Product: hp Z620 workstation
Operating System: Microsoft Windows 10 (64-bit)
Hello,i have an hp Z620 workstation,and about 3 weeks,the error 513 front fan not detected.
I test the fan by using usb male to 4pin adapter,and the fan dosn't work anymore.
I replace the fan and the new fan is work by using usb adapter,but dosn't work if connected to motherboard.
The only i have change before it happen is removed the GPU Quadro 2000 2GB,and installed an radeon saphire pulse 4GB.
This AMD GPU i found when is on the fan stop spinning alternate 5 min on and 5 min off,
So i think is different speed control than workstation do,infact it dosn't deal with bios speed fan.
So i removed the GPU AMD and i reinstall nvidia Quadro 2GB.But the error still appear.
I think the 4 pin f mainboard have issues or some,but at moment i put an jumper,the error not appear,and i connected my new
fan to usb and running standard without control.Anyone Know what happen?
Please note,i am workstation HP user since 2009,and only different i find here the fan control on bios need restart to se the change,in my old Z600 or XW8600 XW8400,XW6400, all fans speed show up straight away,But not in this Z620,
I hope is clear and someone maybe can help Many Thanks
