i am at the end of my rope...i was finally able to get another R9 290 so now i could crossfire. they are both gigabyte versions GV-R929OC-4GD and i have tried every Fan combo i can think of and no matter what card i have on time it get HOT and by HOT i mean this whole pc was pumping out so much heat that my air conditioner couldn't keep up lol. I am looking to see if i could water cool the top card if anyone could point me to the right direction it would be great. This is the kind of case i have http://www.amazon.com/gp/product/B00FL3Q9I8/ref=oh_aui_....
with an
AMD 8320 CPU Cooled with the corsair H100I
16 gigs of corsair memory
750 watt powersupply
ASUS M5A99FX PRO R2.0 Socket AM3+ 990FX ATX AMD MoBO
Got so bad i had to take a card out so it wouldn't get so hot. Please HELP!!!!

My laptop uses to overheat severely as well, just take it apart and clean out the Dust within the cooling fan, it fixed my problem :wahoo: . Hope this helps

What temps are you actually getting?

Even a perfectly normal GPU will make ALOT of heat. Without knowing your temps we can't even tell if the card is running hot or not.

The problem with spending much money to fix your problem such as going liquid cooling is that you might be better off trying to SELL your cards and go NVidia.

1) As you may know by now you can get a GTX970 4GB card for $330 USD which not only runs incredibly cool and quiet but it also beats your performance.

If you could get at least $250 per card it might be worth considering. Personally, if you do get the GTX970 I recommend the Asus Strix version at $345. It even has a 0dB mode so they will make absolutely ZERO NOISE during idle or light gaming. They generate about 9Watts of heat in idle.

2) You can't reduce the HEAT OUTPUT of your computer without down-clocking the graphics cards. You can cool the temperature of the cards themselves but that will have absolutely no affect on the heat output of the computer.

3) If you want to reduce the temperature of the cards (again no affect on heat output) you really can only down-clock each card by say 100MHz or so. You already have a liquid cooler so the CPU heat isn't going into the case but if you need more air flow you should ensure front case fans as intake (which you likely have) and optionally get a case with a large SIDE FAN which can blow over the cards.

There is no wayto even tell if OP has an issue or not as we don;t know the GPU temps. Chances are everything is perfectly in spec. A card running at 80c (perfectly safe) will generate ALOT of heat. My 660ti's heat my room right up when they sit at 75.

The fact that they have WINDFORCE coolers tell me that they are just fine. Those cards have amazing coolers

@dreemz i just got both of these cards about a month apart so no dust.
@ Tiny Voices which ever one i have as the bottom card stays 75 to 80C at full load now the TOP card that thing goes to like 94c saw it down clocking to stay at that but at one point it went above 95c even had the PC shut down on me when it did.
@ Master Dell ...LOL thanks
@ PhotoBoy...I wouldn't mind trying the water cooling...as a bit of a project like hey i spent the money getting these cards might as well go for the gold ya know.

Try upping the fan speed on the top card.

Update:

The HEAT OUTPUT is a combination of both the AMD CPU and the AMD graphics cards is massive.

According to Techpowerup, a card like the Sapphire R9-290 OC uses just over 100Watts more than a stock GTX970 while still getting lower performance. If we double that (two cards) and if you overclock the FX-8320 CPU as well (extra 150Watts versus Intel) it's significant.

I compared the two setups:
#1: i5-4690K @stock + 2xGTX970 (reference), and

#2: FX-8320 @4.5GHz + 2xR9-290 (Sapphire OC)

The first is NOT overclocked, while the second IS overclocked not to be unfair but because the first at stock speeds still comes ahead and this article is about reducing HEAT OUTPUT (I know a completely new system is not an option).

The second system uses about 350Watts more power which all goes out as heat!! That's roughly 100W per card and 150W extra for the overclocked AMD CPU system.

The Intel setup uses roughly 460Watts under full load, whereas the AMD setup uses about 810Watts under load. Consider the heat output of just a 60W bulb and that's a lot of heat.

I don't have the IDLE specifications handy though I'd guess about 70Watts for the Intel and perhaps 100Watts for the FX-8320@4.5GHz system (2xGTX970 and 2xR9-290 setup respectively).

*Ways to reduce heat of AMD system:
a) downclock the CPU
b) downclock the GPU (and perhaps the VRAM)
c) sell the AMD cards and buy GTX970's

Dropping from 4.5GHz to 4GHz will save perhaps 50Watts of power (I forget exactly) and swapping cards will save about 200Watts.

