I have a 7870xt and a 7950,now here's the problem,the card that is in the top PCI-E x16 slot always gets extreme temperatures.(Tried with both,the one on top always gets to 90-100 degrees celcius,while the bottom one stays cool at 75 max.)
I have a CoolerMaster HAF X tower,and have tried everything,but the temperature won't go down.
Anybody can suggest something other than watercooling?WC is too expensive and advanced for me,so I'd prefer fan cooling advice.
I recently ordered a Bitfenix Spectre Pro 200mm fan to add to the top,and a Spectre Pro 230mm fan to replace the front,will it suffice?
(Sorry if it seems like I'm invading the thread,hopefully any advice given should help the OP as well)

P.S. Noise is not an issue.
lay the case on it's side rather than standing up, and keep the side panel off.
I already have the side panel off,will it being on its side help that much?
I also forgot to mention that I have the rear fan turned the opposite way so it blows cold air rather than expel it,and have done the same with the top fan as well.

yes being on it's side makes a big difference, heat rises.

You should have the rear and top fans blowing out, you want fresh air drawn in from the front, exchanged over the heatsinks, and then blown out of the case.

If all the fans face in, you're just going to be turning it into an oven.

I just installed my water cooler at lunch today.  I have a 7970, with a Antec 920 (I believe the Antec 20 would have been enough).  Using 50Miner I'm getting 680 MH/s  @ 54 C.  Once I burn this in I'm going to switch it over to LTC using CGMiner directly.  The current limitation is the miner interface.  I do believe if I was using CGMiner directly I could get the GPU over clocked even more.

To that end the radiator doesn't fit in my box so it sits next to it.  Cosmetically, not so nice, but then I'm a guy I don't care.  It works.

I'm curious how you installed the 920 on your video card since it's designed for CPU cooling, not video cards.
