Is this temperature normal?

[DAfon1]

I recently purchased an intel core i7 9700k and did not overclock it, i decided to look at idle temperatures from 35 to 40, but in games from 65 to 80, please tell me if this temperature is normal or if me need to change the cooling system (now deepcool gammaxx gt)

Intel will tell you that anything up to Tjmax (~100c) is ok. I believe that​ anything up to 90c is more reasonable. If you are seeing only 80c while under load, this is great.
