Is it possible to undervolt the i7 4790? My temperatures at full load reach 80+ celcius at times. I have a gigabye h81m s1 motherboard. If it's possible, how do I do it?

If you're using the stock cooler and old thermal compound I can see why you're getting high temps. 1.25V is probably overvolting it. Though it's still within the safe limit you're temperatures will probably increase. Try 1.05V and underclock a bit if you must. Lower voltage usually means lower clock speed unfortunately. I would at the very least clean out the heatsink if it needs cleaned and redo the thermal compound before losing out on performance. 90c although it's a very high temperature isn't dangerously high. 80c is high normal. I'd worry if it was constantly shooting to 100c and throttling. Even at 88c there is little need to worry. Temperatures over 85c constantly can degrade your CPU over a period of years. But like you said it...

I'VE GOT a 4790(non-k) in another computer and it's a workhorse
you might try downloading intel's XTU "(Extreme Tuning Utility) - it will give you the ability to adjust voltage from windows versus going into bios - much easier

Hello thanks for helping. I have no experience in undervolting. What would be the usual safe values?

1.25 V would be a safe voltage

But like you said it only gets up to 80c+ sometimes.
