Hi my relative has a computer that is making a really loud noise I believe its the fans. (It sounds like a vacuum cleaner that's in the next room, not as loud as if were next to you but distantly away) However, I also noticed it is making the room extremely warm. I suspect overclocking. He is not all that tech savvy with computers and He got the computer from a long time friend of his. So he has no idea what is going on with the computer or what his friend did to it.

I know he is running a i5 3570k
HD 7770
850 watt power supply (i believe this is overkill)
16 GB ddr3-1600 ram
has a cd dvd drive
has a sd card reader installed in a 2.5 floppy bay. Finally he has 2 fans running into his computer. Not including the fan on the the processors heatsink.
My question is this what can I do to bring down the noise and the heat. I personally never overclocked a computer before. So, any suggestions would be deeply appreciated. Thank you

PS I also understand system bios/UEFI as I took classes for basic computer maintenance in High school, but was never taught about overclocking.

The easiest way to get rid og overclocking setting is going into BIOS upon starting the computer and setting everything back to default. You can also tweak the fan speeds there. Save and quit!
Once done, you can monitor your cpu utilisation, core temperature and clock speeds with a software such as cpu-z.
If they are back to normal, but the fans are still loud, clean the dust from the pc case and look up what kind of fans you have in there, you you can replace them. Fan bearing can wear off and get loud by time.
I hop I could help. Feel free to ask further questions if need be!

Do you have any advice for the processor? I found after doing a temperature test that the CPUs at 70 degrees and it does not go down from there. I believe the heatsink with its fan will need to be replaced, but for the mean time while I am waiting is there anything I can do?

If you have thermal paste at hand, reapply it and mount the old cpu cooler back. Sometimes that itself does the trick.

There is a great variety of socket 1155 compatible cpu coolers. I do not know how much space you have in your case, but just under 155mm the be quiet! Pure Rock (BK009) and the Thermaltake Frio Silent 12 are fitting replacement.

There is also a way to underclock the cpu, lowering its target speed and voltage. That results in lower temperatures as well and would be a good temporary solution. Here is a guide https://www.techradar.com/news/computing-components/processors/complete-guide-to-underclocking-642385/2
