Right after I typed this I opened task manager and BOOM I'm back at 30-40c LOL wtf...

Check for malware. Or do a clean install again. As I said, if you downloaded from alcpu, you got infected.

It sounds to me you got one of those mining type malwares, whenever you open taskmgr everything looks rosy. Close it and it goes bad.

And if you cant get 800Mhz idle frequency something is wrong.

Just hit 100c installing new windows

So RMA mobo or cpu?
What temp do you get in bios? if it's under 50c, then it's definitely malware, otherwise, just a bad mount.

Looks to be a bad mount / faulty pump. Or maybe you are just like me and running things fully passively, with zero ventilation. These higher temps are absolutely abnormal under normal circumstances. Maybe get a branded computer, instead.

I would like some clarification of that, please. It's known that the "download" link on Alcpu for CoreTemp has some really nasty adware, but at least up until recently, you could click on "more downloads", then click on "32-bit" or "64-bit" and download the appropriate version in a "clean" ZIP file format, with just the programs.

However, I recently freshly install a Win7 64-bit system, onto an AMD Brix quad-core machine, and after I got the drivers installed off of the included CD, and then installed Waterfox, CPU-Z, and CoreTemp, I did Windows Updates.

Then I got errors. The first error code, I looked up, and it said WU was too busy, try again. I did that a few times, then I got a different error code. I looked that up, and was lead to a thread on answers.microsoft.com. The thread said to reset WU stuff, and some of the posts from official people, said that it could be caused by a malware infection, specifically TDSS or whatever. One person said that they got that error, and when they replaced their NIC, it went away.

I did WU a little later, and it didn't have problems.

Some people said that the wifi on the Brix was poor or flaky, so I wonder if that is/was my problem, or if I indeed have malware?

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.

Yes I have.

I get about 42-45c in BIOS and I've been getting low 30's to low 40's at idle now. Once I open a game or install a driver or something is when it goes up to 70-100c

I've been idling better at about 30-40c and my frequency is only 3500MHz but I can't play games or download drivers without it trying to overheat...

This is when I'm on the internet now...

What's the chances of me getting a faulty stock cooler and a faulty H100i GTX??? Everything is under warranty so I can get whatever is wrong fixed I just need to find out what it is.

I'm checking for malware right now with malwarebytes.

Malwarebytes said 21 threats detected non malware detected and I removed it but temps are still the same. I have clean install of windows 10 also...

Maybe mobo is sending false temps or cpu is just bad?

Did you update the bios? You said you were gonna but never said you did.

Any unknown devices in device manager? Just wondering if you loaded all of the latest motherboard drivers from Asus.

Sorry, yes I did update my BIOS.

No unknown devices and I have all my drivers I hit about 97c installing them lol

It's pretty clear that something is wrong.

It's unlikely to be the CPU, though it's possible.

My 4790K doesn't even get nearly that hot running the burn in test using an air cooler.

That's either a loose heatsink, or bad numbers.

100c would give you throttling.

Run Intel's XTU and see if you are getting throttling during those high temperature reports.

What do you mean bad numbers like a false temp sensor.

And ok I did a stress test on it yesterday and I hit 90c in like half a second lol

When it says its that hot i feel around my heat sink and it honestly doesnt feel that hot

If you hit 90C in half a second, then you will be throttling shortly.

Is the chip throttling or not?

If it's throttling a lot, then it is indeed getting hot and the numbers are not wrong.

So, I would run XTU and use the graphs to see if the chip is throttling to save itself.

What percentage should the termal throttling be at?

You don't want any thermal throttling at all. It's thermally throttling because it's too hot, and you never want it too hot.

Plus, you lose performance.

Ok I just did a 30 second stress test and it got to 98c then I stopped it. but no throttle percentage...

So, what do you think is going on?

My MHz is about like 3000 and my voltage keeps spiking from 0.7 to 1.2

Do you think when I get my new liquid cooling and arctic silver 5 that will do the trick or do you think its something else?

30 seconds?

Let it go and it will throttle. It throttles to protect itself, so some throttling for test purposes is okay.

Throttling is proof that the chip is in fact overheating and you are not seeing false temperature numbers.

This probably means your heatsink is not doing much.

Or possibly your mobo is jacking the voltage up too high for the chip?

If your chip is thermal throttling, and your heatsink is not hot, then you have a heatsink problem.

A heatsink that is correctly mounted, but too small for the job, should be hot.
If your heatsink is getting very hot, then it's too small for the job.

But you have to let a stress test go for long enough to check these things.

Ok it throttled quite a bit on the percentage...

and how can i fix or check the voltage to see what it is supposed to be at.

When you run the stress test, what CPU multiplier is showing on CPU-Z or XTU?
