I replaced my His cooler with a Club3D cooler 7850

Hardware GPU

Hey everyone,
I wanted to do this log a long long time ago but just haven't gotten to it yet.

Quite some time ago i opened this topic 6850 on 7850
And i did it ;)
so here are the pictures and the story.

i first bought a broken Club3D 6850 for cheap just for the heatsink

the upper gpu was my HIS 7850, the lower one is the Club3D 6850 i bought.

So i first took off the coolers and cleaned them really good.

Then i switched the fan connections on the Gpu's themselves

and i tried to put it on however it did not fit right away, so i needed to modify it abit.

The tube was a bit too big so i made a dent in it with the side of a big screwdriver

One capacitor was also a bit too tall so i cut a little piece out of the fins with a dremel

And i cut away a small piece of the shroud.

Now the temps right?
YES

Idle stock cooler = 41 degrees Celsius
Idle mod cooler = 39 degrees Celsius

So not worth it for that..
But now the load temps
These temps were directly after a full Unigine Valley Benchmark

**Load stock cooler = 79 degrees Celsius
Load mod cooler = 67 degrees Celsius!**

Thats a whopping 12 degree difference!

now the noise levels.
the noise with the stock cooler was a lot!
the noise with the mod cooler was a little

in my opinion it's more worth it because of the noise decrease than the temps haha
but it was a huge succes!!
i also managed to get a higher overclock because of the lower temps (the temps are 75 now with 1210core 1150mem OC)

here stock

Wow that HIS heatsink looks crappy. Is it just me or does the actual heatsink part of it look like a slightly warped, stock intel CPU heatsink, with a copper plate attached to it's bottom. lol

As for the mod. Seems like way too much trouble, IMO. Would have been easier (and way better) to just purchase a used 120mm AiO liquid cooler, and slap a kraken G10 on that thing. Idle temps would become your ambient room temp, and load temps would never exceed 40c. (UNLESS your house is abnormally hot. lol)

i did similar with my 7950 i replaced the stock with a gigabyte 3 fan cooler.

all was good until i realised the fans wernt actually spinning,may have cooked the card fml

Looks just like what you said! I did want to say though that HiS' new cards (at least my R9 270X) have very nice, high quality heatsinks with metal shrouds. :P

i-am pretty sure i can't get a used 120mm AiO liquid cooler and a kraken G10 for 10,- euro's.....

And i don't have room for another 120mm rad

heh...
