[Official] AMD Radeon HD 6850/6870 Owners Thread - Page 486

post #4851 of 6939
Hey all, I wanted to share my experience installing a Arctic Cooling Accelero S1 Plus Cooler on my XFX Radeon HD 6870. First off, if anyone is going to use this heatsink and wants to use the small memory heatsinks that it comes with, do not use the thermal adhesive it comes with! I first tried using the included thermal adhesive and after 3 hours it was still just as wet as when I first applied it. Instead I bought Arctic Silver thermal adhesive, 2 hours after applying it, it was set.

Here's the finished product, kind of ugly but my idle temp has been lowered by about 18 degrees. It sits around 36 degrees with the fan at 1500 rpm.

450

The stock cooler had a strip of grey thermal material across 4 very small chips, I wasn't sure if they needed heatsinks but I didn't want to leave them off so I cut down some small blue heatsinks to cover them. I had to take the black plastic bezel from around the heatsink, I couldn't route my PSU cables around it with it on. I zip tied an 120mm thermaltake fan and put some small rubber washer under the screw holes to keep the vibration down. I also had to remove the fan on my side panel because of it's size, now thanks to my CPU heatsink and this one my side panel has no fans mad.gif. This thing turned out to be a much bigger hassle than I originally thought but it was well worth the temperature drop.

Lucky you stuck those blue ones on, Thats for the mosfets/VRM and they get hot. Especially when overclocking.
The small blue ones might not be enough so be sure to monitor them since you dont want one of them burning out and destroying your card.

It has to be better than the strip of stock grey thermal material that was on it, it only had plastic above it, haha. But thanks, is there any way to monitor how hot they get?

thermocouple/thermistor
probably not worth bothering with

You can monitor the VRM temps with GPU-Z under V-Reg temp.But it does not work with all cards.

As said GPU-Z other wise if you have easy access to the cards you can stick your finger on one of them.
If it burns you finger you have a problem, If not then its sweet.

Mines got the big stock cooler on them and that gets quite warm to the touch after half a hours gaming.

Well it wasn't even warm to the touch, GPU-Z has VReg 1 at 35C and 2 at 26C so I'm not going to worry about it.

Thanks for all the info.

Well done, in fact with a huge fan like yours those 4 DrMos are cooled enough (even in oc). The X-Bit Labs, in one of their first HD 6870 Crossfire reviews successfully used an Accelero Xtreme 5870 cooler even without vrm small heatsinks, since the cooling power of its 3 fans was enough even at lower speed:

Even with my VF3000A I have no cooling on the VRM's, all I have is the 8 RAM chips with passive heatsinks and the main heatsink. It does have two 90 mm fans I keep at half speed. During 24/7 folding, GPU temps never go above 55 C and VRM temps in GPU-z peak at just shy of 60 C.

I'm assuming as long as you have a fan directly over the VRM's and your GPU is under 60 C so that your heat sink isn't getting so hot that your blowing super hot air on the VRM's, you should be okay without.

If I recall correctly, when I tried putting 1.3 V through my card to get higher than 1000 MHz core clock, it would start artifacting like when you have a high memory overclock just on 2D clocks and get driver crashes during VLC. But when running Furmark, I would get just white and black specs in the actual fur on the donut itself and nowhere else and GPU temps would hit 60 C and VRM's would sky rocket to 90 C.

TL:DR:

If you're going to be increasing voltage from the stock 1.175 V to above 1.2 V, get some heatsinks on the VRM's, otherwise make sure you have a fan blowing air over the VRM's directly.
