Is this a good CPU Thermal Paste?

Solution
The thermal paste should be fine. If temps are a concern you need to consider the ambient temps in the room where your pc is located, overall airflow in your pc case (is it adequate?) and the cooler itself. Thermal paste accounts for very little in terms of performance from one brand to another. Maybe 1-3c difference among most common thermal pastes.

If you're looking for a 10, 15 or 20c difference it won't matter which paste you use. The only way to really lower temps is a better cpu cooler, lower ambient room temps (if they're around 30c or higher try a fan or air conditioner to lower room temps) or both.

Depending on your cpu it may be hard to accurately measure idle temps. It also needs to be true idle, not 15% cpu load or 20%...

Depending on your cpu it may be hard to accurately measure idle temps. It also needs to be true idle, not 15% cpu load or 20% load, 0 is idle and it needs to stay that way for around 15-20min to get an accurate assessment (or as close to 0% as possible, windows itself may cause the cpu to go to 1-2% briefly). Idle temps themselves aren't as important as temps under full load which is when a cpu could potentially suffer from overheating.
