High temps on a 4690k after switching from ATX LAN case to traditional tower

My original build was in a Cooler Master HAF XB, the weird giant LAN case that I somehow thought would be nice to have. Long story short, it was garbage so I bought a Define r5 from Fractal Design. Rebuilt about 2 weeks back, everything is functioning as intended, but my overall CPU temps are a lot higher than they used to be. Idles were around 40° before the switch, now they're up to 47-50°, in games it's usually in the 60s, I did a stress test today with IBT and it was nearing 100° after only a few minutes, before it stayed in the 80s.
Before anyone says it, I am in Southern California and it has been hot as hell lately. This could just be the higher ambient tempuratures, but I don't know how that would account for gaming and stress test temps being so much higher than they were before. On my old case, the motherboard sat flat and now it's upright. I didn't change the heat sink or anything when I rebuilt, is it possible that going from the old position to the new one somehow messed things up with the cooler? I don't just mean in movement itself, but can the thermal compound setting when the motherboard is horizontal be messed up by being reset upright(if that makes any sense at all)?
Any input is welcome, thanks bunches in advanced.
 
First whats your hardware besides the case?
Second, if you're getting a massive spike in CPU temps look at what changed. You've had pretty big change in airflow, that could be lending to the issue. Do you have more hardware sitting in the path of the air than you had before?
Also if it's been long enough and hot enough (fellow SoCA here, this summer has sucked) your thermal compound may be in need of cleaning and reapplying.

My first suggestion would be to try reseating your heatsink with a fresh clean/reapply of thermal compound and see where things are from there.

Bumped the fan speed up, gave me like 1-2°

Gotta disable all that auto-OC crap I have enabled

Asus Z97-Pro
i5 4690k, no OC other than that AI tweaker thing I need to disable
Noctua NH-U12S
8GB DDR3 @ 1333MHz(total accident) fron Crucial
EVGA GTX 970 SSC
750w PSU from Rosewill
128Gb Sandisk Extreme II
1Tb Seagate Barracuda


There's nothing new in the way, but the setup is so different. This case has 2 drive cages, I removed the middle one that I don't need, so there's really a straight shot from the intake fan to the heat sink and the exhaust fan is in the usual spot right to the left of the cooler. There's only 2 fans though and they're pretty terrible from what I can tell, I'll probably end up buying 3 Noctua fans, so I take advantage of the big intake in the front and have a capable exhaust fan.
Worth noting that my 970 has also gotten a bit hotter, about 3° at idle.
 
So we treat this like you just have this build. And do the same as what we usually do to lower CPU temps.

The Noctua should be good and not need replacing. Sop just re-seat the cooler. There is some chance it was bumped while transferring the mobo to the new case.

Yupp that was it, reset BIOS to default. The default voltage is 1.032, it bumped it up for a really tiny OC, like 3.57 or something, it didn't even show in CPU-Z, just BIOS.
