I recently purchased a second Sapphire 4890 to crossfire with my first card, however, I really don't like the cooler on the newer card. The temperatures run much hotter on the memory, and it doesn't exhaust air out the back of my case.

Does anyone have a stock 4890 cooler they aren't using they would be willing to part with? (Or know where I could get one?)

Sapphire generally does very well with aftermarket cooling, assuming you have the vapor-x edition. If its only your ram that's getting too hot, you could look into putting heat sinks on them. They're pretty cheap: http://www.newegg.com/Product/Product.aspx?Item=N82E16835185083

Beware though, I don't know too much about the dimensions and the free space available under the cooler so make sure you have room to put them on before you purchase.

You're probably going to be out of luck if you're looking to purchase a stock cooler. Nvidia and Ati generally don't sell their cooler to retail outlets.

If you can't find a second hand stock cooler, newegg has a bunch vga coolers: http://www.newegg.com/Store/SubCategory.aspx?SubCategory=576&name=VGA-Cooling

Good luck!

Hmm, it looks like sapphire already adds heatsinks to ram: http://www.newegg.com/Product/ImageGallery.aspx?CurImage=14-102-848-TS&ISList=14-102-848-S01%2c14-102-848-S02%2c14-102-848-S03%2c14-102-848-S04%2c14-102-848-S05%2c14-102-848-S06&S7ImageFlag=1&Item=N82E16814102848&Depa=0&WaterMark=1&Description=SAPPHIRE%20Vapor-X%20100269VXLE%20Radeon%20HD%204890%201GB%20256-bit%20GDDR5%20PCI%20Express%202.0%20x16%20HDCP%20Ready%20CrossFire%20Supported%20Video%20Card

They looks kind of small though, replacing them may work. If not, try to find a cooler that suits your needs

edit: You can see some of ram on the third picture in the link provided. They're in the gap between the fan and that big sapphire logo.

I have this version, not the Vapor-X:

http://www.newegg.com/Product/Product.aspx?Item=N82E16814102852

There are heat sinks on the fans, but they do not cool as well as the stock cooler, which I believe has the cooling block in contact with the ram in addition to the main proccessing area. Using Everest, I read the temperatures on the Ram of my 2nd card more than 5C to 10C higher than that of the ram on the card with the reference cooler.

I know some people have put aftermarket coolers on their card, I was hoping I could snag their original cooler. I can get temps down by cranking up the fan on the newer card, so it isn't the end of the world, but it does limit my overclock a bit.
 
I had tried to Crossfire (2) 4870's and had terrible heat issues. They were the ASUS Dark Knight versions and the bottom card ran fine but the top card trapped the heat from the card underneath and would hit 100C in Crysis and would crash the ATI drivers. The motherboard I have didn't leave much space between the two cards, but some have that extra 1 slot between then which would have probably been MUCH better for me. You can always get a 120mm fan and zip tie it to circulate air under the top card. I ended up selling both cards and getting a single 5870. BEST choice I made.

So your original card uses the stock cooler? You can always try switching the cards to see if it circulated air better. Like if the OEM cooled one is on the bottom, move it to the top to see if it blows the hot air out, or vice versa.

My motherboard actually has lots of room between the cards, and it works out quite well. I have the original card as the lower card, because the intake on the original cooler is far enough back it is past my sound card.

It is pretty interesting to use Everest to graph the differences in temperature between the two cards. The fan on the newer card is quieter at the same speed, but to get the same cooling performance it actually needs to be 30% higher than the reference cooler design. So, at about a 10% overclock, I have the reference cooler at 40%, and the new version at 70%.

Awesome, I'm glad it works out! To mad mine didn't :-\

Good thing I grabbed the 5870 when I did, they are starting to jack prices. There is a VisionTek on Newegg for $410. I'm sure the others will follow.
 
^ Yeah it does and it was the best choice for me I guess. My Crossfire setup just didn't work out and I wasn't going to go through the pain of rigging some cooling solution either. I figure I sold the two 4870's while I could still get some money for them and put that toward the 5870. I am happy now.

I DO know that the crossfire setup rocks some hot totty though. I was able to run some games for a little while until things overheated and I was really happy with the performance. Just the heat drove me up a wall.
