Nice product, happy with my purchase and may buy again.

I set the maximum multiplier to 45 (I didn’t set it higher so that there was easy overclocking in 24/7 mode), synchronous for all cores, switches depending on the load. The heating of the cores is highly dependent on the current frequency and type of load. In multimedia tasks, the cores do not warm up above 40 degrees, at idle it is about 33. When encoding and compiling video, if the CPU usage approaches 100%, then the temperature slightly exceeds 90 degrees. After removing the load, the cores cool down in a matter of seconds. In stress tests at the same frequency, the temperature approaches 100 degrees, but does not reach this mark.

Pros

+ Performance. Video encoding with Xilisoft is 44% faster than the i5-4670K when both are in stock mode. + Automatic frequency switching depending on the load does not interfere with the operation of programs, saves electricity and reduces heat

Cons

- Poor thermal interface under the lid. When overclocked to 4.5 GHz and running tests in LinX, the cores heat up to 95 - 98 degrees, a little short of turning on throttling - After the jump in the exchange rate, the price became unbearable, but I managed to buy this percentage when it cost less than 20 thousand.
