7811 FX + Coollaboratory Liquid MetalPad?

HI folks,

i was just wondering what kinda heatsink paste is applied to the 7811fx gpu and cpu. You guys think it's a pretty potent one or does a change to a Coollaboratory Liquid MetalPad would do any good?

 

They put some kind of greyish thermal putty on the CPU, on the GPU
thermal pads. You might try liquid metalpad on GPU which will melt and
adjust to the gap between hitsink and GPU. On the CPU go with Arctic
Silver 5 or Arctic Cooling MX-2

 

so what youre basically saying is that they left a little space between gpu and the heatsink or what?

 

That's right. Some folks even making copper spacers to feel the gap between the GPU and the hitsink. It's the very hard work because you have to adjust the thicknes of the copper shim very precisely to this gap. The finish of such shim must be very smooth the mirror like. You can use the thermal compound to bond the shim to GPU and hitsink. The copper is good heat conductor, better than thermal pads.

 

now i got your meaning. So they put one of those thermal blue rubberpads between heatsink and gpu, which are not the best mean to transport the heat away fron the gpu? So putting a Coollaboratory Liquid MetalPad on the gpu, then a copper spacer and then a Coollaboratory Liquid MetalPad to connetct to the heatsink, right? Have you got any idea how much cooler teh gpu will run by this?

 

and yeah, why are they designing it this way anyway in the first place? Wouldnt it make the hell a lot mire sense to have it designed like the cpu?
Direct contact between cpu and heatsink with paste?

 

You don't have to use the liquid metal pad and the copper spacer together. The liquid metal pad is thick enough to use it alone. this is better heat conductor then the ordinary thermal pads. It is another variant of thermal pads. As I remember right it is about 2mm thick, so it will fill the gap between the GPU and the hitsink without problem. The copper spacer is used instead of the thermal pads or the liquid metal pads, because copper conducts heat most, the difference in temps is 10c I guess. There are few threads about the copper shims on this forum, and how to make them.

It is impossible to put the cpu and gpu on the mb in the same plane and at the same time use just one hitsink for both, so that's why they use thermal paste on the cpu and the pads on the gpu. In order to use just paste on both, you have to use two independent hitsinks, one for cpu and the other for gpu.
