Throttling the CPU reduces its power consumption.
Throttling the CPU reduces its power consumption.
I’ve been keeping an eye on my system and observed some intriguing patterns around CPU throttling. Whenever my CPU begins throttling—because of heat or power constraints—I notice a significant drop in reported CPU package power and a reduction in clock speed from 5GHZ to around 3.9GHZ or lower over time during the Cinebench multicore test. This made me question whether throttling directly lowers power consumption or if the decrease is mainly due to slower speeds or voltage adjustments. To give you a clearer picture, I’m running an i9-12900k on a Maximize Z690 hero with a 1000W PSU and an AIO Cooler Kooler 360mm cooling solution. I’ve been testing under workloads like Cinebench R23, and here’s what I saw: my score came in at 21,569 points, which is much lower than the ~27,000 points others achieved. During thermal throttling, power fell to 153W and clock speed dropped to 3.9GHz instead of the full 5GHz.
As the clock speed decreases, the CPU requires lower voltage, which results in reduced energy consumption. This energy-saving aspect is the main reason behind thermal throttling, since lower power consumption leads to decreased heat generation.
Yes, but the 360 AIO only handles about 150W of power. Make sure it’s installed properly and functioning as intended.
Despite working on renders or intensive tasks, the CPU keeps slowing down. Is this an AIO problem? Which one would suit these specifications best? I’m using a Cougar Helo 360mm AIO. I’ve seen it struggle with pump fan failure during heavy loads and only functions when I power up after temperatures drop. My aim is to avoid thermal throttling and maximize CPU performance.
