CPU running at 40C idle, is this too hot?

[Gummeybear22]

Pretty self explanatory, i have a 6700k, running at normal speed (4ghz). i have a Cooler Master Seidon 120V v.2, my hardware is in a Corsair 300R, with 2 front fans taking air in, 2 on top blowing air away, the back one is the cpu cooler radiator, and one on the side blowing air out. My core temp is 40C when idling, its not even got a operating system in it, its only on the bios.

Any help is appreciated, Should i be worried, or is this normal?

What is your ambient temp in the room? That'll play a big part in any temp results.

Take a look there.

Ultimately, idle temps are not too much of a concern (within reason) - load temps are a much better place to gauge adequacy of your cooling solution.

I assume you're monitoring from within your BIOS (if no OS is installed) so, as an FYI - you're not 'truly' idle there.
You're not using any significant load*, but you're a little more than 'idle' - once you have an OS installed and can idle at the desktop, that'll give you a better idea of a 'true' idle temp.

*I'm not 100% sure why, and I've never been able to find a definitive reason - but BIOS temps are (usually) a little higher than 'idle' temps.
