Heres our victim: A power Color 5850

Image



Heres the back, where i have to remove the screws to seperate the the board from the reference cooler.

Image



all seperated, you can see where the cooler hits the GPU and where the thermal pads are:

Image



Here you can see i need to remove about 8 screws(more on that in a minute), so I can seperate that black metal plate from the rest of the junk, so i can reinstall it.

Image

Heres the GPU all cleaned of its cheap goop. All shiny!

Image


Heres everything separated (and if you notice on the bottom piece, i broke it, 2 screws would not come out, and the plastic actually broke as i was trying to get them out! This cooler better work now! ) Its only a $300 video card, no biggie :)

Image

heres the back plate, reinstalled.(the part i wasnt sure would work)

Image


screws back in!

Image


View from the bottom. As you can see on the right, some of the fins hit the DVI port, I have to cut/bend about 11 of them to get it to fit)

Image

close up of the bottom (so you can see how close it sits to the base)

Image

view from the top, so you can see the clearance for the heat pipes.

Image

finally, installed!!!

Image
itrs running like a champ.

If you remember i cant run the reference fan past 40% because it sounds like a jet engine. This cooler, I can run at 100, and you cant hear it at all! Its silent!

Now on to the quick stats:

Reference cooler:(fan 40%)

stock is 725/1000 Volts 1.08

I stopped at 850/1170 temps GPU/MEM were 62C/71C (100% load test)thats about as comfortable as i was willing to get. Volts 1.175

With the Turbo Pro temps went to 46C/68C

quick test I OCed to 925/1200 and it was 51c/72c.

loving it. Better cooling on GPU, it keeps the Mm/vrms as cool (most aftermarket coolers are having a hard time keeping the mem/vrms cool without the stock baseplate) as the reference cooler, and silent!

4 hours of playing company of heroes and borderlands last night with the 875/1175 OC, and the GPU never broke 40C and the ram/vrms 42C

Edit: i forgot to mention. Tighten all the screws well. I was afraid at 1st, and got some crappy temps, when i tightened everything as best I could, temps were great.

Very nicely described. :) The metal plate on my HIS 5850 was a little bit different and got in the way of the heatpipes. Using the TTPro fans on an Accelero S1 I've seen that the fans cool excellently even at just 10% speed, though I'd had to run MSI Afterburner or a similar tool to get below 20%.

Nicely done. I just might try it myself on my card if I ever get motivated enough :lol:

So that's why they don't list it as compatible with the HD5850.

Yes. The GPU on the 5850's is a little closer to the front of the card then 5870's. Thus the coverage problem, it was an easy fix though, its thin sheets, and easy to cut, took all of about 5 minutes.

I would like to point out that:

1. You'll need to bend the heatpipes in an upward direction so that it clears the baseplate, I also changed the position of the TTPro's base.
2. You'll need a 10cm Xfire cable to clear the heatpipes.

And OMG they just drowned that base in MX-3 lol :roll:

And for some reason GPU-Z lists the fan speeds as ~650000rpm :lol:

1. Ah, no you dont. I did not bend anything.
2. Correct.
3. Yes they did :)
4. Its because there are 2 fans plugged into one header. GPUZ does not know how to read it.
