DD 4870 Block Problems

post #1 of 5
Thread Starter 
Alright, so finished up installing my danger den 4870 water block... booting into windows to check temps in rivatuner... core temp: 35C, mem 95C, vrm 50C. --And these are idle temps.

What the heck is going on with the memory chips? I assume it must be a contact issue... but Ive tried seemingly every combination of screw pressures around the mem chips. Best I could get out of it was around 90C on the mem, while the gpu core still idled around 35-40C.

Using the thermal pads that came with the block.

Was there thermal pad paper?
Sounds like the contacts are not lined up properly or its not seated flush, more impotantly, verify your water is properly routed through the waterblock.

Thermal pad paper? Not sure what you mean. I did say in my first post I used the thermal pads that came with the block.

How can the contact possibly be this bad? Aren't the mem and vrm's supposed to idle around 35-40 with these FC blocks?

I can't see and visible bending the the board either.

Okay, so here's an update.. After playing around with the screw tension a bit more, I've gotten different, but still bad temps..

gpu core:35C
mem: 46C
vrm 67C

these are idle. Running F@H, gpu and mem are still fine now, but vrm temps gets to 100C...

Okay, problem solved! Turns out I put the thermal pad on the wrong part - I put it on the vitec and pulse chips - not the small little VRM's... Now they run 65C under load (furmark)
