Two days ago I upgraded my GTX 970 to an MSI GTX 1070 gaming X and the PC is giving off an odd smell.
I thought it could be the PSU but no smell from it and it's a 1 year old XFX TS 650 gold which from what I know is a pretty decent one.
I also upgraded the CPU to an i7 4790 at the same time, liquid cooled with a corsair h55 so I'm not sure if that could be the cause either.
Temperatures are good, even with valley and prime 95.

It is faint and it's not a burning smell as far as I can tell, is that a normal thing? It has a mild chemical smell to it.

Any help would be appreciated as I'm fairly new to all this.

Can you locate the source of the smell?
A rolled up paper tube to your nose might locate it.

Look in particular to the newly added parts.
If the smell goes away, I would not worry too much.
It is likely solder flux from some giving off fumes as it gets heated and dissipates.

Yeah the temps on the gpu seem fine, doesn't pass 65 degrees when using valley or pushing it to 100% use in the witcher. It pretty happily idles at 30 degrees as well.

It may be the thermal compound, but I think it's the PCB, the has like a little layer that burns away or something (not 100% sure what it is), it will go away after time.

The source of smell must be the new GPU... Dont worry as the temperatures are normal.... Once a new GPU gets a little heated, the spinning fans are giving off the smell of some sort of volatile chemicals used in GPU.... If there is no issue with the performance and the games and softwares are running smoothly, and if the smell stops after 10 to 15 minutes you turn off the pc, then..... NO PROBLEM!!!
( Sorry for bad ENGLISH, as it is not my first Language )
DON'T WORRY, it must be fine.

Thanks everyone,

I opened it up and checked inside while it was running at full load, appears it's coming from the GPU as people expected. It's fainter than it was a few days ago and doesn't smell at all like electrical burning, even had 2 people stick their noses right next to the GPU as well out of paranoia and none of us could smell burning parts.

Was hard to pick the best answer, as everyone helped, thank you all again.
