realmad37 I agree also, we need some solid evidence man, although it seems like a good idea, we need some proof first before we go waste money on pci brackets and some good quality fans, hope this does work, because anything that lowers temps is good in my book
BlackKnight.KTN Where did you find the HF bracket and is it a big improvement switching to the HF bracket? From the looks of it, they just made the grill bigger
hething Im creating evidence.. Im testing temps in 4 scenarios. 1. Idle without fans 2. Load without fans 3. Idle with fans 4. Load with fans Im using afterburner and folding to get the 99% usage. Cards are all running 825/1650/1900 @ 1087mV
Outstanding! If you would, please include your ambient room temperatures as well. Very nice clocks on those cards!
What kind of fans are you using? Are those low RPM fans?
Cool Idea BR worthly!
Question......How do they incease RPM along with temps? Do you have them pluged into the motherboard?
hmmmmm..... ideas coming to mind..... perhaps... yes, I'm now thinking of buying the swiftech GTX470-HS and gpu block for each of my cards (3x 470 SC - $300 total) as well as the backplates from evga. though I only need one backplate I think I'll buy three of them for the fact that I want them all to look the same. what I'll use: 3x Swiftech GTX470-HS 3x EVGA GTX460/470 backplate 1x COOLER MASTER R4-L2R-20CR-GP 120mm Red LED Case Fan 2x generic slot covers same basic principle as the front one that was posted here but I will add water cooling and increase the amount of air running over my entire board by eliminating the stock shroud that comes with the card due to the fact that I have two more of those fans inside my case that I positioned directly over my cards by cutting out the mesh screen on my HAF 932 and installing a 12x12 piece of acrylic where it was. I then cut out two holes over my cards and drilled in the mounting holes for my fans' screws. just for an idea how much this helped, I removed the shrouds from my cards, keeping the original heatsink and fans intact and I now see ambient temperatures of about 45c playing BFBC2 on max settings with the cards' fans at 75% (noise reduction). I expect that, on water, my cards will hold a steady 30-35C under load thanks to hething's idea
Well, I tried this method, pretty much as the OP did. My results? Keep in mind it is VERY warm here in IL today, nice Fall Indian Summer going on. About 31 C Ambient temp in here at the moment. I'm using 2 GTX 470 in SLI and a GTS 450 for Physx. Testing using Furmark... No fans...Top card hits about 99 C (TOASTY!) 1 fan at the end of GPU's...Top card hits 94 C. 1 fan on the side of cards, 1 fan at the end...Top card hits 91 C. Certainly an improvement! Keep in mind, again, it's on the roasting side of temperatures in here already. It'll be nice once Fall decides to return...
Alucard666 I may have to try this one out. that seems like a sweet little mod.
