I installed a liquid Z820, but I saw still; 528: CPU requires liquid cooling system. HP Z820

[dongmei]

Dear every one. 

I was using E5-2687Wv2 CPU on HP Z820 under a common(air) cooling system. I saw a warning; 528: CPU requires liquid cooling system.

So, I installed a cooling system. but I am seeing the same warning. Moreover, CPU fans rotate more fastly with great noise.

I can not run windows system because computer has a greater noise than air cooling. I turn off computer power. I am afraid to run windows systme. 

I want to know it is a normal or error??? 

Please help me.

Thank you.

the HP liquid cooling kit uses a 5 pin fan connector that connects to each cpu fan header on the z820 motherboard

failure to connect the HP liquid cooling pumps 5 pin connector to the motherboard's 5 pin header will cause overheating issues

3rd party cooling kits lack the correct 5 pin header, and unless modified, will not work correctly

Thank you for your information.

I am confused a little. https://h30434.www3.hp.com/t5/forums/replypage/board-id/Business-PC-Workstation-POS/message-id/26039

Please see 3:19. My installation is the same. Port is 4fins and wires are three.

Temperature is raised highly during just windows lunching. greater than 90C.

What do I have to do? Coller is wrong or installation is wrong?

Please kindly correct me.

Thank you.

I pulled a spare z820 motherboard and checked, the two water pump connections are 4 pin not 5 pin (my mistake) and are marked "LC0" and "LC1"  since we don't use water cooling, i have never seen the pump power connector, but must take your work that it's a 3 pin not 4 pin connection

with the water cooling installed, have you added the nessary fan to the cooling shroud when using dual cpu's? this fan sits in the shroud near the second cpu's ram bank

both cooling shrouds need to be installed main shroud that covers the cpu's and the one that covers the PCI-e card area

did the water cooling kit include thermal compound for the cpu's? and if so was it applied properly?

power on the system, enter the bios and check the system temps using the bios's thermal probe sensors to see what temps you are getting on the cpu's

Thank you for your comments. 

I have checked all connection wires in Google. All has 3 wires and is connected with LC0 and LC1. Cpu and Memory Fans are separately installed on the main board. They cover the CPU heatsink and Memories. 

And I could not enter the Bios because Fan sound was very large. I uninstalled one CPU(CPU1) and test only one CPU0, I ran temperatuer measurement program on windows 10 eventhough CPU fan sould is very large and saw a warning of "528: CPU requires liquid cooling system"  Temperature was over 90C. I initialized BIOS as default before I ran windows 10.

I guess that cooling pump did not work so that CPU heat can not threw via liquid cooling system.  And Thermal grease was good. Both Liquid cooling systems look a used goods.

I fianlly used the original air cooling system again, it was fine.

I am so confused now.

Is there any way to check liquid cooling system?

yes you can check the pump, by connecting a current meter inline with the +12v line

buy a normal 4/3 pin power extender off ebay

https://www.ebay.com/itm/5Pc-20cm-4-Pin-Molex-IDE-to-3-Pin-CPU-Fan-Power-Connector-Cable-Adapter-Fin...

connect a clamp type amp meter onto the extension cable and see if it's drawing current

or just power the pump from a ext 12v source and hold it to your ear and see if pump is running

just a thought, is the water pump connector a 4 pin header (with only 3 wires attached) or is it a 3 pin header?

if a 3 pin header are you connecting it to the correct 3 pins on the 4 pin MB header?

Dear I have checked cooling pump and workstation fin state.

pump is good, but power is not applyed from 4 fins.

How can I setup workstaion Z820 so that power is applied from 4 fins connector?

Thank you.

i can't answer why you do not have power on the LC0/LC1 headers

you can however grab power from a SATA or molex connector using a adapter  (SATA/Molex to 4 pin)  on ebay or amazon

you need to see if the liquid pump is using +5v/+12v  combined or just one voltage them

i checked the HP media services library and confirmed that LC0 is the correct header

Dear Thank you.

I fould the reason. Power was not supplied from the 4Pin connecter on the motherboard.

I don't know why power is not output from the two Liquid cooling 0 and 1 power connectors of Z820.

I think it is wrong motherboard itself.

Then did I buy a wrong workstation???

You need to get a new liquid cooler. i had same issue.
