HP Z440 Server temp memory fan bypass w/o getting the error at boot when all memory slots are full. 

Excellent stuff for us who took the hardware out of the z440 case and put it in a regular high airflow atx case, with 3x140mm fans. :)

GREAT TIP! I'm building a Z440 right now and having all kinds of CPU, Front LED/Power, system fan issues, but I'll go ahead and make your recommended pin jumpers because I have all 8 DIMMS populated with Kingston 32 gig ECC memory with NO mem fan shroud.

Thank you for your effort, you saved a day!

This will be great to use in a case swap and loading up all the udimm slots :)

Hi, thanks for great vídeo and working Doug.

I just found that for HP Z6 G4 the mem fan has 4 pins, which are: 1 for ground, 2 for 12V, 3 for RPM sense, and 4 for PWM control. Which pins should I put a jumper on in order to get rid of the 517 error? Thanks a lot! Your video is fabulous.

Fantastic tip. Just what I was looking for. Got hold of one of these last week. I can't populate all-the-slots. I have 8x *Gb sticks. 3 came with the workstation, and I bought 5 more. These work fine in any combination using 4 slots to the right of the CPU (from pov used in your video) and the left-most slot. If I put anything (even on its own) in any combination that includes the three slots immediately to the left of the CPU, I get a post error (beep and red flashing light). I am aware of the installation order, as shown on the inside of the cover. Whatever I put in those 3 slots causes a problem. All the memory sticks checked out and work alone and in combination with others (old and new). Have you seen this before?

I have one with E5 1620 V3 and 32 gb and a K2200 Quadro. Goes very well. I might throw a 1650 in it. Unfortunately it has the 500 watt PSU.

Thanks so much for sharing!

Thanks for watching your video. Is there any way to adjust the speed of the memory fan? I found that it still makes a lot of noise even when the temperature is not high.

I just ordered the fan and housing. It was like $30 on ebay

just what i needed. the memory cooling unit is 120 USD on ebay, and the message stops the boot on my hp z6 g4 workstation.

Thanks , you r Good

I just bought the stupid front fan kit, and I have a nVidia Tesla P4 installed (with its 3d printed fan shroud and that fan running off of SATA Power separately) and its still giving me the stupid front fan required in this configuration bios error. Does ANYONE know, or know where I can figure out how to disable this? Because I have the stupid fan and its STILL throwing it...

worked for 9 x HP Z440, for one it's not :( , bios and all the other drivers are up-to-date. i will need to figure out what the hell is going on.

Hi, I have a quick question this fix worked pretty awesome when I shutdown and turn on the PC, but the error still appears if I reboot the PC, can you help me please to confirm if you face the similar issue? I’m planning to buy the fan baffle and dissemble it because I’m not using the HP case, any advise is appreciated.

Hey. What's the type of the jumper you're using to bridge these pins?

Cool! But how did you find out that this is the way to do it? Just trying to learn something new...

does not work after reboot, unfortunately 😕

please show us front fan jumper connections bruh!

does that message that you need the shroud pop up at EVERY reboot? or just once? my guess is everytime, otherwise there would not need to be a workaround like you showed here. thanks!
