Sorry if this is a duplicate question, I found others like it but nothing close enough.

So about a couple of days ago I noticed that my watercooled MSI GTX 1080 Seahawk started running extremely hot when I tried to run any games, hitting 95°C and causing visual stuttering and tearing.

This started happening around the time that I installed Zorin and Ubuntu onto another drive but I've since removed them and I think this might be coincidence, though I don't want to rule it out.

Typically it will happily sit between 35°C and 50°C when idle but will climb to 95°C when any sort of game is started, even fairly undemanding ones like Factorio.

Is there anything that I can do to fix this? I bought it back in January, am I still under warranty?

My specs are:
Windows 10 on a 60GB SSD
i7 4770k stock
GTX 1080 Seahawk stock
8GB RAM
Asus Maximus VI HERO Motherboard
800w Corsair PSU

(I'm in the middle of upgrading to fix the imbalaces)
