Graphics Cooling Help

[DalekSec]

Need some help here.....

 

My 980ti gets to hot when playing newer games, eg on overwatch its 83C (i know this is in beta but still)

 

With Nvidia announcing the 1080 i am thinking of upgrading to those but still not sure how well those will cool...

 

So see the options in the poll!

still not sure how well those will cool...

 

... after two generations of NVIDIA GeForce cards, NVIDIA has finally built the updated version of the NVTTM design that features a bold and aggressive look. Designed with the same magnesium alloy metal used on the original cooler, the GTX 1080 cooler design takes things ahead with better cooling and acoustics.

 

This solution incorporates a new industrial design with advanced vapor chamber cooling that manages temps of 67°C in gaming at an insane overclocks of up to 2.1 GHz.

Wait for benchmarks. 1080 is looking faster than 980Ti with greatly reduced power consumption, but whether the speed increase will be worth the spend for you is another matter. If yours is getting too hot, give it a good clean and have a look at your case cooling design.

I upgraded my case last month, a lot better at cooling, apart from watercooling there isnt much more i can do if anything. As for cleaning its as clean as it can be

I don't think 83 is too high but have you checked your thermal paste ?

Closed loop watercooler? Depends how expensive and complex you want to go.

I think full on watercooling will be the last thing I be, not 100% confident on building it and don't want to keep changing cooling blocks. Might aswell leave it to my build is done and then watercooling as final touch.

Just removing the stock heatsink, cleaning and applying a thin (rather than the wedge the seem to come with) layer of paste before replacing it usually sorts out any heat problems I have with mine.

I've never taken the fan off of a ghx card, (always a bit scared due to how much it cost!) I've brought 3 fans to add better exhaust to my case. If its still to hot for my liking I will try this

There will be a youtube video of someone doing it I've no doubt. Might easy your fears or at least warn if you if its not an option and they've done something like glued it to the ram chips!

Before you spend more money, we need to look at you're case cooling first and also let us know the exact model of card so I can look at the stock cooler. Rig photos would be useful. As someone who has 3 x Radeon R290s that run at about 50 degrees under load (watercooling) I think I can probably help!!!

Hokey so...

 

Case NZXT H440

 

3 intake fans on front

1 intake on the back (this is the CPU cooler, corsair h55)

1 outtake on the top (soon to be 3 as I've ordered some coming today)

Your CPU cooler should be blowing out the case not in, or your blowing hot air into a hot case. Also remember your PSU probably have an out fan as well! So you might have hot air going out your PSu then being pushed back in with your CPU fan.

 

Think of the general principles, cold air in through the front, then expel all the hot air out the back. So your front fans are fine, its your back that need addressing.

I fully understand the airflow, but this cooler says it needs to be an intake fan, no way around it or my CPU goes pop!

 

My psu has a fan but only uses it under high load, plus its encased in its own little box and is unaffected by any other air flow

I wouldn't upgrade to a 1080 just yet if you already have a 980ti, wait for the 1080ti (assuming its coming) and try to improve cooling in the meantime if your worried about it.... 83C isn't all that hot, mine used to run 79/81C on stock.

I think i'm just slightly nervous of temperature due to how much I paid for the card, suppose the bright side of it is if it does blow I have a decent reason to get a new 1080!

 

I will stick these fans in later and see how it goes.

[Achandler]

Then your 3 exhaust fans on the top should solve your problem, at the moment you simple have to much air going in and not enough coming out so the fans probably aren't getting that much air flow.

The max temp for the 980 Ti is 92°C. Graphics cards normally run hotter than CPUs do so I wouldn't worry too much.

 

CPUs and GPUs usually thermally throttle themselves if they get too hot to prevent the chips burning.

They all say that, because realistically, air outside the case is cooler than air inside the case. However. The difference is usually negligible and doesn't really matter when you start measuring temperatures. I used to run my old H60 as an exhaust* and never had an issue, due to the aforementioned result that having it as an intake pulls hot air into the case. This can reduce the efficiency of other cooling components, especially a GPU like yours that doesn't push air out of the back of the case but instead circulates the air inside it (compared to, say, the 980Ti's reference design that exhausts air out of the back).. Realistically again this won't impact temperatures too dramatically, but there will still be an effect.

 

For best airflow, I make sure my case has negative pressure. That is to say, more exhaust fans than intake fans. I find it gives better results, but it's debated back-and-forth all over the internet so I can't really say it's making a difference, it's just a design I've stuck with and it always does the job. Positive pressure = more dust, which we all hate. With a GPU cooler like yours you need to get that air out of the case. The GPU cooler you have is designed to get more air through more fins on the cooler, and this will cool it down better, but if you don't have anywhere for that air to go, you're just circulating warm air and gimping the cooling after ~10 mins.

 

*My current H100i GTX is configured as an intake rather than an exhaust, but that's because there was nowhere else to put it.

Installed the 3 exhaust fans on the top, plus side much better air flow slighty cooler in case (plus it now glows red), downside my room is now a sauna when I play games.

 

I think I may go down said watercooling route

Vanity is the most important part of building a PC. I even have custom braided cables. There is absolutely zero reason for me to have them, except vanity. But they do look awesome

 

downside my room is now a sauna when I play games.

Which in turn means the air your pc intakes is going to be hotter and not cool your parts as good. You can't win! In all seriousness, though, it's better to have more airflow. Even if it does raise the external temperature, pushing more air through the radiators/cooling fins/whatever is always a good thing.

If you're not confident enough to build a custom loop, you can buy kits pre-made for graphics cards. EVGA and NZXT make them, I'm sure I heard something about Corsair coming out with a line of GPU closed-loop too.

You will still have to transfer the heat generated by your component's which will be the constant no mater if your using air or water & air.... fans will still be extracting the same amount heat out of your case.

Exactly! See: Newton's third law of thermodynamics. That energy (as heat) has to go somewhere, no matter what cooling system you have.

 

The point of watercooling isn't to reduce the overall heat your components generate, because that's not really possible, it's just to get that heat out quicker and more efficiently. The thermal conductivity of water/cooling fluid is greater than the thermal conductivity of air (for example, you can stick your hand in a 200°C oven and won't suffer a burn, so long as you don't touch any metal bits) and thus facilitates a larger transfer of heat over a fixed period of time.

 

Your room will still heat up just as much Consider opening a window.

Is that not what I said?

God Dammit Newton, it's bizarre as I'm sure it wasn't getting this hot last month, could of missed it as I was only really monitoring the CPU Temp and not the Ghx...

 

I'm also not sure how much of the heat was me! As I moved the modem yesterday so it was wall mounted and was drilling holes and climbing around up the eves for a good hour! Most work out I've don't since I was late to see Civil War

 

Edit: My room is in the Attic, which means I have 1 windows which when its open gets extremely windy (I do have it open a lot) but when it rains my Computer will get all the wrong kinds of water cooling...
