Can a PSU or SSD affect CPU temperatures?

Hey,

As irrational as it seems to me it somehow prove to be true. I'm using an Intel i7 4790k and when I was using an AX860i and a WD Black it peaked at around 76°C when I was gaming.

Now my AX860i has broken down on me and will be RMA'ed shortly. I have temporarily installed a CX750M and simultaneously switched from my WD Black to a Samsung 850 EVO SSD for gaming. Now while playing the same game it peaks at around only 71°C.

A 5 degree improvement from a lower end PSU and switching from an HDD to an SSD, is this normal I wonder? What causes this, if it indeed is?

If full specs are needed, here are my components:

Corsair Obsidian 750d
ASUS Maximus VII Hero
Intel i7 4790k
Noctua NH-U14S
Corsair Vengeance 16GB 1600mhz RAM
Gigabyte Gaming G1 GTX980 Windforce
ASUS Xonar Essence STX
Corsair AX860i / Corsair CX750M


PS: I realize both PSU are kinda overkill for my system but I was planning to add another GTX980 in the future so I left some room upwards.

The temperatures were taken by CoreTemp. At the end of the day I always check what the temperature on my hottest core was. I also check that whenever I exit a game. Ambient temperatures are no different than before. I switched those parts literally yesterday.

Maybe the PSU that's broken now was the cause of the higher temperatures and they are now normal. I'm clueless.

There is this thing called a fair test, where you have to repeat things. You can't measure the temperature, change components, measure again and get your conclusion. That isn't a fair test.
