i wouldn't say that 89 is too hot, but its definitely hot! try nzxt cam software to get in-game real time cpu temperatures in the corner of the screen.
dont always trust peoples
Ok, try running a custom fan speed, like 60%. You can do this using MSI Afterburner. See if the temperature stays below 75 degrees this way. If not, you might need to re-apply thermal paste to the GPU.
Thanks Leo and RCF I'll give both of those things a try and see what happens, cheers
Those are stock/reference models, except for the Asus DC overclocked maybe. MSI should stay below 75.
You cant just make up temps without knowing the ambient temp.
In any normal circumstance between 18-24 degrees it should stay around those temps. I'm going to automatically assume it is if there is no mention of extensively high ambient temps, because I think the OP has ambient temps past 25 or even 30 he would have mentioned it. Harsh to downvote on it.
technically its not too hot though, its totally within spec.
Ok, if you want to argue that have fun. I think It's too hot, not necessarily in danger of the GPU. It should do better, that's the point.
