I don't think you can (or should) disable the fans. From what I remember, few minutes after boot the fans will reduce to a level that is acceptable to use in a classroom (that is where I used it for). Compared to other 24/48 port switches, the sound level was very low which was why I picked that switch.
On the power consumption, I think your measurements can be quite realistic. The datasheet specifies 580W total power (AC) with 400W PoE power, so getting to 96W (the 580W is peak) even with a few PoE devices connected sounds reasonable to me. I'll check if I can still find my S1500-48 and see what it draws without PoE devices. Note these switches are quite performant (104Gbps/77 Mpps) so you can't compare them to low-end 8/16 port switches. Also, the switch was already on the pricelist in 2013 (don't have older ones), and network and computer equipment used more power similar to your PC and laptop.
Update: I just connected my S1500-48P to a power meter and it shows around 55W of power consumption when booted up (peaks to 65W during boot) and the fans sound pretty quiet for an enterprise grade switch, though you can hear it in a silent room.
Update2: I would expect the S3500/S2500 to use even more power, given the modular design. I assume you are aware all MAS switches are end-of-sale for some time and reaching end of support by the end of this calendar year?

Thank you, :-)
Is it possible to shutdown the fans when tempeature under 60° C ?
There are very noisy.
Another question the 48port need lot´s of Power 96Watt i have only 6 Ports with PoE Clients and 24port in use.
Before i have a 16port switch and 8 port PoE, this need 55Watt.
The S2500 or 3500 with 48port need less Power ?

USB is one option, Koen already shared the link. You can also upload the new firmware to the WebUI if you have access to that, or us tftp to pull the firmware from an TFTP server. I personally mostly used the WebUI upload as you don't need to put files on a USB stick.
