So we both agree, Gigabyte cards have shit fans and people should avoid them. Easy, to understand, right?

you missed my point i never said that they were good, just that you can avoid their problems by adding additional fan so they can run at lower speed

but this is not true in winter where you can leave them at lower speed regardless, it wasn't so hard to understand....

It's the same shit dude. Changing room temperature is quite a bit different then trying to assist the coolers. You're trying to change the subject to wiggle out of this because you know exactly how wrong you are. You literally have extra fans on your GPUS, whether pointed through the front or on the top to keep the fans at lower speeds, you said so yourself 'so they last longer', because the fans are broken. That is also why you have your fans permanently set at 40%.

This has nothing to do with room ambient temperature and there is absolutely no way you can change room temperature with a little 140mm fan. I have high flow large radius fans going in and out of the room, something in the range of 15,000CFM. For small operations people use box fans in and out of the room, those move once again about 3-4,000CFM. A 140mm fan moves roughly 150CFM. You would need 100 of those to get the same sort of flow I'm getting.  If the coolers were good you wouldn't need to do that.

Once again Gigabyte fans are absolute trash, they fail in 6-12 months without pampering them or babying them, including setting the speeds artificially low and cooling the cards with a different fan, taking them apart to oil them every couple months, or blowing them out every other month. You don't need to do that with any other video card manufacturer.

Pretty sure maxwell can't do more on xmr.

1070 can do more than 600, need to play with settings & os.

yeah and a 1070 can only do 600h, something clearly wrong there

Yes you can push them to 22-23, 240-250 and 520-530. But there is no need for that when they do 500 so silently.

you could squeeze 21.7 on ethash / 230-40 on equihash with 970...
I didn't know the xmr score though

Went to whattomine with 970, current revenue & difficulty. 20 on ethash, 500 on cryptonight, 200 on equihash. Cryptonight came on top of that listing, I never believed this day would come.

no not on top, on the front, you know by creating the tunnel effect, without that and 30° celsius on the room it's not possible to have good temp(below 65-70°) with only the gpu fan

I've been mining for more then three years dude. Yes I've had a couple summers. You're talking about putting 140mm fans on top of the cards to 'keep them cool'. Fans moving air in and out of the room keeps the room cool, not specifically the GPUs. If you're just keeping the GPUs cool, you don't get rid of excess heat and it builds up in your server room.

The GPUs should be able to maintain their own temperature or they aren't doing their job. That's specifically one of the reasons for buying one brand over another, the cooler.

Yes and I have a power meter on my one rig that helps me out a lot to see the power draw to cost of electricity to the going price of the coin I'm mining.
A power meter is a must to me.

Sp thx for the trust rating against this scammer.

you have additional fans...he was talking about using only the fan of the gpu


well "moving fan in and out" is the same as additional fan.... it prove that the fan alone of the gpu are not enough especially in summer at 30° did you test it ?

in winter the thing is different, there is no problem even if i live my gpu spinning without additional fan and at 40% i get good temp

Sure, room circulation is one thing... If you need to throw a bunch of fans on top you're doing something wrong. Try spacing things out better.


Your GPU gets hot, good fans cool it though. I have about 1 1/2 inches between each GPU and eight above each rack. I don't need extra fans besides moving air in and out of the room.

The insult was at the end of the response where you're trying to justify adding extra fans to your GPUs because the fans on the GPUs suck makes the fans on the GPUs good. If you have to add extra fans in the first place to prevent the fans on the GPUs from failing, they're basically already broken. No other manufacturers have this problem besides PNY and XFX, all of which use the same half-height low profile fans.


Haven't had fan failures on those yet, but I'm sure they'll be coming up shortly.

The best result i have with gtx 1070 gigabyte OC 2x , have samsung memory and overclock + 800 or plus mhz at Power Limit to 50% :



.

Exactly

@amph: that's why it's important a deep study of the ventilation, and forced flows. In my solutions with 6x vga configs, with 32°C of ambient temperature, I hadn't any problem even with 7990s. 150W tdp cards are an easy thing to manage there, plug&play

Haha. Precisely

no i didn't bought those for that reason, but because of summer, and in summer no matter at what speed you put your fan it will get to hot for your gpu, already tested

you need a tunnel effect at 30°, btw insulting don't make your argument more valid, actually it make it more irrelevant and trolling

For best cooling (most efficient and better at preserving the hardware) you need multiple layers of fans.
Fans on the card, fans blowing air on the cards, fans blowing fresh air into the room (or pumping hot air out), etc.
You need to find the best balance of them, and the power meter is your friend.

Sorry people off topic but do you believe this guy?

Keeping it cool? If your fans weren't there, the fans on the card would run faster. You bought fans to offset the fact that the fans on the card are garbage and you don't want to have to RMA them.

The point is the fans are garbage and you can simply buy a different model of cards and 'easily avoid the problem', also save electricity you are so keen about in addition to not having to buy extra fans. Wow, it's like a triple win... We could also add in there manpower and time in addition to the fans inevitably failing anyways, just taking longer (15 months?).

If I were to recommend cards for someone I wouldn't go 'oh hey you should buy these awesome Gigabyte 1070s, just make sure you buy three extra 140mm fans to help cool the cards, manually set the fan speeds on the card to 40% which you may need to change on all your rigs in the future if they use more energy, get hotter, and ambient temp changes, oh and those fans will more then likely fail anyway and your whole system will use more power all the while this is happening hehuk'.

You're really a dumbass sometimes.
