Lenovo IdeaPad 720S Fan Noise

2019-09-30, 10:13 AM


I bought a Lenovo IdeaPad 720S that has an i7 7500 with 128 SDD and 8 gb of RAM. The thing is that a few months ago I decided to restore the PC and updated Windows too, and after this the computer fans started to sound like crazy, for example when Chrome was open with one web it started sounding a lot. I contacted lenovo services and they changed the fans but even after that it kept sounding. I think is a software thing because the computer sometimes start to sound randomly, for example sometimes it sounds like for one hour and then it shut up. I usually monitor the task administrator to see if a process is consuming too much CPU or memory but I don't happen to find a common task that would be the cause of the fans going on all the time.
Please if someone know how to stop this, tell me about it because it's been driving me crazy and I don't think a computer with this specs should sound this much, specially considering that I bought this computer expecting it wouldn't happen all this and I don't want to change my pc yet.
Sending it to Lenovo Services now it's not an option (I can't right know, and they already changed the fans), restoring the PC neither (I have done it several times), so if anyone has any other idea I would really appreciate it.
Thank you very much
