z170 Chipset/ PCH getting HOT!

[Syed_19]

(The thing which says G1 gaming is what I'm referring to as z170 chipset since I'm not sure what is it called.)

I had a problem with my P.S.U. At the time my z170 chipset was not getting hot at all (atleast whenever I touched it just check everything is hot or not). I had to change my P.S.U so send it and got it back in around 10 days. During that time I bought another HDD for my system. Everything was working fine after I received PSU, but then I touched the z170 chipset and it was really hot to touch. Right now I'm using the gigabyte easytune just to check the PCH and System temps. And it is around 48 and 39 respectively. When I switched on my PC, the temps were 41 and 33 and then they gradually increased with time. Since then, I'm only browsing on chrome. And also changed the thermal paste I don't get it whether it is because of the HDD, thermal paste or something else. Please HELP

System:
i7-6700k
Gigabyte z170x-Gaming 3
2x8G vengance
Cooler master seidon Ver.3
PSU Seasonic G450w
Samsung 850 250GB SSD
WD 1TB HDD blue
Without case

1| What sort of a problem did you face with your PSU?
2| Without a case to house your components you aren't getting an optimal airflow over critical components. Chipsets and VRM are among them.
3| The baord's chipset heatsink

lacks any form of heat dissipation capability which is why you're seeing it reach to those temps. A simple solution would be to have a fan pointed at the area and you should see about 4 degrees C drop.
4| You didn't mention the aftermarket thermal paste you used on your chipset.
