Will my cooling survive this upgrade?

[JohanKjeldahl7]

Hey everyone, sorry this is a longer one.

 

I currently have a beQuiet Pure Base 500 without the glass side panel and only the dust filter (NOT the sound filter) on top.

I run an intel i7-8700 + GTX 1060 6 GB with the beQuiet Power 9 500W PSU. The CPU is cooled by the beQuiet slim Rock 2. Currently there is no cooling problem of course.

I am upgrading to an RTX 3070 (don't know which one but it will be Triple slot and triple fan) and to a beQuiet Straight Power 11 850W PSU.

With the upgrade the CPU will of course run at a higher wattage and will run hotter.

 

 

So my Question is:

Will my CPU cooler be enough? Will my case cooling be enough?

 

Budget isn't the biggest problem (I can sell my case to my sister which needs one anyway and I have some more cash set aside for the upgrade), so a better airflow case or a AIO cooler or similar wouldn't be the biggest issue but I would like to prevent any further cost if possible of course.

 

Thanks in advance, and sorry again that my question is rather long.

 

My current case cooling: 4x 120mm beQuiet silent wings 3, all of them PMW 4 connected to a fan splitter.

Seems fine, from what i have seen both the 1060 6gb and 3070 consume about 200 watts, so unless you heavily oc the gpu, the heat produced will be the same, so nothing to worry about, it isn't a 3090ti.

The 3070 (non ti) would work fine with your 500w psu too most likely.

Should have mentioned: The GPU will only receive an OC if it is like the "OC" version from the company. Overclocking scary ':( 

Will the 3070 really only consume 200W while gaming? I play at 1440p and will probably turn RTX on from time to time as soon as The Witcher 3 updates.

Yes, even with RTX on. You can look at Gamersnexus review on youtube, he has timestamps, so you can jump to power draw.

It is expected for new gpus to be more efficient than old ones.

Ok that is very good news. Thank you!

 

One more thing if you don't mind: Would you say the PSU upgrade is useless in that case? The CPU will draw more power with the 3070 but will it need more than a 500W PSU to run stable? MAybe 850 is a biiiit overkill.

I assume you have the non overclockable i7-8700 non K, and unless your motherboard does weird things to it, it should run at 65 watts.

So 65+250=315, so it seems to be in the safe 80% of the psu max, even with a ton of harddrives, and maybe a bit lf cpu turbo.

I personally wouldn't upgrade the psu, but if you want the psu to be quieter and maybe to be able to take a 3090 in the future, then 850w maybe justified.

What model is your PSU? A good 500W PSU will be sufficient for your upgrade, a budget one will not be.

 

Also, if you run into any thermal issues, I would move your top exhaust fan to be a third front intake fan.

 

Oh, and your CPU cooler will not need to be upgraded.

Alright, thank you very much!

Yes, it is the non K version of 8700.

It is the beQuiet Power System 9 500W (non modular, was on a small budget back then).

Bequiet system power 9 should be decent enough, especially because it won't be near 100% load.

Agree with moving the top fan, hot air rises to the top anyways, so the fan could be used to supply fresh air to the gpu.

3 intake fans seems like an interesting idea, since my PC is directly in front of a wall anyway, the back exhaust fan is just straight blowing against a wall... Thanks for the idea!

Yeah, it's not great. Double Forward primary with passive rectification, but DC-DC secondary so that's good.

 

It's worth a shot. Only replace it if it gives you trouble.

[DoctorNick]

@JohanKjeldahl7If you can try 3 fans in the front and one in the back, maybe even with the sound filter installed. Positive pressure is the way to go.

I'll try it out for sure, thank you very much!

I'll have to search for the sound filter but if I can find it I will make sure to give it a try and compare the results. But I will 100% go with the 3x intake since so many suggest it. Thank you!

Nvidia says 650 for the 3070 no?

 

FWIW my 3070 Ti and “105w” CPU can do 640w at the wall.

I thought so too. Also beQuiet recommends at least 650 as the bare minimum for my system but suggests 750-850 as a save and energy efficient/more silent option.

No, they say 550w. FYI, the 3070ti has a far worse power draw at stock, it has a 300w power draw, instead of 220w of the 3070. And to top it off, you have overclocked it as well.

Also you have PBO on the cpu, so no wonder your cpu uses up to 140w instead of the default 105w. 

You also have to account that PSUs don't advertise the amount they pull from the wall, but instead the power that they can supply the components. 80+ efficinecy and all that.

so your real power draw to the psu would be closer to 640*0.8 = 512, which seems fine for both an overclocked CPU and GPU.

 

Your FWIW is quite meaningless without those facts, and you didn't provide them.

 

3070 and i7 8700 would be fine with a 500w psu, but i understand that the op wants to put it in the system for his sister.

[freeagent]

My CPU does over 200w, much more than 140.

"I only see your reply if you @ me."

 

But interesting. I thought it would do 140w, because that is what the am4 socket limit is, but I guess you can easily go over it with a tweaked PBO.

Yes, about 210w, 236wPPT.

You can get the 500dx mesh front panel from Be Quiet directly. Should cost about 25-35€ shipped.

[Ralfi]

I don’t like the case (front) as it won’t allow as much fresh air in as much as a full mesh front would.

 

But to minimise costs for now, & if you’re happy with those existing fans, add two more: 1 to the front-lower, 1 to the top-front (to assist your restricted front airflow) & see how you go.

 

I recently tested 1-3 front fans, & it resulted in cooler motherboard temps & to a lesser extent, reduced CPU/GPU temps, & that was in an airflow-focussed case.

Thats a really interesting idea, I actually thought about that case as an alternative for better cooling so maybe I'll actually go that route. Thank you!

I will go with 3x intake in the front right now I have decided (I found an extra silent wing in my drawer, I have no idea where it came from but I am not complaining). Thank you for testing such things for the community, that must have taken some work!
