Experiment - what happens if you start the Ryzen 3 4300U processor without cooling (video)


One of the most pressing issues forprocessor developers is the efficient removal of heat generated during the operation of the chip. For this, passive and active cooling systems are used, as well as the release of thermal energy by the processor is reduced. An enthusiast nicknamed FritzchensFritz, using a thermal imager, examined the operation of the Ryzen 3 4300U processor on the Zen 2 architecture in extreme conditions of complete shutdown of heat removal systems.

It was found that the processor maintains good performance even without the use of any cooling, including passive cooling.

During the experiment, the Ryzen 3 4300U was justexposed to the open air. The processor has 4 cores that do not support hyper-threading technology, as well as an integrated Radeon Vega 5 GPU.


During the tests, the thermal chamber detectedthat only one of the two CCX (processor core groups) was active. At the same time, the enthusiast found out that the processor not only starts, but also shows stable results when starting the Crysis shooter during a 10-minute experiment. Cinebench R15 and 3DMark TimeSpy benchmark ratings were also received. For a single and multi-threaded Cinebench test, the processor received 124 and 327 points. The same processor with the cooler turned on gives out 140 and 550 points in the test.
