No I sold one card when I got the cooler, must update sig!
1st card finished with cooler attached and appears ok. Set the fan to 50% and the silence is golden.
Ran a 30 min Valley benchmark with 50% fan, 1100 core, 1600 mem, 1.15v.
Core temp reached 52 and the vrms were 79 and 70. Haven't messed about with my case cooling, I'll wait till the 2nd card is insitu.
I just can't believe the lack if noise , I even quickly tried at 90% and it is slightly louder bit still very very quiet.
Now to try crossfire

Both cards with acceleo's now in the case. It is a very tight squeeze and basically both cards are nearly touching. So far temps are not too bad, although keeping an eye on the top card vrms, and the lack if noise is great.
I'll need to find a way of getting some cooler air to the top card, I was possibly thinking about rigging an Air Penetrator fan just behind the cards and forcing the air through. Air flow through my case is generally good but the cards are so close now.
Quick question to any mods, why are my other posts not showing yet?, cheers

Meh, they are both rubbish, can't compete with my new Ice-q@24c.
Oh that's right, the Ice-q's vrm sensor is stuck@24c.
I think your going to have to take a saw to your side window matt to give Pete a run for his money, failing that some fans reversed on top of the AC minus it's shroud, could be worth a go, I know you like a fiddle
Cmon the AC's!
Oh, n well done the Peter's!

Dirty Pete with his dirty 'Peter' only wins because he has more fans than Justin Bieber.

I gots options baby
Heaven 4.0; 2x92mm with side fans disabled:
The side fans make a bit more of a difference when clocks/voltage are higher, but not by a massive amount.
Things done changed since my last card for some reason...

Well there we are.
I'm very happy with the temps, but I do recall seeing at least double the advantage when adding side exhausts on my previous 7950.
Then again, I also recall getting noticeably worse results despite using lower clocks and voltage, so I'm not complaining
Fwiw, I think I was a bit more generous with the thermal adhesive this time round.
If there are any other tests you guys would like me to run (except furmark) or there's anything you're curious about that I haven't covered, let me know
***EDIT***
I recently tried a pair of Scythe GT1850's mounted on the bracket underneath the cooler and found that at max speed, they equaled the VRM results of the best configuration here give or take a degree or two and lost out by around 6-7 degrees on the core.
It's a much more convenient solution and takes up a total of 4 slots with the fans installed.
Here's a pic:
Fear not, TL;DR guys! It's pretty much just pictures in there
First off, the usual cleanup operation involving a rubber eraser on VRAM and VRM's plus some electrical insulation tape on a few spots just in case.
The heatsink will never touch these points, but better safe than sorry eh?
Next, I placed Akasa tape on certain spots where I'd be placing heatsinks.
I'd pre-prepared the VRAM heatsinks with neatly cut Akasa tape beforehand.
Now to apply some Alpenfohn thermal adhesive to the 'beast'
I think I put a little more on after this pic and it got a good spread when I placed it.
This stuff sets pretty quickly. No 5hr/overnight job here and it ain't gonna fall off either
It's useable within an hour or so and dries in a rubbery way.
I then popped on the rest of the heatsinks shortly after.
Main heatsink installed using Gelid GC Extreme thermal paste.
Scythe Kama 92mm PWM fans cable tied to ze beefcake.
Note the foam spacers. These help reduce the deadzone as well as provide an anti-vibration measure.
I attached them with Akasa tape.
Installed!
Only a very small amount of pcb sag/flex.
The PCIe cables help a little, but they aren't taking any major weight. They're cable tied to the bottom of the 5.25" bay.
It's not a lightweight solution by any means. If installed properly it's fine.
Why did they send me TY-140's instead of TY-147's? Why?

Can you see how far back from matt you can get when throwing it at him to knock him out when he says he's going to get one.
Only had a quick skim of the data as I'm off home now and will have a good read through later tonight.
I will never cheat on the accelero!

I can throw pretty far. I'm willing to find out just how far

Great results Pete. Thorough as usual.
I was hoping you could show us some pictures of the different fan setups you were using, if its not too much trouble.

Thank you, sir.
I did show pics of the different fan setups, it's just that I was lazy and didn't bother to remove anything when testing.
All I did was disable the side or bottom fans for whichever test

Sorry what i meant was i wanted to see pictures of the actual fans on the gpu in the case, how it looked etc. Don't worry though if thats as big a pain in the ass as i expect it is.

Maybe I'm not following you, but the bottom two pics show the fans on the GPU in the case.

You did a real goob job pete, now i can actually see it.
That vrm sink is so beefy. I just wish the peter looked like the accelero and id snap it up in a heart beat.
Great pictures and great summary as always.
