which is 3 years after the last non beta BIOS. :-) ------------- ASRock B450M Pro4 16 GB DDR4, 500 watt PS, AMD Ryzen-5 5600, NVidia GTX-1050, 5.70 BIOS |

Hi bjlockie: Yes, I had already updated to the latest Beta BIOS, as mentioned on my first post. The version is Beta 1.70, date 2018/5/30. I performed this update on both PCs (no success). The processor on both machines is Intel Pentium G3220. Thank you. |
