My 2015 Macbook PRO early 2015 makes fan noise often. It does not have a T2 security chip. It is on a laptop stand that allows heat to escape. Please let me know how to turn off the noise.
Run the Apple Diagnostics to make sure the cooling system is functioning normally.
To look for software issues run EtreCheck and post the report here using the "Additional Text" icon which looks like a piece of paper.
You could try a SMC reset.
The fans will come on when the chips inside need to be cooled (actually, they're always on but at idle they spin at 1,500-2000 rpm and you don't hear them). You cannot and should not 'turn off the noise' (unless the fans are speeding up inappropriately, which the SMC reset should fix). You can check Applications > Utilities > Activity Monitor to see if process(es) are using significant CPU capacity – if so, that's why your fans are speeding up.
For example, on my 16" MBP the fans normally are around 1,800 rpm and silent, but when I convert a batch or RAW images to jpgs, the CPU activity goes above 1500% (meaning the Mac is using nearly all the capacity of the 8 physical and 8 virtual cores), the CPU and GPU temps go up, and the fans spin up to ~5,500 rpm and become 'loud'. Then, when the batch of images is done, the processors quickly cool down, and the fans gradually return to <2,000 rpm. The same basic thing happen on my 2011 17" MBP (which is well before T2), except that there weren't 16 cores so the export took much longer, and the fan speeds were ~2,000 rpm at idle and ~6,000 rpm at high load. Bottom line is that's normal behavior.
I did the reset many times in the past, but the noises still come back.
Would you post the fan noise of the MAC laptop without T2 security chip?
