z420 doesnt increase fan speed as CPU temp goes up

HP Recommended
z420
Microsoft Windows 10 (64-bit)

As the title states. CPU temp wil go up to 85c and fans will stay at minimum speed. If i increase minumum fan speed in bios the cpu will stay cool but then my workstation sounds like a jet all the time and i would like to get that quiet idle. I have replaced thermal paste and clered all the dust out. The problem is pinpointed dirrectly to fan speed not increasing as cpu tempreture is going up. Any ideas?

 

I am running 64bit windows 10 with all hte drivers installed from the HP website.

in F10 BIOS Setup you can increase the idle fan speed.

You should also check if there is a newer BIOS available for download.

I can change minimum fan speed and it does make fan speed go up and cools my cpu way better bringing temps down, but doing it this way keeps my workstation loud all the time.  I also updated to the latest 3.9 bios and it didnt fix the issue

there is no reason to panic.

85 degrees is high but not critical for a Xeon processor.

If you increase the idle fan speed in BIOS the workstation should not be very loud.

Don't go up to the max, just one or two steps.

In case you have a high power graphics card there is a front fan kit which increses airflow a bit.

I have the same issue. The CPU fan will not throttle up when the CPU gets warm. I can manually adjust it from the bios, but.. shouldn't the fan increase speed when the CPU get warmer? I also updated to the latest bios. I have not updated the firmware yet. would this be the issue? should I go back to v3.88. could this be the issue? Is there a setting in the BIOS to turn that feature on?

I have the same problem (see below for specs) .

 

The fan can be increased via the bios but for runs at whatever speed all the time, No idle nor peak speed settings. Now I am running Thermal at 3. The PC is too loud. Running at a 2, the sound level is ok, but temp jump into the 60s to low 70s.

 

I'd like to know CPU temps; min, max, and normal operating range for this Intel CPU. I read various "opinions" online stating anywhere from 64C to 91C. 

 

Intel's site states "Case Temperature is the maximum temperature allowed at the processor Integrated Heat Spreader (IHS)." at 64C for Intel® Xeon® Processor E5-1650 12M Cache, 3.20 GHz, 0.0 GT/s Intel® QPI. I think this is what I have.

 

-Any info would be helpful.
