HP Z820: Obtaining additional power for Graphics cards

Mon, 23 May 2022 10:10:35 -0700

I see that there is space for added graphics cards and appropriate slots. Is there some type of extra power cables near the graphics cards that would allow a GPU with added power requirement (6 or 8 pin power connector for card) to be added.

HP Z820: Why my fan speed and noise increse after win7 64 boots up?

Mon, 17 Jul 2017 15:46:21 -0700

Hello, i have bought a z820 workstation 15 days ago with liquid cooling system. On the first weeks when i was turning the power on everything was really quite and peaceful, no fan noise, (it was feeling like the workstation was off!)that's why i chose liquid cooling in the first place.

BUT:

My problem now(after 15 days) is that every time i turn on the computer the noise of the fans are really annoying and the noise is getting louder especially when windows loads!

I have updated the bios to the latest version(and set the fans to the lower spin setting), i have remove hard disks from the machine to minimize watt, i change the power option settings from high to low to super saver, i have clean the board with air/spray duster, i have remove the workstation to a bigger room without anything to block the air supply,i have even try to connect the power supply to a different socket but nothing has change! the noise is still there!

I do not know what is the problem, i was really happy in the first days, no sound, no fan spinning, nothing very very quite.

Please anybody with a solution!
