6800 Series Aftermarket Cooling Thread - Page 29

post #281 of 291
I think the lack of response is from no one having one and 6870. Best I can advise you to do is what I did with a cooler I have. Take off stock heat sink and test fit new cooler. If it fits and fits the cooler, great... apply TIM and install as normally. If not, apply TIM and put stock one back on.

Tia.

No idea how much they are in dollars but get an accelero xtreme plus, I have one on my 6870 and they're amazing, reasonably easy to fit and really quiet.

NICE FINALLY i found a place with reviews for aftermarket cooleRS FOR my hd6870 TIME to read xD
post #284 of 291
I have the Arctic Twin Turbo 2s in Crossfire for my Powercolor AX6850s

I'm running an overclock now of 850/1200 and it is stable in 3dmark11 thus far. The memory clock is a little higher than usual, but I don't recall that ever working before I installed this cooler. 1150 is still good though if I happen to encounter instability in games.

Temperature hits 70C in Far Cry 3, highest I've hit yet. The second card is a good 10C cooler. VRM (on 1st card) are a little warm but safe in the 70's. The setup pulls in air from the rear and sides of the case, and exhausts it vertically. My H80 in push/pull has no trouble exhausting the heat set on high.

I have a Gigabyte 990FXA UD3.

It's a squeeze in a 7 slot case, but they do fit if your mobo has that kind of setup. Luckily my seventh slot is on top or else I'd be using USB for wifi.

I just replaced the fan and cooler on my XFX 6850 black edition and thought this would be a good place to share my experiences for others. The fan on my card got very noisy and made unhappy grinding sounds on occasion. I attempted a fix that I will link below, but with unsatisfactory results. In the end I was tired of the whine of the OEM cooler and decided to replace it all together.

First the normal disclaimer: This will void any warranty on your videocard. XFX reportedly has a very good warranty replacement program, so that's the best way to go if you have problems with your fan.

If your fan is grinding, the best thing to do first is to try and re-lubcirate the fan bearing. Here's a great thread on this forum which describes the process for this and other sealed XFX fans:
http://www.overclock.net/t/1320936/tutorial-on-fixing-a-noisy-xfx-radeon-hd6870-fan-note-no-rubber-plug-in-the-back

Unfortunately, this didn't fix my issue so I had to look elsewhere. I settled on the Arctic Cooling S1 Plus cooler for 2 reasons: 1 - I've used their coolers in the past to great success, 2 - My preferred store for cooling components had it for 25% off.

Manufacturer link: http://www.arctic.ac/us_en/products/cooling/vga/accelero-s1-plus.html

INSTALLATION:

Before embarking on installing this cooler, heed my warning: IT WILL TAKE OVER 6 HOURS TO INSTALL. YES, OVER 6 HOURS.

Removing the stock cooler is a simple matter, for my xfx card it was 4 screws on the back of the card under the retention plate and 1 screw on the back-panel pci-covers that secure the plastic shroud. Do your standard TIM removal on the GPU core, and remove the VRM cooler by un-screwing the two screws on the back of the card. Finally, clean off the VRMs in much the same way. Tada. No, you can't keep the old VRM cooler, it's too tall.

The cooler comes with a thermal epoxy that needs to be mixed. The directions plainly say mix the two packets of goop together for 5 minutes, then install the new VRM and RAM heatsinks in about 15 minutes.

Here's the part that sucks: The epoxy will take 6 hours to cure. You have to leave the card alone while the glue sets. My suggestion is to start the install before going to bed and then complete it the next day. I let mine sit for about 11 hours (after 4 hours the glue was still wet). My understanding is that the newer version of this cooler and other AC coolers with epoxy have a new mixture that should only take an hour or two to cure.

Once that's cured, installing the cooler itself will only take 3-4 minutes. Follow the directions to install some 3.5mm spacers onto the cooler, place the videocard onto the cooler, and screw down the 4 screws. Incredibly easy, just follow the directions.

RESULTS:

First, you CANNOT run this passively. The VRMs and GPU will get too hot under load. I had two fairly quiet 120mm fans which I attached with some double-sided foam tape directly to the cooler. They sit at weird angles, but it gets the job done.

Running Furmark burn-in with two fans led to a temperature of 59-60ºC at a noise level that was imperceptible above the other fans in my case. Quite the departure from the hairdryer noise from before.

TL;DR: Arctic Cooling S1 plus works but needs one or two 120mm fans. Installation takes ages for glue to cure. Results are 'happy smile face'™ in temp and noise.

Your tutorial is spot on for sealed fans, either I didn't add enough lubricant or my bearing was too far gone. Glad to hear yours is still working after the fix.

One more quick note about this cooler: It will obstruct your ability to easily remove the 6 or 8 pin pci-e power plug(s). I just broke the lever off of my plug when I took the card back out. Thankfully Antec makes some good plugs that stay in place with just friction.

Second note: the cooler itself will take up the same 2-slot width. With standard 25mm fans, it will take up a total of 4 slots. So this would be a no-go in most cases for crossfire unless you had some wicked method of pushing air into the cooler from the edges.

Nice Good job!!! MY only worries is the VRMS :/. BTW... there are no mini heat sinks for the VRMS and Ram chips with the stock heat sink on!.. i wish that this cooler could of worked or at least some other compatible cooler out there :/. I think the card and its small PCB is the problem for after market cooling :/ but it's a great card smile.gif
HEY grab 2 90mm fans and zip tie em on the heat sink they will fit flush!

Well I didn't have any 92mm fans and I don't think any would have the proper noise/airflow ratio that would meet my needs. Sure you can get quiet fans, but unless they move air, they are pointless. Case in point, I originally tried using a low-power 1200rpm fan from fractal design. Spinning full-speed, I was barely able to detect any airflow out of the bottom of the heatsink and the load temps increased.

Yeah the memory heatsinks are totally worthless, they don't generate much heat as designed and I don't OC. The VRMs are probably safe at much higher temps, but I've seen enough scorched PCBs over the years that I like having them cooled. I could smell how hot the VRM sinks got when I tried running passive.

Looking at the installation document for the Icy rev2, it is a bolt-on replacement just like the cooler I purchased. Here's a video describing installing the cooler on your card: https://www.youtube.com/watch?v=JkZ_hvgbneM If might not be 100% the same, but you can use the small heatsinks as shown on the VRMs.

Quick note: verify your fan-connector. My card only had a 2-pin header not a 4-pin. If your card is like mine, you'll have to use the included 4-pin molex adapter and hook the fans to your power supply and not the card.
