My brand new build is having overheating problems...

At idle my PC sits at 50+ Celcius
If I open any program or install something it gets up into about 80+ Ceclius and my fans starting spinning harder.

Things I've tried:

Resetting CMOS and BIOS
Re applying thermal paste (so many times)
Re seating heat sink (so many times)
Made sure there was no dust anywhere.

I've tried all this so many times...

Also, when it says its this hot I checked and its pretty warm around my heat sink and CPU

btw my specs are:

Gigabyte GTX 970
NEX 750B
32 GB RAM
MAXIMUS VII HERO
i7 4790K

Idk what's going on... Anything else I can try or should I just go ahead and RMA my CPU or Mobo???

This is idle:

This is just me searching on the internet:

Its not overheating before it reaches 100C.

Also you seem to have disabled all kinds of power savings. Enable it again. Plus disable the multicore enhancement since it seems on.

Idle frequency is 800Mhz.

Reset your BIOS to default to start with and then see. Then disable the MCE in BIOS.

And if it still doesn't idle, make sure the power plan in Windows is reset.

Ok I reset my bios and disabled my MCE. It wont let me save the power saving option when I select it in BIOS for some reason but here is idle now.

It's fine now but like in 10 minutes out of nowhere I could be sitting with nothing opening and my fans will spin up and get up to 80c

Make sure you use latest BIOS.

Did you do a clean install of the OS?

And remember, it can only run 4.4Ghz on 1 core at a time. Else the BIOS is auto overclocking it.

I'm gonna update to the latest BIOS here in a minute.

Yes I did a clean install as in from the disk right? not downloaded from somewhere.

And ok I haven't tried nothing yet this is all stock and just built like two days ago.. Does anything else look weird to you.

This is it now just sitting and searching web pages

If you are using the stock cooler something like ~40C idle is ok. Remember it will first throttle at 100C. So anything below 100C as such is fine.

You can see frequency lower down in hwmonitor.

If you use the stock cooler. You can consider buying a 3rd party cooler or Intels TS15A cooler. If not for temperature, then for noise reduction under heavy loads.

I bought a H100i GTX but it was DOA :(

By the time I even get to BIOS its at 97+ Celcius and the fans on it are spinning I guess the pump went out or something...

Has this been reviewed anywhere, do you know? I'm just wondering if there's any reason for anyone to buy this instead of a 3rd party cooler.

I didn't see any yet.

But those using one seem quite happy for it for what it does.

1500rpm (25% PWM) keeps my 6700K at ~75C with Prime95 28.7. Very silent.

80C just for searching using the browser is very bad and its not ok.
Theres probably something wrong with the thermal paste application or the seating of the heatsink. The stock pushpin heatsinks are giving some people problems and theres a guide written up by a mod here on AT.

It's been doing much better since I disabled the MCE but now I'm installing drivers off a cd and it's going up to 60-99 degrees celcius??? Is something else wrong or will liquid cooling stop that?

I actually set it to balanced ealier. So, I updated my bios and changed all my settings backs such as disabling MCE and now I'm surfing web pages getting 70 degrees celcius :(

Gonna get another liquid cooling system with some arctic silver. Which I don't think that will fix it but it's worth a shot....

Have you checked whether the heatsink is installed properly? It's the simplest explanation. The first time I installed an Intel HSF (ie. the socket 775 and beyond type), I got it wrong without it looking blatantly wrong at a glance.

My 4690k (stock freq and cooler) idles at about 31C, and about 67C full tilt.
