high temps with 3 rads!

[FUSER]

 

can someone explain what's going on please? why so high temps on cpu package at low load (5%) and water temp only 30C ??

3 rad fans pushing air from outside in (rad receiving the hottest water) and 6 rad fans pushing from inside out

1 additional intake fan at the rear.

Pump running full speed and fans too (forced manually)

The only real active process is steam downloading and verifying a game.

 

Thanks

Bad mount, no tim, no water or severe lack of water flow.

What are load temps like under Cinebench R23 all-core after 10-15 minutes (it defaults to a 15 minute loop)?

Its a Very hot chip. Not sure what you expected any differently? 77C Under a fullload is amazing for a 13900k if you did not do any tuning. What were you expecting exactly? Its 250W on a chip that size, that much watercooling is designed for silence and performance, but you are asking a lot of it. It has to go through a IHS, that alone can take quite a bit of the temps, along with the proper design of the cooling plate, optimizing exactly where the 13900k die is and everything, its quite complicated. Overall, its doing its job just fine, your expectations are all out of wack. You want cooler thermals? Optimize the voltage curves and power, the frequency and then you will see a drastic thermal drop. The chip is doing its best to hit 5.8 ghz, or if its an allcore workload, usually whichever boost bin it sees fit with the thermals.

It has been overclocked with 6.1Ghz on 1 P-Core and rest p-cores around 5.6-5.8 Ghz.

 

Couldn't achieve anything more stable using ASUS AI overclocking. definitely thermal throttling as most P-Cores drop below 5.5 Ghz. Perhaps lowering voltage would fix this issue to an extent (any guide for Z790 mobo + i9-13900K for manual overclocking by any chance?)

 

Of note since i run 4 sticks of DDR5, I can only get 4800MT/s instead of 5200MT/s - not sure if this matters on the Cinebench score as much.

 

After cinebench testing looks like my watercooling system has quite of capacity and defies any issue with insufficient contact with the CPU.

 

Final Cinebench R23 score (15 minutes):  36,063 (multicore)

 

These are 7 minutes in Cinebench R23:

I haven't dug into the latest gen stuff as I don't own any of it, buuut I can tell you that ASUS AI Overclock loves dumping ungodly voltage into your chip in an attempt to make it stable, I would recommend disabling it and manually tuning. What voltages is it pushing vs stock, and if you revert to stock what do your temps look like?

 

Also, can you expand the "Core Temperatures" dropdown in HWiNFO64, that will let you see per-core temps. IIRC the mounting solution for 12th/13th gen flexes them enough to cause uneven contact (thus the aftermarket contact frames to apply even pressure). If you're seeing large differences between individual core temps when they're all under the same load and at the same boost clock/voltage, that could be a sign of it.
