im getting fps drops in all games which i didnt used to have. i have looked for a few hours for a resolution and have tried multiple things like, disabling cool n quiet mode in the bios.

specs-
cpu- AMD FX9370
gpu- GTX 1070
ram- 16gb
psu- corsair CX600
hdd- 1tb WD Blue (i have had this for almost 3 years)

ill play on 1080p maxed out setting, the FPS will go from 150 to about 40 for a second or 2, this will happen every few minutes and it is really annoying. Any help would be appreciated.

If it is stock speeds, (4.4 - 4.7 with boost) that voltage is ok. Your CPU is the same as FX8350, just better quality(binned). It is basically an overclocked 8350, thats why it requires so much power and needs a liquid cooler.

First off that PSU is not a very good unit, and I would recommend replacing it with at tier 1 or 2 unit, asap. http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html

The FX 9370 is a very power hungry CPU, and it doesn't take much to make it unstable. Unstable power delivery, be it from the PSU, or the motherboard can be big factors. Another is temps. A 220w CPU is not easy to keep cool. I would check your temps, using AMD overdrive.

is there an way i can check before i buy one becasue i have had this power supply since i built the pc almost 3 years ago and its been fine, the problem has only come up since i added the gtx 1070, my old card was a r9 270x

If the thermals of the CPU and GPU are not high enough to cause thermal throttling, PSU may be the problem indeed. There are a couple of possibilities here to consider, but please test your components with some benchmarks while monitoring temperatures to find out if something else is off first.

Your power supply is not a terrible unit, however it is not designed to be used at the limit. Your 12V rail is capable of outputting 552W, as it says on the box BUT the efficiency is dropped significantly as the load and temperatures increase. The maximum temps your PSU is designed to work under is 30 C. As I stated before, 1070 requires more power than your previous card under full load, which may be causing your PSU to reach its upper limit. This is not a good place to be, for all your other components. (It may literally catch fire if it fails to shut down)

If you are on a budget, I would recommend this unit as a minimum:

my cpu temps after around 5 hours of playing games such as rainbow 6, gta and overwatch are around 70'c but i expected those temps from my cpu, and my gpu has been the highest of about 60'c usually around 50'c. im not on a budget but the less money it cost the better. btw do you think its worth me downloading drivers and installing my old card to see if it is the problem ?

Check your monitoring graphs and try to find irregularities when you get those FPS drops. This is important because your hardware may be overheating for a moment and in order to cool itself down may be lowering your clocks etc. If it turns out there is absolutely nothing going on and your CPU and GPU clocks are staying stable, other than trying out a new PSU or another 1070 I do not know what else you can do about it. (Except doing a clean install on your drivers, adjusting windows power options etc.)

Also this may be an interesting read.

okay, i think what im going to do is get a new psu (cx750m) tonight (will come tomorrow) if that doesn't work ill send both new psu and 1070 back. not sure if i should try a new 1070 tho

Try to do a clean install of the drivers with your old card using this:
http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

Also change your advanced power settings, there are some options there related to CPU cooling and PCI slot management. It may even be a software issue caused by drivers at this point.

Do these and play CS:GO or whatever game you want with your old card, while monitoring GPU usage with Asus GPU Tweak / MSI Afterburner. If you still experience frame drops, check your graphs and tell me what is happening.

i did what you said and used the DDU to uninstall my nvidia drivers and when i played a game with my old GPU i saw that it is not my GPU at all i think it is my CPU, the afterburner monitor shows that when my CPU hits around 76'c it throttles and goes to to about 10% usage from bout 40-50% and the temps go down to 60'c, i didn't expect the CPU to be throttling at those temps that's why i didn't think of that. So whats the easiest fix.

BTW my CPU cooler is a cooler master TX 3 with a noctua NF-B9 redux on it.

Ok this would be easy to explain if your old card did not show those problems as well after you put it back. I would call it "because the 1070 is a more capable GPU, your CPU has to do much more work thats why it is overheating" (On a hot day I would be very uncomfortable if my AMD CPU reached 70) But this does not explain why the problem persisted even after you went back to your old setup, which you say did not have any of these problems.

Alright, your CPU is an extremely power hungry one at 220 TDP thus the heat it outputs is significantly higher than anything else from AMD. This is why AMD recommends water cooling for your CPU. There are some pretty basic All In One coolers out there for budget minded people which should work just fine. I have a Hyper TX3 Evo myself and I can say, it barely keeps my Phenom II 965 in check. It is not capable of cooling your CPU sufficiently.

This is what AMD is shipping the chip with now:
http://www.newegg.com/Product/Product.aspx?Item=N82E16835703027

However a lot of people recommend 240mm rads because some of them had problems with the bundled cooler not being sufficient, such as this one:
https://www.amazon.com/Corsair-Hydro-Performance-Liquid-Cooler/dp/B00B4OCW7K

You should however keep in mind that most people are overclocking that chip to 4.6, 4.7 so if that is not what you are running you should be good to go with that asetek unit.

okay, ill get a 240mm this week at some time this week, i just didn't think it would be my CPU overheating as i have had the TX3 as the cooling for almost 3 years. ill put another post if it doesn't fix the problem but it probs will.

thank you all for the help.

just wondering what is the default voltage for a FX 9370 as i downloaded AOD and it said the voltage was at 1.47, im just checking becasue that just seemed high as i have never even bothered trying to overclock it.
