Hi, new to the forum. I just bought a new SP3 i3 128gb. I remember reading about overheating with the SP3 and mine is starting to do it. I finally decided to download just the trial of Artrage onto it last night. After a couple of hours on it of internet browsing and looking up art programs, I downloaded the trial Version. I have the full version with a Wacom Intuos I bought and really love the program. However once I started to download, I started to hear the fan start to go. Not bad or that loud that it bothered me. Then when I started to play around with the app itself testing pens and brushes, it started to really get hot down on the bottom portion of the tablet towards the middle on to the side where the charging port is. It was not plugged into the charger at the time. I had to turn off, because of the heat getting to me holding it. Today, I tried again and did a line drawing on it to see if it would act up again.. Sure enough after awhile the fan started going. Only difference is tonight I got my case for it, and it was in the case. Still got really hot, to wear I just turned it off. I guess I'm wondering now if maybe the Artrage app is too much for the i3 processor. The only thing is, it's just the Trial Version of an app. Not the full blown Desktop Version I may want in the future for it. Not sure if it's a bad unit or something I can get fixed by settings or doing something else. I like everything else about it so far, doesn't seem laggy in the least, but did slow down in the Artrage app the first time it got hot.. I know I read a lot of artists buying the i5 or i7, but not sure if I need them or not. Using as a laptop, but mostly for drawing on to replace my Samsung Note 10.1 (2o12). I really love the Surface Pro, but didn't want to spend all the money on the i7, but I can maybe afford to go with the i5, but only with the 4gb of RAM. Is the i3 powerful enough for this program or app? I know it's a good program. I used sketchbook on the SP3 and I use it on my Samsung Tablet, so I'm familiar with it, just prefer Artrage. Thanks in advance. I will call support tomorrow to see if something I can do, unless you guys can help me out.
