If you refer to my pic, the mosfet is wedged between other standing parts - those heat sinks won't fit between them, I don't think. I currently ghetto rigged a heat sink onto a corner of them and the temps have lowered to 89C! Huge improvement over 106+, but that sink could fall off any second xD

You should be able to cut them to size with a saw.

Lol I meant a pic of the card after you modded it - I wanted to see where the heatsinks were tongue.gif.

I know its not something everyone will be willing to do, but I cut the bottom portion of the stock cooler off, put some TIM on the thermal pad to assure good contact, and pulled the blower fan off the stock heatsink to use the finned bottom plate for VRM cooling. Then I just used a tiny MOSFET heatsink I had lying around for the top VRM and my temps are like 71 and 60c. with a silent 92mm fan blowing on them from my TripT bracket.

Excuse the crappy cell pictures, was just snapping quick shots while I did the mod.

Here you go guys, these are the copper shims I ordered off eBay and they fit like a glove on my 7950.

Just ordered those - hope they fit!

Those are the right L x W for VRMs but the height will be too tall if you have the fan bracket version. If its the plain bracket or zip-ties though they should work awesome thumb.gif.

Another question here. I can get an Antec 620 for $35 or a 920 for $48. Both are used but in great condition. Which would you recommend? Will the difference in noise/performance be huge? I also do have some concern with the 920 being possible too large considering I'm using the Corsair 35D mATX case, but I'm not sure if I'm right in being concerned.

Unfortunately, I only got one of my Zalman LQ320's installed tonight since Dwood only included enough hardware for one bracket (DOH!). I need to figure out what size bolts/nuts I need to do the second card before I can get that one done. I also needed to modify the front of the Arc Midi R2 just a bit (new holes) in order to squeeze in both Zalman LQ320's due to their non-standard 120mm shape.

That said, I'm extremely happy with the results on the primary gpu... THE RESULTS ARE ABSOLUTELY SICK!!!

BEFORE
2 x Powercolor 7870XT Myst in Crossfire @ 1100/1500 after a Unigine Valley run, ambient temp is 26C:

GPU1: 101C Core, 114C VRM
GPU2: 87C Core, 96C VRM

AFTER:
2 x Powercolor 7870XT Myst in Crossfire @ 1100/1500 after a Unigine Valley run, ambient temp is 23C:

GPU1: 43C Core, 89C VRM
GPU2: 81C Core, 87C VRM

As you can see, with only a 3C drop in ambient temperature, the Red Mod on my primary card dropped the core temp by 58C!!! and, it dropped the VRM temp by 25C!!! Ummm... HELLO!!!! RI-DIC-U-LOUS!!!! As an added bonus, the temps on both my secondary gpu and cpu also dropped since the entire system doesn't get as hot! Each of those dropped by about 6C or 7C!
band.gif

Process for GPU1:
1. Added Zalman LQ320 with (2) 120mm Scythe Gentle Typhoons in Push/Pull
2. Added 8 x heatsinks to memory
3. Added 2 x mosfets for the tiny chips on far right side of the card (what are they?!)
4. Added fresh TIM under the stock VRM heatsink
5. Added GELID Solutions Slim 12 PL 120mm Blue LED PWM Fan on Dwood bracket -- these fans are only 15.8mm wide, but they'll push 52cfm!
6. Added GELID 4pin VGA Fan adapter in order to use the GPU's fan header for speed control

Seriously, this is unreal... I can't wait to do the second card!

A few pics...

Can you link the heatsinks/mosfets you bought, as well as the 4 pin fan adapter?
