Thermal Paste being pushed away from Centre of CPU

Hello everyone,

Built a new PC not long ago. having Temp/stability issues.

I have a i9 14900kf with a Noctua NH-D15S, I understand that the noctua cooler is not quite up to taming the temps of the i9 however I have had to reapply thermal paste like 3 times now and everytime this is what happens. This causes a lot of my games to crash as the CPU isn't getting a stable temp control. I have followed all instructions in the cooler does any one have any ideas on what is causing this or any steps I should take to stop this from happening? When I reapply the thermal paste it runs like a dream for a day or 2 then the crashes start happening again.

 

Thanks

Kinda "known issue" with LGA1700. That 2-point retention mechanism bends the heatspreader so it's not flat and contact isn't great.

One of 2 things are happening I feel.

 

1: both cooler and CPU IHS are convex, meaning they have a small mount in the middle and slope to the sides causing this

 

or

 

2: the tension from the ILM locking mechanism is causing a weird flex. This was a problem with 12th gen CPUs when the 1700 socket was first launched, but this would be the first I've seen or heard of it since if it were it.

I believe the other folks are wrong about the bending. The ILM bending would result in the opposite shape,  a lot of paste in the middle.

Edit : or maybe not, maybe the shape is indeed concave but empty (of paste)

When you show the residual paste, I'd also like to see the pattern on the cooler. There are two sides to that story.

You could try another thermal paste. Which one you've got ?

Of course you could still try the contact frame, I have one.

The bending makes the sides lower, so the only part that touches is the middle, so the paste gets displaced from there and squeezed out the sides

I thought the bending made the whole middle part lower. That's what I seemed to get.

And even touching in the middle doesn't sound so bad for thermal contact.

My paste here Arctic MX6 seems more "dry" than yours, maybe better ?

Can't press the sides down and have that result in them being higher...

Mine was also empty at the center

But you can press the sides down and have top and bottom being higher

@Churrie

What thermal paste are you using? Some popular pastes can quickly fail. Try using Honeywell PTM 7950.

Im using Noctua NT-H1, have thermal grizzly cryonaught on the way, thermal paste is new as I have to replace it for the same issue after like 2 days. the thermal paste on the cooler is showing the same thing, none in the centre and has all been pushed to the sides

For information, this is now an older video. Right from the start Steve shows measurements of weak pressure in the middle.

I just checked, it's also in the video you posted.
