MSI 6970 re-paste

post #1 of 19
Thread Starter 
Hi there everyone. Im relatively new to overclock.net. I build my first rig just about a year ago now and I have caught the computer bug, always tinkering and planning more builds.

In my rig i have an MSI 6970 Lightning. However i got it from overclockers and it is not the factory overclocked lightning card, has the stock clocks (880 core + 1375 mem). I have overclocked it to lightning speeds. my temps have never been great but acceptable. Recently they have been hitting 72c when playing sleeping dogs for a couple hours. Also i have just been running kombuster and it has been hitting 80-82c in about 2 mins at 1179mV.

I was thinking about reapplying the paste on the card as i have some spare IC Diamond in the house. Is there anything that i should watch out for or keep in mind when doing this. I have looked around on youtube and forums and it seems pretty easy but i just thought i would get some opinions from you guys.

It is farely easy. I did it on my 560 ti and it helped about 5 deg. When you go to take the cooler off make sure you twist it side to side real easy. That will help to break the bond of the old tim.

You could apply new paste without any issues. Just rememger that GPUs don't have a hear spreader over the die so be cafefull with it. They are about as durable as a piece of glass and can chip if you do something wrong.

cheers. TBh it does all sound pretty simple (famous last words), i mean after all i have build a system and done multiple cpu mounts and re-pastes.

I think i may run a bench to get the old paste a bit warm before so i can give it less of a wiggle.

so you guys thing ic diamond will be ok for the gpu then?

I have no personal experience with that TIM but since I read that its abrasive, I probably would use something else since theres no IHS on that GPU.

Something like MX-4 would be a good choice. That's what I have used on all my CPUs and GPUs for the last couple years and it works good.

yer i have heard about the abrasiveness of icD. however i have done multiple installs on my cpu and have seen no evidence of scratches or anything to suggest degradation due to the TIM. I think im going to give it a go with mu ic Diamond as i have it already to hand.

Well thats that done. Went off without a hitch. Didnt even need to wiggle at all.

Soo much gunk on it at stock. Has dropped idle temps by about 5-8c down to 30c. Before after 2 mins temps hit 80c but now i have run it for 3mins and it hit 70 so pretty good so far. havent run it for longer yet but looking good so far.

Seems like your cards TIM was applied qiute bad. I have owned a couple reference AMD cards now and never had idle over 30C or max temp over 75C excluding furmark.

yer it wasn't great. also i noticed that the heat sink surface was no where near a mirror finish and did not look overly smooth at all. so that may have something to do with it.

im watching a film atm and its sitting at 43 steady

mounts can make a huge difference too, and sometimes the mounting systems are less than ideal. I have a powercolor dual fan 7970 that had terrible temps like 90c in furmark with a minor OC

I re-pasted and accidentally broke one of the retention springs/screws, so I simply found some properly threaded screws and attached them firmly to the heatsink. Even on stock fan profile now the GPU won't break 70 with a 1200/1650 OC
