Yes, you typically need to apply thermal paste to the CPU for optimal heat dissipation.

I always make sure to spread it out just to be certain, but I noticed Linus just glued it on... a typical Canadian move, lol. Not sure if that’s the best approach for that. I also know you need to spread it out on a bare DIY, though I’m not sure about using it for a CPU.
A typical placement or small pea-sized amount in the middle of the CPU works well. Specific patterns matter when adapting for models like Threadripper or LGA 3647, but for regular consumer chips without large IHS it’s not crucial. Even in bare die setups, you don’t have to spread it manually if the amount is sufficient. It’s usually recommended for consistency, though using the EK method (which appears in their GPU water block guides) is considered best practice.
On older Intel boards I trace a path through the cores, mount the cooler and spin it up before applying pressure. On AM4 I use a spatula to spread it out.
I measure the pea size at the center and place my cooler on it. I'll wait five minutes, then remove the cooler to inspect the coverage. If satisfied, I'll reattach it with a bit more and repeat the process.
TIM will activate once the cooler is positioned or latched, but it will also expand more when the system operates. You don’t need to take it out and reattach—it could cause overuse if you adjust later, which is inefficient. The best approach is to install it, secure the cooler, and verify temperatures while the system is running, not idle. If you notice temperature issues, you’ll be able to address them effectively. Also, it’s normal for temperatures to stabilize a bit after a week of use.
Completed a pea blob on a 7950x and it’s functioning properly. Performance is normal, clocks remain stable.
This approach works well for me, though it's specific to my situation. Not every reader has the same experience you've gained over time, which means they might not get the precise amount needed each time. I've spent more than 20 years handling various substances, from stock air to Ln2, and I understand how TIM behaves depending on the application. I don't see the point in changing it every six months unless absolutely necessary. Your money and effort are yours, not mine. I just know TIM stays effective for years after proper use, and I only reapply it when my actions require it.