Do what you will with this information but I see these as the only real choices. Again, cooling your cards better has no bearing on the heat output of the system (aside from any fan or pump power added).

I believe whats going on is that the heat from card number 2 going from the bottom up is affecting card number 1 with all that heat which makes the GPU core temp go up.
@ Photonboy i can't give up on these cards yet so i am going to look at down clocking from 1040 to like 900 i think those are what the none OC's have.
I do have another question would the added heat come from my PSU since its 750 Bronze cause i have read that these cards might need a minimum 1000 watt power supply?

I say swap the first card with the second card. See what temps you get

no matter what card is on top the temp on the top card is always wayyy to high cause of the massive heat these guy give out. Thats why i said if there would be a liquid cooling solution so that i would have that top card temps to stay resonable. If they are by themselves the card stays at really good temps but if they are both in the case at the same time that when the top card temps are through the roof. the CPU is not over clocked and its cooled by the Corsair h100i. so basically no heat from that thing its all the vid cards that are pumping out all the heat either my fan setup is wrong or something. Ill post a picture of what it looks like inside.

Maybe try putting PSU fan side up and switching the newest car to the top because it should have better cooling

I wouldn't do that. Then the fan on the PSU will be taking hot air from the GPUs. You want to leave it fan down so it can get cool air and be its own enclosed system.

Fair enough. I would do it because I would sacrifice PSU life for card life. Cards are triple what a psu costs

i have a fan at the botton taking out hot air...gonna test it soon...so 2 intakes in the front 2 fans exhaust from the top one fan in back bringing in cool air and 2 small fans right on the heat sinks on the card that came with the tower.

But when a PSU fails it can fry the entire system.

I would try removing the side fans. Sometimes they can do more harm then good. They just mess up airflow. In my case with my dual GPUs, I get higher temps WITH a side fan.

The fans should be front/bottom = intake and rear/top = exhaust. Make sure your setup follows these rules.

now the bottom for intake is pretty interesting cause it is right on the 3 fans for the windforce wouldn't that negate the single fan pumping air in from the bottom because those fans and blow air down hardcore.

The fans on ANY GPU blow air towards the card, not down. The bottom fan should ALWAYS be an intake ALWAYS. With it as an exhaust you are stealing air from the GPUs.

well i was able to do it...i got the water cooling for the gpu and it runs at a cool 70c not an insane 95c now all i need to do is do the same to the other card and all is well thanks for the advice.

What PSU did you go with?

What watercooling setup are you using? 70c is quite hot for water cooling and honestly sounds like something is wrong. It should be in the low-mid 50s at max load. It sounds like you plain and simple have a defective card. A properly watercooled 290x usually never goes above 53c at stock clocks.

Your card has issues.

That's why I was saying switch the places of the cards to see if it still runs hot.. But no one listened so idec :)

i could of sworn i put down somewhere in the thread that no matter what card is on top the card on the Top is the hotter card...cause its getting the heat from the bottom card. the power supply that i got was Cougar 1000CMX Power Supply . I would have to say i think its the way the case is with the fans i think i need more powerful fans to get the air going.

I went with the H55i and the Kraken 10 for one of the 290s. it works wonders

September 27, 2014 4:35:44 PM

Oh ok, yeah those high temps make sense then. The h55 is a poor water cooler and for CPUs is beaten by $20 air coolers. On proper watercooling the GPU should sit in the 50s. I have seen alot of people with h55 issues when using the G10.

Also, you have heatsinks on the VRMs right?

just got those bad boys today...gonna put them on i acually had been monitoring the vram temps they stay pretty low from what i have read they don't go any higher then 95c on the water cooled one but i have to put those heat sinks on just in case. only reason i got the h55 was cause it was a test run just in case i messed something up didn't spend that much money

Best solution

September 27, 2014 5:00:37 PM

95c is HOT for the VRMs. Hopefully you have not done any damage to the GPU running it without VRM heatsinks.

The best solution is an L bracket. It goes flat side down above the lower card and the high side goes up past the upper card. This has a net affect of separating the air draw of the 2 cards. Put a fan blowing down the length of the upper card, lower intake feeds the lower card. Leave about an inch of space from the bracket upright to the upper card.
It mat not be pretty, but it works, allows all sources of heat a vertical rise, and maintains separation of draw.

It's not a new idea. It's called a chimney.
