I want to overclock the CPU. CPUID Hardware monitor PRO tells me that running default my cpu maxes at 65 degrees Celcius when stress tested, so I think I will need to upgrade my cooling.
I am looking for reccomendations both for cooling and overclocking settings.
65C works well for load and stress testing temperatures. Maintaining below 80°C during stress tests indicates solid performance.

Hey! Do you have Intel XMP enabled in your BIOS? Then Intel XMP will provide a stable OC without worrying about temperature or other issues...
Stop this immediately. Do not continue promoting Overclocking posts about enabling XMP. XMP is unrelated to CPU overclocking tools. If you lack understanding of a subject, please stop responding.
The small 120 mm radiator/AIO units work adequately with the stock configuration, but expect limited headroom.
If your mainboard includes an MCE setting in its BIOS, you might try turning it on and observing clock speeds—ideally around 3.9 GHz for all-core when enabled, or 3.5 GHz for multi-core—and ensuring temperatures remain stable.
Through Intel's XTU interface, you can increase the all-core clock speed by up to 100 MHz; however, choosing a higher increment (such as near 4.5 GHz) could cause temperatures to climb too much, especially with your current cooling setup.
The GTX970 and 6600K are currently only capable of around 60 fps gaming, which is typical considering their age, architecture, and just four cores/threads.
It makes sense to invest in a new cooling solution for the older CPU, and consider pairing it with a 12600K mainboard and GPU together.
6600K is a solid option for overclocking.
To make it easier, begin slowly increasing the multiplier in the BIOS bit by bit. Leave everything else on auto.
Run Hwmonitor and then perform a load test.
Try the CPU-Z stress test.
Observe your performance.
85°C during testing is acceptable.
If you reach close to 100°C, that’s when the chip will start throttling or lower the multiplier to protect itself.
A core voltage around 1.30 should be your maximum safe limit.
Use speedstep or adaptive voltage control.
This will lower both voltage and multiplier when the chip is idle.
Don’t push too hard—every chip behaves differently.
Many users post high overclocks, but those with dog chips tend to stay quiet.
