80c on the GPU seems a little high considering the cooler.
Yeah I thought so too, however it may actually be a false reading as the fan is not at maximum speed while folding and it does go faster when I play a high end game. It's running at 1898MHz in Gaming Mode which is overclocked from NVIDIA's specification by the MSI Gaming App, also handy for turning off the RGB light strips on it.
The thermal limit for the card is 90C, it will begin thermal throttling at 85C so if it were 80C you'd think the fans would be at full speed already. The RAM was purely coincidental, they did not have 2 more white modules in stock when I received the second pair (the supplier asked and I said it didn't matter to me what colour they were) so I got two of each colour. They are of course identical specification underneath those spreaders.
EDIT - It was indeed most likely a false reading, GPU-Z has the reading much lower at 75C and the fans at 72%. I'm inclined to believe that more than hwmonitor which still shows 80C

Given it's overclocked I reckon the temp isn't too bad but I will keep an eye during July/August and throw some extra fans in the case if necessary.
