HP Z2 G9 i9 14900 CPU cooler upgrade

[Tomchoww]

I need to upgrade the CPU cooler on HP Z2 G9.

At 35% cpu usage the tempeture spikes already in 90 celcius.

at 100% CPU usage the CPU pass 100 celcius and more... probably throttles down to save itself from criticla failure.

It comes with a tiny 65 W cpu cooler that can barely control the immense heat dissipation from this i9 14900.

Unfortunitly HP are so effcient in their calculation IntelCPU states TDP 65% so of course use the smallest CPU cooler in their inventory... in this case a tiny cooler that sends heat to the motherboard.

anyways I ll give advice to HP for its miscalculation in  in computer design another day when someone will pay me for it.

FOR NOW, can you please me explain how to fit an Noctua CPU cooler that has 4 pin plug into the 5 pin CPU fan connectoir plug that comes on HP motherboards.

I will also gladly buy an high performence CPU cooler made by HP if HP will sell it to me to retrofit This HP Z2 G9 I have.

Thanks,

I found this thread as I'm having a similar issue with my i7-equipped Z2 G9. I added a 4070 ti super card for GPU acceleration of AI tasks. My fans started going into overdrive so I checked the CPU temp and was seeing 80 degree averages with spikes in the 90 degree range. My GPU is staying close to 50 degrees.

Per Intel's spec sheet, the Tjunction on my CPU is 100 degrees, so being 20 degrees under that should be fine but I'd still like to play it safe if there are some easy fixes. I'm going to try adding some more fans to the upper section of the case first to see if that changes anything. After that I'll look at changing the CPU cooler as well and suspect I'll have the exact same question as you.

For what it's worth, I bought the MSI Gaming RTX 4070 TI Super 16G Expert as the nvidia drivers let you select gaming or AI workloads. I did need to buy a right-angle power socket adapter and remove the metal cross-brace to get it to fit into the Z2 case. Three reasons I bought this card in particular:

1. It was the most powerful 40X0 Super series GPU that had a 700W minimum PSU requirement (I don't want to upgrade the PU to a non-HP unit)

2. Its length fits into the Z2 G9 (some of the longer cards won't fit)

3. It has direct to exterior fans/cooling with its three-space design (so it doesn't just blow hot air around the case)
