Slot covers to hold the fans in? That's a new one thumb.gif

How are your VRM temps?

Do you think the accellero coolers are inefficient because so much of the fans are off the card itself?

On the torture test they reach a max. of 100°C (previously 115°C).

Yes, the gpu fan connector is a regular 4 pin pwm fan controller, you only need an adapter.

Another test to improve VRM cooling based on copper ram heatsinks:



Unfortunately the thermal adhesive didn't survive my previous test, so i needed some help from my approved slot cover:

Man that makes me sad to see your vrm Temps at such an level :/.

Maybe you should do cut the stockcooler like me and place it again on the pcb?

And the Backplate cooler is getting really crispy on my card, it takes a lot of heat away.. If you have any chance to put it on then you should do it.

Maybe you can install it on another slot with an PCI-E raiser cable?

Have you considered soldering those copper heatsinks together? The the joints from the solder I use in plumbing is stronger than the copper pipe it bonds. I use "Bridgit" silver bearing solder and "Laco" flux. When I saw that pic of the heat sinks in the vise, soldering came to mind. You would need a torch, flux and solder. I don't know that electical solder is suitable. As soon as the soldering is done you can wipe the surface with a cotton cloth rag and then it wouldn't be hard to buff off the very thin solder residue.

@Phronesis
Unfortunately the backplate don't fit in my case, could you please test Furmark for 10min and post a HWInfo screenshot?

@Jericho941
I guess it's more of a design issue with the VRM placement and VRM count, all passive heatsinks i tested so far were overchallenged with the thermal discharge.
It needs active cooling or a heatpipe attached to a bigger heatsink.
post #108 of 133
something I noticed when measuring for heatsinks, the driver mosfets are a bit shorter than the low side and high side mosfets.. I would guess about .010/.015 thousandths of an inch.
I think if you split up the heatsinks, leave a little gap where they could breathe a little or drill some strategically placed holes so air could get to them and or escape, your temps would go down a bit..

They should be cooler than the stock mess that was on there. anyone have reference temps under load?

I know, thats why I said that you maybe could get an PCI-E riser cable for that and place it on an empty slot so the backplate can fit, I've seen some for PCI-E 2.0 but can't find them right now but I guess you can do it, it was about 15€ or so.

And well, I don't do Furmark anymore I've heard a lot bad things about it and I guess Firestrike should be pretty good to, the GPU ran @ 1350 Mhz and 1,150V and the Memory was untouched, Powerlimit raised by 50% so I think that should suffice to put some heat on it.

And maybe you could try to put the Fans to the PSU instead of the PCB, this should put some heat away to?



Edit:

I pushed the card to the maximum, 1,4 Ghz GPU and 2,25 Ghz Vram

I think I won the silicon lottery biggrin.gif

Try messing with your voltages/power level some.

14743 gfx score is my best so far.
