Warranty Screwed Me Over

[Ty321]

I have an HP G9 Z2 Workstation. I’m having cooling issues with my CPU peaking 100c. Yes I still have a few months warranty left but HP is trying everything to not send me a replacement cpu and they know it’s the issue. Anyone got a solution? 

[DGroves]

this is a user to user forum, as such almost all posts are from users like you

and as we do not work for HP there's not much we can do

if HP was sure the warranty related issue was cpu related

then they would send one.

in my years in this field i personally have only seen one defective cpu

(and that one only failed on a specific instruction!)

it's most common for a external reason to cause a cpu to overheat

such as poor cpu cooling (bad cooler, poor airflow etc)

or a bad application trying to read the cpu's t-junction or t-case temp

and applying the wrong parameters resulting in a incorrect reading

i've also seen people "stress testing"  a cpu

using various 3rd party apps and claiming the cpu fails the test.

so while you might very well have a issue,....

your current post provides no basis for your claim that

it's  obvious to you that HP should know it's got to be the cpu

if you could please post a brief description of the problem

and how you came to determine the root cause is the cpu itself

this will help you possibly get a acceptable solution from HP

I ran diagnostic tests and submitted. I was monitoring the temperature during hps system check and the cpu got 100c and didn’t drop at all. I provided proof that it overheats and they still reject my request even tho they said I need a new cpu fan. I also ran full diagnostics and submitted to them!

again,..............which test? a HP one? if so which build? which cpu is in your system? which part of the test causes the temp spike?

as i previously pointed out non specific postinggs saying it doesn't work are not posts that can be used to provide help

and as i pointed out in my previous post a stress test is designed to force the cpu into generating the max load and temp by design if it didn't then it's not a stress test!!

during a stress test it's normal for a cpu to hit very high temps and possibly start throttling, this does not indicate a defective cpu

a stress test is not a normal cpu load, and should not be used to claim a cpu is defective because it forced the cpu into a unnatural state that caused high temps by design

I used intel xtu and cpu-z and hps imagediag reached 100c in a second. Yes I did send them the results. I have a i9-13900k and a rtx 5000 ada.

Above in one of your posts you stated:

"I provided proof that it overheats and they still reject my request even tho they said I need a new cpu fan."

That is one of the things DGroves also mentioned. I'd start there. It is quite easy to replace a failing CPU cooling fan. Did you do that?

I note that your current processor (i9-13900K) can run quite hot. It is listed in the latest QuickSpecs for your workstation, attached below from January 2025, but was that your original processor? The Intel specs for it shows it has a maximum turbo power of 253W... might you be running a processor your workstation was not originally designed to be running? Have you been overclocking it with XTU (which can run it up over 300W)? Is your Z2 G9 the Tower version?

and a google search of  "i9 13900 stress test"

most posts show that when stress testing this cpu hitting 100c  is common and within expected behavior per the published intel specs

Thing is, it gets 100c during benchmarks and also during gaming which is not ok! 

[DGroves]

again high cpu temps are almost never due to the cpu being defective

as i stated 100c during a stress test benchmark is normal, and since i don't

know which game and what options are enabled in the game/OS i can't say if the 

game is contributing to the thermals

check the case/cpu cooling fans, air intake/outake bad cpu to cpu cooler mounting

any overclocking to the system will also cause thermal problems same for changing the

default factory heatsink to something else

I would undervolt it but hp locked it on their motherboard it seems.
