dan i have a non refrence 7970 by msi, OC edition. My stock plate was different a little, has a big cooler with 2 fans. my stock plate doesnt have fan built in like your pic. i was talking about installing just stalk plate then gluing essentially heatsinks ontop of that plate in order to protect the warranty. so if you take off the sinks they wont damage chips, just maybe takes off a little paint of that stock heat spreader plate.

I have a question. I bought the universal bracket and a refurb h60. gonna MSI 7970 GHZ EDITION 1050. ARE noctua fans worth the extra $? Also, what of the pump plug in destination? should that go to the fan plug in on the 7870? where do i plug in the pump and where do i plug in the fans that goto radiator? lastly would a 3 way pwm splitter cord solve all this or can it carry that much current and be reliable solution?

@aaronlaplante - I don't see why that wouldn't work, though you may find that you get better VRM temps with small sinks thermal taped to them instead of with the stock plate installed. If you have the time to try both it might be worth 5-10 degrees either way to you which will make a difference if you're overclocking. Carefully removing thermal taped heat sinks shouldn't damage anything that would lead to voiding a warranty. The only downside is that you will lose some PCB rigidity by removing the stock plate.

Dan. THats why i was asking why not just mount the heatsinks to that plate, directly above vital areas. you can see where it has been warm before on one side of the plate, why not just sink directly on the other side with thermal adhesive? wouldnt that be nearly as good or not? can you explain?

Regarding the noctua fans, for this application, I don't think that they're worth the extra $. The pump should be plugged into 12v straight from the PSU, use an adapter if required as you'll want it running at a steady 100%. You may use an adapter for the fan you mount over your VRM which can be throttled using a fan profile in Afterburner if you'd like, or you can plug that straight into 12v also for a constant 100% depending on noise. You may want to use a fan controller on your radiator fans to find a speed at which they are quiet yet keep the GPU at an acceptable temperature.

For the heat sinks on the stock plate, I'm still slightly unsure of where you're going to mount them. If you're talking about on the underside of the PCB, on top of the stock plate, but with the stock heat sink removed, then yes i think it's a good idea if you plan on overclocking.

If you're talking about a version of the MSI 7970 that comes with a fancy back plate on the PCB mounted on the upper side of the card then I don't recommend mounting heat sinks to that unless it has a direct thermal interface with the VRM. If you'd like further clarification please upload a pic of your card with a circle around where you're considering mounting your heat sinks.

Reference HD 7950 + H75 = 40-45 degrees Celsius

Sorry all the pics are in the thread.

Seems to be working well with that spot fan. Core never exceeds 47C amd VRM never exceeds 62C

Where did you get your heatsinks from? More specifically the VRM ones.

Just upgraded 4 stock fans from various radiators to 4 NF-P12 Noctua fans. Temperatures stayed the same, maybe a bit better, but I can't hear the system at all. Before it would be like a prop plane taking off.

DAN, i meant the heatspreader that cover s the vrms, and most of the memory, it mounts to the from stock (gpu side), and what of mounting that back on with fans blowing at tthem and mounting additional finned heatsinks to that small ones that are located above the hto parts? im not talking about the backplate, im talking about the stock aluminum black heatspreader.

It's worth a try. I'd definately be interested in the outcome as i run the stock heatspreader on my card to retain the stock fan and provide some cooling to the vram and ram. The way my reference card was setup i had to bake the copper heatsink and aluminum fins that cooled the gpu of the heatspreader. The heatsink looks as if it was providing some cooling to the ram so i would think this would work.
