high temps

[sharp sphinx]

i'm gonna became crazy with this AIO...
Anyone here tested the Z73 Kraken on any LGA1851 CPU?
i'm reaching 100ºC temps lmao
atp i'm suspecting a pump issue
or bad hotspot location compared to AIO pump

CPU: 270K Plus > No OC
MBO: MSI Pro Z890-A
Cooler: NZXT Kraken Z73 360mm with LGA 1700 bracket

I repasted recently and fixed the pump speed, but... there's no change at all
The temps are reached after 5 minutes on AIDA64 stress test. Room temp about 25-26ºC
Amy one knows if this is normal or something?
or even if is the bracket not working as expected?

[mental lichen]

maybe the bracket isnt letting the cooler fully touch the cpu? lga 1700 vs lga 1851.. i dont have an aio so idk if the aio pump would make any noise under load

Is the plastic sheet removed from the cold-plate ?

[sharp sphinx]

There’s not plastic cover in the cold plate

It was a big piece of plastic covering the preapplied thermal paste

[sharp sphinx]

Maybe a contact frame can help to fix this?

[wild wave]

I've found many of these when I've helped people with cooling issues. One in the last two weeks. 🤖

They were trying to under-volt to manage thermals

I asked them to check for the plastic sheet

it was there

18 months of overheating problems gone

So. . . I had to ask

[sharp sphinx]

Hahaha yes I’m very aware of that type of mistake

But I can confirm that there’s not plastic cover

Since the pump came with pre applied thermal paste

[wild wave]

There must be a problem somewhere

The pump is definitely pumpung?

[sharp sphinx]

I think I’m gonna test with another cooler, I suspect the pump is not doing good contact with the CPU

[sharp sphinx]

I was suspecting that it would be clogged but…

[wild wave]

Air lock ?

[sharp sphinx]

Air lock?

[wild wave]

Radiator above the CPU?

The pump can't pump air, so if an air pocket gets to the pump, it stops pumping

[sharp sphinx]

Ah I get it. I think shaking the pump can help with that, right?

[wild wave]

Maybe power the pump and give it a wiggle. any air should end up at the highest point

How quickly does the temperature get to 100c ?

[sharp sphinx]

After 2-3 minutes

[wild wave]

360mm and the fans are turning?

[sharp sphinx]

Yes

Everything working and no strange sound

[wild wave]

What power is the CPU using?

[sharp sphinx]

250w, the stock configuration for 270K

…perhaps the pump is unable to manage the heat?

This AIO is 4-5 years old

[wild wave]

That AIO should be good for 250W I'm sure of it

Have you been using it for 4-5 y ?

[sharp sphinx]

daily, yeah

[wild wave]

This is a new CPU MB build for it ?

Looking at reviews, I see some NZXT software. Does that show pump speed and fan speed OK for you ?

[sharp sphinx]

There's no reading issue as far i know

not in this case

[sharp sphinx]

For AIO? yeah. I guess?

[wild wave]

Maybe pump to 100% to see if it helps?

It looks like it is doing the things

Does the liquid temperature get high too when CPU is at 100c ?

[sharp sphinx]

i never saw it past 40ºC

[sharp sphinx]

Ok. On it

[wild wave]

I've seen tear downs of used AIO cold-plates and some do have gunk build up which restricts the coolant flow over the cold-plates fins.

Is it still under warranty?

[sharp sphinx]

i think so

i need to check on NZXT page

after repasting and cheking the mount bracket again

[wild wave]

I'll look for some reviews of it too

Does the mounting pressure seem OK ?

[sharp sphinx]

No, is a little weak

and i think is because the mount is not well made

or something

20 minutes on OCCT Linkpack, a very demanding test

At the least is not 100ºC at the moment, like AIDA

[wild wave]

Might be able to increase the mounting pressure with some shorter stand-offs or washers somewhere

[sharp sphinx]

uh

that would mean dismount all mobo?

hmm

let me check tomorrow when i have the new cooler to test

[wild wave]

This should be accessible without taking the board out.

The case should have a cut-out for access.

[sharp sphinx]

not this case

The space in the back is covered by the PSU

(MSI MAG PANO 100L PZ for reference)

i end up buying the ARCTIC Freezer III Pro 360

i mean, dismount the PSU is easier than the mobo

[wild wave]

Hopefully all the issues go away 🤖

[sharp sphinx]

also i will check this out

because the pressure was bad

and i bet this has the fault

[wild wave]

This happens a lot to me. I have had to modify (FAFO) water cooling set ups more times than I should have needed to. I have saved a lot of spare parts that come in handy.

[sharp sphinx]

Seems like the bracket was not enough

Photo not related

So

The included bracket was absolute trash because there was not enough mount pressure

[sharp sphinx]

AIDA64

so good so far

with new AIO

So… yeah

The old AIO was not enough this time

I swear, changing the whole mounting is a nightmare

But I can confirm is basically fixed now

[sharp sphinx]

thanks for the help @wild wave
