[Solved] Are These Temps Ok 4 AMD Athlon II X4 640 Propus 3.0ghz?

It is NOT HIGH. What are you basing that on? I don't even know the CPU but I can tell you it's in tolerance for ANY CPU I've ever seen.

Having said that, you may not need to overclock the CPU. Since I know nothing about your system specs I can only tell you how to determine if overclocking is needed.

1. CTRL-ALT-DEL (opens taskmanager)
2. Change settings to show all cores/threads
3. change settings to LOWEST update speed for CPU monitoring
4. Run a game for at least 5 minutes
5. Close the game
6. Observe the CPU history graphs

This gets a little tricky, but:
1. If you had a SINGLE CORE CPU and it never hit 100% then increasing it's speed would make no difference to the game
2. If you have MULTIPLE CORES, but none of the cores hit 100% then increasing the cpu speed would still make NO DIFFERENCE to the game
3. If you have multiple cores but one of the cores hits 100% you MAY see an increase in a game by overclocking but it depends whether another core picks up the slack.

Most "gaming" systems are limited by the graphics and the CPU's aren't stressed to 100%. In such cases, overclocking the CPU makes zero difference in performance; it only increases slightly the noise and heat and at worst may crash your system. Modern CPU's are hard to destroy as they can shut down if the temperature is too high. (actually the "worst" thing is probably a CPU that is slightly glitchy due to overclocking. It's possible to have a CPU or RAM which is on the verge of crashing but instead they occasionally just change the information causing instabilities).

Summary:
1. Temperatures are fine
2. Quality, larger Heatsink/Fan can significantly reduce NOISE over the stock and is always more stable
3. CPU overclocking is NOT recommended unless you need it.
4. Task Manager can be used to monitor if you would benefit from the CPU being overclocked.
