Threadripper 1950X very high temps on good water cooling?

[marivesel]

Hello to all, this is my first post here (found it as the best forum on google).

I'm having temperature problems with my setup:
Motherboard MSI X399 Gaming Pro Carbon AC
CPU AMD Ryzen Threadripper 1950X
Water Block: Watercool HEATKILLER® IV PRO for Threadripper™ PURE COPPER
EK Water Blocks EK-XRES 140 Revo D5 PWM RBG (Incl. Sleeved Pump) Reservoir Pump Combo
3x radiators (2x360mm+1x240mm) EK CoolStream SE Slim Premium Copper & Brass Core

There are no air bubbles, everything spinning at max (manually set), the water, radiators and cpu block are cold to the touch with my finger (should be below 26C), never heats up.
But my CPU temperatures go crazy with OCCT with CPU clocked to 3.8GHz 1.25V, temps go exponentionally to 85C for around 5-6 minutes and program stops (set to stop at 85C). The CPU Package goes above 104C (???).

Before the new setup the CPU was working on Air (Noctua NH9... the 2x92mm model). With the same overclock it was stable below 80C.

Any suggestions?
I was thinking that I haven not applied the thermal paste correctly, but tried 3 times - more paste (on both cpu and water block), then as little as I could apply (1 little drop, spread on the cpu only), it's always the same. Thermal paste is Noctua NT-H1.

Please for your help guys, what could be wrong?

Is there anything preventing the block from making proper contact with the ihs.

Something around the cpu perhaps or the cpu retention mechanism?

Did you connect the CPU block as per the instructions provided? Get all 4 screws started, then after that screw then down in order to apply correct pressure? Just a thought as I installed the same block yesterday (though mines the full nickel version) The builds not yet finished so I can't be certain if mines running cool or not yet, plus I'm running a 1920X

I don't think so, first time installing the water block I've applied thermal paste on the center of the CPU and the spread it with the water block by twisting and moving around, it's making contact on every spot.
But there is a chance that the contact is not the best, maybe the IHS holder (metal around the cpu, seems the same height) can be pushing a little bit, how could I find that out?

Installed several times with different orders, I don't think it's that much important... the screws go till the end.

So I have installed back the Air cooler Noctua, the radiator do gets hot (there is heat transfer) and CPUTIN temperature seems more stable at the same clock. But the "Package" CPU goes above 113C ??? What is this temperature, should I be worried?

Seems like defective CPU water block to me, should I ask for return and exchange?

What dies everything idle at? FX series AMD chips/boards often had temperature readout bugs. If it's starting at 59 and going to 110, maybe it's a hardware bug?

Possibly but sounds more like poor/no flow to me - no? I would say potentially something is blocking flow like jet plate in wrong, blockage in the block.

You find that the fluid temp will raise rapidly to what you are describing if there is a back flow causing the effect of static liquid due to some restriction. The ‘package’ is the CPU package I.e not a specific core it’s a generalist temp of the whole unit, if it spikes over 100 I imagine heat is not being removed.

Only trouble checking is opening the block to be sure nothings impeding unless you are measuring flow? What I did with a similar issue recently is connect up the cpu block and test out the rig, small piddle came out the exit tube as it was full of crap.

My first guesses would be:

• Bad cpu mount (screws not screwed incrementally in star pattern, Mobo component fouling the block etc)
• Not enough thermal paste applied
• Particularly convex / concave CPU block / IHS
• Very bad airlocks in multiple radiators (I really don’t think it’s this)

What are GPU temperatures like?
