So here's the deal.
I own a HP Z820, specced as follows:
2x E5-2960 v1, 2.90ghz - 3.8ghz turbo.
96GB DDR3 12800 RDIMM memory.
GTX 1080.
Current Firmware/BIOS updates.
I love this box, but the over engineered fan header leaves something to be desired for the cooling in the environment that i am working in. I never get to 3.2ghz Turbo let alone 3.8ghz... The fans don't have enough umffff to cool the system appropriately under high loads and the chips are reaching TCASE way before they get to the theoratical 3.8ghz upper limit of the turbo of this processor. Which is funny because ive heard the fans rev actively during boot, but they never rev that high under full operational load... Not even close.
In short, I want to liquid cool my box, and my biggest challenge is to figure out how disable the silly fan header on the mobo so i can rip out the giant fan manifold and leave that space free for tubing and blocks. Just for reference, HP employees, your liquid cooling solution for the Z820 is a joke... IF that 6 fan manfold is still there, i consider it a failure...
I want two water blocks that lead to a radiator i can mount on the rear or even the top of the machine... I'm giving the BMW, a hood scoop, as it were.
Does anyone know or is there a diagram as to how that receptacle where the fan header plugs in is wired?
What signal is required back to the mobo for it to think its there?
Can i just bridge two of the wires so it delivers a tach back to the mobo?
Which ones do i bridge?
I'd experiment but im pretty sure there's a good chance of shorting it out and releasing the magic smoke....
Im hoping with a semi quick pump and some good fluid I can keep the chips cooler better in order to prolong the amount of time they spend at turbo frequency and below their theoretical max temperature... These chips are routinely sitting in the 70's to 80's when almost at stock frequencies at full load let alone turbo boosted....
Any assistance anyone can point out would be appreciated.
Thanks,
