They always run at the minimum speed they're set to in the BIOS (the 'Thernal' option under the 'Power'tab). That's when I noticed that the case fans and CPU fans never change speed.

#Hwmonitor pro connection failed windows 8.1

I installed Windows 8.1 Pro on the new SSDs using the original HP installation media and the embedded Windows 8 product keys.

#Hwmonitor pro connection failed upgrade

I recently decided to add 240GB SSDs to run as boot drives and upgrade to Radeon RX 550 video cards, which I haven't installed yet. I wasn't using them for the last year or so.

I don't recall having any problems with the automatic fan speed control when these machines were running Windows 7. When I re-installed them, I used Arctic Silver 5 thermal compound. I removed the fans from the heatslnks to clean them and then reassembled them. I upgraded one of the processors (originally an i3-4330) to an i5-4570. I purchased these two computers in used condition about three years ago and I began refurbishing them at that time.

Under full load, the CPU power consumption is around 66 Watts. The CPU power consumption is around 4 Watts according to HWMonitor. When the processor is idle, the core temperatures are around 40 degrees C. I'm using Prime95 to put a full load on the processor. It also tells you the temperature of the 'Package', which may or may not be the same thing as TCase. I don't think HWMonitor measures the TCase or TJunction it tells you what the internal thermal monitor in each core is reporting. I'm using HWMonitor to see the temperatures of the cores. Thank you for any assistance you can provide. An older version of the BIOS cannot be installed. I noticed that they stopped working some time after I installed the latest BIOS, which updates the CPU micro code to fix the Meltdown security flaw. I haven't installed an unsupported operating system and my fans are not defective.It seems unlikely that the PWM thermal chip has failed in both of my motherboards at the same time.

Is there a proprietary HP driver required to make the automatic fan control function properly? I've read other reports in this forum from other users who have experienced the same problem but I haven't seen an effective solution. (HWMonitor reports fan speeds as long as it can read them from the system.) Third party programs such as SpeedControl don't work because the fan speeds cannot be read from the system. I've used third party programs such as HWMonitor to check the core temperatures, but I haven't found any program that is able to report fan speeds. The problem is, the automatic fan control is not working. Clearly, the fans are not defective (and they are very clean). If I set the idle fan speed to maximum, the CPU stays at a temperature of less than 60 degrees C even under full load but the noise is unacceptable. A low fixed speed is suitable for most applications, but under full load (as tested with Prime95), the CPU temperature can exceeed 75 degrees C. The case fan and CPU cooling fan always run at idle speed, depending on the speed I set for them under the 'Thermal Option' in the BIOS. I installed Windows 8.1 Pro with the original HP disks, using the embedded Windows 8.1 product keys. I don't know how the machines accomplish automatic control, but there is no option to change any settings related to that. HP documentation states that this option only controls the minimum idle speed of the fan, and the fan speeds are 'automatically controlled'. Under the 'Power' options tab, there is an option called 'Thermal' which allows you to set the minimum idle speed of the fans. The BIOS setup program for the latest L02 BIOS dated 4/19/19 offers limited options for thermal control. The case fans and CPU cooling fans are original equipment and they are capable of operating at variable speed when connected to a 4-pin PWM connector. I have the same problem with both of them, so I feel that there is unlikely to be an identical hardware failure in both of them. I have two different machines that are virtually identical.
