Overheating Crossfire 4850hd's, need advice on third party cooler?
HI, i built this sytem a couple years back but never used it for serious gaming, it has two radoen hd4850s crossfired, but i ve been having overheating problems with a couple simple sports games, nba 2k10 and mlb2k10, and crysis, i want to add two zalman vf1000's to each card, but i dont know if the one slot space between the two boards will be enough to house the first cards zalamn cooler, can anyone suggest a low profile cooler to put on them, thanks,
sell them and buy a 6870:
not worth it to run crossfire for around a 5850 worth of performance and no dx11, id sell those things on ebay and throw in a little extra money that you would have spent on coolers and buy yourself a 6870 for 154 AR and free shipping
One crossfire connecter is all that's required but I've read that using both is sometimes helpful, in what way don't know but it wont hurt.
Edit; Those dvi connecters may impede air circulation and in turn increase temps.
2nd Edit; Try taking out bottom card and see what temps you get. That will show you the effect on crossfire temps.
Yes, 2.1 cards are compatible with 2.0 PCI express slots.
Edit; Something to read; http://en.wikipedia.org/wiki/PCI_Express
You definitely should wait for the new graphics cards. They will use roughly 2.5x less power for the same performance. I can't speak to price. Available in:
- AMD 7000 series (Q4 2011)
- NVidia 600 series (Q2 2012)
*Also, I highly recommend you read the article on micro-stuttering which highly suggest no one get an SLI or Crossfire setup. Toms main page.
Get a new card for at least $200 from AMD or NVidia, depending on how long you can wait and your budget.
My guess is that a $250 AMD card near Christmas will have at least 2x the performance of a current NVidia GTX560Ti.
I had those in crossfire as well, and i used therlmaltake DuOrbs on them, having idle temps of 27 C and loads under 60 with a moderate ambient temp (16-22 i think).
Thou at this point i also would not suggest buying coolers as 2 coolers might cost almost the same as a new gpu that will work at least as good.
The thermaltake duords take 2 slots (the gpu slot+ 1 extra slot).
The third slot can be used but you have to remmber the air movement will be significantly worse if you do that (i have a tv tunner card, but its quite small).
Hope this helps a bit.
this from zalman usa:
In regards to your question, the following cards from Zalman are compatible:
VF2000 LED, VF950 LED, VF770, VF900-Cu LED, GV1000 Z-Machine, and VF1000
As long as the coolers can run one-to-one (one VGA card + one VGA cooler) as
normal then doing crossfire format is fine.
