Corsair H80i and high temps?

I've got a 4790k on a Z97X-UD5H with the H80i. I feel like my temps just aren't right.



At idle I'm getting 28-30 celsius. This seems pretty good to me, but I thought it would be around 20 celsius.



When I run Handbrake to convert a video to h.264 my temps jump up to 80 celsius. This seems like it's way to high. Also, if I look at the temps of the all the cores of the 4790k they look like this



Core 1 = 79

Core 2 = 80

Core 3 = 80

Core 4 = 65



Since Core 4 is 15º cooler did I get a bad i7 processor?

Or do you guys think it has something to do with the paste/mounting?



I'm using the paste that came with the H80i.



Also, my processor Vcore when set to auto is 1.248 (which is pretty high)

I undervolted it down to 1.150v and set the over ride to 1.170 and get an actual 1.164v

Machine is completley stable at this vcore and standard 4GHZ with 4.4GHZ Boost.



Attempts at overclocking have been abandoned because of these high temps.



I’d REALLY like to figure this out. Hope someone can help! :)
