appropriate wait time for turning on your PC after applying thermal paste and mounting the cooler

After applying thermal paste and mounting the CPU cooler, it is generally recommended to wait around 10 to 15 minutes before turning on your PC. This waiting period allows the thermal paste to settle and form a proper bond between the CPU and the cooler. However, ensure that the cooler is securely mounted and all connections are properly seated before powering on the system.

No Curing or Setting Time is Required

It's important to note that there is no curing or setting time associated with thermal paste. The computer is usable immediately after application. The term 'curing' in the context of thermal paste refers to it hardening due to heat exposure, but this is not a concern in normal use. Thermal paste cures only if exposed to sufficient heat over a period of time, depending on the specific product.

Curing is not necessary and something I do not find beneficial. As your paste cures, it can become rigid, requiring reapplication periodically. This can be particularly problematic if you frequently remove the cooler. Uncured paste can be more easily removed without scraping.

Effective Application Methods

There are countless nerds who believe they have the 'best' application method, brand, or procedure for thermal paste. This often leads to passionate debates, but the truth is, any method that ensures an even distribution of paste across the IHS (Intelligent Heat Spreader) is effective. A decent quality diamond or Kryonaut paste is typically sufficient for most gamers.

The difference between lower-end and higher-end pastes is often negligible, usually within a range of 3 to 5 cents per tube. For the vast majority of users, including gamers, this minor difference does not make a significant difference in performance. If you find a significant difference, it's likely due to individual circumstances rather than the product's quality.

Mounting pressure is crucial. The pressure exerted by mounting the cooler is generally sufficient to spread the paste evenly. Assuming you're using decent paste, mounting pressure matters more than the method of application. Uneven mounting is typically the reason for hotspots and poor performance.

Quick Turn-On, No Waiting Required

Once you have applied the proper amount of thermal paste and ensured the CPU cooler is securely mounted, you are ready to use your computer. You do not need to wait any longer before turning it on. A proper application and even distribution of paste, followed by secure mounting, is all that is required.

In summary, a short wait time (10-15 minutes) is recommended to allow the thermal paste to settle, but the computer is fully usable immediately after application. Proper installation procedures and decent quality thermal paste are key to optimal cooling and performance.
