Eazon Posted November 27, 2021 Share Posted November 27, 2021 Hello ! I have bought a RM750 brand new a couple months ago or so, and after noticing that the fan would randomly spin while in idle/browsing, despite pulling less than 100w (reminder, this 750w unit should only have its fan start spinning when around 300w (40%) of power draw) Room temperature is always around 20°c or below, After a few weeks communicating with the support, we finally settled on an RMA process, and i received the new unit yesterday, installed it this morning. After about one hour of use, only browsing and watching youtube, i noticed the exact same behavior. The fan started audibly spinning for around 15-20 minutes before finally stopping again. I don't really understand how this is possible. The replacement unit i received is apparently a refurbished unit, is it possible that it suffers the same defect, or is it actually how the psu should behave? I still believe that the RMA was worth it, as the previous unit would not only have its fan spin but also emit a very annoying vibrating/humming noise, that doesnt seem to be present with the replacement unit. But i have a hard time understanding why it is behaving that way. And yes i am 100% certain it is coming from the PSU, i have made sure of it many times before even contacting the support. Feel free to ask what i did to make sure. Has anyone experienced similar behavior and can tell me if its pretty normal? The support assured me that the fan should only start spinning at 300w+ load but i'm starting to wonder if its not just spinning after an hour or two to exhaust hot air buildup, in which case i feel marketing is just not fair.
