Why does Kernel_Task keep on throttling my Macs CPU?

When using iMac (Late 2013 27" which has been fitted with an SSD) Kernel _Task throttles CPU. Instead of the CPU running at 3.2GHz, it will run no faster than 0.8GHz and fans run at 3000+rpm. Have checked all temperature sensors and all work fine. The mac is also not overheating. When running Apple hardware diagnostics, it tells me there may be a problem with the system management controller (SMC). Resetting the SMC temporarily fixes the kernel_task problem but it always returns. Any ideas what may be causing this issue?
