HP z420 workstation fans loud after GPU upgrade

[Davidross0904]

Thanks DGroves. However, the fans started to be loud just after the bios loads (or even in the bios) therefore operating system is not a factor. Even at 0% CPU load, the fans are at 1500RPM according to performance advisor, and this problem happens when using a GTX GPU (1650s) with the workstation. Before changing and even changing back to the original quadro, the fans are almost inaudible (all fans at 600rpm), compared to a loud hum and resonance after the upgrade(CPU FAN: 1000RPM MEMORY 1300RPM, REAR FAN 1550RPM). Is there any fix? I tried upgrading to 0.91 for the bios from 0.90 since another person says it fixed the problem but didn't for me. After the upgrade, before the computer rebooted, I did a CMOS reset but it didn't help either. Therefore it looks like a GPU problem or some incompatibility between the Quadro and z420. Is there some whitelist in there? it looks like the idle fan has increased greatly after the upgrade, even though the inside of the case is rather cold and the temperature sensor works. Is it that the GPU is not reporting fan speeds back?

Basically, i just want the computer to be as quiet as it was with the quadro graphics. However after the upgrade to the GTX graphics, the noise from the case fans and the increase in idle speeds just drives me crazy (NOT THE GPU FANS THOUGH).

in your specific case for the z420 you should be on the latest bios (3.96) many people who run windows erroneously think that using a early bios will make the system faster as the spectre and other security patches are not loaded in the bios.

what they fail to realize is that windows will detect the missing bios patches and then dl the microsoft version of these patches which do exactly the same thing 

once the bios is updated,  try contacting the video card maker and see what they say are any other cards installed in your z420?

there are no other people reporting issues with nvidia 1050 cards causing fan speed issues on a z420 or other makes/models of computers

Ok... i understand your point that bios version does not matter. However, looking into the bios change log, i saw this:

"Version 3.50

Added support for latest Intel processors.

Added optmized fan support for latest graphic cards"

Pay attention to the " optmized fan support for latest graphic cards". this looks like that HP actually optimizes fan speeds for specific graphics cards. However, it looks like my graphics card apparently, according to DGrooves, that the others do not have any fan speed problems, so it looks like my one has problems. 

I will contact ASUS and see what they say. Also, i have no other expansion cards, just the TUF 1650s that I mentioned.

Other useful information:

- I use the stock 600w Power supply. looks like the new gpu needs a 400w which is met.

- nothing was modified, other than just upgrading to a SSD and also changing to the Asus TUF mentioned above which caused the problem

I will upgrade bios to latest version now

bios version DOES MATTER!!!! this is why i stated you should be on the latest bios, go back and carefully reread what i wrote
