Recently had a bit of an issue with a Z2 G4 - every time it boots, it gives me error 901, relating to a front chassis fan not being plugged in or malfunctioning. This is true, as the machine did not ship with a front chassis fan. Is there anything I can do to disable this error or remedy it, without doing the obvious of installing a fan?

did you add ram or a any other hardware? i'm taking a guess that since you mention the front fan you have the tower version and not the SFF model some of the hp workstations will trigger this message if you add hardware or change installed hardware such as a video card to a different higher wattage card
did you change any bios settings?

ahhhhhh,....as i thought!! the workstation monitors the temperature in several zones using onboard sensors and adding a video card can raise the temps to where the sensor kicks a alert
to test this theory, remove the card and install the original video card and if no change in fan msg double check that you have not moved a existing cable/connector to where it possibly is not making a good connection

lets see you have a computer that costs over 1000.00 and a video card that costs over 500.00 and you don't want to protect that investment with the less than 40.00 HP front fan kit
feel free to ignore the fan warning,........ it's not like HP thinks something bad will happen, they obviously just want to make 40.00 more dollars (NOT!!!)
common,....your specing out a cad system to hopefully make money not crash due to poor thermals....order the fan kit

I can sense some salt in that reply, so I'll ignore it and give you this;
If it's a £1000 system, surely it should come with an extra fan, in order to elude this issue, and not just be an extra £40 in the pocket of HP for no reason other than sales :^)
We've got customers who use these PC's for huge 3D CAD drawings and they dont crash due to poor thermals, because they're power efficient machines. It doesn't come down to a matter of overheating when they crash, because they don't heat up.

as to you comment that the system should come with all options (to suite you) as a stock item, i and all of the other uses who spec out a system (that meets our need not yours) which does not require the fan kit (or any other options) would rather not pay for things we don't need
Business that i have worked for usually value a stable system that makes them money vs a system that crashes at random and loses money....... my recommendation to you is the same as before, treat you customers right,... order the fan kit since HP thinks it's necessary with your specific build. In the long run you and your customer will benefit from selling a system configuration that HP does recommend and warranty vs one that is not a recommended HP configuration

A Z2 G4 model supplied by HP with a P4000 would have come with a front fan. P2000 would not. If the unit was supplied that way, it was a problem created by the seller.
Did they supply a unit without GPU and then supply a GPU as a separate item? Was it a lesser unit upgraded with a more powerful GPU?
The same situation exists with the Z4 G4.
