A:Answer Hi Peter, the Intel - Core i9-10900K out of the box is a 125 watt processor which runs at 3.7 Ghz with a max turbo boost of 5.3Ghz without overclocking. If you are worried about thermals you can always download the free Intel Extreme Tuning utility which has built-in temperature monitoring systems and will alert you when critical levels are reached, and when safeguards are activated.
Alternatively you could also look at the locked version the Intel Core I9-10900 which is a 65 watt processor with a base clock speed of 2.8 Ghz and max turbo boost of 5.2 Ghz. https://www.bestbuy.com/site/intel-core-i9-10900-10th-generation-10-core-20-thread-2-8-ghz-5-2-ghz-turbo-socket-lga1200-locked-desktop-processor/6411491.p?skuId=6411491
