I just installed my new i7 4790k and under load it has hit 80 degrees. Under load it normally is about 70-75ish. I ordered a hyper 212 evo and it will be here in 2 days. Is it safe for me to use it around 70 degrees for the next 2 days?

80C on stock cooler with 100% load and slight overclock? perfectly expected.

It's certainly not a good temperature, but there will be no longterm damage if you replace the cooler with something better soon

I have seen temperatures like that with stock coolers under heavy load.

Intel would not sell a cpu that would not be cooled within spec on stock cooling. It would take YEARS at those temperatures to damage it(and most cpus are not always under heavy load).

You will do no harm while waiting for a new cooler to come in.

basroil, What is your avatar?

Yes, at 80C it would take years, the issue is more of what happens if the fan dies. Sure it'll throttle if you're lucky, but if you're unlucky it could cause (probably very minor) damage. Fan failures are rare though, so it's more a long term concern.

As for avatar, it's an old rendering of a robot I using. Looks much cooler now ;)

Ok, now instead of it coming in 2 days, it's gonna be here on the 30th(because of the holiday).... If I keep it around 70-75ish until then will I be good?

I see "~70c" tossed around as a safe maximum core temperature, but this number didn't come from Intel.

On desktop CPUs, Intel publishes a "Tcase" maximum temperature, which represents the maximum temperature of the surface of the heatspreader. However, we have no way to measure the surface temperature of the heatspreader. Instead, we have the DTS (digital thermal sensor), which gives us Tjunction, which, incidentally, is what Intel rates the temperature for on their mobile CPUs which don't have heatspreaders. I've seen assertions that Tcase is around 5c less than Tjunction, based on an article published around 10 years ago for a different line of processors which had soldered-on heatspreaders.

For what it's worth, I have never seen a modern "Core" CPU die from heat, and even voltage + overclocking-related deaths are rare. I'm probably going to be unpopular when I say this, but I don't think you need to spend any money. Intel would not sell a warrantied CPU to home users (or better yet, datacenters) with an insufficient cooler. At 80c, your CPU will still long outlast its usefulness to anyone.

well 80c is a bit hot but acceptable as over 100c doe it not shut its self of as it is coded in to do that sure i run at 40- 45c playing gta v etc never over 50c yet. I have the Be quite Dark Rock Pro 3 and sitting at idle it can be around 15-26 in a cool environment are you overclocking , in a hot environment is the heatsink or/and thermal paste applied
