Removal, Liquid Metal, Sanding for i9 9900k
Removal, Liquid Metal, Sanding for i9 9900k
I've reviewed that video several times, and the temperature drop he shows is impressive (around 13-14°C). However, I'd be cautious if I were you. Especially since this is your initial build, it's wise to familiarize yourself with your CPU before attempting anything—are you aiming for OC competitions? That trick could be useful, but I managed to maintain temperatures between 66 and 72°C using a Noctua D15S cooler at 4.9 and lows in the 60s while working on videos. You don't have to rush into advanced settings; instead, look into what others have experienced when sanding their CPU's die.
Do you truly stand to benefit? Intel has also reverted to employing Solder Thermal Interface Material (STIM) in between the die and heat spreader for the i9.

Do you think you're really going to get anything?

No way I had any idea the i9 9900k used solder, that's why I was curious about the razor blade. Just kidding. I was aware the 9900k did use solder. And yes, if I follow the IHS, die sand, and add liquid metal, I'd see a big temperature drop.
I've reviewed that video several times, and indeed the temperature drop he shows is impressive (around 13-14°C). However, I'd be cautious if I were you. Particularly because this is your first build—get familiar with your CPU before attempting anything serious, especially if you're thinking about entering OC competitions. That technique could help, but I managed to maintain temperatures between 66 and 72°C using a Noctua D15S cooler at 4.9 and keeping the system in the 60s during video work. You don't have to rush into advanced settings right away; instead, look into what others have experienced when they clean their CPU dies.
I've tested two i9-9900K CPUs and two motherboards. The first motherboard caused both my CPU and itself to fail after installing a new BIOS release. After that, I found other users online who reported the same problem with the latest BIOS on the same board. The second motherboard likely had a faulty or defective BIOS chip, becoming increasingly corrupted over time. I was able to obtain Return Merchandise Authorizations for both CPUs and the motherboards.
If you ever reach temperatures above 5.0°C during OC attempts and can't manage them, you might consider trying it, but I'd definitely check online discussions after removing and cleaning the CPU dies. Just 02 from an old fart
