New to PC, need advice

jamezz23 · Jul 9, 2017

Okay here the down low, I just got back into PC gaming, never was too smart with internals and whatever that goes into building one, so I just bought a pre-built one, I know, I know, but it is what it is.

What I bought was an iBuyPower BB931, its one of their higher end pre-built ones you can buy, its an i7 7700k, gtx 1080 GPU, with a MSI PC MATE (MS-7A72) motherboard, 16GB of ram, SSD, liquid cooled, and I got it for $1,500. So I started reading around on what temperatures are acceptable with the GPU and CPU and realized it runs pretty effing hot. Only had one exhaust fan out the back and no intake. So I added 2 intake fans from the front and one more exhaust out the top, now temperatures are lower, CPU peaks at 81, which that seems to be only for a milisecond, casue when ever I look at it its in the 40-60 range,, and the GPU is anywhere from 55-65 and thats right after an alt+tab to see where the temps are

So now where I am at is decent temps, but I started reading into undervolting the CPU, cause from what I read its over volted from the factory and you can reduce some volts without even sacrificing any horsepower, and achieve lower temps. When I start up CPUID within a few mins of idle, this is what I get, the volts shouldn't be that high at all, right, especially basically at idle? I am a novice so I need advice on how to under volt the CPU, I know how to get into the BIOS but from their everything starts to look wierd. Heres what I am talking about http://

First, you overpaid for your computer by 200$. Should have gone for a custom build.

Second your processor can run at a maximum of 100C. As for the intake, you don't need one unless you are trying to keep the mobo/RAMs cool, which doesn't seem to be the issue here. I suggest you flip the intake fan around so that it becomes an exhaust fan. Getting the hot air out is more important. Cold air (room temp) will automatically flow in again as suggested by Bernoulli's Equation and the Combined Gas Law in physics.

I don't see what the problem is in the image you have attached. 1.375 volts are perfect for you CPU. Over clockers go up to as much as 1.45v. CPU peaking at 81 is a bit high but nothing I would be worried about. My i5-7600k goes up there when under stress too.

What resolution are you running on? GTX 1080 GPU running at 40-60 is great. It goes up to 85C in FurMark stress tests. As long as you see these temperatures, you are good.

I suggest you don't make any changes.

That being said, I will still tell you how to change the volts. Since you have an MSI z270 motherboard, I recommend you download the MSI Command Center App from MSI's website. It'll be under support tab on your MSI motherboard's page along with other utilities and drivers.
Once you open MSI command center, click on advanced button and select "voltages". You can change your base clock, core ratios, voltages, DRAM frequency, etc.. using this. You can even control the fan speed and make them go faster once your CPU reaches a certain temperature or make them run at 100% speed at all times.

Let me know if you have more questions.

Good Luck!

Okay, I'll reverse the 2 intake fans as exhaust, I've already had good results but maybe flipping them around would be even better.

I was playing overwatch at 1080p at high settings, might not be the most demanding game but it should give a pretty good benchmark on the cooling setup you have.

The only reason I was thinking about under volting the CPU is just because I was under the impression you can turn it back a few notches, remain stable, maintain same system speed and reduce heat all at the same time. That by itself was what caught my attention

I downloaded the control center and I am still confused what area to edit it under volt it, maybe ill just forget about it if I cant find exactly what to do. I think the only one I would need to edit would be the core voltage which has a min/max range from .600-1.52

Maybe someone who has done this can give me a clue on where to start?

Overclocking is not my best field of knowledge unfortunately. But you are right core voltage is what you are looking for. I increase the clock speed to let my cpu reach ~4.8Ghz and don't mess with the voltages.

I suggest you wait until an expert in OC comes along. In the mean time you can research online for stable 7700k OC settings.

One important thing I forgot to ask: What CPU cooler are you using?! This should have been my first question lol. My bad.

Its no big deal, thanks for the help so far. I'm using the Asetek 550LC liquid cooler. I'll hang around so see if anyone has some experience doing this

If you don't find anyone, PM me and I'll start doing some research.

Okay cool. Theres a 60 page topic over on intels forum about the temp spikes and what they did to control it a little bit so ill be searching over there too!

Little instantaneous 'overshoot' spikes are of no consequence....

(I don't think a 7700K/1080 build at $1500 is very bad at all; no one builds/sells rigs just to break even, and, not everyone is either comfortable and/or adept at building them.)
