I am using a hard cover for my 13" MBP 2017. Some of it is covering the air vents but I'm not sure if this is a problem or not. I used the MBP without the hard cover for two days when I bought it and then I went to get the this hard cover and its been on since then (1.5 months now). I did feel a little that it gets more warm as compared to the first two days (when I used it without the cover). But its only a little warm and I think that its normal. But I'm not sure if the case covering the vents is normal or not. Please see and tell me.
P.S. Suggest me a free temperature monitor app.
