HP Ultrabooks are generally louder than Lenovo Ultrabooks under load
Looks good for me
Brands almost mean nothing in laptops, only useful in customer support, don't judge a laptop by brand, every brand has good and bad products
 
OP, if you don't game much, I would prefer more portability, get the HP Spectre x360 13

When my gpu idels it sits at  37 celcius,without fans even running, and when i run a stress test it goes to around 72 and fans start, and when i stop stress test the  temps go back down to 37, and fan stops???

If i were you I would reinstall windows, maby in uefi mode, since you have upgraded your system so much system might have gotten a little messed up.
 

Lol almost identical to  my rig, other then GPU and SSD
 

Removing gpu from pcie slot and reinstalling it seems to have fixed the issue

A kernel Update fixed it, once i updated from kernal 4.3 to 4.4.

I am pretty sure it was because i was running an old kernal version

I personally have a RX 580 8GB Aorus card,and it has a ton of coil whine  and plastic finish of it feels cheap like I can brake it. Every time i take it out of computer I can just feel the cheap plastic. If i were you I would aim for a  Sapphire, they seem to have the best build quality in my opinion. Other then that a RX 580 is a great card. 

Define r6 or define c

Fractial Define R5 is What i would go for, I have it, it look great, and is really quiet, and nice build quality.
Though Define R6  is a little nicer.

Ok so you have different issue then the one i had, good luck.
Could be anything PSU,CPU,Motherboard, etc.
I would find a friend who has lots of computer hardware and try testing stuff. 
Or just take it to a computer shop for diagnosis.

When my case was closed, i even reached 100 celcius. I am going to replace it with a  Noctua
