In this paper, the Cattaneo–Christov heat flux relocation paradox on Casson fluid with MHD and dissipative effects was considered. The buoyancy and heat generation effects were believed to be responsible for the natural convection, while variable properties were perceived as temperature-dependent linear function. Under the given assumptions, the governing system of equations was formulated and transformed. Hence, the Chebyshev collocation spectral approach was therefore employed to achieve an approximate solution. However, the behaviour of temperature-dependent variability establishes the relationship between the boundary layer flow of plastic dynamic viscosity and the Casson fluid. Furthermore, it was observed that a corresponding increase in the stretching index $(n)$ increases the skin friction and decreases the energy and mass gradient accordingly. The relocation phenomenon contributes to a decrease in the thermal process, while the temperature gradient attained maximum within $(0.4-0.6)$ variation of the Casson parameter.

在本文中，考虑了具有MHD和耗散效应的卡森流体上的Cattaneo–Christov热流重排悖论。人们认为浮力和生热效应是自然对流的原因，而可变特性则被视为与温度有关的线性函数。在给定的假设下，方程式的控制系统被制定和转换。因此，因此采用了切比雪夫（Chebyshev）搭配光谱方法来获得近似解。但是，随温度变化的行为在塑性动力粘度的边界层流和卡森流体之间建立了关系。此外，观察到拉伸指数相应增加。$（ñ）$增加皮肤摩擦并相应地降低能量和质量梯度。重定位现象有助于减少热过程，而温度梯度在$（0.4-0.6）$ 卡森参数的变化。
