I'm looking to build a pc in 2 weeks time and I'd like to know what my system temperatures would be regarding the build above.
For example,
What would my CPU and GPU temps approximately be under idle and full load, while taking into account my systems airflow? I'm planning to place the cpu radiator at the front of the case pull in air and then being exhausted by the two 140mm fans above and the one 140mm at the back.
Would my gpu suffer as a result?

Thanks!

I would have to carefully watch the videos for the settings used.

What you see at the top there for CPU and GPU usage is somewhat informative with CPU usage and GPU usage. Seems like the first guy was letting the GPU run wild, but it was un-overclocked and at the stock 1835Mhz frequency, and likely default power settings, he likely turned the fans way up as well to keep temperature that low and/or he also had an exposed testbench rig, which is really ideal for axial cooled cards, no enclosure to trap in heat. So that can't be used as a fair comparison to a more traditional case.

Second guy was not running flat out from what I could tell. Either not setting the graphics details high enough or the resolution he was running at wasn't too...

Should be fine. This is more or less a let us know...

Ambient temperature, fan speeds, pump speeds, actual performance of the silicon on the GPU and CPU, their settings, overclocking, and the workload will all have an effect.

I could ballpark and say the CPU will be pretty cool, probably in the mid 60s under load. The GPU I can almost guarantee will peak at 83C, since that is the typical default throttle point. If you adjust the fan curve until it stays below 83C at a full load (if possible) then it should reach higher boost clocks, as long as you can tolerate the noise it makes.

The temperature of the hot air coming off a radiator into the case has a minimal impact on internal temperatures. As long as the air is moving through the case the system will have its cooling medium. (In my computer I have both an intake and exhaust with a radiator, the key is the surface area and airflow)

Ambient temp is 22C
Exhaust fans approx 1250
Pump speed average don't really know what that is
I'm not looking to overclock
Is my Gpu being the gigabyte gtx 1070ti g1 gaming good in terms of sustaining 55C - 70C temps under load in relation to the variables above?

Thanks

I don't keep a table of ambient temperatures and individual component and their settings to performance curves laying around. No one does.

Water coolers have pumps in them, that is how the coolant is moved around. You can set these speeds just as you can the fan speeds.

If you aren't overclocking, then not entirely sure the water cooler was a necessary investment. Ryzen chips also perform quite a bit better with a little memory overclocking, and adding a few hundred megahertz to the CPU while you are at it is easy enough. Can even use Ryzen Master to do it. Not a lot of effort to gain that performance.

It is nice when you can keep a GPU that cool, but it isn't common. They will boost up to the temperature limit set, then back off. All 1070Ti come exactly the same from the factory per Nvidia, so I suspect an 83C temperature limit is set. When needed it will reach that temperature regardless of cooling (unless cooling is more than sufficient, not typically the case with air cooled cards.)

And again, completely depends on the load.

Yeah, I've been looking at temp tests of my gpu on youtube and it usually sits around 60 C to 70 C across multiple videos. I don't know what to believe man. Anything above 70C seems too hot for me and I'm not looking to invest in a water cooling loop either. I don't know :??:
Take a look at these videos for example,

I live in a cold climate. Temperature currently is 7C - 13C

Second guy was not running flat out from what I could tell. Either not setting the graphics details high enough or the resolution he was running at wasn't too difficult for the card. So the GPU wasn't reaching a full load. In some of the games it looked like his CPU was the problem, but I didn't catch what CPU he was using. Also didn't see his computer I don't think. So again, not a fair comparison.

The card will protect itself from overheating. They are quite limited these days without hardware modifications. So the power limit and temperature limit have maximums. On my GTX1080 it will only let me set a 125% power limit and a 92C limit as I recall. On the power front I certainly get up there, but I am running at 2100Mhz, but temperature I haven't really exceeded 60C (Which is what water cooling gets you)

GTX1070Ti is a bit unique in that the AIB partners aren't allowed to include factory overclocks, or bin the chips(maybe?), so how well your card runs at lower voltages is really luck of the draw. Every card will be a little different in how it responds to its power targets and temperature curves. (Which you can modify up to a point)
