Good morning Mr. Ohana & all,   Good news is I think I have solved this, although the method is fairly 'clunky'. For unrelated reasons, I rebuilt my 13R2 from scratch. After the rebuild I noticed the problem had gone (monitored over several days). It is not really fair to define the solution as 'just rebuild' , so I dug further into the issue. As my machine is running now, I do not have "Dell.TechHub.Instrumentation.SubAgent" installed. From further research, there seems to be some conflict between the Dell support and Alienware support for the laptop. I found this issue during my rebuild and this has shaped my solution.  1. Remove all Dell an Alienware support tools using "add remove programs" & reboot. 2. Install Alienware Update 4.6.0 (I used Dell-Update-Alienware-Update-Application_3T5JX_WIN_4.6.0_A00.exe). Don't install the Dell update tool. 3. Run Alienware Update 4.6.0 and accept all update recommendations. 4. Once complete, this flags the PC as 'up to date' . No Dell management elements are installed (Alienware only).   This process should leave you with a working config - without the fan problem. I have no device manager errors and my PC is performing well. "Dell.TechHub.Instrumentation.SubAgent" is not installed. I welcome feedback on this, but the problem is solved for me. Regards Stevie            
Good morning all, I am having some problems with the Dell Instrumentation process (Dell.TechHub.Instrumentation.SubAgent) on an Alienware 13 R2. Details are: C:\Program Files\Dell\DTP\InstrumentationSubAgent   - 1.0.106.4173 I am finding every 10-15 min the PC freezes, the CPU fan spins up to 100% for ~1.5 seconds, then the GPU fan spins up to 100% for ~1.5 seconds. The whole event lasts about 5 seconds. I watched the task manager to identify the likely cause. From the resource usage when the fault occurs, I suspected the Dell Instrumentation process.  Using task manager I ended the process. When I did this, the problem stopped & the PC ran normally for extended times. Before I proceed, can anyone provide advice on this issue?   Many thanks and have a good day   Regards,   Stevie
