I bought a new Dell Inspiron 5570 a little over a month ago. Right from the start I've had issues with the fan getting very loud, seemingly for no reason. I'm never doing anything very intensive, and I've even had this happen when I've had the laptop on but haven't been using it. What happens is that the fan will suddenly kick into action out of nowhere (it doesn’t seem to be a reaction to increased CPU usage) and ramp up to a volume high enough that you can even hear it from outside the room. It then calms down fairly quickly, but always starts up again before long.
I tried various things to troubleshoot the issue on my own – updated all drivers and the BIOS, ran diagnostics (no issues reported), checked for viruses, and even restored to factory image. I've also fiddled with the power settings (system cooling policy, maximum processor state). Finally I managed to talk to Dell and they arranged an engineer visit which took place yesterday. The fan was replaced, but the problem remains.
I have installed Intel's Extreme Tuning Utility to track the laptop's temperature. Prior to the fan replacement, the program was reporting frequent thermal throttling. Since the fan replacement this is happening less often, but it is still happening occasionally. The average temperature tends to be somewhere between 50C and 75C, but it regularly spikes into the high 80s and even 90s, seemingly at random. This usually coincides with the increased noise from the fan. Last night I even noticed that the part of the laptop to the right of the touchpad was very warm to the touch.
Yesterday I used my old HP laptop all day, and despite it being a few years old now, the temperature never went above 80. Again, this Dell is a new laptop. I don't feel that I'm doing anything that should cause such high temperatures. I have it on a flat surface at all times.
It seems I’ll have to contact Dell again, but I thought it was worth getting some input from other people. I’m not an expert and don’t even know if these temperatures are really something to worry about, but something definitely seems off to me. I have no idea if this is actually a fault, or if could simply be how this particular model is made.
