IIRC, the ghost isn't great for temps. And those bitfenix spectre fans have very little static pressure so if you have any little side gaps (vent holes) at the front for intake, there won't be much cool air being pulled through.
Adding 2x120mm crappy fans at the top of my antec p100 have def. help with my cpu temps, was easily going up to and even above 80 degrees, now they don't go above 70.
Also, last night after a good few fours on bf 4 MP, I noticed that my temps were pretty damn low with a rather low fan speed:
So I went and played metro last light for about 15-20 min and temps were back to 85 with a rather high fan speed:
Overall, my temps weren't bad after playing bf 4:
edit:
Yep, they are
Surprisingly light, though.
I find this MSI card rather heavy!
