Jesu li vodena hlađenja za starije sockete kompatibilna s ovim?

Kompatibilni su uz LGA-1700 mounting kit, ali nažalost dosta tih starijih AiO rješenja na nasjeda kak spada, jer Alder Lake ima niži IHS, pa sve skupa na kraju ne paše 100% i temperature su onda na sve strane.

Intel Core i9-12900K at 125W: What happens when power is dialled down?

Citiraj:

Installing a 125W budget reduces the all-core-load power consumption by well over 100W when evaluated as a system. It’s rare that desktop machines run on a 24/7 basis with such a load, but if that is the case, and you can accept the 10-15 per cent lower performance. The under-load figure drops from 73°C to just 54°C. Running at the same temperature, however, enables us to reduce the cooler’s fan noise by 6dB. Sure, you sacrifice some long-term oomph, yet we feel it’s a price worth paying for those who cherish quiet computing. We’ve spoken at some length about the more efficient V/F curve at the lower end of the scale.

There’s further proof in the energy-efficient chart, where system-wide power consumption is considered against the all-core Cinebench score. Going up by 33 per cent is no mean feat, of course, but AMD is still better in this regard. Limiting power is most keenly felt in tasks such as rendering. In these cases, performance drops by no more than 15 per cent, which puts the Core i9-12900K neatly between rival Ryzen 9 3900XT and 5950X in many cases. This indirectly tells us AMD’s process and architecture implementation remains excellent; there’s no need for AMD to panic as it remains attractive on performance as well as power.
