Something I don't understand - CPUs

[d3one]

My previous processor consumed 77W on load and the temps was 60-70 Celsius, now my currect cpu 9900k consume 200w on load with temps of 80 degress Celsius. 

If I understand that right, for lower power consumption I need to get a better cooler. Is that right?

If anything, power consumption may go up with a better cooler.

If temps are lower it could lead to less thermal throttling and higher (or more prolonged) boosting of clock speeds which could draw more power.

If the goal is to cut power consumption then drop your CPU clock speeds and voltage.

speed + cores = power (kinda)

 

faster cpu with more cores = more processing = more power

Just because your CPU consumes more wattage doesn't mean that it'll get hotter. Sure some of the eletricity will be lost to heat but most of it will be used to power the different transistors and stuff

higher power the more heat you need to dissipate. which equals the need for a better cooler. 

 

also the 9900k doesnt allways consumer 200 watts. just in almost every mobo because they break spec. 

 

then there is also the ihs (Integrated Heatspreader) which is the metal plate between the chip and cooler. 

 

the thermal compound between the ihs and CPU does have an effect on the heat dissipation

Depending on what your 77W cpu was the size of the die changes the temperatures for example 45nm is hotter than 32nm yet a 32nm chip may use more watts

The better you can cool your processor the less electricity it will require to maintain higher clocks what makes it run colder as a whole.

Laws of physics that is correct

Lower temperature has NOTHING to do with lower power consumption as far as I know. Power consumption all depends on load regardless of temperature. So even if you poured Liquid Nitrogen, and you lowered your CPU to a near freezing temp, you would still need the same amount of voltage to achieve the same overclock.

 

However, your CPU will fail to overclock to a certain degree if you do not have sufficient cooling.

1) low temp (CPU cooler) + 2) CPU's ability to withstand voltage (depends on the silicon lottery, not all CPU can overclock the same even if they are the exact same chips) +3) applied voltage ---> overclock
