I Just built my new i7 4790k rig. Cpu cooler is the Noctua NH d15.
I've lowered my Vcore to 1.189, most other setting are on normal or auto, no overclocking yet, but all 4 cores go to 4.4ghz with boost.
In prime 95 blend test all seems good, I get low to mid 50s with 4 cores at 4.4ghz. (just boost doing this, no overclocking) I idle in the 20s.
Prime 95 small ffts, It goes straight to the low 80s and stays around 80-85 degrees! Is this a normal temp?

You can just download SpeedFan from net and manually set the cooler speed and stuff. After downloading, set the target temp to 50C or 55C and speed to 100%.Thats a good idea, but I actually just found the setting in bios. I maxed the fan speed, ran small ffts again, and it shot up in temp again but not quite as high, went into the 70s to low 80s range, instead of 80-85. Gained an about 6 fps. I didn't run it for long, and I am not going to run my fan 100% all the time, so I will need to do as you said.

Fair enough, check out the way I suggested about fan speed. Ok, but is the 70s to 80s range even normal for that cooler for that CPU. When I google it, I see many people have had overheating problems with the 4790k on small fft test, but can't find many comparisons with my cooler to compare to.
I can try re-seating and re-applying paste but thats a real pain if it won't benefit the heat issue.

No it isn't normal. From what I've seen, and considering your idle temps, I'd say 60s and upto 70C would be considered fine. Mid 60s would be what I'd say ideal which such a great cooler without OCing. i7 sure goes into 70s and 80s but with stock cooler, not D15.
First try the software way of adjusting speeds and stuff, then we can move on to hardware.

I couldn't get speedfan working. My cpu is running 4 cores at 4.4ghz even though it's turbo boost doing it, it's the same as if i oced to 4.4 is it not? Either way, I really want my temps down. Thsi sucks!

The clock speed is not an issue, turbo boost will increase the speed to 100% stock (4.4Ghz) on stress. Its not the same as OC 4.4Ghz.
After OC, your CPU will be constantly on 4.4GHz even in idle, on the other hand, via Turbo it can shift anything between 1.6Ghz to 4.4Ghz depending on load.
Your should try re applying Thermal Compound.

Unless you disable c-states, your cpu will clock down as low as 800 mhz in idle, even when oc'ed.
As for you temps, they are not to worry about, albeit a bit high. I myself reach 90's in prime 95 after just a few seconds but never cross 65c in rendering+gaming+whatever else at the same time. However, you should still try to reapply thermal paste and reseat your cooler, as a noctua nh-d15 should certainly do better than 80c in prime, especially with those low ambient temps. As for applying too much: barely possible. I applied thermal paste at least 10 times, less and less, already thinking I wouldn't apply enough. But my temps kept dropping. As thin as possible is best.

I re-applied thermal compound using slightly less than last time, temps are now about 5 degrees HIGHER!!!!!!!

Have you spread it evenly accross the surface and made sure the heatsink is perfectly touching the surface at all points, check horizontally.Used pea method, and yes. At least my processor actually works though,(even if hot) which is more than I can say for my new r9 290 that was supposed to be a part of this build.

What happened to the gpu then?Black screen of death. Won't play games at all, just black screen requiring boot.
I had an 850 watt psu, thought maybe it was getting old, so I put in my Antec high curent gamer 750m which is newer out of my other rig, and same thing ... black screen. Apparently it's a pretty common problem with r9 290s. Mine was the Saphire Tri X version.
IT is now back in the box ready to try and get a refund. (Although I feel like smashing it)
back to cpu though, I've been making progress with temps, turning off turbo boost and manual ocing. I've just been sticking to 4.2 and trying to see how low I can put the vcore stable for now. I will later try 4.4 the same way.

The gpu is actually excellent but you have got a bad piece it seems.Anyways, temps with your setup should not exceed 70c in prime95, try playing around with voltage but not too much.
2 of the cores right now stay at about 69 degrees, the other 2 are closer to 79 degrees, but that's still an improvement.
EDIT: I just tried an older version of prime95 because I read somewhere the new version causes haswell chips to overvolt in the small ffts test.
Anyway, I ran the small fft test in Prime 95 version 266, and my temps were 52-59 degrees.
Is this relevant information?

Do don't look at individual core temps, they're warm but the package temp is actually more relevant.Package temp for the older version of Prime 95 (v 266) ... Stays around 59 degrees in the small fft test.
The newer versions of prime95 seem to significantly add heat to the small fft test.
