Normal or poor thermal interface?

[r00tb33r]

i9-11900KF and FC140, with TF7 in between.

 

When I run Cinebench the core and package temperature instantly shoots up into high 80s, like 86°C and beyond.  Is that normal or an indication of poor thermal interface? (Such as crooked IHS, uneven cooler pressure, too much paste, etc.)

It's fine, temps react immediately to load changes.

I solved the problem by getting rid of the heat source

Could be a thick application of TF7. You want to go on nice and thin. Some TIMS act as an insulator if there is too much.

Yeah, I do admit to that.  I was excited, but I do know better.

 

That's been on my mind the whole time.  But the stuff is also kind of thick which actually contributed to the heavy application.

Since I moved to AM4, I have been applying my TIM differently, compared to when I was on Intel.

 

On Intel, I would draw a line down the center of the cores, plant the cooler, and give it a titty twister before clamping it down.

 

Now I draw a thin line on the edge of the CPU, and pull it across the IHS moving in straight lines. Usually 3 pulls per direction. I will clean the spatula off if there is excess material, and keep pulling. Once I have my TIM down, I let it set for 10-15 before I install the cooler. Works great 

 

I am using SYY-157
