Title: Building 4x 7970 rig and having heat issues. Post by: baritus on May 07, 2013, 04:06:18 PM Hey guys,
I'm building a 4x Gigabyte Radeon 7970 rig in a Corsair II case. The cards peak at 77 when there are two of them, but when I add a third in between, the card temp sky rockets(there isn't much space between one card and another..) Are there any solutions to this? Thank you. Title: Re: Building 4x 7970 rig and having heat issues. Post by: Kalen on May 07, 2013, 04:12:01 PM File or Milk Crates - https://bitcointalk.org/index.php?topic=66432.0
Use PCI-E riser extension cables (powered). Title: Re: Building 4x 7970 rig and having heat issues.

You should get some risers, but in the meantime, try undervolting and/or underclocking the card(s) until temps are safe (under 85C or so).

Most cards will automatically throttle at 100c or so thats the real upper limit... Title: Re: Building 4x 7970 rig and having heat issues. Post by: mt_bird on May 07, 2013, 09:26:35 PM I basically agree with cdog. I try to keep my cards under 85C now, but I've actually run a couple of them in the low 90s for several weeks with no problems. Even if you run the cards around 90C, they should still last a long time (maybe not several years, but long enough to pretty much become obsolete by the time they fail).

When you talk about Corsair II case. What is it exactly? I was looking to acquire a Carbide 500R to host a 3 GPUs rig: http://www.corsair.com/en/pc-cases/carbide-series-pc-case/carbide-series-500r-mid-tower-case.html Could not find any reference to Corsair II case on their website... |
