Checking power consumption helps determine how heat builds up during maximum use versus a less powerful CPU.

The Ryzen 2700x consumes 105 watts while the 3700x uses only 65 watts, suggesting the latter may run cooler. This implies you could potentially reduce or minimize concerns about CPU temperatures by opting for a lower-wattage processor. However, there might be other factors to consider. Regarding cores and threads, they are identical between the two models—so you’re not missing anything there.

CPU power is mostly turned into heat. A 60W processor generates half the warmth compared to a 120W one. The 3700x doesn’t waste 65 watts. At maximum demand without PBO it draws 90W and creates 90W of heat. The 2700x consumes 105W under full load, producing the same amount of heat. Efficiency matters—even a 100W CPU might need only 40W to match the performance of a 65W CPU running at full capacity.
Power usage merely shows what you need for cooling, not the chip's operating temperature. Today’s CPUs, particularly modern Ryzen models, usually have strong thermal resistance, meaning they might not draw much power yet still get quite hot. With heavy water cooling, an overclocked X58 i7 920 using 200W could stay between 60-70°C at most, whereas a 5950X under the same conditions would likely hover in the high 80s. Power ratings themselves are often misleading; many chips exceed those values and perform better under higher loads.
I understand your questions, but the decision between air and liquid cooling feels tricky for me too. My 2700x reaches 85°C in just two seconds during a Cine bench test—something I find hard to accept, especially when I think of lighter tasks like opening many tabs or spreadsheets. I’m using the Wraith Prism air cooler that came with the unit… it seems like my only clear choice is this one.
each processor's real power usage and tolerance vary. I believe the 2700x and 3700x models are closer to around 135 watts at stock settings. The 12600k stock runs about 210 watts thanks to its improved IHS, but adding 200 watts to a 2700x will cause overheating even with the same cooler. The 12900k draws roughly 300 watts, reflecting its enhanced power handling. If you push it to 100% loads—like Cinebench, Blender, or P95 non-FFT—those numbers are accurate. Be cautious; some programs can report up to 140%, especially with advanced drivers like Prime FFT or OCCT. TDP isn't useless, but actual power consumption is more realistic.
I reviewed the video shared by a user about Gamer's Nexus, noting that both AMD and INTEL appear to misrepresent their actual TDP values. It would be straightforward with proper testing and experts to compile accurate cooling requirements for each CPU model. If they didn’t, it could cost them customers who experience overheating issues. It seems like a deliberate tactic to boost profits without transparency. I believe the small gap left under the lid of these CPUs is intentional and potentially illegal. Someone should report this to the appropriate authorities. My frustration grows when companies hide such details and avoid accountability.
It doesn't require filling the space beneath the heat spreader. It merely needs to cover the area between the top of the die and the base of the heatspreader. This is exactly what it does. If not, there would be no thermal transfer path (and the heat spreader would detach immediately after cutting the adhesive).
