7970 Crossfire temps are bizzare, top card hits 88C in assetto corsa 1.0 RC, looking for a cooling solution that wont kill my wallet.

EDIT: at the time of the 88C temp i also had a box fan next to my PC with the side panel off running on max.

System:
CPU: AMD Phenom II x6 1045T @ 3.5Ghz
Motherboard: AsRock 990FX Fatal1ty KILLER
PSU: XFX Pro 850W Black Edition
Memory: 16GB Patriot Viper 3 1600 CL9
Graphics: 2x 7970 Double D in Crossfire
HDD's: 2x WD Green 1TB 1x Toshiba 2TB (SSD Soon)
Cooling: Antec H2O 620 Liquid Cooler (Push Pull)
6x Generic 120mm Blue LED fans

How close is the bottom video card to the top one? If there is insufficient air flow your top video card will run much hotter. You also have to remember heat rises so the top card will always be a little warmer than the bottom card.

Ambient case cooling is your cheapest bet. The top card is getting all the heat from the bottom card. Make sure you have your case well ventilated. Interestingly, you have a closed loop liquid cooler on your CPU, which should bring down your case temps substantially, unless you misdirected the fan to blow back into the case or something lol.

Buy some more powerful case cooling fans and slot coolers that can blow directly on the cards to help cool them. I have the same setup and I needed to buy case fans with high air CFM, a closed loop liquid cooler for my CPU AND use MSI Afterburner to adjust the fan profiles for the cards.

Summary:

1) Investigate purchasing much higher air CFM fans taking noise into account (delta fans will make you want to rip your ears off)
2) Purchase a good slot cooler that can blow directly on the cards, these can be found at frozencpu.com and other places
3) Download MSI Afterburner and adjust the fans on the cards to increase speed at a much sharper level as heat rises and max them out early as temperature grows.

One last thing, don't buy plastic/steel cases. They may be popular and cool looking, but they suck for ambient temperatures. An all aluminium case from either Lian Li or Silverstone should be standard with any enthusiast gaming build.

Look into the NZXT G10 bracket and something like a corsair H55 liquid cooler.

I believe he has the liquid cooler for the CPU already. I would do as suggested above and check the CFM on the generic case fans. You want some serious airflow through that case to help cool it down and make sure your case isn't on shaggy carpet in a hot room. If your room temps are like 80F, then it will obviously have some trouble cooling.

Then go find a cheap slot cooler.

at the time of the 88C occurance the room temp couldn't have been above 70F, both GPU's were at 100% fan speed and the box fan next to the case was maxed aswell. i understand the gpu on top will get hot but it seems a bit rediculous tbh even for 7970 crossfire, the two cards are fairly spread apart too, im looking at the Corsair 750D, but curious if that will help GPU temps at all, thats really all im concerned about at the moment. another thing to take note of is these cards are not overclocked at all, and arent even the black editions.
i've looked into the artic accelero 7970 cooler, but im just not sure how much that will help, im just trying to avoid a custom loop, already got too much money in this thing for my own good. haha

Holy Mother, just realized i havent put my 850w in yet, still on CX600M, do you think that could be the cause of GPU heat? i've heard low voltage on the 12V rail can cause un-intended heat, due to throwing off the voltage regulators on the cards. going to pop the 850 in tommarow, but out of curiosity could that be the problem?

One thing to think of as a side note is how you place your pc and if it is in the best spot of the room to get cool fresh air.

I'm talking about applying a closed loop cooler to the video card. I know he already has a liquid cooler for his CPU.

now see what i dont get though, is how is it normal for the card to hit 88-90+ with the gpu fans at 100% and alternate fans on them aswell.. even with one card the single card hits 90+ in furmark, i know furmark is crazy but in assetto corsa for less than 5 minutes or any game for that matter the card is hitting 85+, just bizzare, about to put my 7850 back in and sell these junk cards.

EDIT: Also, i would grab another CLC for the GPU but im running crossfire and 3 CLCs would be bizzare

Yep, click the partpicker link in my signature, and the partpicker link in the description. Exactly what I had to do to get a pair of 580s in SLI.

I have actually seen a few people do it intentionally from the start. Best I saw had one GPU at the rear as exhaust, CPU 240mm radiator as top exhaust, and the other at the bottom intake. I believe it was H100i, and two H60.
