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_detailpage_o01_s00?ie=UTF8&psc=1.
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

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.

@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.

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?

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.

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.

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.

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.
