HD 6970 Thermalright HR03-GT Custom Mod

I decided to change my HD 6970 stock heatsink to aftermarket because stock cooler noise is just too loud, luckily my old HR03-GT that I used for my HD 4870 is compatible with it.

ASUS EAH6970 2GB (factory overclocked to 890 MHz)
3 years old of Thermalright HR03-GT and Noctua NF-B9
Enzotech MBR-C1 and MOS-C1 copper heatsink

Very informative video, thanks!

Was thinking of actually getting those sinks for my VRM's also.

Q:

1. What software did you use for load test ? Furmark ?

2. Have you tried overclocking / overvolting the card ?

3. Did your VRM ever reach under any circumstance > 70°C

4. Is the thermal tape permanent ?

My main concern was that they were too small to do anything but your temps seem very good under load. My other choice was the aluminum heatsinks from Arctic Cooling

@steinmil

1. Heaven DX11 Benchmark 2.5. I don't use Furmark (aka GPU killer)

2. Haven't tried OC, because the purpose of my build is silent setup.

3. Afaik mine never reached above 50°C

4. No.

For heat transfer, Copper > Aluminium

(FYI, the original ram heatsink that come with HR-03GT is made of aluminium)

How does the increased temperature in Vreg affect the card? What's the max temp for it?

My HD 6850 is reaching 90 degrees w/ stock cooler so im thinking of getting a aftermarket cooler, but I got shit airflow (like almost no airflow). Is this cooler gonna be best for me?

[ThunderZTRM]

@LRoyz Stock cooler can handle the temperature just fine, but it's very noisy. Around 80 degrees is normal. HR-03 GT is an old model, I'm sure there's better cooler out there (e.g. Shaman). If you're going for Thermalright heatsink, it is recommended for you to buy the heatsink for the VRM separately.

Looking at the HR03-GT, does it appear to you that there is room to install the VRM R5 onto the 6970 or 6950?

[ThunderZTRM]

@kewlbreze77 According to ThermalRight, VRM R5 is incompatible with HD6900 series

not bad at all :)

omg sold me on the Enzotech MOS-C heat sinks, Im planing on puting them on my choke's and other mobo chips, maybe one day ill mess with my xfx6870 twin fan but it runs cool, Ill post a video in about three weeks of my mobo with the copper heat sinks installed.
