Need to reapply thermal paste? Core temp ~50C

[Sidiox]

So I've build this new system about 2 months ago and I'm not sure but I think the core temps are a bit high.

 

When I'm just doing my normal school stuff my CPU (i7-4790) gets to around 20% CPU usage with 12Gb of ram in use  (I run 150 tabs in Chrome, so yeah) the CPU temp given by my motherboard is around 35C, but the core temp reported by my CPU itself is 45-50 degrees.  Now I wonder if these temperatures are a bit on the high side of things or not? Under heavy load (ie fluid simulations in Autodesk or gaming) it gets to around 60 degrees but not much hotter than that

I'm running a Scythe Mugen 4 with 1 800 rpm fan (the other one is used in another spot in my case and doesn't fit on the cooler because of my rams heatspreaders)

This isn't a bad cooler (also not the best) so I would think that it would be capable of keeping my CPU a bit cooler than this, so I wonder if maybe the thermal paste that came with it is just bad or maybe I just seated it a bit bad. What would be a good replacement thermal paste?

If you want to reapply the paste then it might decrease temp by a few degrees but it's not Necessary. Them temps seem ok and your load temps are good so there is nothing to worry about.

If you're running your CPU fan at [450 rpm] then that's possibly why you get some "high" temperatures.

None the less 60 degrees isn't bad on aircooling

Well atm it is even at 400 rpm, but that noctua fan is really making pushing a lot of air

Okay, I don't think I will then, although I might try some stuff with the fans themselves to get a few more degrees

150 tabs? 

Probably with 8 cores i could do a lot of tabs... to lazy.

I'm also a owner of i7-4790 and my temps are same with hyper evo 212.

Light use 45 degrees, heavy use 65 degrees absolute max.

My turbo boost is off, don't need 4ghz.

I used hyper evos thermal paste but plan to buy arctic or diamond or w/e they are called with noctua f12 (I want silence !)

i got a 4790k at 4.4 and still runs at 45-50 so i thinks it's slightly high but nothing to worry abot
