Hi,

I recently purchased a 270x to compliment my already running 7870 OC to run in crossfire mode.

When initially running the configuration I noticed that at idle the cards were running at 50 degrees.

I started to run a few games, e.g., Grid AutoSport and Alien Isolation, and noticed the temperatures in Trixx going to 99 degrees.

I was a little worried so I decided to take one of my internal case fans and mount it to the wire mesh on the side panel. This instantly reduced the temperature by 20 degrees.

I've just purchased three NoiseBlocker B12-4's to mount into the front and rear of the case, and replace\run a long side my current side panel fan. Hopefully this will reduce the temperature a little more.

Now here is my question; Is it possible to get a standard height VGA cooler to un on my crossfire cards? The reason I say this is, the two cards are running side by side, and I mean that there is about 1-2mm of space between the two cards, so no room for massive coolers.

Does anyone have any ideas, as all the fans and heat sinks are much taller than the stock versions? I really want to get this system back into the 60's again.

Furthermore is it possible to just replace the fans on the VGA cards? And does changing the heat sink compound make much of a difference?

Current set up;
Asus Sabertooth 990FX
MSI 270X Twin Frozr
Sapphire 7870 OC

Thank you all.

70-80C is a great temp range for CFX setup, as they're usually hotter than the ever hot AMD, usually in 80s. But yours, at late 70Cs is good enough. Hoping for 60C is a bit impractical, and 80C doesn't really do any bad anyways. Adding case fans will help a bit too, and opting for af VGA cooler may lower them further, but unless you want to OC substancially, it's of no use over current temps.
Changing thermal compound makes a difference with old cards (I mean cards which have been used for more than couple of years), and cleaning dust off the card is as important.

Thanks for the response MeteorsRaining, I don't feel as bad as I originally did with the temperatures rising.

I am still looking for a VGA cooling solution, but other than water cooling I have not been able to find anything that will fit due to the nature of the two cards being so close to each other.

The three extra fans are yet to arrive, but I am hoping today is the day. I'll let you know if the these make any difference to the temperatures.

Thanks again.

Water cooling is usually the only way out if space is an issue, but you shouldn't have to worry if your temps w/ 3 more fans reduce quite a bit. Let me know, good luck.
