Inspiron 15R SE 7520 fan always on?

Recently I’ve been getting worried about my Dell Inspiron overheating. The fan was noisy and air expelled was very hot. Looking at the processes running there didn’t seem to be any culprits. Looking at the device manager I noticed that after a recent Windows Update the AMD driver was no longer running. I went to the Dell support site and installed the latest Intel HD followed by (the order is important) the latest AMD drivers – note that these drivers are older than the ones Windows will install. Once installed the device manager showed they were both happy and the overheating seems to have been resolved. I’m guessing this is related to the horribly bungled dual video card implementation on the Inspiron. A more wild guess is that the AMD GPU was probably running all the time and the joint CPU/GPU cooler was probably struggling and hence the overheating problems.
