Inno3d RTX3080 Frostbite

Should the supplied Aphacool block be cooling the memory on this card? Card is throttling with the RAM hitting 110C.

Secondly, there is a weird 3-pin cable coming off the block.I assume for RGB but it doesn't look like any motherboard header. Where should this go?

 

[MikeTimbers]

OK, so the little cable is an Alphacool only connector that needs an adaptor to connect it to any motherboard. Or to buy an Eiscontrol (unavailable in the UK right now)

An adaptor cable for mainboards is included in the scope of delivery. If your rams are such hot, something is going wrong. Disassamble the block, and check the imprints on the heat conducting pads. You may have used the wrong ones or have a package problem. BEst would be if you can make a picture of the thermalpads.

Card is factory assembled with the Alphacool block. I have disassembled but didn't take pics. I've ordered new pads as the existing ones did not look good and there was way too much thermal paste on the core. I've also ordered an Eiscontrol as even if I had the adaptor my motherboard doesn't do 5v RGB only 12V.

1mm pads yes?

I have replaced all pads with Thermal Grizzly minus pad 8 and the paste with Kyronaut. Temps are down but inspecting the block while out of the machine I have to comment on the chosen design. As someone who's been watercooling for over twenty years I'm at a loss to understand why the fluid when it exits the slots over the core is allowed to go in two different directions. The channels around the core that should be directing flow over the VRAM areas are not getting adequate flow because the fluid can also go in the alternative direction straight towards the exit of the block. With replaced thermal pads/paste, under significant memory load the VRAM is still >30C hotter than the core.

This same result was shown by kitguru's comparative testing of the Alphacool block vs the EK block.
